I am in an apartment complex with a wireless internet connection for the complex. I own a PS3, a Wii, a 360, a HP Pavilion laptop, a Sony Vaio laptop, and an HP pocket PC. EVERY SINGLE INTERNET USING SYSTEM/COMPUTER Has a full 100% connection; EXCEPT my stupid Xbox 360, while I am playing COD4 on Live my connection goes from 1 bar(red) to 2 bar(yellow) then will jump to 4(perfect) back to 1 then to 3. and so on and so on! BUT EVERYTHING ELSE IS PERFECT!
What is wrong with this, and how do I fix it?
