Asus rt ac1900 u speed drops, on New install it showed 185mbps. After a short time it dropped to 130mbps wired and 80mbps wireless I have only 2.4ghz available. But the router supports 5ghz, could this be interfering? Also its connected to a ps4 pro with cat 5e cable. Also a devolo powerline set-up connected with cat 5 cable. And Also a smart tv. Also could the dynamic static ip be of importantie? At a loss here..... Thanks all
