wpa-psk & repeater

DL 624 router 108G
DWL 2100 Access point - set to repeater moder - 108G
DL G520 adapter - 108G

client - pc xp sp2

all equipment with current firmware

I am able to configure the set up with and connect to wireless network
through windows management albeit with very weak signal.. When attempting
to configure via Dlink software , same thing . However, once repeater is
enabled, wps-psk is not recognised,and am unable to connect. Dlink says 1.
should work or depending on who you talk to, say that 2100 ap set to repeat
mode will not work with wap-psk coming from router

Dlink also says adapter is not compatible with windows management and wont
pick up signal from repeater.

Anyone know the facts? Especially re Ap in repeater mode not recognising
WPA_PSK from router.
