I upgraded to 11.10 from 11.04 and my wireless stopped working.
STA drivers were installed and were activated (By default )
I have Dell Inspiron 640m and network card is Broadcom 4311.
I did following and it worked for me.

From Ubuntu software center

1. Remove bcmwl-kernel-source.
2. Check if firmware b43-installer and b43-fwcutter are installed. Install it if not installed.
3. Restart the computer.

Same thing happened when I upgraded to 11.04 and everytime during package upgrades if I upgrade wireless drivers it would stop working.

Hope this helps.

Tried every thing I could find all over the net, but my wifi problem on an Acer 4820T with Oneiric Ocelot just would not resolve. It would work on a whim and often not work at all.

Easy solution in the end was to ins re-install Linux Mint 11 Katya. Now my wireless works flawlessly!

Hi all,
I happily fixed my Broadcom 43224 wifi issue, I just removed the proprietary STA driver to keep only the brcmmac free driver, and it's far better.

Hi, i have installed Kubuntu on my Asus F5R and my wifi doesnt work. (i also tryed with ubuntu and xubuntu but no way to use my wifi). I followed several threads, posts and whatever i find in internet but i haven't solved my problem. My notebook has the wifi light on but ... it seams not working anyway.
(I tryed with my old usb wifi netgear adapter in order to chek if the wifi signal was ok and it worked...)

I'm posting you some datas and hope you can help me with this:

what does it mean? is bcmwl putting my drivers in blacklist by default?

Thank you very much

UPDATE:
I removed all packeges with tags: bcm, broadcom and then typed in the terminal:

sudo apt-get install firmware-b43-installer
sudo modprobe b43

wifi started working. i can't understand why this method has worked now and not yesterday ? i did the same at least twice yesterday...

There were no hints to my problem with the Lenovo U160 and Broadcom 4313 given here. In case anyone has the same issue here is the fix. First use the kernel supplied driver, don't install the STA. Then edit the blacklist file, /etc/modprobe.d/blacklist.conf and blacklist the acer_wmi module. Hint, open file as administrator with gedit, save after changes. Then rmmod acer_wmi. If rfkill list all shows anything blocked issue unblock all. Your Lenovo U160 will have great wi-fi working. Cheeers! BTW, it worked in Mint 11 as well, same deal. My original posts are on page 50.

@ bog_alt

You need to remove the bcmwl driver you are trying to use. It will not work with your wireless card.

open 'Additional Drivers' if it is listed there click on de-activate. Do not reboot when prompted. Instead open a terminal type in and run
sudo apt-get install b43-fwcutter
sudo apt-get install firmware-b43-installer

if any errors eg- cannot be found - then edit the sources list in Software Centre make sure the first 4 boxes under the Ubuntu Software Tab have a check mark in them. Then run the commands again.

When that has finished, reboot, unplug the USB dongle and your wireless should be working.


Good luck.

Have typed the above then noticed you got it working. Oh well.

If network-manager shows "device not managed" (German: "Geršt ... nicht verwaltet"), do this: http://ubuntuforums.org/showpost.php?p=7040998&postcount=6 , but the config file ist now:
/etc/NetworkManager/NetworkManager.conf
And after that
sudo service network-manager restart, and wait 2 minutes, because directly after restarting the service, it still showed that the device is not managed.

Finally solved my missing wlan functionality from just a distribution upgrade (I think it was up to 11.04)! I am happy :)

Yes, you have posted the list of loaded modules, but neither b43 nor wl are loaded. What driver do you want to use? And check that only the other module, that you don't what to use, is blocked within the config files in /etc/modprobe.d/ , please.

@auftable Thanks, that's really useful. I am VERY new to this and do not actually know what I want to load and was hoping for advice as a lot of what I've read here and elsewhere is contradictory. I'm happy to take advice and sort of need leading through it.

Thanks again.

Ok, what kind of wlan will you use? If you use it only at home or other private networks, try b43/44 first. Only if that fails or if you also want to have access to a wlan with user accounts, for example at a university, try the STA driver.
Only for b43/44:
Find out your wlan chipset: http://linuxwireless.org/en/users/Drivers/b43#Supported_devices .
Install, for example b43-fwcutter and firmware-b43(-lpphy if low power version)-installer with synaptic. Before, deinstall packages beginning with "broadcom-sta-", if installed. Reboot, try "sudo modprobe b43". If only then something works in the network manager, write a "#" in front of every line in /etc/modprobe.d/broadcom-sta-common.conf (edit with sudo gedit).

Btw., what's you current status at all? Error messages you get? What is network messenger showing?

Thanks for all the help. I tried a number before getting my WiFi back. The best help came from this link http://linuxwireless.org/en/users/Drivers/b43#Supported_devices which identified which driver would work, and has some useful instructions.

My hardware is a Dell Inspiron 1521 AMD Turion x64 Dual core 1.6Ghz, 4Gb RAM, 120Gb hdd. The wireless adapter is Broadcom BCM 4311.

I had Ubuntu 10.04 installed, along with VBox 4.1.4. I had tried 11.04 in a VM, and decided to take the plunge and upgrade. Upgrade went fine using an ethernet cable, but the wifi disappeared as soon as I had activated the STA driver. I tried several fixes from this thread and ended up with no networking at all! That was with the b43 LP-PHY driver. In every case I found that with the driver removed, the card was visible, but showing as disabled, to the network manager utility on the task bar, which also showed Wireless Networking Enabled. With the driver activated the card was not visible and the Wireless Networking Enabled/disabled function had gone.

After trying various solutions over 3 days, I gave up and did a clean install from a CD using the x86_64 version. This time when I activated the STA driver it all worked fine. The bug seems to be in the download for the upgrade. My 64bit CD image is dated 5 Oct 2011. I'm going to do tests with my old Inspiron 1300 to see if I can replicate this, as it has the same 4211 card.

Again thanks to all those who took the time to post fixes. :)

I think there was a dialog when upgrading wanting me to chose either to keep the old version or chose the new version of a configuration file, and it was something with "network-manager" in it. Maybe that's why STA was deactivated when upgrading but works from a fresh 11.10 system. This could also explain sid1950's problems and solution.

Summarizing my install experience on a Dell Latitude D630 running Oneiric and the built-in Broadcom 4311 wireless device:

0) Connect to a network via a wired connection. :)
1) Installed firmware-b43-lpphy-installer via sudo apt-get install. Got some type of "installation failed; device not found" error message.
2) Ran update-manager, which populated the software center.
3) Removed firmware-b43-lpphy-installer and installed firmware-b43-installer via the software center.
4) Commented out the blacklist b43xx line in /etc/modprobe.d/blacklist.conf.
5) Executed "sudo modprobe b43". (Yeah, I could have rebooted.)

Clicked on my network status icon and I can see -- and connect to -- my wireless network. Success!

[Updated at 13:01 to add: But upon reboot, I have to type in "sudo modprobe b43" to enable my wireless adapter, every time I start an Ubuntu session. I think there's something else I need to do so that it would come up automatically. But I don't know what that is.]

I have an Acer Extensa 4420 with a Brodacom BCM4311 integrated.
After a couple of hours searching around.. i decided to ask the forum/search the forums (dont know why this was not my first choise, it usually is.. ).

I did exactly what poltr1 said and worked flawlessly. I dont know if ill have to "modprobe" my card on reboot, since i havent rebooted yet.

i will update on that.

BTW @poltr1, you could make a small script and run it on system startup.. its not perfect, but it would solve the issue for now..

Thaks for the mini tutorial !!

You should be able to automagically load the b43 module at boot by adding it to the modules loaded at boot time. You could add it manually to /etc/modules or in the terminal do (one time):


sudo su
echo b43 >> /etc/modules
exit



This will require your password which will not be echoed to the screen, just press enter when done then try a reboot.

If you are using Ubuntu 11.10 you may have one additional file (folder) that is "blacklisting" the b43 driver. See this page for details.

Thanks for the tip, but for i didn't had to "modprobe" again upon reboot.

maybe this is because i have an integrated card and not a usb-boundle ?

anyway, thanks.

This kind of things can be hard for a new user, this was a laptop i just made a fresh install for a friend.. but happily it didnt discourage her.. :D

i guess this is the kind of thigs everyone says: first step, search the forums lol

My problem with this driver was that it was extremely slow, It did actually work but just terribly slow.

I think im going to black list all the linux broadcom drivers for my card and try to install the windows driver via ndis wrapper.

i will post my success or failure here in this thread just in case anyone else is having the same problem i did.

Wich shows that the brcmsmac driver is currently in use on my system for my broadcom 43225 internal card, However in the driver install gui it says that a propritary broadcom "sta" driver is installed by default and in use.

http://www.postimg.com/54000/photo-53021.jpg

The brcmsmac driver is an open source driver wich is NOT PROPRITARY in any way shape or form, It was released by broadcom sometime last year as an open source linux driver as you can read here - http://linuxwireless.org/en/users/Drivers/brcm80211

http://lwn.net/Articles/404248/

So why is ubuntu 11.10 saying i have a propritary driver installed when i dont?

Thanks for all the help on here but I'm afraid to say that none of it actually solved the problem. It has meant that the learning curve was steep and very useful.

The most excellent news is that I have managed to solve the problem...new hard wear.

After a few searches I came across https://www.thinkpenguin.com/ on there they have a whole load of useful stuff, including their 802.11G USB Wireless Network Adapter. I ordered on which was still very reasonable even with postage to the UK. Under £40 and no more problems. It's a lot cheaper than buying a new PC or a copy of Windows.

Because you do. What Broadcom has released is not ready for Canonical to put in Ubuntu yet.

But its open source so obviously it has no proprietary license so why does the additional driver gui label it as something its not?

I dont understand, All that does is confuse the end user.

The b43 legacy software was just for version 2 of your card. You have version 3 so the standard b43 is the correct version to use.

Also, the suggestions made by wildmanne39 which seemed to work for everyone else, didn't have any effect when I tried them. I'm ready to try anything. Thanks in advance

ok, so i installed ubuntu through windows just fine, but i cannot get my STA driver to work.

I went and got the tar to build the driver myself since its not easy for me to get to our houses ethernet connection (personal reasons of course.)

So i started to try and build the driver, but it said i was missing some build packages, so i went back to windows and searched and found that i could get the packages from a livecd.

I dont have a live cd,but i do have a live usb. tried booting up with the usb but could not find a place that said install packages to my current install.

So how do i get the packages from my usb onto my current install so that i can build the driver? Or, am i just doing this totally wrong (as in does the windows install come with the driver and im just overlooking it).

please and thank you for your responses.

To get the drivers from a LiveUSB you boot into the normal Desktop then plug the USB in. Open the file browser and look for the Usb stick in the left panel.

From there navigate to pool/main/b for the b43-fwcutter and build essential packages, double-click on the .deb files to install.

For the STA driver navigate to pool/restricted/b and install similar to the above.

Now assuming you have a b4311 chip the STA driver will not work on 11.04 and 11.10.

The first packages might be enough to get some funtionality for the wireless however the part that gives full wireless is not available on the CD or USB. The needed package is 'firmware-b43-installer. So to get that you will either have to plug a cable in or go to a different computer and download the attached file.

I am looking for the install instructions for the file and will post them later.

Found them here. http://ubuntuforums.org/showthread.php?t=1859446&page=4 post #34 has the instructions and post #40 has further instructions.

Well, now it will recognize the wireless if i enter through hidden networks, but it doesnt show the available networks, and the wireless wont connect (it keeps saying i am putting in the wrong password.)

What should i try to get this going right?

Heya All Just Thought I'd Let Ya Know How I Fixed My Wireless On Sony Laptop ](*,)
1.Download WICD wireless manager
2.Follow These Instructions

The issue occured after some suggested updates from the Ubuntu graphical update tool.
The wireless network to which it was connected was a WPA-PSK (WPA2) Passphrase authentication.
The network key was properly typed in and was working well on another system so the error Connection Failed: Bad Password made no sense.
There was nothing unusual in /var/log/wicd/wicd.log , that made me even more curious about what might be causing the error.After a lot of try outs and a lot of readings and tests I finally got the cause of the weird Bad Password errors produced by wicd
Weirdly enought, somehow the Ubuntu package update tool has installed the default gnome network-manager package.
The installed network-manager package has mismatched somehow the way wicd connects to wireless networks and as a cause the wpa_supplicant binary was not properly invoked.
As a consequence of the network-manager being present on the system the wpa_supplicant process which made the exact connection to the wireless network was not launching in, the exact wpa_supplicant invocation missing was:
wpa_supplicant -B -i wlan0 -c /var/lib/wicd/configurations/0022b0aa424a -D wext

Luckily the solution to the notebook wireless device unable to connect to the Wireless network was simple.
All I had to do is completely remove all occurance of network-manager packages installed on the Ubuntu system, by issuing the commands:
sudo apt-get remove --yes network-manager
sudo dpkg --purge network-manager-pptp-gnome network-manager-pptp network-manager

The reason for issuing the a dpkg –purge command was my desire to completely get rid of all kind of network-manager related configurations.


Now Just Go To WICD Put In Password For Wireless And Connect
Now after re-connecting with wicd wireless manager, it worked fine \\:D/
OMG Its Fixed
I Bet This Way Will Fix Problems With Other Linux Distro's Too And Other Wireless Cards
Seems There is a problem with network manager
Happy Holidays All:KS

I am running Kubuntu Natty on a Dell Latitude D610 laptop. My wireless card is the BCM4318. Using that information and this guide (https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx#Installing%20STA%20drivers) I decided that I should install the b43 drivers.

I ran both of these commands:



~$ sudo apt-get install b43-fwcutter

~$ sudo apt-get install b43-fwcutter firmware-b43-installerNothing is showing up in my Additional Drivers window, and I have tried restarting a few times hoping the new drivers would appear.

I tried installing firmware-b43-lpphy-installer through the KPackageKit, but it gives me this error message after installing about 80%.


One of the selected packages failed to install corectly.More information is available in the detailed report.

subprocess installed post-installation script returned error exit status 1I'm not sure what else to do. I have followed all of the guides.

edit: I tried looking on the Kubuntu forums to see if they might have something more relevant. All I found was this guide (http://www.computerandyou.net/2011/05/how-to-solve-no-wireless-networks-in-ubuntu-11-04/). I followed "Alternate Solution 2" and did the whole blacklist thing, but that didn't work either.

edit2: Well, my network manager seems to recognize that the driver is b43, so why can't I activate it?

edit3: If this is any help, I wasn't able to get wireless working during my live session of Kubuntu 11.04 either, so I don't think any of the solutions involving a live CD will work.

Hello! I hope someone can help me with this, because it's being very frustrating.

I bought a new netbook two days ago; a HP Pavilion dm1, and got my dual-boot all set up with Windows 7 on one side and Oneiric on the other. I had a lot of problems with Unity, so I reverted back to using the Classic Desktop - but that's not really the problem.

Ever since the fresh install (I installed and partitioned from a USB, since I have no disc drive), update manager has been popping up with 298 (or thereabouts) updates that need installing. Every attempt leads to a failure, with the message: failed to download package files, check your internet connection.

Now, my wireless indicator is telling me that I have signal, but it keeps dropping out on the internet too; I can access at times after restarting, then after a while it just drops out completely, but the indicator insists that I'm still connected. I am currently wired in but typing this on a different laptop, and it has the same issue with the updates, and now the internet has just dropped out as well.

I've been googling around for solutions, but none of them have worked. I tried changing the proxy settings and the connection settings, checking the updates before attempting an install (as in this (http://ubuntuforums.org/showthread.php?t=1772264) thread), and a few things with the drivers on terminal but to no avail.

I'm sort of at a loose end now, so I'd appreciate it if anyone could point me in the right direction?

You would definitely be better off starting a new thread with your issues. Not very many people look at this thread these days as it is so large.

There are some very clever users here and they are more likely to see a new thread.

Ah, thank you for that! I wasn't sure whether everything to do with this issue was meant to go in this thread or not.

I shall go make a new one directly! :D

why is this problem not resolved with patches? Why does thousands of people need to get to this forums and troubleshoot for hours ( for me it has probably taken days ). Why cant the ubuntu developers release a ******* working patch to fix this issue!!!

I had such problem with 11.04. But with XUbuntu 11.10, b43 drivers were installed properly by default.

@ alreadytaken4536

Thanks for the reminder.

Have looked at your lsmod and there are no drivers installed, so rechecked your earlier post about what you installed and found what might be the problem.

Run this in a terminal
sudo apt-get install firmware-b43-installer

Reboot and it should be working. If not repost a new
lsmod

Thank you.

Hi all,

I'm using Dell Inspiron 1545 with Ubuntu 11.10 and my wireless card is:

c:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)

I have no problem with installing and activating STA drivers; however, the signal level is always too weak in Ubuntu. Sometimes Ubuntu doesn't even detect the networks that I can connect in Windows 7 without any problem at all. Is there any way to increase the signal level, or is it just because the STA drivers are not as good as Windows drivers in Linux? If that's the case, is it possible to use ndiswrapper tool to install wireless drivers instead of STA?

Thanks.

Hello there,
Am a newbie and am using
Ubuntu 11.10 (Oneiric Ocelot) [Installed using wubi]

on an Asus 1015PN netbook with 2Gigs memory.
Got a Broadcom 4313 chipset [14e4:4727]


And now am in a real mess:confused:



I wanted to connect my netbook to my mobile using Joikuspot premium

and i was able to scan and find the wireless ap but not able to receive an ip so i set a static ip and disabled ipv6 , still no go. . .



Then after reading a post i installed the broadcom wireless source , common and the firmware using synaptic, after uninstalling the previous brcm sta driver

[which was downloaded form http://www.broadcom.com/support/802.11/linux_sta.php]



After rebooting the system i did a iwconfig and was [B]not able to find the wlan0 interface which was there before, so i removed the drivers that i installed and reinstalled the old broadcom sta from their site, am still not able to find the interface [but ubuntu recognizes my wlan card when i do a lspci]. ](*,)



Someone please help me. . . :sad:

update: guess its conflicting drivers , searching for the conflict now

Update: Solved it bcma was conflicting with wl driver, so blacklisted it. and even the wifi tethering problem was solved. now goanna setup a hotspot [like connectify] and a webdav server.

Check to see if ssb, bcma, wl or b43 is loaded:
# lsmod | grep "ssb\|wl\|b43\|bcma"

If any of these are installed, remove them:
# rmmod ssb
# rmmod bcma
# rmmod wl
After this you try to re install your STA driver. Check if it helps. The problem you might be having is the problem of conflicting drivers.

Hello,

I have added a broadcom wireless but am having issues with its install and working. Firstly I searched and came up with a few solutions but none have worked.

When I type lspci -vnn | grep 14e4 I get this:
02:02.0 Network controller [0280]: Broadcom Corporation BCM4306 802.11b/g Wireless LAN Controller [14e4:4320] (rev 03)

Installing the card in the network icon, the card needed a firmware upgrade. I having tried to downloaded the b43 and b43 legacy drivers at the command prompt but kept asking me to use the installer CD. Then I decided that this was a good time to upgrade to 11.10 of ubuntu. Then on the restart the wireless card is no longer seen in the network icon.

Have tried installing and re-installing both the b43 and b43 legacy drivers, each one at a time and then removing the drivers. This has been with the package manager. Now its still not seen so don't know what to do next.

Hope someone can help.

Have tried the things that mentioned in the 7 posts that mention this card i'm still at a loss.

Hi Folks

Your advice would be much appreciated as I am failing miserably to get a Broadcom bcw4306 PCI card to activate under Lubuntu 11.10. The system is recognizing the card as present but 'firmware not installed'. I have tried apt-get fwcutter and firmware-b43legacy-installer, but resolutely no activity (not sure if/how I need to activate these modules, as I'm a bit of a noob)

Many thanks

I seem to be having this problem with BCM4313 card. It's working fine whenever I'm right next to the router but when I want to use the computer elsewhere, in my room say, the connection gradually slows down and then grinds to a halt. I have to reload the connection and try to load the webpage as fast as possible. Sometimes the connection stays good for about two minutes before stopping again. I've tried most of the solutions given in this thread but they didn't help much. What else could I do with the driver in order to increase the range that it can actually use my network on?

I have a Broadcom 4311 on an old Dell 1521 Inspiron Laptop

lspci displays the following

0b:00.0 Network controller: Broadcom Corporation BCM4311 802.11b/g WLAN (rev 01)

I have not been able to successfully run the STA driver provided with any Ubuntu distribution since 10.04 Desktop LTS which if you are in any doubt it did work. I obtained a pre-release version of 12.04 due for release later this month and was not disappointed when again the Wireless STA driver failed to work.

The solution I came up with involved the editing of modules blacklist in etc and removing and installing some different drivers it is by no means ideal and I hope a resolution can be found for the Wireless STA driver can be incorporated as soon as possible.

First grep to locate the files with the entry Broadcom listed in the files

cat /etc/modprobe.d/* | grep 'bcm'

the problem with this grep is that it does not tell you the file to locate where the driver is listed so instead use this.

grep 'bcm' /etc/modprobe.d/*

Check your system and modify the above command to find the appropriate blacklist used by your system

Edit any files that show bcm43xx with a "#" in front of it and remove the hash so it looks like this:-

bcm43xx

All other modules variants listed can be left alone.

Then open a console and run the following commands

sudo apt-get remove bcmwl-kernel-source
sudo apt-get install firmware-b43-installer

As I say its not pretty but at least you can finally use the wireless on the laptop again from Desktop 10.10 to 12.04.

I have a Lenovo S10-3 Ideapad netbook, it comes with Broadcom BCM4313 wireless PCI card. After replacing the original Windows 7 Starter operating system with Ubuntu 10.04 Lucid (updated to kernel 2.6.32-40-generic), I lost all the wireless functionality. From Hardware Drivers I was able to install Broadcom STA wireless driver, but obviously it was not the right one:


These package contains Broadcom 802.11 Linux STA wireless driver for use with Broadcom's BCM4311-, BCM4312-, BCM4321-, and BCM4322-based hardware.Issuing lspci -vvnn | grep 14e4 command gave me this:



09:00.0 Network controller [0280]: Broadcom Corporation Device [14e4:4727] (rev 01)
Subsystem: Broadcom Corporation Device [14e4:0510]
While iwconfig command showed this:



lo no wireless extensions.

eth0 no wireless extensions.

eth1 IEEE 802.11 Access Point: Not-Associated
Link Quality:5 Signal level:0 Noise level:169
Rx invalid nwid:0 invalid crypt:2 invalid misc:0

vmnet1 no wireless extensions.

vmnet8 no wireless extensions.
Now my wireless works somehow but it was listed as eth1 device and performance is not satisfactory.

The weird thing is, when I boot up my netbook using Ubuntu 10.10 Oneiric from a USB stick, the installer could correctly identify my Broadcom card model and install the corresponding drivers. Even the BackTrack 5r2 USB installer can do the same thing and I was able to put my wireless card into monitoring mode using airmon-ng.

Now my question is: can I use the drivers from 11.10 version on my 10.04 OS? If so, how?

My conclusion is this is really a kernel problem and the only solution for me is do an OS upgrade. With Ubuntu 12.04 LTS just around the corner, I would rather wait for a little longer before I make this decision.

I have an Acer aspire one 722 with BCM4313 and had a lot of problems; i tried various distributions without success. The only one which works without any tweaking is ubuntu 12.04 beta

I have no problems so far with the 12.04 beta; everything works (did not test the mike.) However I do regularly :

sudo apt-get update
sudo apt-get dist-upgrade

So get all the improvments until the final versions

Thanks mauleshjani for the reminder...I tried Ubuntu 12.04 LTS on a USB stick. Installed the recommended wireless driver update,using a hardwire & found no connection to my router. I checked my subscribed threads & located your B43xx fix, the same fix that I had to run to get my Dell D620, w/Broadcom B4311 wireless to connect using Ubuntu 10.04 LTS over a year ago. We need to alert the current 12.04 LTS installers that the 12.04 LTS furnished wireless Broadcom STA driver install still does not solve the Broadcom B43xx problems. "G"

Hey all, I'm also trying to get a Broadcom BCM4311 wireless card working. I've just tried this and it has worked for me unfortunately. I'm on a Dell Latitude D630 if that makes a difference. Any help is greatly appreciated.

edit: looking at my wireless card through terminal it says "BCM4311 802.11a/b/g [14e4:4312] (rev 01)" hopefully that helps.

edit 2: Just got the wireless working. I ended not using bcmwl-kernel-source and instead used firmware-b43-installer along with b43-fwcutter. Btw, this is all on a fresh install of Kubuntu 12.04 LTS.

Hello,

I've just put a fresh install of 12.04 32bit on my friends acer 4620Z and cannot for the life of me get the wireless card to show up.

I've tried multiple walk throughs and guides from many sites, but none of them outline the process to install the drivers for 12.04. I just attempted soulG77's solution for 12.04, and that didnt work for me either.

Also, I am unable to use NDISwrapper, I'm able to download it in the software center, but when I attempt to install the .inf file, I get an error saying the NDISwrapper module is not found?

I did an entire reinstall and attempted just to install synaptic and ndiswrapper to use windows drivers, but I got the same error again. I'd appreciate any assitance any of you could provide. My friend needs her laptop as she is leaving for China in a week and wants to use it as a video phone to call back home. It would be awesome if any of you could help me figure this out!

Here is my sudo lspci -v

*******************SOLVED********************

After mucking around a bit more I figured out the fix for this on a fresh install of 12.04 is pretty simple.

If the additional drivers auto loaded the STA wireless driver, you can remove them in terminal with

sudo apt-get purge bcmwl-kernel-source broadcom-sta-common broadcom-sta-source

then run:

sudo apt-get install firmware-b43-installer b43-fwcutter

You should see your wireless access points when you reboot.

I did a fresh install of 12.04 Precise on my Lenovo S10-3 Ideapad netbook, even without using the Additional Drivers, it correctly detected my Broadcom BCM 4313 wireless NIC. The weird thing is, after installing Broadcom STA wireless driver, my wireless interface was changed to eth1 instead of the original wlan0. I can change the wireless NIC settings using nm-applet when it is eth0. But if I unstalled the STA driver, the wireless NIC will revert back to wlan0, although it could connect to various APs, I could not change its settings whatsoever. Any idea?

I have a Broadcom B4318 wireless card, and while I can get Ubuntu to boot from live media by blacklisting the wireless card, I'm wondering if it's possible to install the proper drivers (manually, I don't feel like dragging my desktop into my living room to get to an Ethernet connection) after blacklisting the card in GRUB, and whether or not (if the drivers can indeed install while the card required is blacklisted) simply deblacklisting my card after install would let it work. This issue is literally the one major roadblock keeping me from wiping Windows 7 from my computer. ;)

This worked for me as well. Broadcom 4312. However, I had to install the firmware-b43-lpinstaller instead, as I am running it on a lower powered netbook.

Also had to run updates twice, as it needed the latest kernel.

Did a full reinstall of Precise on my Compaq Presario M2000, which has a Broadcom 4318 wireless device, and used the alternate distro as the regular distro was hanging on me.

Referring to post #514 in this thread, which I posted last fall, I performed steps 0, 3, and 4. And it is working again.


Summarizing my install experience on a Dell Latitude D630 running Oneiric and the built-in Broadcom 4311 wireless device:

0) Connect to a network via a wired connection. :)
1) Installed firmware-b43-lpphy-installer via sudo apt-get install. Got some type of "installation failed; device not found" error message.
2) Ran update-manager, which populated the software center.
3) Removed firmware-b43-lpphy-installer and installed firmware-b43-installer via the software center.
4) Commented out the blacklist b43xx line in /etc/modprobe.d/blacklist.conf.

Ok, i have tried just about every guide i can find to getting wireless working on my DELL 1525...but im about ready to give up and by a USB dongle.

I have tried reinstalling ubuntu, b43 drivers, sta drivers...and any thing else i have read.

I am not a TOTAL linux noob, but i do struggle with even some of the simplest tasks as it has been about 5 years since my first (positive) experience with linux

I am willing to run any command and post outputs, but i need the commands pretty much spoon fed. i can google stuff like how to untar and other thigns like that if necessary, but the simpler the better.

Simple rmmod e1000e resolves the connection issue. What is intriguing I am unable to successfully blacklist this module co I have to manually remove it after boot. Does anyone have suggestions how to make permanent fix of forward this bug upstream to dev teams ?

mine just went dead on me after the latest update today. no matter what package i install, my wireless driver refuses to activate. if i try to use the additional drivers program, it tells me that it failed to install and to check "/var/log/jockey.log", which reads as this

This helped to me after upgrade from Kubuntu 11.10 to 12.04:



sudo apt-get update
sudo apt-get install firmware-b43-installer
sudo apt-get remove bcmwl-kernel-sourcethen reboot. LED on the keyboard is still orange, but the controller works fine.

HP ProBook 4525s, Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01)

Thanks a lot!

This worked for me. Dell Vostro 1500, NIC: Broadcom BCM4311 802.11a/b/g
Thanks, Jark!

Have you tried manually adding the line "rmmod e1000e" inside /etc/modules?


sudo gedit /etc/modules

and in the end of the file add the line

rmmod e1000e

Save, exit and reboot to test.

I'm a total noob...just built a system running Mythbuntu 12.04 with an old Buffalo WLI2-PCI-G54S wireless card. Its the Broadcomm 4306 rev 3 chipset. I tried to use the b43 firmware and didn't get it working, so then I tried the ndiswrapper method. I learned that ndiswrapper won't work on my 64-bit architecture, because Buffalo's Windows 98/XP/2000 drivers are 32-bit. I was unsuccessful in my attempt to use some Vista 64-bit drivers.

To undo my ndiswrapper attempt, I removed the ndiswrapper packages I'd installed, and removed b43, b43legacy, and ssb from blacklist.conf.

I then installed b43-fwcutter and firmware-b43-installer. My wireless card showed UNCLAIMED using lshw -C network. Using "sudo modprobe b43", my wireless card was recognized, and the GUI network settings allowed me to find and connect to my network with WPA2/AES and a hidden SSID. An additional driver was NOT loaded. I made the fix permanent by adding b43 to /etc/modules.

CONCLUSION: I *think* the following (from a clean install) would have made everything work without the 10 hours of pain I invested:

sudo apt-get install b43-fwcutter firmware-b43-installer
sudo modprobe b43
If it works at this point, then type

echo "b43" >> /etc/modules
This forum was instrumental in my education...hopefully this helps someone else.

I had wireless working fine on a clean install of 11.10. When I upgraded to 12.04, wireless stopped working. This is my wireless card:



lspci -vvnn | grep 14
0c:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)
I've tried several of the solutions proposed on this thread and none of them have worked yet, including installing firmware-b43-installer and b43-fwcutter, commenting out the "blacklist bcm43xx" line in /etc/modprobe.d/blacklist.conf, and adding a "b43" line to /etc/modules. Several times when I tried to activate the driver from the "Additional Drivers" panel, I got error messages in jockey.log about the device being blacklisted. The last time I tried it it appeared to work; it said I just needed to reboot to finish activating it. But... even after reboot, I can't get a wireless connection. Clicking on the networking icon shows: "Wireless networks / device not ready (firmware missing)". When I go back to the "Additional Drivers" panel it says of the Broadcom STA driver that "This driver is activated but not currently in use".

Any ideas?

When I go back to the "Additional Drivers" panel it says of the Broadcom STA driver that "This driver is activated but not currently in use".

When I search for "driver is activated but not currently in use", I find a lot of threads relating to a problem with the Nvidia graphics card driver, but nothing relating to a wireless card driver. Most of the advice about testing and fixing the problem with the graphics card driver seems very graphics-specific, but one site recommended doing "lsmod | grep nvidia". I did this instead:



jim@waylock:~/tmp/q2$ lsmod | grep b43
b43 342643 0
mac80211 436455 1 b43
cfg80211 178679 2 b43,mac80211
bcma 25651 1 b43
ssb 50691 1 b43
It looks like b43 is running, but not being used by any other processes. b43 is in turn using several other modules.

This finally fixed the problem:



sudo apt-get remove --purge firmware-b43-installer
sudo apt-get install firmware-b43-lpphy-installer


Immediately after the second command above finished, I got my wireless connection back -- I didn't have to tinker with the config files any more or the Additional Drivers panel.

After stuggling for years trying to find and install Linux drivers for my Broadcom B43-based WiFi card (branded as Microsoft MN720), I spend less than ten bucks and bought an Edimax WiFi dongle for my laptop. It installed in a snap and works great. My connection speeds are usually 8 to 10 times faster than I ever got with the Broadcom. If you are still battling with the Broadcom, take my advice: buy one of these thumbnail sized WiFi dongles (available in various brands for less than $10 and plugs into USB port), and put the Broadcom where it belongs: in the trash.

I installed Pangolin on my wife's laptop last night after her Windows install bit the dust. Couldn't get the wireless working; it gave a "firmware not installed" message.

I put the laptop on the hardline, and came here looking for help. Installing the STA driver as noted in this thread fixed it.

Just wanted to say thanks for a useful and helpful thread.

Problem in Precise Pangolin 12.04 with the Broadband 43xx Wireless Card: Unable to download firmware for wireless. (Also works for 11.10, 11.04, 10.10 and 10.04)

From the 'Additional Drivers' section:

Possible Solutions:

Solution 1: After installing with the alternate cd, I needed a cable and after updating, I was able to download the STA driver through the 'Additional Drivers' section.

Solution 2: Another option is here (https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx#Installing%20STA%20drivers).

Solution 3: System > Administration > Synaptic Package Manager > Search: firmware-b43-lpphy-installer > Click Mark > Click install > Close (This has been removed starting with 11.10 - Oneiric Ocelot. It may be installed with the Ubuntu Software Manager.)

Kontza found the solution (https://bugs.launchpad.net/ubuntu/+source/b43-fwcutter/+bug/651010) (post #3), so thank him for it.

This solution fixed this problem on my Dell Inspiron 1545 with a Broadcom 4312 card. (Card Tech Specs: 0c:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01))
I have one of those antennas on the back of my emachine pc but don't use it, read about the driver and where to download it. My location gets bad reception so wifi might be issue for me, I might go usb modem or wifi hotspot which is brodcast in the house it will pick it up cuase it is close.

Please help.

I have Dell Dimension E521 with USRobotics5417 card (BCM4218 chipset) for networking. In the past (up to Ubuntu 11.X) I was able to install proprietary USR driver with ndiswrapper, and it worked. Just spent about 3 hours trying to get it to work on 12.04, and no luck. If you do not have suggestions on how to get this to work, which network card would you recommend to replace USR. I have N-Class Linksys E3200 router. The card should preferably have external antenna.

I have a Dell D800, loaded Xubuntu 12.4, and all looked good except no wireless. I struggled several weeks. Today I happened upon this page in the forum. I downloaded the zip, followed the instructions and I am looking at the laptop with wifi working!

The wifi chipset on my D800 is BCM4309.

The forum page with my solution is:

You want to look at post #11 from Wild Man.

I hope this solves your problems, it was driving me batty too!!!

Nate33, give this a try....


This is what worked for me:
I followed MrD's suggestions and had to tweak it a little:
1) attach ethernet lead
2) in "additional drivers", turn off STA driver that was auto installed after vanilla 11.04 install
3) in synaptic package manager, remove bcmwl-kernel-source, every b43/broadcom entry, finding them by using the "search" button on those two terms and not the "quick filter"
4) restart computer
5) open terminal,"sudo apt-get install bcmwl-kernel-source"
6) restart computer and enjoy the wifi.
(at this point I did not have wifi going so then I continued on)
7) in synaptic package manager I searched (again search, not quick filter) for broadcom and installed the following: b43-fwcutter, broadcom-sta-common, broadcom-sta-source. Already installed was bcmwl-kernal-source, so I left that alone.
restart, yes again. I was still connected to ethernet but I hovered over my ethernet and opened the list of availalble networks and could see my wifi, so I disconnected the ethernet and connected to wifi.

I have to agree about this annoying wifi card. I freaking Linux now but each time I have a problem with Ubuntu it is always surround my wifi.

I just last night did a sizeable update of over 200 files on 12.04 and again I've lost the wifi. Unfortunately enough of a gap passes that I can't recall what I did that fixed it last time.

I may have to do my own thread but hopefully within this 61 pages (sigh) there contains the bounty of an answer to my particular problem.

When I run
lspci -nn | grep 0280
lsmod | grep -e b43 -e wl
I get the following:


05:00.0 Network controller [0280]: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller [14e4:4727] (rev 01)
So NOTHING on the wl module at all.

I then tried blacklisting all the 80211 and wl module in blacklist.conf and then loading the wl module and it's dependencies with
sudo modprobe lib80211
sudo modprobe lib80211_crypt_tkip
sudo modprobe wl which then gave the following error


FATAL: Module not found

The search it doth continue..


EDIT: Success with STEP 2 from the original post. All I did was removed the Broadcom bcmwl-kernel-source package (using the Ubuntu Software Centre and the restricted repository), rebooted then installed it again (couldn't find even broadcom in the package search so I just pasted in bcmwl-kernel-source again and I was good to go).

BOOM!! Result. Get in!!

Hi you need the Broadcom STA Driver. Plug in a cable please and in a terminal run
ksudo apt-get install bcmwl-kernel-source wait a few seconds for networks to be found.

If none found also run
ksudo modprobe wl and wait again. If after this still no networks found reboot the system.

All should now be working for you.

I upgraded to 11.10 from 11.04 and my wireless stopped working.
STA drivers were installed and were activated (By default )
I have Dell Inspiron 640m and network card is Broadcom 4311.
I did following and it worked for me.

From Ubuntu software center

1. Remove bcmwl-kernel-source.
2. Check if firmware b43-installer and b43-fwcutter are installed. Install it if not installed.
3. Restart the computer.

Same thing happened when I upgraded to 11.04 and everytime during package upgrades if I upgrade wireless drivers it would stop working.

Hope this helps.

raghavsetu you are DA MAN!

I fought with slow wireless in Ubuntu 12.04 with a BCM4322 for months! I tried everything; disabled ipv6, iwlwifi 11ndisable=1, rfkill unblock all, iwconfig eth2 power off, and every other hack that can be found by googling 'ubuntu wireless slow'. Your suggestion finally fixed this problem after I wasted more than 10 hours.

Not only that, my download speed went from ~1 Mbps to over 16 Mbps! Now my Ubuntu machine is finally as fast as my Windows machines!

anyone have issue see their 5Ghz network? I have bcm4322 on HP TochSmart tx2, and I successfully installed the STA driver. And with iwlist I can see it support 5Ghz channels. But I can't see my 5Ghz network from router using network-manager.

Does anyone have same issue? or solution? It was working fine in ubuntu 10.10 to work with 5Ghz.

My bad, just realised my router's wifi channel was set to something not listed in the supported range. Now changed it to 44, the 5Ghz network showing in my network list. Yes!!!

Hi,

I recently updated my 11 year old daughter's laptop (a hand-me-down Dell Inspiron 1501 she uses to help with her schoolwork) from lubuntu 12.04 to lubuntu 12.10.

Everything seemed to go OK except wifi no longer works.

Previously, I believe I needed to blacklist the ssb and b44 drivers and to enable the b43 driver, to match her wifi-only usage pattern. I recall seeing a post somewhere that said there was some sort of incompatibility between the b43 and (ssb+b44) combination - they should not be loaded in the same session. In any case, it worked in lubuntu 12.04 :)

After the lubuntu upgrade, there seems to be a link now between b43 and ssb. See example session below, where you can see that there is a new ssb_hcd driver that seems to be needed for b43, but it also brings the full ssb along too :(


$ lsmod | grep ssb
ssb_hcd 12749 0
ssb 50087 1 ssb_hcd

$ sudo modprobe -r ssb_hcd

$ lsmod | grep ssb

$ sudo modprobe b43

$ lsmod | grep ssb
ssb_hcd 12749 0
ssb 50087 2 ssb_hcd,b43

$ sudo modprobe -r b43
$ lsmod | grep ssb
ssb_hcd 12749 0
ssb 50087 1 ssb_hcd

$ sudo modprobe -r ssb_hcd
$ sudo modprobe -r ssb
$ sudo modprobe b43

$ lsmod | grep ssb
ssb_hcd 12749 0
ssb 50087 2 ssb_hcd,b43


Here is the output of sudo lsh -C network (with b43 and b44 enabled)

Note that the last

Interestingly, the last block has a serial that looks like a MAC address (of the Broadcom BCM4311 card?), the first one does not. Perhaps some combination of these blocks would be enough to get it working, but I've had no success so far with this.

I have noticed the wifi indicator light on the laptop case flash on briefly (< 1 second) when the laptop boots up.

I should mention the laptop has an F2 hotkey, which in its past Windows XP life, caused wifi to toggle on/off, but lubuntu does not seem to recognise it.

If I could get it to boot with wifi enabled, that would be great. As administrator, I am happy to enable a wired connection if necessary, but for obvious reasons I would prefer not to give extra privileges (e.g., to run modprobe) to my daughter.

I would be very grateful for any advice on how to resolve the issue- I have spent several fruitless hours trying various 'fixes' suggested in this and other forums :confused:

Before either of us get too excited, I have not yet upgraded from Precise and have a different network card. That said, here is a bit of (somewhat) useful information that I've found so far today.

Impatient Executive version:
Try installing the Broadcom-STA driver (wl) via these instructions:

<a href="http://wiki.debian.org/wl"> Debian Wiki on WiFi using Broadcom driver </a>

OK, let's hope you're not too impatient just in case I'm wrong about the above.

More Detailed version:

Reference 1:
<a href="https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx#Installing%20STA%20drivers"> Reference 1 </a>
Reference 2:
<a href="https://bugs.launchpad.net/ubuntu/+source/b43-fwcutter/+bug/651010"> Reference 2 </a>

According to the Ubuntu Docs (Reference 1) you (BCM4311) and I (BCM4312) should be using the 'wl' driver which *does* instruct the blacklisting of ssb and others, as I recall. I say this because I'm currently using a different driver but I've used the 'wl' (broadcom-sta) driver in the past with great success. But somewhere I got steered away from it on this card because it is one of the 'low power' cards.

Care to share your lspci information? Here's mine:


$ lspci -vvnn|grep 14e4
yields:

0b:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)


For me, the "LP-PHY" means (from some source) that I should use the following (from dpkg):
b43-fwcutter install
firmware-b43-lpphy-installer install

This is in agreement with what I found earlier in the thread (actually, the original post):
"Had the same problem, then I noticed that instead of firmware-b43-installer I had to install (manually, via synaptic) firmware-b43-lpphy-installer." --Kontza in LaunchPad.

<a href="https://bugs.launchpad.net/ubuntu/+source/b43-fwcutter/+bug/651010" Ref 2 </a> (Reference 2)

But also see (again, from the original post):

<a href="https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx#Installing%20STA%20drivers" Ref 1 </a> (Reference 1)

I think our situations are sufficiently different that what I'm currently using is not your solution despite Mr. Konza's expert advice (which applies to me). I am much more familiar with the Debian advice as that is what I've used in the past for some really old hardware using a PCMCIA wifi card (Linksys, I think, but a Broadcom chipset nonetheless).

Care to share what you've tried that hasn't worked?

General comment: This thread started over two years ago. 62 pages is quite a lot and I won't read all of them unless I'm stuck on an elevator and the rest of the Internet is down. :^)

Thanks @HunkirDowne!

I will take a look again at those references and will report back.

I did look at them before (when I installed 12.04) but I think I reverted to the b43 driver at the time (can't remember the reason why...).

However, it is possible that the Broadcom wl driver would work with 12.10 - definitely worth a try :)

Thank you.

Unfortunately, the problem is still there...

Firstly, here is the output of lspci, as requested by @HunkirDowne:


$ sudo lspci -vvnn | grep 14e4
05:00.0 Network controller [0280]: Broadcom Corporation BCM4311 802.11b/g WLAN [14e4:4311] (rev 01)
08:00.0 Ethernet controller [0200]: Broadcom Corporation BCM4401-B0 100Base-TX [14e4:170c] (rev 02)


As you can see, there is no reference to LPPHY (so I did not follow the rest of @HunkirDowne's suggestions).

I followed the advice in one of the suggested references

https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx#Installing%20STA%20drivers
in particular the "STA - Internet Access" > "11.10 (Oneiric Ocelot) - 12.10 (Quantal Quetzal)".

Because b44 depends on ssb, I needed to add that to the modprobe -r line.

When wl is enabled, it seems to bring in ssb and b44 :(


$ sudo modprobe -r b43 b44 ssb wl
$ sudo lsmod | grep ssb
$ sudo modprobe wl
$ sudo lsmod | grep ssb
ssb 50087 1 b44


I found the webpage that suggested that the ssb driver is not compatible with wl:


http://www.broadcom.com/docs/linux_sta/README.txt

On that page, there is a section "Remove any other drivers for the Broadcom wireless device." which mentions b43, ssb, etc. The recommended approach is to rmmod the incompatible drivers. I tried this, ran modprobe wl again and, you guessed it, they were back in the list of modules returned by lsmod!

The other thing I tried was to add the problematic drivers (b43 b44 ssb, etc) to /etc/modprobe.d/blacklist.conf and rebooted. Again, the b44, ssb and wl modules were loaded.

Then I thought that maybe there is an explicit reload of these modules that happens after processing the blacklist file. I checked /etc/modules and the only uncommented line was

lp

which I assume enables printing, but seems to be "safe".

At the moment, I am beginning to suspect there is a bug somewhere in the wifi setup in 12.10 - it probably does not help that both cards are Broadcom and may share driver features. I would have given up long ago if I did not know that wifi was working in 12.04 and I am reasonably certain that the "fix" involved 'disabling' b44 and ssb.

Lastly, if it helps understanding, to access the internet when both Broadcom cards are inoperable, I use a tethered 3G connection (to check advice pages), but that's not a practical solution in the long term given the intended use of the laptop.


Thanks @HunkirDowne!

I have got the same problem with 12.10.
To note : during installation of 12.10, and for some time after installation, Wifi worked nicely. It seems to me that it stopped working after a kernel update (3.5.0-18, a second update 3.5.0-19 did not improve anything wrt this problem).

If you have a b44 ethernet card then you have these lines in /etc/modprobe.d/blacklist-bcm43.conf



blacklist b44
install wl modprobe -r b43 b44 b43legacy ssb; modprobe --ignore-install wl $CMDLINE_OPTS; modprobe --ignore-install b44


So when you modprobe wl, it automatically modprobes b44 too. Play around with this line and see if removing the "modprobe --ignore-install b44" fixes the problem. If it does then you need to raise a bug.

P.S. It is easy to miss new posts in sticky threads and this is why they sometimes don't get replies. It is much better to create a new thread with your problem. Then people with the same problem can easily find it, rather than wading through a 63 page thread (and if you want to be super helpful, update the community wiki page!).

Have thought about starting a new one when the next distro comes out, but had not thought about cutting it and starting with a new one. That is a good idea. Thank you for the suggestion, Simm2. Done.
