I have an airport base station version 2 hooked up to a cable modem. My stepdad wants his WIN98 machine to be online too. We bought an ethernet cable to go out from the base station and into his pc. problem is, he cannont get online. he can only get online if we plug his pc directly into the cable modem. if we go from the modem, to the base station, to his pc, it doesnt work. do they make an ethernet cable that goes from one end to two? that way we could split the conection, with one end going to the airport, and the other end going directly into his pc. where would i buy such a thing, or would i have to make it?
