I have used Mythbuntu, Ubuntu 12.10 32-bit OS, and they have all worked properly with the wifi driver which is apparently the Broadcom 4312. Then I deleted the Linux partitions, rebooted with Ubuntu 12.10 64-bit because that was the only 64-bit version I could find. I did it through USB boot, installed alongside my Windows 7.

I noticed before installing that it couldn't detect wifi connections so I used ethernet. It installed as quickly as the 32-bit version of 12.10. I finally got to the desktop environment after rebooting, and I noticed that I still couldn't connect to my wireless internet. I've browsed for hours and hours to get it working, but I still have found no answer. I hope someone can help give me a working yet simple solution. If not then I guess lay it down on me the hard way.

  • What is the exact identity of your Broadcom? Run this terminal command and pick out the Broadcom wireless. Edit your question to add all the details: lspci -nn

Your device, 14e4:4315 uses the Broadcom STA driver. Please get a temporary wired ethernet connection and do:

sudo apt-get install linux-headers-generic
sudo apt-get install --reinstall bcmwl-kernel-source
sudo modprobe wl

Assuming the wireless switch is on, your wireless should now be working; check:

rfkill list all

  • 'kernel source missing' indicates that linux-headers was not installed or installed incorrectly. Please try again: sudo apt-get install linux-headers-generic and then do sudo apt-get install linux-headers-$(uname -r) and then try again: sudo apt-get install --reinstall bcmwl-kernel-source ; sudo modprobe wl

  • It looks like you typed bcmwl kernel-source; it is actually bcmwl-kernel-source.

    I assume you said Y. If not, please do so and then please go on to the next one: sudo apt-get install --reinstall bcmwl-kernel-source We're close, Warren!
