So I followed the instructions here http://ubuntuforums.org/showthread.php?t=1974006 about how to solve this issue. It worked for a bit and then stopped. After doing a modprobe I could at least see my network and click on it but it would not connect (I can always see it if I look under the listed wireless networks under VPN Connections, however). I'm thinking, from what I read at least, the issue might be that my wireless switch was on during those first steps. Do I now have to undo the b43 install and do it again? Or is there something else I could try? I just made the switch to Linux yesterday, so I am hesitant at this point to mess with anything on my own. I should note now that it was installed by someone who knows what they are doing, so we are all good on that front.

I try that solution and it's working.
You need to download the B43.zip install, unzip it into a folder named b43, move the folder in /lib/firmware
and do a mobprobe
sudo mobprobe b43

Welcome to Ask Ubuntu! Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference.– fossfreedom ♦Dec 1, 2012 at 10:20
lspci | grep Broadcom
from the terminal, if you don't already know. Any additional info might help.lspci -nnk | grep -iA2 net
,lsmod
. Please do not post outputs in the comments section. If you can't edit the question, use pastebin.com, and post a link. It probably also wouldn't hurt getting the firmware from a more reliable source. Try following this howto: help.ubuntu.com/community/WifiDocs/Driver/bcm43xx.sudo rm -r /lib/firmware/b43
, then hook up with a wired connection and install withsudo apt-get install b43-fwcutter firmware-b43-installer
. That basically installs the firmware you tried and sets up everything automatically. If that doesn't work please follow the instructions by mikewhatever above.
