Hi, I'm trying to help a friend with establishing a connection to an Airport Express station. He wanted to be sure Airport wireless would work with his Apple at his house. He has a Motorola Surfboard 4200 Cable modem already attached to his PC via USB, and he wants to extend connection wirelessly to his iBook. I tried just connecting the USB from the modem to an Aiport Express and it doesn't work. I tried via ethernet and that didn't work. My question is, does the Airport express work as a router as well? Because if not, I guess thats what the problem is.
