It has WPA-personal (TKIP and AES) and WPA2-personal (also TKIP and AES).
Try both.

Mine works in repeater mode, but i had problems when configuring it (with encription). When WPA, it didn't connect to AP, but when WPA2 - my PSP and PPC couldn't connect to it
I was surprised when I discovered option called "WPA-auto-personal". With it everthyng worked wonderful!

Try to find such option there
