Or a damaged Ethernet port. (Agreed that the drop to 100 Mbps max seems too coincidental to be a MoCA/coax issue … at least for the purpose of prioritizing troubleshooting.)
Does the router offer a dialog where the link rates for the Ethernet WAN port and Ethernet LAN ports are reported?
Who’s the provider? Comcast typically will perform this service free-of-charge; that is… grouping and isolating the residence’s coax behind a “PoE” MoCA filter.
Theoretically, you could just upgrade the main MoCA/Ethernet bridging adapter at the router and the adapter at your PC, but the devil is in the details … and the thread is lacking any details. So… maybe.
Brand & model of MoCA nodes and all coax splitters? Any known MoCA 2.5 incompatibilities for existing gear? Are splitters spec’d for MoCA 2.x?
Top component seems a patch panel. What I don’t get is why a patch panel if they don’t have Ethernet/Cat5+ cabling.
since my home isn’t wired with RJ45
Seems like the patch panel & jumpers are just for extending in-room patch cables, to make it look cleaner. I suppose it might improve portability, with the patch panel effectively documenting where the device patch cables need to be connecting. (I’m assuming RJ45 coupler keystones.)
What splitter would work?
For what purpose? For how many locations?
Assuming the one working room is a cable modem location, how many other rooms are you looking to get connected, and for what purpose … cable TV boxes? … MoCA?
Assuming you’re trying to use MoCA, you’d want to use a MoCA-optimized splitter series like that recommended by TomRILReddit, the Antronix MMC1000-B line. Typically, a cascaded splitter setup is used, with a 2-way splitter feeding the modem location and a secondary splitter sized to service the rest of the locations.
You may want to upgrade the pictured “PoE” MoCA filter to a 70 dB model, as well. (Preferably, the “PoE” MoCA filter would be installed on the input port of the top-level splitter, with the filter connected via a short coax line to the ground block.)
These connections would ideally be made inside a protective cable junction box. At a minimum, you’ll want to use weather boots for the coax joints.

Is this a 2-unit building? Seems like the incoming cable service line is already split somewhere upstream (to the left) of the picture scope … with one line running up to the “PoE” MoCA filter and ground block, and the other line connecting to the input port of the passive 8-way splitter at the bottom of the picture. (FWIW, a non-MoCA CommScope SV8G)
ditto what TheEthyr said Re: your ISP configuration simplifying the MoCA setup … but even greater simplification and optimization is possible if just trying to link one remote room to the router LAN; see the following parallel reply by TomRILReddit from today for another thread attempting the same…
they only extend out of the wall about 4 inches each.
Oh, are you referring to the ends at the wall outlets? My earlier comment meant to suggest that you first try ONLY re-terminating the unidentified cables at the outside junction location, making the assumption that those ends are the stumbling block. (And if reterminating the outside ends resolves the issue, I’d also consider reterminating the 2 identified lines, thinking that they may have deteriorated performance, even if not as crippling as the other 5 lines.)
Then, you could try re-terminating the coax lines, starting with the outside connectors.
I would like to repurpose a Netgear AC1200 Modem-Router as a range extender/
MOCA/Switch to add ethernet ports to our home offices.
Easy enough to test: Can you configure the Netgear modem/router in such a way that allows it to be hard-wired via Ethernet to your Xfinity gateway, LAN to LAN, such that any devices connected to the Netgear, wired or wireless, receive IP addressing from the Xfinity gateway? (typical manual configuration involves setting a manual IP for the AP, plus disabling DHCP services)
If the Netgear modem/router can’t be configured to work in this way, it won’t work if linked via MoCA, either. (Best case, you’ll need a separate MoCA adapter to proxy the Netgear connection with the Xfinity gateway.)
Only 2 of the coax jacks inside linked up with a cable outside. The other 5 showed no signal after trying every possible combination.
One thing to check is that the in-room coax outlets are actually connected to a coax cable behind the wallplate. (It happens.)
Then, you could try re-terminating the coax lines, starting with the outside connectors. (example coax compression kit)
