Since the storm last night, I can't get my Mac to connect to the internet. My roommate's computer, connected to the same router, has no such problem. Any suggestions on how to troubleshoot? Is it most likely my ethernet card, or could it be a cable or something? Any easy way to find out? It's an iMac G4, the desk lamp kind, so it's not as easy to open up and replace pieces as most macs. Thanks for any help... I'll just be twitching quitely in the computer until I get my access back...
