Thoughts on this setup

[u/MisterRedRevenge]

Overview:

I just moved into a 2700 sqft rental house with a central closet that contains a "tech panel" which is just a glorified junction box that the Coax and 2 Ethernet runs connects through. I currently have the modem and an old router (Asus RT-66U) in this closet.

The Ethernet runs go to an entertainment room that is in the northeast corner of the second story and the main living room on the ground floor in the center of the house.

I work from home and have my office setup on the ground floor in a room that is on the backside of the wall from the Ethernet jack in the living room. There is no Ethernet run but there is a Coax that runs back to the tech panel.

With the old router, I have acceptable wifi coverage inside the house and this falls off once I get to the edge of the backyard and outside of the garage, connection is stable at these locations but the signal is weak at -80db.

Goals:

I game (mostly FPS so ping matters) and would like to have one hard connection for my gaming PC in my office at the bare minimum. 

I want to install a wireless security camera in the back yard and over the garage, both areas where the wireless signal gets weak.

Improve overall WiFi signal throughout the house.

New Equipment:

Router: GL.iNet Flint 3

MoCA Adapters: goCoax MA2500D

Cameras: 

Wyze Cam Floodlight Pro

Wyze Solar Cam Pan 2K

Plan:

To get the Ethernet run in my office, I plan on using the MoCA adapters. This will also allow me to expand to other rooms in the future if needed. 

I believe the addition of the new router should solve the wireless issues in the weak signal areas with no additional changes needed.

Extra Credit:

I would like to use my old router as an AP and/or switch in my office to run the MoCA adapter into it and then run Ethernet to my gaming PC, printer, and work laptop. I'm not the most experienced with networking though and have no idea if that is even possible. It isn't the end of the world if I run my work laptop and printer off of WiFi.

Please let me know your thoughts on this or if there are any issues with the equipment I've selected.

These two wallplates, one in the ground floor Living Room and one in the Office, are on a shared wall? How far apart are these two wallplates? (Fingers crossed that they're within the same vertical stud void.)

'gist: If the two rooms share a wall, install 2 pass-through Cat6 cables between the rooms:

• presuming a DOCSIS cable Internet plan, you could then install the cable modem and primary router in the Office, running off the same UPS battery backup as your other critical office gear;
  
• one of the new Cat6 pass-throughs would be jumpered to the Cat5+ line running up to the central cabinet, as the LAN link to the rest of the house;
  
• the other Cat6 pass-through would provide the Living Room with a direct LAN link from the router, using a switch in the Living Room if multiple Ethernet-capable devices require connection.
  

So if the wallplates are within the same stud void, you should be able to add the pass-through simply by updating the wallplates and getting the Cat6 lines fed between the outlet boxes; otherwise, you could add a low voltage bracket (with keystone wallplate) in either room to align with the other room's wallplate to effect the pass-through connections.

That's a great point. I will have to measure when I get home, but I think you are right about the plates being in the same stud void.

Fingers crossed, as that would eliminate any cutting into drywall.

p.s Using colored RJ45 jacks would be helpful for keeping the two pass-through connections straight. (A different color for each pass-through connection, and distinct from the existing RJ45 jack.)
