hey i got x box live at the moment but i have to keep my x box wired to the router on the downstairs living room T.V but i wana have x box live in my room but i do not have a phone socket to plug the ethernet cable into so was thinking about the microsoft wireless x box adapter. (from game for £60) but i was wondering if it was worth the money.. will the connection be un-playable and laggy if i have my x box upstairs and my router downstairs or will it work all the same, please answer people!!! (i got a Netgear2 wireless router)
