Hey, my friend is moving to a new flat and he has an internet coax connector in his soon-to-be living room, along with TV coax (female) and another one (male) which I’m not sure what it’s used for, but I’ve heard it used to be for radio. This is obviously the place his ISP is going to place a modem when he arranges his internet contract. The problem is he would like to have a full speed internet, ideally 1Gbit, in another room, and he only needs it to be in that room, but the flat has no ethernet wiring, so no RJ-45s anywhere. I came up with two possible solutions for this that avoid running CAT cables or buying an expensive WiFi router and hoping it’s going to be reliable enough.
Use the the “other than TV” coax as an extender for the modem input cable and place it to the room he wants his full speed internet to be in.
Buy an Ethernet over Coax adapter (and reciever) and use it to run internet to the other room with the modem in living room.
Both solutions assume that the “other” coax can be rewired so that the living room one is directly connected to the one in the other room.
I’m not sure if any of those two are possible. Problems I see:
a) I’m not sure if the “other” coax has the same properties as the internet one and if it can handle the same data flow. Are the coaxes in the walls usually the same? Or does it really matter how “good” the coax cable is for this to work?
b) I’m sure that the ISP is not gonna like solution no. 1, but after all, they don’t have to know we moved it.
c) I’ve found some Ethernet over coax devices, but most of them are designed for IP cameras and I didn’t really find a gigabit one. I kinda like the second solution more, so if it’s possible, do you have a recommendation for an EoC adapter that can be used in this case?
