I've just started having this very problem, my hub has now reset itself several times, it's getting really annoying. Did anyone ever find a fix to this, it's obviously done a full factory reset several times itself so I have nothing left to try.
My Superhub has been resetting itself regularly ever since I got the notification that I had been upgraded to 100 Mb/s (~the time that the warning went out from from Virgin to users that they should not use the default passwords provided with their routers). It has been driving my kids nuts - and me, by extension, when I get home.
It used to reset every now and again, which was annoying enough. But these days it is resetting every four or five days (sometimes less) and when it does, it looses all passwords (both to log in and for the WiFi ) which it never did before.
Apparently it reset itself less than an hour ago and I have taken screen shots of the router status pages but there are no errors logged and there are not any high voltages etc. (maybe there were spikes earlier ... but they are not recorded now)
I addition, the WiFi range has always been a bit suspect (I have just been too busy to complain about it).
If a member of the Forum team could help me sort this out, I would be most gratified.
I get the same resetting issue as the other comments on this thread. Please could you let me know what info is required from my side for support analysis? Alternatively, can I get a replacement hub sent given that seems to be the typical outcome anyway?
