[Ubuntu] Broadcom Wireless STA Driver Activated But Not Currently In Use

Hello Friends,

I am using Ubuntu 10.04 LTS - the Lucid Lynx. I was using Wireless daily with no problem but one week back something happened and my wireless stopped working suddenly. I figured with System > Administration > Hardware Drivers.. that my wireless driver was not in use. I thought of removing it, reinstalling and then re-activate it.. it worked.. but whenever I rebooted my system I had to do the same process everytime.. :(

Tried google and found this blog.. thanks a lot to the writer..

I will just rewrite the steps here for my reference.. :D

All this we are going to do on a terminal.. just press Alt+F2 and type gnome-terminal and press enter..

1. Optionally u can try these commands first.. just to check the connection
lspci -nn
lshw -C Network
lsusb
ifconfig
iwconfig
sudo iwlist scan

Now run the following commands..
sudo modprobe -r b43 ssb wl
sudo modprobe wl
sudo ifconfig eth1 up
sudo iwlist scan
 
2. Blacklist ssb. Run the following command 
echo blacklist ssb | sudo tee -a /etc/modprobe.d/blacklist.conf
 
3. Edit rc.local and add the following code at the end.
sudo vi /etc/rc.local
and add this just before "exit 0"
modprobe wl



Now just reboot... the problem should be gone :)

P.S. I am running ubuntu on Dell 1440.

Cheers!!!

  3. This was not a solution for me until I added "modprobe -r wl b43 ssb" to the rc.local but without you I'd be helpless :D
