problems with xbox live and access points

[protorso]

i have a speedstream 4200 ethernet/usb adsl modem. and a belkin enchanced wireless router. model number- f6d4230-4 v1.

i put a access point on my router and now my xbox live will randomly get disconnected and when it disconnects me my modem will have the dsl light flashing. but without a access point mine and my sisters laptop will not connect to our belkin router.

on the system log on the speedstream router management says this
