Can you do the speed tests this way and report what these get
_______________________________________________________
If you think that you have a BB speed problem, then to check the speeds coming in to your Hub properly, and whether they match what you should be getting, you cannot rely on wifi tests, - no BB supplier guarantees those - only speeds "TO" the Hub are guaranteed.
So, can you test speeds directly like this. As you expect >100Mbps then 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 you 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.
Then if the speeds to the Hub are as they should be -but wifi connections are poor - we can look at resolving that side of things
