Hi I've spent hours trying all the suggestions listed on Forums on this problem all over the Internet and I still can't get my wireless working. It's very discouraging because it might force me to go back to Windows which I hate. Can someone help?

Perhaps I can give you some information to help identify what the issue is? b43 isn't coming up in my list of drivers...just Broadcom STA which doesn't work.

I think I've removed all the blacklisted stuff.

Did you find any suggestions to install drivers from source? Sometimes using the source fixes it. – RolandiXor Nov 18 '11 at 4:26
thanks for your reply! I don't know if I know how to do that. I've installed the b43 several times from terminal: – Annie Nov 18 '11 at 5:50

This page has been very useful but I still haven't got the b43 working: – Annie Nov 18 '11 at 5:51

I had the same problem here! This is the fix that I used to great success:

Ubuntu 11.10 getting wireless BCM4311 working

The basics are this:

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

The article will give you more background on the issue.

I used a similar method to fix a friend's wireless before but could not remember the steps. I can confirm also that this works. – RolandiXor Nov 18 '11 at 5:07
I finally got it to work! There were some blacklists on the bcm43xx in some hidden files that I think were responsible...but I'm not really sure. But it's finally working. Many thanks to you both for your help! – Annie Nov 18 '11 at 6:13

Just thought I'd let you know: I spent hours trying to get wireless working on my parents' machine. Finally, I found this post, and it solved my problem. Thanks! – Scott Severance Jan 12 '12 at 4:25

There is also a community documentation on Broadcom BCM43xx PCI based wireless network card for Ubuntu 10.04 & onwards.

There are methods for installing the drivers even without the Internet access.

If you don't have Ubuntu CD/USB, download four latest packages (dkms, patch, fakeroot, bcmwl) from





Put the .deb files together in a folder, and install by typing this command in Terminal

sudo dpkg -i *.deb

Sorry about my bad English.
