So here is my deal. I have an airport express base station which i use as my router. It works just fine when i have it as my wireless router for my macbook and my pc when i have it locked using a WPA password. When i have it locked though it will not work with my xbox 360 and linksys wireless gaming adapter (http://www.amazon.com/Linksys-WGA11B-Wireless-B-Game-Adapter/dp/B0000AJVBW) which i have. When i unlock the WPA and leave the airport express unlocked it will work with my macbook and my xbox 360, but it then wont work with my pc. I do not personally care about the pc, but my wife does. I also would like to have it locked and WORK with all three devices. Anyone have any suggestions for this lost soul???
