I called a virgin media technician out to check wifi, he got it to 200 next to the hub, but this dropped to 4-5 where my PC is.
I bought a TP link Deco S4 wifi mesh to replace the woeful wifi from the hub 3.0. The technician recommended a wifi mesh such as this.
I've set it up and it works wonderfully, with the exception of the 2nd V6 box upstairs, which now has no internet at all. The main V6 box has internet, and the wifi is working wonderfully throughout the house. Why isnt the 2nd box getting internet? I cant see a cable that should be connected?
