The thing I definitely like with the Hub 6 is that it has its own online diagnostics page where you can check for any issues on it and do the frilly bits like turn off or dim the LED lights on the front
Hub 4 was stable, no issues....but Hub 5 was a right royal pain in the wotsit
Fujitsu lappy was constantly bouncing from Hub 5 to Fon, thought it was the lappy cos its quite old, bought the Lenovo and that bounced like a demented bunny too
Upgraded both lappy's from Windies 7 & 8 to 10Pro thinking that would cure it...no joy there
My smartphone is Windies 8 and that bounced all the time on 5 but is as stable as a rock on 6
So I just got onto BT and explained the issues and they seemed to know the problem was a well known about one as they upgraded the hub without a quibble or argument
