I have a gateway (router and modem) from my ISP that is located upstairs in the office. The home is really old and the downstairs has really bad connection via wifi. Luckily there is another coax cable from the office upstairs going downstairs to the room I would like to setup another source of wireless. I currently have a wireless mesh system but it cuts out every once in a while and doesn't perform super well. I was thinking to use a MoCA adapter downstairs since the gateway supports MoCA and connect the ethernet to the mesh system as a wired backhaul hoping to increase strength quite a bit but I also have a extra router laying around. I was running this plan through chatgpt (lmao) and it said I could just use a splitter at the ISP line in and run one line to the gateway and the one going downstairs to the router and set it up as an access point (by disabling DHCP) since the router has coax port. Would this work? Would the splitter reduce the signal too much or would this not work entirely and I would then need to purchase a MoCA adapter (which are pretty expensive for some reason).

If similar to the following setup, then no, it will not work.

Question - I need help with my home network setup ?
I need some recommendations on what to change. This is my current setup. My internet is "fiber" but not really. They advertise as fiber but it is converted to coax from the box outside. Inside the main network cabinet there is coax that is split. One side of the coax goes to a Arris modem/Wi-Fi...

It seems like that OP had a working setup with a coax split into two networks but I understand it may be a fluke. If so how exactly do I use the MoCA enabled gateway? It is my understanding that you only need one MoCA adapter if you have a MoCA enabled gateway.If similar to the following setup, then no, it will not work.

Here is my current setup. There are two separate coax traces, one from the ISP line in and one going to a satelite that is no longer in use that goes downstairs. My plan was to undo the connection to satelilite and use that coax as internet to downstairs. How exactly do I do this with a MoCA enabled gateway? The gateway has only one coax port for line in. Wouldn't I then need a MoCA adapter going from ethernet from the gateway to the coax? But I thought I don't need a MoCA adapter on the gateway end if it is MoCA enabled. Do I need some kind of splitter?

The link I provided already pointed out that OP's setup is incorrect and he did have issues.
If your downstair's router is also a cable gateway (no RJ45 WAN port, but with a coaxial connector as WAN) , you can't use a signal splitter since your ISP will not give you 2 IPv4/IPv6, also mentioned in the link. You will have to use a Moca adapter connect to one of that router's LAN port, and use that router as AP (with DHCP server disabled). Or that router is also Moca enabled?
As usual, list all of your modem/gateway models so I/we can lookup the specs.
Bed time here though.

Oops I messed up, the 2nd router I have is actually not a cable gateway, it only has a RJ45 port labeled internet (assuming this is WAN) and 4 other LAN ports. I also have an extra modem with a coax and I confused them for each other. So I'm assuming there is no way to have the modem act as simply a switch to convert from coax to ethernet.
The main gateway I have is Technicolor CGM4981
The extra router I have is netgear ax1800
The extra modem I have is arris cm8200 (I don't think its MoCA enabled)
I'm assuming I have to use a splitter somewhere to use only one MoCA adapter.
