Haven't changed anything. The only difference is my usage is 109gb this month. When I play games the ping jumps from 90 to 999 constantly every 5 seconds (does not matter what server or game I am on). The internet is usable as it keeps getting disconnected every 5 mins. I suspect my usage has a cap of some sort. I have gone through all the broadband help tutorials, made no difference (not really surprised).
