yea it is 192.168.11.1 (i think that is correct)

here you go

it should be lol, my xbox is hardwired to the router, my laptop is wireless. i had this set up fine on my old pc, the problem started when i got onto windows 7 on a new lappy.

yep it is, im online right now, when i am on the xbox and i do a xbox to pc test it cannot find the pc but..... i have just connected my laptop via Ethernet and it has picked it up so why not wireless, is there a setting i have overlooked somewhere? i have just pinged the xbox and i get request timed out even though the xbox seamed to find the pc ok. lol this is a mystery.
