Super hub 3 has seriously let me down for the past 2 wks every 1 to 10 mins it is buffering on YouTube & I cannot even use Prime Video at all.I think it’s time to tell Virgin to shove the hub 3 were the sun don’t shine.
How are you connecting the device to the Hub, Wi-Fi or ethernet cable ?
What speed do you get at >> speedtest.net << with a direct connection using a Cat 5E/6 or better cable between the Hub in Router Mode and a 1Gbs capable Pc/Mac/Chromebook and no other devices connected ?
Have you checked the 'Check Service Status' at the top of the page ?
If nothing is showing try phoning 0800 561 0061, this will tell you of more local issues that may be affecting your district. Be aware that it isn't a manned line.
Go round all the accessible internal and external co-ax connections and ensure that they are finger tight.
If everything above is OK we need do some more troubleshooting; to start with …
Disable any VPNs that you have running.
Can you set up a Broadband Quality Monitor (BQM) at thinkbroadband.com - this will give you an insight into what is happening with the signal at the other side of the Hub, it will take a few hours to get any kind of trend showing although you should post the link straight away.
Post a 'Live Link' to your BQM on here.

Click the lower link (Share Live Graph) then click generate.
