No network connections after install

English Network/Internet

All was ok on USB LIVE but after installation I am not able to configure Mobile Connection.
When I open the networks, I see an error that says “this version is not compatible with my network cards” or similar.

thanks

Have you tried to reboot?
This could fix it already, if it was working on the USB Live. See: openSUSE 12.3 Release Notes

If not, try entering YaST->Network->Network Settings, and switch to “User Controlled with NetworkManager” (on the “Global Options” tab). If that’s already selected, switch to “Traditional Method with ifup” first, click “OK” and enter it again to switch back to NetworkManager.

Switched to “User Controlled with NetworkManager” and that fixed the problem.
