Ive got this weird problem with my router, ive got a 360 and desktop pc wired to it and laptop working off it wirelessy. The router is in my bedroom beside the desktop. Everything works fine while im not in the room but as soon as i step in the room the connection is lost and wont reconnect till i leave the room. I dont even have to touch the desktop or switch the computer on i just have to step in the room and its gone. The weirdest part is its only me that seems to affect it, my sister and brother can go into my room and surf away everything works fine. It's like it recognises me! its freaking me out. Im completey serious here, has anyway heard of anything like this happening before?
