Slow speeds on M100

I have been suffering slow speeds for months now, but the situation has recently become much worse. Most days, speeds rarely exceed 50Mbps, but in the evenings they are often in the single figures. I've tried rebooting the router, including a full factory reset, but nothing seems to help. My nextdoor neighbour who is also on Virgin is experiencing similar problems. Any help, gratefully received!

Re: Slow speeds on M100

Your Hub stats are looking good and the Network log is not reporting anything major.

What speed do you get at >> speedtest.net << with a direct connection using a Cat 5E/6 cable between the Hub in Router Mode and a 1Gbs capable Pc/Mac/Chromebook and no other devices connected ?
