Hi could anyone please give me any advice on the best set up ps4 with the w9970, would it be worth me purchasing a ac 1900. I seem to have ok internet streaming, just gaming is so laggy have tried upnp off and on and have 0devices when using wired connection. My isp is talk talk but all I have to test signal is Speedtest and bqm’s. It seems much worse at weekends. If I had a pc or laptop I may be able to do a better diagnosis, any help much appreciated. Also when my snr was 5.2 upstream things were amazing I think it’s something to do with error protect and the Dlm can’t be changed back to fast path that’s down to open reach.
