My setup: Brand new Airport Extreme Base Station MC340LL/A. Set up with WPA2/AES. Also have iPad 1.
My problem: The iPad 1 will NOT connect to the AEBS on the 5 Ghz 802.11n band. It always connects on the 2.4Ghz band, no matter what I do. (I verify this by looking at the Wireless Clients detail in the Airport Utility.)
However, the iPad 1 connects to another 802.11n router I have on the 5Ghz band just fine. And, my Windows laptop connects to the AEBS on the 5Ghz 802.11n band just fine. So it's just the combination of the two: iPad 1 and AEBS; that won't select to connect on the 5GHz band.
The iPad 1 DOES connect to the AEBS via 802.11n protocols on the 2.4 GHz band, but that's not what I want it to do. I want it to connect on 5Ghz.
Details: Yes, I've tried "forget this network" and reaccessing it from the iPad. Yes, I've tried turning wifi on and off. Yes, I've tried resetting my iPad. Yes, I've reset the AEBS to factory settings and redone the whole setup. Yes, I've tried all the appropriate wireless radio settings on the AEBS, same results. Yes, both the iPad and the AEBS are at their latest software levels, as well as the Airport Utility. Yes, the 5GHz channel is wide open with no interference (verified using inSSIDer). Yes, I am sitting about 30 feet away from the AEBS with no walls in between so the signal is fine.
My support issue: for some reason I am not going to be allowed to submit a question directly to support, even though I bought this AEBS a week ago! What gives with that?
