Lagging Internet While Gaming

[Chanti333]

We recently swapped to the Gigafast 900MB broadband, guaranteed a minimum of 600MB download, but when housemates are playing COD there is constant lag! At times even Youtube struggles. I check the speed on SKY and it always says it's fine with the speed to the hub being 703MB/s but then when I test the broadband it says 215MB/s to my hub so I'm confused. All I know is this connection is terrible and I'm starting to regret changing to SKY. 

I have reset the router several times but to no avail. Any ideas what I can do to speed up the internet? I haven't paid for MAX so cant prioritise devices. Heard about the powerline plugs, is that going to be the best option? There is no way of connecting via an ethernet port. The device is in the next room, only through a wall and approx 4m away!

@Chanti333 Two things to do, get a long enough Ethernet cable to Plug into the hub and the PS5, set the PS5 up for wired network and test!

After that you can look at Poweline, as you distance is fairly close you may not suffer from too much Lag, you will not know that until you try them, take a look at the AV1000 range from Tp-Link.
