Until two days ago my v6 boxes could see each other and play recordings. Now they see each other but can't connect, i get a whirling blue wheel followed by an C423 error telling me there's a problem with connection, box is unplugged or i haven't got the box anymore. None of which is applicable.
Boxes haven't been moved.
My wifi is fine, I've run speed test, i've tried switching off and on again both boxes and the hub. I've tried reconnecting them both to virgin media services - no problems there.
Never used ethernet before and all worked fine so i'm not about to start having wires everywhere now.
What is the solution without resorting to ethernet cable?
No problem watching On Demand on either of the boxes and wifi signal is good. As you say C423 is normally associated with wifi issues, but that isn't the problem. In the end i rang up, after running tests which found nothing wrong, they sent a signal out to the boxes which overnight has resolved the issue.
I note recently there a fair few posts in forums about this issue, but VM don't seem to have it clocked as an issue. If after doing all the re-boots of boxes and hub doesn't work and wifi is ok, i'd recommend ringing. Might be a lengthy wait, but at least it seems to get it resolved.
Wouldn't it be great if the Tivo software was more intuitive in the help section, instead of signposting you to the website or having to ring, having a way by which the appropriate signal to resolve issues could be sent automatically after a set of diagnostic questions.
