Broadcom BCM4311, Ubuntu 12.04 / 13.04

Chili555, GREAT news! Got wifi working. Here's how it happened. First, I threatened laptop that if it does't start working, I'm gonna use it for target practice. I let it think about it over night. Then I fired it up a couple of times with/without ethernet AND toggled fn + f2 . YEE-HAW! I got wireless from 2 blocks away. Must have been the threat that got it to work. Still haven't figured out how to log on to own wi-fi because of security key needed. Will figure that out later.

I'm off to figuring out how to upgade the bios.

Thanks for ALL of your help and patience!

Welcome Luis_Corbalan

Let us see which wireless chip you have. Please open a terminal (Ctrl+Alt+T is the usual shortcut) and copy & paste this command into the terminal

lspci -nn | grep network -iA2

Then post the output back here.

Be aware that if your chip is different to the one in this thread I will ask for this to be moved to its own thread.

For what it's worth, this is not a universal fix and breaks the wireless connection on some machines. Mine runs fine on the bcmwl-kernel-source but not at all on the nonfree version.

For what it's worth, is yours a Broadcom 4311?

lspci -nn | grep 0280

I just installed Ubuntu 14.04. Dell 1501, Broadcom 14e4:4311. I did not have wire or wireless connection. I ran the remove purge command. The install nonfree command would not run. (Duh-no internet.)
Rebooted.

After the reboot, I had a wired connection. I was the able to run the install nonfree.

Thanks to Chili555.

Please try this:

sudo apt-get remove --purge bcmwl-kernel-source

Reboot and let us have your report.
