Brand New Motorola Surfboard SB6141 and brand new Airport Express with Comcast
I have done some pretty extensive searching and I don't think I have found anything that applies exactly to my situation. I just bought both items brand new today from Best Buy. The cable modem works fine when plugged directly into the computer by ethernet and the iPhones can see the Airport. The Windows computer can also connect to the Airport, but the Airport can't connect to the modem with the same ethernet cable that works fine with the computer (in other words, don't think the cable is the issue). All I get is the solid, then flashing amber light. When I try to connect to the Aiport through the WiFi settings on the iPhone, it says "an unexpected error has occurred".
I have tried the Airport Utility on the iPhone and it can't see anything. Don't have Windows 7, so can't get the utility for Windows.
I'm guessing there is a disconnect between the modem and the router, but I have no idea how to fix it.
