Since January, I've had my older g/b model of airport express set to "join the network," which is an 802.11n airport extreme connected to my cable modem. Until last week, the ethernet port of the airport express could be used to connect my DVD player or TV. I could do software updates on the DVD player, and watch youtube on the TV, etc. The connection became slow last week, so I decided to reconfigure the airports. Since then, the ethernet connection to the airport express is no longer recognized. Please note, although the airport express is not an "n" model, this set-up did work just fine! The DVD or TV was automatically able to display my IP address. The express has a green light, it has no errors in Airport Utility, and AirTunes still works just fine it's only the ethernet port that has become completely inactive. Any thoughts?
