I have been playing MW2 and lately (this week) I started noticing that it was running slow and lagging and my connectivity bars went down to just one. I turned off my PC and that seemed to help MOST of the time. I am running wired (not wireless) and everything that is connected is close to all sources and I checked with AT&T today and they said their side is good.
So what do I do? I cannot keep going like this with it sometimes working and sometimes not working.
Also, I am not the most tech savvy person so please keep answers simple. :)
