Hi, I just received my new Airport Express. I want to use it to replace my non-Apple router. (Dlink) My non-apple router has a cable going into it labelled DSL. That is the only cable going into it (except the power). The end of the cable is like the end of an Ethernet cable, just smaller. I can't find a plug hole on the Airport Express that the DSL cable can go into. Is there an adapter or something that allows me to plug the DSL cable into the WAN port on the Airport Express? What should I do?
