Our house has 3 stories plus basement. I used Ethernet over powerline - which sometimes works great and sometimes doesn’t work at all. Already tried two different brands but I guess our wiring is the problem. The router is on the 1st floor (Ground floor if you’re British) and my office is on the 3rd floor (Second floor if you’re British).

So I thought about MOCA. We do have loads of coax cables in the basement in a utility room which serves as the hub for these. 2 come from outside and were intended for a satellite dish or so, but we don’t use them, we don’t watch TV in our family (The previous owner loved TV). The other lines end up in each room.

When we got cable internet the cable guy used the line that goes to the living room to connect to the Cable relay thingy and connected the router in the living room to the coax outlet. So let’s say one of the cables is already identified.

​

So if I get MOCA I think I realistically need at least 4 devices. Plug the router from the living room in the basement utility room, install one MOCA there for the line to the living room, another in the living room and a cheap wifi router there. then a second one in the utility room that hooks to the line for the 3rd floor and a fourth one in my office and connect another wifi router there.

​

Any dumb ideas in this plan? Any easy way to tell which cable is the right one or will this be pure trial and error? There’s no labeling at the cables which makes it much guesswork. If one cale is broken I guess I could still use the other line in the room next to my office. Wifi sucks when it gotta pass through the floors here, but between rooms it should be fine.
