Just an FYI, for all openSUSE11. users who have the bcm43xx chip-set in their wireless device.
1 ) make sure you are on a wired connection first
2 ) open a console & type in this
3 ) this *should* install the necessary firmware for your device. re-boot to activate the device,then, go to YaST - network devices - network settings & set up your wireless device as normal
Hope this helps someone :D
