I just got ubuntu installed on my laptop but I can't access the internet on it. I have a flashdrive and another laptop that's running windows and does have internet access. I tried downloading firmware-b43-installer to the windows laptop and then moving it over to the flashdrive. But I couldn't figure out how to install it from the flashdrive back onto the ubuntu computer. How can I get it installed onto my ubuntu computer?

Chill's sudo commands all seemed to go through but the internet still didn't work. The dmesg command gave a ton of output:`[ 11.974594] b43-phy0: Broadcom 4331 WLAN found (core revision 29)

Download the file b43.zip from this forum thread: http://ubuntuforums.org/showthread.php?t=2316899&highlight=b43.zip Transfer it to the desktop of the Ubuntu computer on your flash drive. Right-click it and select 'Extract Here.' Now, from the terminal:

sudo mkdir /lib/firmware/b43
sudo cp ~/Desktop/b43/*  /lib/firmware/b43
sudo modprobe b43

If your wireless doesn't start immediately, reboot.

From your dmesg, it appears that your device also requires the "mimo" firmware files. Please remove the older, unneeded folder from your desktop:

cd ~/Desktop
rm -r b43

On my Dropbox account, I have the newer firmware files. Please download this to your desktop: https://dl.dropboxusercontent.com/u/58267392/b43_newest.zip Right-click it and select 'Extract Here.'

Now open a terminal and do:

sudo cp ~/Desktop/b43/*  /lib/firmware/b43
sudo modprobe b43

If your wireless doesn't start immediately, reboot.
