My Dell Latitude D830 (BCM4311 wireless chip) is unable to connect to any wireless connections or even detect them. I was able to find a driver for it but I don't know what to do with it. The driver is a .tar.gz file.

Please edit your question to add details of your wireless device from the terminal command: lspci -nn | grep 0280 – chili555 Nov 21 '13 at 21:44

Please get a temporary wired ethernet connection, open a terminal and do:

sudo apt-get install linux-firmware-nonfree

Detach the ethernet and do:

sudo modprobe -r b43 && sudo modprobe b43

Your wireless should now be working.

Even with the wired connection, it doesn't seem like it is able to connect. – user218120 Nov 22 '13 at 5:21
