View Full Version : [SOLVED] More wireless networking woes (broadcom & 11.04)

August 23rd, 2011, 04:41 AM
Hello I made the mistake of creating a new user account and deleting the old one in Ubuntu. Now I can't connect to my wireless network. I think that I have the correct drivers installed, but I am unable to see (discover?) wireless networks and don't even have any wireless options in the upper right corner. I am pretty frustrated with this.

Let me tell you what I know. Please help if you can, or at least point me in the right direction.

Laptop: Dell Inspiron 1721
Ubuntu 11.04
Network Controller: Broadcom BCM4311 802.11b/g WLAN

How do I set up the ability to see wireless networks?
Is there a way to verify that I have the correct network device drivers installed?

I am a non-experienced linux user, so you will probably have to be specific with descriptions and assume I don't know how to do things.

Thanks for your help.

-Eric

If no applet try this, if just all greyed out install proper drivers. Install with wired and then remove wire and reboot.

nm-appletDoes it pop up in right hand corner.

#Open Synaptics and check by typing in "bcm" without quotes and check
on driver situation installed. The two marked should be installed click on screenshot.
remove any other bcm installed just want those two.

Hi welcome.. Oops you got it garvinrick4

Open a terminal Ctrl-Alt-t

Copy and paste the following in the terminal


lspci -nn | grep 0280
lsmod
sudo lshw -C networkCopy the results and we will have some place to start.

sudo apt-get install b43-fwcutter


sudo apt-get install firmware-b43-installer

Those are the wireless driver and firmware I would recommend.

You might have a common problem to do with proprietary drivers and/or the card being blacklisted


- open the 'Synaptic Package Manager' and search for 'bcm' and uninstall the 'bcm-kernel-source' package


- make sure the 'firmware-b43-installer' and the 'b43-fwcutter' packages are installed, installing should take care of configuring your device



Open a terminal up and type:- "cat /etc/modprobe.d/* | grep bcm" ... to see if bcm43xx is blacklisted,

... if it is, type "cd /etc/modprobe.d/"
... and in there type "sudo gedit blacklist.conf"

... put a hash "#" in front of the line: blacklist bcm43xx

... save the file and reboot and hopefully your sorted unless you need to make changes to suit your particular setup which you can do from Connections or Network Manager


---edited---

Whooops, did not see that you were in good hands, my bad, gl (y)

epwolfram
August 23rd, 2011, 05:33 AM
Does this mean it IS blacklisted?

blacklist bcm43xx
blacklist bcm43xx

nm_geo, I think I have the b43 firmware installed.

-Eric

You have STA (wl) wireless driver installed and that causes blacklist issues with b43 & ssb. Since your ethernet driver is b44 you must have the ssb module to make it operate properly.

When you try to install the STA (wl) it creates a file that blacklists b43 & ssb. For some reason the ssb module can work around the blacklist but b43 can not. So you need to de-activate/remove the STA (wl) driver and comment out the blacklist of b43 and ssb.

Then make sure you have b43-fwcutter and firmware-b43-installer installed..

This link should help read message 51 through resolution.
