need wireless AP help

[pow3rslave]

so i've got a wireless access point, it's a d-link DWL-900ap+ whirlpool link.
our place has a wireless network in place already, consisting of a D-link DI-624+, DHCP-ing and using wpa-psk.
all of this runs sweet, except what i want to do is use the access point to connect my XBox (original one running XBMC) via eth, and have the xbox able to connect to my network.

the dlink stuff came free from a mate of mine, and when i brought my xbox round to his, all this was acheivable, though i don't know if he ran wpa-psk or just WEP.

can anyone who isn't as wifi spastic as me help?


**********edit ******
just figured out one of the probs, the firmware upgrade on the AP allows it to do wpa, but not wpa-Psk
