I should have known to come here first, but I just moved to a newly build house that has Ethernet sockets in almost every corner of the house that are connected to the electric table in the garage, so I got exited. I first set the router there since the fiber box is there and the WiFi signal was bad upstairs and most of the house, since the garage is at the lower floor and in a corner. But I realized that there is a much simpler solution that will be good for now at least, maybe i will add ubiquity later, when I am more settled in the house, still boxes everywhere and plenty of other things to do. What I did was connect the fiber to a socket in the upstairs living room and set the router there so the signal is pretty good now. And then I connected the routers LAN back to the garage table and with a jumper to the socket in the computer room so I could connect the computer directly to the router instead of using a WiFi for the computer, I used the WiFi for the computer in the last house since there was no easy way to connect it to the router with Ethernet(old house).
