Going to have to go with the others and say that if MoCa isn’t working, there’s a bigger problem (PowerLine is always a bad idea). Make sure: You have the PoE filter (no “S”, there’s should only be one) installed on the entry point only. Since you said “filterS” it implies you have multiple throughout the network. If so, that’s the cause of your problem as those are designed to prevent MoCa signals from passing through. Next would be the main splitter. You really should have only one in the house, and it should be good quality and support up to 2500MHz. Bamf makes good ones. It should only have enough taps as cables you need to connect (don’t get a 7-way splitter if you only have 3 cables). For any unused splitter ports, make sure they are terminated. Check the connectors on each end of the cables and replace any that are loose or flimsy. MoCa really does work very well, so I suggest you figure out what the issue is instead of looking for something else. The only thing I can think of as a showstopper is if they nailed through (or stapled too tight) when installing the wires in the walls. That would compromise the cable and there’s not much that will be able to handle that.

I've had a positive experience with a pair of cheap moca adapters to get wired net to a far room in a house with old coax in the walls. Splitters are absolutely something to avoid. RG6 coax plugs are also notorious for getting right; definitely check all the connections in run if not the whole tree; one rogue strand might be a problem. Try only a straight coax run first to test and then add back all the splitters and other devices.

Re: multiple PoE filters for MoCa.. My MoCa network was terribly unstable with a filter at the entry point, until I also added a 2nd filter on the cable going into the modem. No idea why, but wanted to add this in case it helps anyone. Lots of trial and error but once figured out, the network has been extremely stable for years. Also make sure all splitters are compatible with MoCa (some aren’t) These are the adapters I use. https://www.amazon.com/dp/B088KV2YYL?ref_=cm_sw_r_apin_dp_F0B1FKTK1FRWAJYCJKZE https://www.amazon.com/dp/B088KV2YYL?ref_=cm_sw_r_apin_dp_F0...

  It’s because frequency range for MoCA overlaps with the upper frequencies of DOCSIS3.1. The modem was probably receiving/transmitting in the MoCA range and that data looked like junk. Installing a PoE filter at the modem prevents both of these at the cost of not being able to utilize some of the DOCSIS3.1 range which may result in reduced speed if you’re paying for 1Gb+ from your ISP.

+1 on ditching PowerLine, they've been shown to exceed local RFI limits by turning all your house wires into a giant radiating antenna[1] but somehow they haven't pulled them from the market. The cynic in me says this is because it only tends to impact HF bands, if they they hit > 400mhz I'm sure they'd be gone tomorrow.

Because of some cable run through cement, among other atrocious coax work I needed to reuse, I ended up with two splitters. I needed to run MOCA and DOCSIS over the same span, but also needed to filter out the DOCSIS on both ends (to not leak MOCA into the neighborhood and to not conflict with the MOCA on the modem that had its own temperamental issues.) Two of these worked perfectly as combo splitters and filters. I have a backhaul cable connecting two of them together, and then the correct signal leaves out each applicable port. "Input" goes to the modem on one end, and the cable provider on the second splitter. M1 and M2 go to MOCA on each splitter (4 total). H1 is the backhaul between the two. https://www.amazon.com/gp/product/B07CQTHL33/ https://www.amazon.com/gp/product/B07CQTHL33/

Hold on, I setup a few powerline kits in a few buildings and never had issues once you have it working. It's not as great as cat6 but it never crashed or gave up if the power was on for years. I'll agree the first generation had its problems and wasn't the best or most stable (late 90s or 00s I forget but it was like 10mbps) and I don't count that. It also can't usually jump breaker panels so if you go in knowing this limitation the 200mbps gear I've used is a solid solution but wifi has usually beaten it with mesh these days.
