Hi,
I had a similar wireless problem when I started using openSuSE.
But then I found out about ‘install_bcm43xx_firmware’ from this forum. I just plugged into a wired network and typed the command and wireless worked fine.
A page that will probably have the answer your problem is:
http://en.opensuse.org/HCL/Network_Adapters_(Wireless)
If not try:
Ndiswrapper - openSUSE
other useful pages for someone new to either linux of SuSE are:
Users FAQ - openSUSE
OpenSUSE Basic Training - openSUSE
Additional YaST Package Repositories - openSUSE
Hope this helps,
Barry.
