So I'm moving in with my brother. He said "buy a router for our computers. old roommate is taking his." so, i bought an airport express. serves my needs, wireless printing and airtunes will be nice. he freaked out because he can't use it to connect his xbox to the internet now. he refuses to be switching any cables around to play it, so now i must fix the problem for him. is there like an ethernet splitter i can buy to get internet to both airport and his xbox? do i need a 2nd router? i REALLY don't want to spend much money at all, but i dont really know what i need for this. hopefully not an entire new router.
