I'm trying to connect an AE to my PC using XP with a D-Link DIR-655 WiFi router. I've used the airport utility and connected the AE to my router via ethernet. It appears to be setup properly and I can see it on the D-Link software. After disconnecting the ethernet cable and with the AE sitting next to the router it continually shows up and then disappears. The light is green on the AE. Then I disconnected the power and moved the AE into the place where I'm going to use it. Now it will show up on my D-Link software occasionally but the light won't turn green. It also doesn't show up on the airport utility software. I also have a Touch and ATV that both work fine on the same network and the same location. The AE is about 30 feet from the router with only one wall in between them. Am I missing something here or could there be a problem with the AE? I'm no expert on WiFi and appreciate any assistance you can provide.
