We have had a red light on the front of our hub since install. Having read posts in the past it seems this can be a common issue, so we have left it. Not withstanding it is nigh on impossible to actually 'speak' to someone even if we wanted to!
We have had poor signal strength in parts of house, even though it is a small terraced house. We got a wifi booster which I am not sure has made too much difference!
We keep getting intermittent download speeds and working from home on video calls this is poor.
I have tried all the usual resets, restarts etc but nothing seems to work for very long.
I wish we had never removed the BT service as that ran 100%, 100% of the time. Virgin is pants!
