Got my DGL-4500 in today and love it huge speed and range boost

but im having one problem. The router keeps blocking my Xbox 360 and other devices (PSP NDS etc.) Do i need to somehow register the devices with my router? (all my other devices such as PC, PS3, WII all show up automatically and work fine) i looked all over the settings and couldn't find anything. any ideas?
heres an emulator of the routers v1.00 (i currently have v1.01) menu if it helps at all.
