Whole House Internet - Mesh Networking Over Coaxial

My challenge during the last few months was to find a solution that could cover my whole house with suitable speeds.
The solution I used is NOT the cheapest but is a compromise if you want the reliability of a cabled network as a backbone and an off-the-shelf Mesh Wifi Product. So there were two options (and a third option with not having a cabled backbone at all)

Option A: Call in a contractor to pull CAT6/CAT7 ethernet cables. And then fix all the wall holes and repaint the walls. This might have been a better option, but the added cost of pulling the cables and fixing back the walls. If I could do this I would have preferred this.

Option B: Use MOCA 2.5 adaptors over existing Coax cables in the house. A MOCA 2.5 adaptor was the next best thing over pulling CAT6/CAT7 ethernet cables.

Option C: Most Mesh products are able to use Wifi as a backend. One could do that.

I did use Option C for a short while, it worked though. However, I wanted the reliability and the additional bandwidth of a cabled connection.

Products used

1. ActionTek 2.5 Moca adapters

2. Eero Wifi (I got an older generation, not the Eero 6.) But the good thing was that each device has 2 ethernet ports. This could be used to connect the eero's up to get a wired backbone or can be used to hook up cabled-only devices. I used them to hook up my PS4 and my TV.

3. COAX Filter, totally optional and not needed in my setup as I did not multiplex the Internet signals and the MOCA signals over the COAX cable. But since I ordered it, I used it.

4. A COAX Splitter. I already had this installed in my home. But I guess you can use this one.

Connecting the first eero was plain simple. You do need to install the Eero app on your mobile phone. It is a shame they don't have an App for Windows 10.

The cable from the ISP runs into my basement and this where my modem/router combo is located (provided by my ISP).

I connected the Eero device to the modem/router combo, used the APP to set up Eero. In minutes I had the Eero working.

Although optional I'd highly recommend going into your modem/router combo and change the configuration to "bridge mode". Once in bridge mode, you have to restart the Eero and it will work. Do note that the Wifi on the modem/router combo will now stop (but you have the Eero for that).

Alternatively (but Eero doesn't recommend) you can put the Eero in bridge mode. You'll lose certain features from Eero security though. Eero security is a paid add-on service. If you plan not to pay for it, then it doesn't matter, does it?

This one is simpler than it looks. Just connect the coaxial cable on one side of the adaptor and the ethernet cable on the other side. Power up the adaptor and it works.

I installed the adaptors in the basement (where I take the lead connection from my first eero device), and then also in my two other rooms that will provide me with the coverage I want.

Connect the other two eeros using the ethernet cable from the Actiontec MOCA adaptors.

Power on the eeros and use the eero app to set them up. It is that simple. From the Eero app, you can see that the eero is using a cabled connection to the "Gateway eero". We are all good here.

Also, and optional, you can choose to use Eero Secure or the Eero Secure+ at an additional cost. I have instead opted to use custom OpenDNS FamilyShield instead.
