Coax outlets are not wired room to room, but room to a central point. Think of your electric service, which has a central breaker panel where all the wall outlet wires join (meet).

An F81 adapter just allows 2 coax cables from 2 rooms to be connected directly together.

How are you converting from the 50ft coax cable to Ethernet?

Sounds like some wires may not have been punched down completely. Gigabit Ethernet requires 4pairs of wires while 100Mbps requires 2 pairs.

If the coax isn’t being used for anything, then that can make things simpler. But, just because you have coax wall outlets, doesn’t mean they are interconnected together. You will need to locate where the coax cables meet, so you can interconnect them together.

If you are only planning two locations to be interconnected with moca (one at router and one at your room), then interconnecting the two cables with a F81 barrel adapter will create the link. Attach the moca devices to coax wall ports, connect Ethernet to router LAN and Ethernet to your switch, and you are ready to go. Enjoy the speed!

Do you have any WiFi 7 clients?

I have some ocean front property in Iowa you can invest in.

What problem are you trying to solve with replacing the existing router?

You may need to contact the ISP to have the new modem added to the account.

If you just need one additional port, use a 2-way splitter. Connect the input port of the splitter using a short coax jumper, attached to the left side of the tube attached to the ground block.

There would seem to be an amplifier somewhere in the coax line. Maybe the amp is located outside where the coax comes into the residence. This is an old-school method of signal distribution used in many apartment buildings. If you are only using the one wall outlet for the modem, then you may be able to remove the amp and the below CMCDT to direct connect the cable to the modem.

The CMCDT takes signal in and passes thru the majority of the power to feed another outlet(s), while dropping a signal to the outlet. Look for other wall outlets and see if they also use the same device.

Your modem is a router too. Do the other routers support Access Point mode? That would eliminate double NAT.

Powerline will be the limiting factor. You can attach any WiFi access point and or direct attached device (or Ethernet switch to both).

Unless you have coax outlets at the 2 locations or willing to install data cables in the walls, what are your other options? Try and see.

Add an Ethernet switch and connect the PC and 2nd router (set to access point mode) to the switch. Then the pc shouldn’t lose connection because it is connected back to the main router and not the 2nd router.

Is the fiber service connected to the white box in the cabinet or coming in somewhere else? I don’t see an Ethernet cable connected to the white box.

You need to add an unmanaged Ethernet switch in to the cabinet and connect all the blue RJ45 terminated cables to the switch ports. Then connect one of the main router’s LAN ports to the switch or to a wall outlet, which will distribute the signal to the other wall outlets. Then you can connect the other Eero devices to wall outlets where Wifi is weak.

The 32 end points in PON has nothing to do with the number of devices on your internal data network.

Telus isn’t responsible for connecting to interior data cabling.

There is one RJ45 port open on the Telus box in the center. One of the unterminated blue cables runs to the wall outlet you want active. You’ll need to add an RJ45 connector and plug it into the Telus box.

None that will cover everywhere from a central location.
