I can honestly say, without hesitation, that since my hub was changed (which I was told to leave for a short period of time, for it to settle down), my WiFi has gone down every day. I am constantly turning it off and on, which makes very little difference.
If you are listening Virgin, I pay a lot of money each month for, what I would suggest, is a very poor service. I can't afford to upgrade, but judging by some of the comments on the forum it wouldn't make any difference.
I am now also getting pixilated pictures on some of the channels, which is causing a lot of frustration.
Virgin, if you have a problem, it is time to be transparent. I have spoken to a small selection of people from different areas of the UK and they confirmed to me that they were having identical issues.
Something is wrong, what solution are you working on?
