I'm not too experienced at networking, so I'm hoping someone can help me with a (hopefully) simple problem.
I have a PowerBook 12" with an Airport Extreme card, an FP iMac, an Airport Extreme Base Station, and DSL internet access.
I've got the PowerBook 12" interacting just fine with the AEBS via AE card. What I'm having trouble with is the wired connection (via LAN port) between the iMac and the AEBS. Basically, I can't get the iMac to "see" the AEBS, even though they're linked by a fresh new RJ45 cable. Airport Setup Assistant detects no Airport hardware, and the Airport Admin Utility does not see my AEBS. I therefore have no internet access and file sharing is not possible.
I can't find much on the Apple support site that might help me. Can someone give me some pointers on what to do or check out? I hope I'm just missing something silly, given my general inexperience.
