We live in nw6 and currently have virgin media (the 50Mbps version). For the most part it's fine - but speed struggles a LOT during weekday evenings like some times recorded speed tests at less than 1Mbps. This is with only myself browsing the web and my wife maybe the same. It means nothing internet related can really happen - and crucially we can't login to work VPNs etc.
Virgin reckon there is a traffic fault which is under investigation but won't be finalised/fixed until Jan 2018...
We are not really heavy users - a bit of Netflix and in the evening likely at least one of us (two) are VPN'd to our work.
So question is : what has the best stability in the evening? -all the speed tests for my postcode suggest we have great broadband on average and a speed test I did just now was OK. But we can't afford the v poor performance. Is BT better than virgin media for this aspect? Also is there any way to see average speed test data in my area by provider averages thorough the day ?
