Downstream power is borderline (a bit too high) for an ex telewest connection, can you also post the upstream?

[Zhadnost]

Post the details on virgin.support.broadband.cable and you will be more likely to get someone to investigate the issue.

I had the same problem recently and they traced it to the UBR I was connected to (lots of users on same UBR appeared to be being affected).
