But they are using virgin media cable and they don't want broadband from BT. Wish they can swap my house.Ummmm
You seem to be getting you, and maybe some of us, confused there max. First you say they are on G.Fast 330/50 and give us a pic of their phone socket, then you say they are on VM Cable and don't want broadband from BT.
Which is it?
Furthermore, precisely 40 minutes and 10 seconds ago you said:-
Connection - Three 4G, tbb tests normally 35-45Mpbs down, 65Mbps off-peak, 9-24 up.
If you never think of anything off the wall, you'll never think of anything original.
