I recently installed ubuntu 13.10 on the computer to get some use out of it. I have no clue why the wifi is not working as a day ago it had Windows Vista and was. I have installed the proprietary driver for networking and it had made it no better. I have also installed all update using ethernet. Why is the wifi not working?

If you have ethernet working, it is quite easy. If you do not have any internet connection on your system, just let me know and I will post a different solution, suitable to this case.

Issue the following commands:

   sudo apt-get install firmware-b43-installer
   sudo apt-get purge bcmwl-kernel-source

Reboot, it should work.

  • @Brandon make sure the module b43 is loaded, by checking modinfo | grep b43. Empty output, it is not loaded: force its loading with sudo modprobe b43. Some output, it is correctly loaded but does not work: in this case dmesg | grep wlan0, dmesg | grep b43, post the output. Commented Dec 24, 2013 at 8:00
  • Alright. I got caught up with school, and the holidays. So I am going to completely wipe the computer and freshly install Ubuntu 13.10. And if it does not work then I will ask what to do.
