Lost Network Connection after Update.

I have had DSL setup in Yast under Network Basic that worked fine until I did an Online Auto Update (i think). running 8.1. and a second manual update where I installed the new NVIDIA drivers. All my settings: Domain, gateway, etc check out fine and are setup for my ethernet card. And my DSL modem is on. (works in WinXP). Is there somewhere else i can setup my connection better than YAST or am i maybe missing something since my update. The message is "local host not found" Thanks in advance for getting me started.
