I have been having what sounds like a similar problem.
My router reset itself a few times running up to Christmas, wireless SSID etc reset. The admin password to login was also seemingly reset so I could no longer login. This happened 2 or 3 times and when I contacted the VM team they ran some tests and said everything was fine!
Yesterday the same happened so the SSID etc were all reset again, again my old admin password no longer worked.
I had to do a factory reset to put everything back to defaults in order to login and then set it all up again. Then contacted VM support to see if there was a fault on the line etc but again was told they could see the router was online and all looked OK.
This morning the same has happened. SSID no longer appears and no-ones devices can connect. Obviously support is offline today as its Sunday so can't contact them before I reset the router again.
Getting frustrated now with this happening again and having to re-apply the hub settings but being told by support that there's nothing wrong.
Was the only solution a new router? Is the admin password reset what other people were seeing with this fault?
Edit: router downstream and upstream screens attached.
Is that a Superhub 1? If it is, then it's 10 years old and a useless piece of kit anyway.
If it's a SH2, then there's a know wireless issue.
In both the above circumstances, the VM bods will offer you a new Hub 3 when they get to this thread in a week's time.
That said, the stats at the particular snapshot look perfectly good. But the T4 timeouts are not accompanied by T3s. So it may be that your downstream has glitched a few times which prevents keep-alives from being returned to the VM end; hence the T4 events which reset your hub. The VM bods may be able to comment on that.
Sorry to jump on this forum as well but is there any chance you could arrange a replacement for me too?
I have an old superhub1 which has been restarting at least once a day for the past 8 months! the restarts are getting more and more frequent. - lately 3-5 times a day and usually defaulting to factory settings meaning I lose all SSID information and passwords etc.
Thank you for the steps you have already taken to try and resolve this issue and sorry that it remains unfixed. Are you available to talk to our Web chat team today? Our team will be able to check on your account and do some troubleshooting steps with you. We can do this via online chat.
What is the point of having a Forum Team if all they can do is point the suffering user to a very poor online chat ‘service’?
You already know the answer: Because it's all about keeping costs down for VM, regardless of service quality. I'd guess that the chat service is provided by the same third world prison that hosts Virgin Media's first line tech "support" and customer "service", and the inmates are paid a quarter or less of the cost of VM's UK based staff (I'm not assuming that they're paid as such, but VM would have to pay the prison authority to use convict labour).
Roll on the (probably long distant) day when Openreach offer FTTP or G.fast in my area, and I have a choice of supplier.
