Long-time lurker, infrequent poster here.... I've been using the AEBS with my PowerBook for the last two and a half years with no problems. I was able to set it up to work with my Verizon DSL internet service pretty easily and never gave it a second thought. Until now. I recently moved, and of course I had to switch ISPs. Now I've got Comast cable internet. The technician came out and hooked everything up. My internet works just fine - so long as I have the ethernet cable plugged into the computer. I've tried to set it up to work with the Airport but it's not working. I'm clearly doing something wrong (this is what I get for not paying more attention to how these things work). Anyone else using AEBS with Comcast and would give me simple instructions for how to get this working properly? Much appreciated.
