Atrocious Internet Connection

It is the same thing over and over for the past two weeks. Turn off your router and Wi-Fi box. Then do a speed test only with a LAN cable, not Wi-Fi. Does anyone connect their cellphones via LAN cable to their router to have internet connection? Getting tired of Home Connect. Never solution driven, only excuse driven.

I am paying for a 75mbps line, but I am getting internet speeds of up to 3.21mbps. With the internet connect completely dropping on a daily.
