Commiserations - I am in exactly the same situation, had the same experience: telephone support hopeless, after making me try all the usual things like switching channels, rebooting hub etc. they asked me to wait while they were doing more tests, then they hung up. So far support here has not helped either, I am seriously considering to give up and buy a cable router ( the Asus RT-N66U is highly recommended) and use the Virgin hub just as a modem.
I'm in a similar situation. The call centre have reset the router to monitor and check to see if the wifi IS dropping. On the plus side, we were told we are eligible for a free upgrade on our BB speed.
Debating whether to plug in our 2nd router again for Wifi downstairs??
Thanks for posting and welcome to the forums, though sorry to hear of the wireless connection problems. wireless by it's very nature can be difficult to troubleshoot, although I'm not ruling a potential problem with your Superhub.
It may be worth checking out the troubleshooting guide here, certainly dropping the wireless mode to 54Mbps and switching the security from auto to WPA2_PSK has been reported as helping reduce drop outs with some devices.
I had the same problem and solved it by connecting my old Netgear router. The Virgin wbsite recommends switching the Superhub to modem only in those circumstances but I have found that unnecessary. I expect that any decent router would do. Why Virgin supply substandard equipment defeats me.
When watching catch up the wifi drops almost every 10 mins
Wired remains OK
The TV sometimes (not always) displays a message saying the internet connection is lost
I have not tried the last point
As I said in my post, I have solved the problem by switching the Superhub to modem and reconnecting my old router (a standard Netgear one). I doubt very much that this is a channel problem as I live in a large detached house and we rarely get other people's wifi signals. The fact is that my old standard Netgear router worked (and works) well but the Superhub does not as is amply demonstrated by the posts. I simply ask why Virgin supplies a substandard piece of equipment.
