Been having issues with my V6 box - a few times today and yesterday the tv has basically dropped signal or flashed off for a couple of seconds then back on again and I've had to reboot for it to work again. The TV doesnt show no signal, the lights on the box and the router stay exactly the same and show no sign of an issue. I've rebooted the box and it continues. Checked TV service - no issues in locality. V6 has now started re-booting on its own volition. All connections are good and TV works fine. Bizarrely this happened last month at a similar time for a few days but then went ok with no intervention.
I am having a similar problem and not sure if it is internet/wifi connection or V6 issue. Not been able to use catch up/on demand etc last two evenings and no recordings also TV guide squiffy. Got the error C230 and did as previous post and switched on/off but arrow icon continues to flash. Seems ok during the day. Fairly low user too, only a max of TV and 2 devices. Oh, and couldn't get a Virgin TV to go on my laptop. Typical that the service is not there when people need it at Christmas.
