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:
If not try:
Ndiswrapper - openSUSE
other useful pages for someone new to either linux of SuSE are:
Users FAQ - openSUSE
Hope this helps,
