Hello, I recently had to move my xbox downstairs, when it was upstairs my Wireless router (BT Home Hub2) was positioned close to the wireless adaptor and I had no problems, now the router is in another room blocked by a wall from the Xbox wireless adapter, the adapter when I scan for networks isnt picking up my router, sometimes it will detect that its there but it wont enter IP, DNS or anything, then when I go to test the connection it will of course not connect, I will scan for networks again and it has disappeared. Is the wall blocking it somehow? I cant move the Hub any closer. Any advice?
