Hi all, apologies for the late reply. The hub is a 3.0, yes I've done all the tests and still it flashes green (for over 24hrs now). Called VM at 9 this morning, got thru to a not so helpful operator. Did all the resets and tests again but no joy. The earliest time an engineer can come out is in 7 days and when asked if a new Hub could be posted out I was flatly refused. I told them the problem is with the Hub and sending a new one out could fix all this but he wasn't having any of it. Sorta screwed now, so sent a stinker of an email to VM so will see what happens. It would be quicker to jump to another BB supplier as I'm out of contract.
I'll give an update when or if I get one in due time. ( Still don't know what the green flashing light means).
