I've had 2 engineers out who gave me two new routers, the first because he had no idea what the problem was so he replaced the router and the 2nd because the replaced router packed in. I've gone from wireless to wired, and still during games my ping will spike from 30 to 70 or 140 then back down. There's no viruses on my PC and when I lan round friends houses everything is fine so it is a Virgin problem.
The forum is flooded with people with the same issue, what the hell is going on and when is this getting fixed, I don't want "everything looks good from our end" response because there IS something wrong!
over utilization is the issue, loads of post on the same issue here, the engineers replace stuff that not failed, because its the only way to exit your property with little or no hassle, it can take them a long long time to resolve this
