Evening mate,
You have x2 issues here, one is the delay in loading web pages, which as you stated relates to the WIFI and then there is the less than stated overall speeds.
Physical bandwidth aside, would suggest we concentrate troubleshooting efforts on the latency of websites first.
From your notes, you were having similar wifi issues with the HUB3? This gets me thinking that the problem isn't on the hub itself.
I presume that webpage loading speeds are fine on other WIFI connections, such as at a neighbours house, or coffee shop WIFI?
Going on the assumption that your devices do load web pages faster on other WIFI connections other than your own, would lead to ruling out causes of latency in your home.
** My first tip would be to unplug every wired device and disconnect every device, smart sockets etc from the wifi other than your laptop and then test several webpage load speeds on your laptop
** If web pages still load slowly after the first steps, make sure that the superhub is upright, that its well ventilated, so not in a cupboard or near a window, move if possible, to somewhere fairly high up, like a book shelf and re-test
** If the above suggestions are still resulting in slow webpage loading on your laptop, download a wifi analyser app like this one

Do let us know the results of the above 🙂
