Also the same here, across any game, constant fluctuating ping during the evenings, rebooting the SuperHub settles it down for a little bit before it continues again, here are my screen shots of the ThinkBroadband ping:
I knew yday id put one on, but could not find it - typed another ! tsk!
Have you not had any luck with CS either?
I called them last night - he definitely took the **bleep**, I kept asking him if what he was suggesting would help, and how, and he blissfully ignored me as though his p*** poor English was excusable -
I noticed tonight what actually he asked has reset the hub totally - something I told him I had already done and was not happy to do again, and he said it wouldn't!!!
Unacceptable service Virgin - can you track the call and register a complaint from me please -
