BCM4311 wireless not working on Xubuntu


running lspci -vnn | grep 14e4 prints this:
Code:
03:00.0 Newtwork controller [0280]: Broadcom Corporation BCM4211 802.11b/g WLAN [14e4:3211] (rev 01)
b43-fwcutter is installed, as is broadcom-sta-common. I understand that these drivers like to blacklist each other, so I have tried to load them with modprobe. No luck. iwconfig shows nothing, and the system tray has nothing about any wireless network interfaces. The machine is a Hewlett Packard Pavilion dv6000.

What can I try? Would any other information be useful for diagnostic purposes? Thank you for your time.

If it's Xubuntu, did you enable the "Proprietary Drivers for Devices" Ubuntu repository. In Synaptic, it's under Settings-->Repositories-->Ubuntu; I don't know what package manager Xubuntu uses. The Broadcom drivers should be in that repo.

These repositories are enabled and the Broadcom drivers are installed. When I run iwconfig, it does not see the wireless hardware.

Hmmmmm. It always worked for me with *buntu on Dells. I am fresh out of ideas.

The only thing I can come up with is this, and I know it's kind of lame: Boot to the Live CD and test whether the wireless works with the Live CD. If it does, there's something borked with the install.

Oh, there is this: try a different network manager. I was quite happily using wicd with Ubuntu and, after one web upgrade, wicd just stopped working. I installed Gnome network manager and it worked like a champ with no other changes (no, I never figured out why). If you are using one, it might be worth trying the other.

I hope someone more knowledgeable than I comes into this thread. I would like to know the solution almost as much as you.

Thank you, frankbell, but I am also out of ideas. I've tried the obvious. The hardware switch is on, it shows up running lspci, but Linux doesn't see it as a network interface device. Any help or suggestions would be greatly appreciated.

Have you seen this how-to:

https://help.ubuntu.com/community/Wi...Driver/bcm43xx

I think you will have best results with the Broadcom STA driver (not b43).
