1. XP SP2 and yes
2. Yes (at least I believed so 'till today)
3. Just tried to set router exclusively to WPA2 with AES (no combinations) and had to connect withwire because all my computers refused to connect wirelessly.
Obviously some kind of incompatibility.
Even though if I had set combinations before, it showed in available wireless networks "Connected - Security WPA2"


Now Ihave it set to WPA TKIP and so far no problems.
Looks like I've got to settle for lowest security but be able to share filesand printers.

And I've tried everything. Netbeui, re-install drivers, restart router, you name it.
