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.

  • Have you tried this ? http://askubuntu.com/q/55868/35775 – Web-E Mar 10 '13 at 05:30
  • yeah but i havent been able to use any of those,they all seemed valuable but broken links and/or not the right thing,im scared because its been a problem for several years and still unfixed – warren Mar 10 '13 at 16:27
  • 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 – chili555 Mar 10 '13 at 16:34
  • it says Broacom Corporation BCM4312 802.11b/g LP-PHY – warren Mar 10 '13 at 16:41
  • I think it says more than that. The 'more' is what I need to see: 14e4:???? – chili555 Mar 10 '13 at 16:45

  • thats about everything from the second half of the terminal – warren Mar 10 '13 at 17:06
  • I still don't see the numbers. Did you add the -nn flag to the terminal command? lspci -nn I just hate to guess and give you a frustrating and wrong solution. – chili555 Mar 10 '13 at 17:07
  • no and ill do that now – warren Mar 10 '13 at 17:10

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 – chili555 Mar 10 '13 at 18:15
  • It looks like you typed bcmwl kernel-source; it is actually bcmwl-kernel-source. – chili555 Mar 10 '13 at 18:17

  • im gonna try again – warren Mar 10 '13 at 18:21
  • can this be resolved via remote desktop? – warren Mar 10 '13 at 18:24
  • just copy paste the commands. – Web-E Mar 10 '13 at 18:27
  • alright well the last error message is what i get from the commands :( – warren Mar 10 '13 at 18:31

  • Run each command one at a time and post the result: sudo apt-get install linux-headers-generic. How does this go? – chili555 Mar 10 '13 at 18:35

  • I think we're OK so far. Now the next one: sudo apt-get install linux-headers-$(uname -r) Result, please? It may, I hope, say it's already installed. – chili555 Mar 10 '13 at 18:49

    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! – chili555 Mar 10 '13 at 18:54

  • Ok, now how about: sudo modprobe wl?? – chili555 Mar 10 '13 at 19:00

  • So now is your wireless working after you detach the ethernet? – chili555 Mar 10 '13 at 19:06
  • ahhhh :"D ITS ALIVE!!!!! thanks,you're the best,do i require rebooting? ,oh and before i got rid of 32 bit version,i got rid of it because it was only a read only file system,would i worry about this in 64 bit? – warren Mar 10 '13 at 19:09
  • I would do nothing but enjoy your wireless. Update Manager will probably want to install whatever was skipped above. Please accept my answer above and have fun! I doubt you will have any read-only issues but post a question here if so. – chili555 Mar 10 '13 at 19:11
  • Problem solved for me in DELL inspiron 1545 (broadcom) + Ubuntu 12.10 (may need to prss fn+F2 to enable wireless ) – totti Apr 22 '13 at 10:24
