Main router from "Suddenlink" Cable Company. Doesn't reach all upper and lower floors by itself. I ran an ethernet cable to the farthest room on the ground floor and another one upstairs. I have a Mikrotik router plugged into each ethernet cable and the devices connect to that signal. Works perfectly. My house isn't that big, but it has steel beams that can interfere with the Suddenlink router. Microtik routers solve the problem at a reasonable price.
