No wireless in 9.10 with Broadcom BCM4312

[gabbar_singh]

Thanks Eric82. Worked for me after I put the restricted repo in the /etc/apt/sources.list
I have a HP Pavilion dv4

samasat your awesome, After a fresh install I updated the machine first with a wired connection. Then went to system>admin>hardware drivers. It found the fwcutter and STA wireless drivers. Since I don't want to mess with the winblows driver, I'm using the STA driver, which works perfectly. All I had to do was activate it, and reboot, then setup my wireless settings.
By the way I have an HP dv2000 with a a broadcom wireless card (bcm4312)and i'm running 9.10 Karmic Kola.

Wireless now working. (Hopefully for good)

All I did was:

sudo apt-get upgrade
sudo aptitude reinstall bcmwl-kernel-source

I don't know if i'll work for any body else, or me for long. But feel free to try!

Here is a pretty good description of what to do, it can be done from the install CD.

You need just to install kernel-headers of respective kernel version you have and then reinstall bcmwl-kernel-source and everything will work!
