Good morning everyone!

I am having a problem with my wifi in my computer, first let me describe what kind of computer I have:

DELL Inspiron 1501
Broadcom BCM4311 is the wifi adapter

The problem I am having is that I cannot get to search for wifi networks. It looks like the driver and everything is there but the wifi is disabled for some reason.

I installed the drivers provided by the "Additional Drivers" application and they do not work.

I also followed this fix and I could see in the menu that the wifi was added but I was not able to click it or look for wifi's http://ubuntuforums.org/showthread.php?t=1730670

Are there any other fixes I can try? Thanks in advance, CHeers!!

Oh! I forgot to say, I have Linux Ubuntu 11.04 - the Natty Narwhal

A Dell you say? Hmmm...

Let's run some diagnostics and see where you are so far. Please open Applications > Terminal and run and post these two commands:
dmesg | grep b43
rfkill list allThe pipe symbol | is on the right side of my US keyboard on the same key with \. Thanks.

Does your Dell have a wireless switch or key? Does it work as expected?

Yes sir I am using a DELL Inspiron 1501

After running those commands you provided this is my input:



emkill@emkill-Inspiron-1501:~$ dmesg | grep b43
[ 120.548844] b43-pci-bridge 0000:05:00.0: setting latency timer to 64
emkill@emkill-Inspiron-1501:~$ rfkill list all
0: dell-wifi: Wireless LAN
Soft blocked: no
Hard blocked: yes
emkill@emkill-Inspiron-1501:~$


The only way to turn on and off the wifi is by pressing the following keys in my keyboard: Fn + F2

Hard blocked: yes implies that the wireless switch has the wireless turned off. Is that true? Does the light go on and off as you manipulate the switch? Is the module dell-laptop loaded?
lsmod | grep dellDoes your wireless spring to life if you remove it?
sudo rmmod -f dell-laptop

just try this commonds in terminal

sudo ifconfig wlan0 up

ERROR: Removing 'dell_laptop': No such file or directoryOne wonders why it can find no such module when we can see it clearly before us! Let's try an easily reversible experiment. Please carefully do:
sudo su
echo "blacklist dell_laptop" >> /etc/modprobe.d/blacklist.conf
exitReboot and try again:
rfkill list allThen press Fn+F2 and run again:
rfkill list allAre you able to achieve hard blocked : no?

Next, we will address the driver.

One wonders why it can find no such module when we can see it clearly before us! Let's try an easily reversible experiment. Please carefully do:
sudo su
echo "blacklist dell_laptop" >> /etc/modprobe.d/blacklist.conf
exitReboot and try again:
rfkill list allThen press Fn+F2 and run again:
rfkill list allAre you able to achieve hard blocked : no?

Next, we will address the driver.

I did that exactly how you asked me to do it, but nothing happens.

Ubuntu recognizes your wireless card, but Network Manager does not.
Type this into a Terminal window:

sudo apt-get install b43-fwcutter
sudo modprobe wl
sudo modprobe ssb

Then could you give me the output of these commands:

sudo /etc/init.d/networking restart
nm-tool

Now reboot.
Then, could you still give me the output of:

nm-tool

The reason why I'm telling you to always run it, is because we want your wireless card to show up under Network Manager.

For some reason my ethernet stopped working so I am reinstalling Ubuntu again.

____________

After reinstalling:

When I pull the networks menu, there are new choices and looks like this:

Wired Network (grey non clickable)
disconnected (grey non clickable)
___________________
Auto eth0
___________________
Wireless Networks (grey non clickable)
device not ready (firmware missing) (grey non clickable)
___________________
VPN Connections >

Also:

After doing the nm-tool command, the device is listed in terminal as follows:

- Device: wlan0 -----------------------------------------------------------------------
Type: 802.11 WiFi
Driver: b43
State: unavailable
Default: no
HW Address: 00:0E:A6:F1:4B:9C

If you have an ethernet connection, please do:
sudo apt-get install firmware-b43-installerReboot and you should be all set.

So I want to make a summary for future reference for DELL Inspiron 1501 Users that have installed Ubuntu 11.04 - the Natty Narwhal, the WiFi will only work if you install Ubuntu as follows.

When you boot from CD, do not attempt to try ubuntu, install it right away, at any point do not try to use your wifi.

When installation is done, 100% of the times, your ethernet port will get internet so the first thing you are going to do is open Synaptic Package Manager (Found in System > Administration > Synaptic Package Manager) Search for "b43" and select the second option and mark for installation (by doing right click on it) when you are done installing you will be able to see WiFi and your wifi will start working.

Note: if you have been messing with your wifi card by applying other fixes than this, it is better to do it with a fresh installation. For some reason this fix will not work if you have been already messing up with your wifi drivers.

Special thanks to the people who put their valuable time in helping me to resolve this problem, thanks thanks cheers cheers!!!

Do you have a working internet connection? apt-get needs to reach the Ubuntu repositories and others.

Please open System > Administration > Synaptic and select Settings > Repositories. Be sure that Restricted and Multiverse are selected. Press Reload and search for b43. Is your package there? Can you install it?
