Firmware v1.8.1.7 CR2 [Oleg] - updated ( CR2a )

There are number of reasons - wrong key, bad or old driver, bad settings on your windows box.
Just read your other post. Looks like Intel driver does not support AES + TKIP at the same time.

I was under the impression, that ASUS offered us with TKIP+AES the possibility for multiple stations to connect with WPA-PSK authentication concurrently no matter if they have TKIP- (All) or AES- (many) encryption.
The station (or card) driver (for example intel) should only support one encryption method (TKIP or AES) at a time.
The ASUS gives us the possibility to access the WL-500G with AES or TKIP concurrently and it should not matter, as the WL-500G makes the choice with which method will be connected.
I think the ASUS can't make the right decision when TKIP+AES is choosen, between AES and TKIP when a station has TKIP.
When using AES on the station (= card) side it works.
