@Kin. That is a bit rubbish that you are sill having issues even after finally getting full fibre. I've never had ping rate or tatency issues here. I stream via Xbox Gamepass cloud streaming quite often as I have Gamepass Ultimate free with my EE fibre so might as well use it, I use that on my Steam Deck and you wouldn't know it isn't running natively. I will start another discussion about game streaming later.

@JT. I have tended to use ethernet runs instead of Wifi where possible. It's just more stable and consistent speeds. PS4/5 and Sky Steam definitely work much better through a wired connection. Over Wifi Playstation download speeds when installing a new game are crap, and I think it's an issue with the PS firmware.

Last year when I had all the floorboards up in my gamesroom to redo all the electrics and add a lot of extra plug sockets I took the oportunity to run Ethernet under the floor and add some wall sockets. I now have 3 dedicated wall sockets with cables running to a switch in the garage, and then goes to the main router in the wall, I've also run cables to the living room and spare bedroom (just in case), And a few years ago ran an armoured ethernet cable 60m down the garden to our garden office room, but that also has a Wifi extender that repeats the house Wifi, Means I can get Wifi coverage across the whole garden which is a bit mad, but also Sky in the garden room, Eithernet is still far better if possible.
