Hi All: I've been having the same WiFi connectivity issues mentioned by other people. With my Airport Extreme Simultaneous Dual Band, I couldn't even run the Speedtest app to completion more than once or twice before the X would drop the connection. Other people have mentioned that it seems to be related to 802.11n - that 802.11g access points weren't having issues. Many people with Airport's aren't aware that you can configure the radios in a much more fine-grained fashion than is immediately obvious. You can set it up so that it runs 802.11n only on the 5Ghz band, and 802.11g on the 2.4Ghz band. To do so, start up the Airport Utility, then go to the "Wireless" tab. There's a drop-down for "Radio Mode", which normally only shows three radio options. On a Mac, hold down the Option key ( Presumably Alt on Windows ), and THEN click Radio Mode. You'll see about a dozen new options. I chose "802.11n only ( 5 Ghz ) - 802.11 b/g" This should ensure that clients that have have 5Ghz receivers still get the benefit of having the high speeds from 802.11n, but that 2.4Ghz clients see only a B/G access point. After making this change, my X has NEVER dropped the Wifi signal. I've run literally dozens of Speedtest checks and it works every time. So, if you have an Airport Dual Band, you might want to try it out. People with other AP's should see if theirs offers equivalent functionality.
