As its a new Hub it may need resetting as below
______________________________________
Do a Hub “pinhole reset” - first make sure the 2 passwords on the Hub sticker are still there and legible first ! Disconnect any ethernet cables from the Hub (leave the coax connected), and then with the Hub still "switched on" throughout, press pin in firmly with paper clip/SIM tray tool or similar "thin thing" and hold it firmly for at least 60 (a timed sixty) seconds, release the pin, leave for 5’ to stabilise - dont manually switch it off at any time. Passwords will reset to those on the sticker. See if that sorts it. If not try the reset one last time and hold pin longer.
Then... Can you test speeds this way on a new ethernet cable
____________________________________________
Connect a 1GB enabled computer/laptop, with up to date drivers, via a NEW and working Cat5e/6a ethernet cable, directly to the Hub which you have put into “modem mode” (
https://www.virginmedia.com/help/virgin-media-hub-modem-mode ).
This ensures that NO other devices are connected
Test speeds at
https://speedtest.samknows.com/ - try on 2 different browsers.
If they are still low – boot your device into Windows safe+networking mode - to disable any potentially interfering software - and try again.
There are many posts on here (I have a list of ~30!) where QoS software, unknown/flaky software, old network card drivers, corrupted browsers, bad cables or other connected devices are limiting speeds on tests.
Report back what that gets.
