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?

The 4311 (at least as of 12.04) still required you to use b43-fwcutter. Look here: help.ubuntu.com/community/WifiDocs/Driver/bcm43xx and here: wireless.kernel.org/en/users/Drivers/b43#Supported_devices –  Bandrami Dec 23 '13 at 5:59

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.

Just did this and made no change. –  Brandon Dec 24 '13 at 7:39
    
@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. –  MariusMatutiae Dec 24 '13 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. –  Brandon Jan 7 at 2:20
    
@Brandon Ok,, that sounds like a fun project. –  MariusMatutiae Jan 7 at 2:23
    
Okay I now have a fresh install with all the updates installed. what should I do next? –  Brandon Jan 7 at 4:27
