Supposedly the default high security setting (WPA2) is actually both WPA2 and WPA, but I can't get any device without an adapter that is specifically WPA2 compatible to connect. This includes both a desktop PC with a PCI card G adapter and of course, my xbox 360. FWIW, I my Tivo connects fine with the new airport using the new proprietary adapter that tivo sells. Also, my airport admin utility doesn't want to work right either. I get an error message. Strangely enough the error message doesn't prevent me from modifying the settings. I can still work on the settings, even though the message won't go away. Here is the message I get: Thanks for your help. I'm starting to think the cost and the issues I'm having with this device outweigh the good looks it has and the high speeds it's capable of.
