I won a TV and the sound is horrible. So I bought all new surround sound and airport express so I can play music wirelessly. Airport Express won't connect at my place which just uses the wireless modem. I tried it at the Apple store and at a friends house that uses a modem + router and it was able to connect. I'm connecting this wirelessly, not using an ethernet cord. It recognizes the Airport Express throughout set up. But then when it completes the set up by restarting, it never recognizes it again. So my question is, do most people need to use a router in addition to their wireless modem for airport express to work? Or is it most likely a piece of crap modem that I have from Time Warner Cable that is the issue? My friend uses a TWC modem but has a Cisco router. Long question, but appreciate any tips.
