I have an Airport Extreme (old model) with an Airport Express (old model) extending my network. I picked up one of the new Expresses today and I am trying to use it to extend my network further. Using the Airport Utility I can find the new Express and I try setting it up to "wirelessly join my current network" and I get to the point where I choose my network name and enter password. I filled out the info properly, but when I press "continue" nothing happens. It simply stays on the same screen... I tried setting it up manually... I can change the Express name, but when I change settings to join my current network and Update it never becomes visible and I have to reset it with a paperclip. Its like it freezes up. Is the new Airport Express not able to join my network? Any suggestions?
