Poor speed test when connected via Ethernet
I'm having a night mare.
My virgin hub 3.0 is upstairs in the spare room on 350mb package.
Speed test shows 372mb Ethernet connected. The problem I am having is trying to get a good solid Wi-Fi connection downstairs in the living room, which is at the front of the house. The virgin hub is upstairs in the spare room back left of the house.
I connected the first deco via the Ethernet and went through the app setup. If I do a speed test with the deco next to the hub using the provided Ethernet cable I get 389mb but if I connect it downstairs via cat6 Ethernet a get 84mb ?
I have also tried to use the Ethernet backhaul but not matter what I do I still get 80-90mb on the second deco downstairs ?
