Total home network newbie, so apologies in advance. Didn’t see anything on the faq on point. I live in a condo that has two wall coax points - one in my bedroom and one in the living room at the other end of the unit. I currently have a single Motorola mg7540 modem/router, installed in the living room, with an Ethernet cable direct to my smart tv. Everything else I use WiFi. Currently I have terrible signal in the bedroom; I can move the router modem and plug it in to the bedroom coax, but then I have terrible signal in the living room (and can’t do a direct Ethernet connection to the TV). I saw online that I could connect a second router via Ethernet to the first, but that’s not a great option for me as I don’t have any good place to lay the wire. On the other hand, the bedroom already has a coax cable.

Could I just buy a second router-modem and put it in the bedroom? Would that create two different wifi networks, or would it be possible to have them join?

Is there a better solution I haven’t thought of?

Thanks!
