XBL Lag

[Killer Mantis]

Lately when im on xbl, specifically left 4 dead 2, i lag hard when playing with multiple people. I use the same ethernet cable for my ps3 and dont lag at all when im playing that.

Is there any way i can fix this?

Sometimes it may be the server that is causing lag. Left 4 Dead 2's servers are known to be extremely laggy at times.
