> There must be something that is fundamentally wrong with the superhub and vm's network.

As the problems disappear when you use a vmng300 modem I'd say it's pretty clear that the problems lie with the Superhub only.

> I mean there is no consistency in the problems.

I think just about all the problems can be laid at the door of dodgy firmware handling the WiFi - if it hangs or overlays memory the symptoms can appear inconsistent. It seems to be stable enough when WiFi is turned off and it's used with another router.

Not legally they can't - look up the WEEE directive which is now UK law.

It isn't and you could insist they take them back but few people bother (WEEE Directive again).
