i have a 120 gb ps3 and my wireless signal is at 70 to 100 percent most of the time. but here for like the past week when i go online on Call of duty modern warfare 2 it only gets a red ping signal all the time. i try switching to another game to see if maybe it the host but same thing every where i play. i have a d-link modem and router, my ISP is comcast though, i live like an hour east of nashville. can any one help me?
