Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I have tried doing all the research and trial and error that I could on my own but with no avail.

So can anyone out there help me? I cannot get my Broadcom b43 wireless adapter to register with Ubuntu. I even tried the steps here, but with no luck. So if someone can help me or at least point me in the right direction I would be grateful.

The Broadcom STA driver wl is incorrect for your device. Please get a temporary ethernet connection and do:

sudo apt-get remove --purge bcmwl-kernel-source
sudo apt-get install linux-firmware-nonfree

Reboot, detach the ethernet and your wireless should be working.

I cannot thank you enough. So simple too. But yeah thanks again, you really helped me out. Now I just realized my headphones work but I have no speaker sound. I just downloaded alsamixer and checked my levels and they were good. Do you have any advice for this problem? –  Skateguy May 22 '13 at 12:45
    
That's another question which I suggest you post. Will you please accept my answer? –  chili555 May 22 '13 at 12:56
    
yes, thank you. –  Skateguy May 22 '13 at 12:58
