I've been having similar problems with packet loss. Started around 20th december. packet loss graph
I've tried contacting virgin twice online and also ringing them up. they keep saying there isn't a problem. There clearly is - even in the homehub logs it looks like there are errors - apparantly this is fine? I've registered a formal complaint and I'm looking into changing provider at this point.
I logged a formal complaint on 27th December and was promised a call back from a Manager. Still waiting. I cancelled my contract and am looking at other providers as we speak. I will tell everyone who listens to avoid these con artists
I did not appreciate that marking an answer as "helpful" would mean the issue would be marked as "solved". It isn't. I'll look for a way to unmark it. Failing that, I'll start again with the story so far. Easy enough to do as I've written it up to email to a couple of journalists whose names and contact details I had from an acquaintance.
