Best high range router for Home

Hello guys. I need a new Gigabit router for my home. I don’t have an IoT home. My house is big, 3 floors 60x20 meters long in each floor. I want to know if there is a router that can suit my needs because I don’t want
to use several devices to accomplish this. I want just one router that can provide internet for the whole house with good speed. Thank you very much for your answers.

You house is too big. It is difficult to use just one device.

You’d better to have cables as backhaul and use one device each floor.

Our best signal router is B2200 which is mesh router and support backhaul.
