Hello,

I have a Deco M4 wich is set up to be the main router and the ISP (cat 5e) cable goes directly into the Deco M4 and I do not have any other routers. My issue is that when I restart the router manually by removing the power cord, I am getting the full promised speed i.e 400Mbps on my 5ghz channel, however after a few hours the speed drops to 100Mbps on the 5ghz and 2.4 ghz and does not go beyond 100Mbps. 

I have also set the Qos to 400 and not added any devies to the Qos list. 

Also to add I restart my router manually because thats the only way speed goes up and when I reboot it throught the app it stays at 100Mbps :(

Is my router faulty or is anyone else facing the same issue with their Deco M4?
