My connection went from 3 bars to 1 bar! And im lagging ALOT online and im always leaving parties becuase it automatically kicks me! Im using a wireless connection to xbox live and it has worked amazing until now. My computer is a floor about my xbox. I also have 2 labtops and a wii that may use the connection, but even when only my xbox is being used it STILL lags! And I do have a router of course. netgear router
