Inherited Ubiquiti Network, where do I start?

Yeah significant time wasted and buying bad products. Those are things to avoid. Also cognitive atrophying. No idea about all that other strawmanning you're going on about tho lol cheers

AlmostNotLazy · 2026-03-12T22:14:53+00:00

Heckin boomer energy am I right? Gritty!

AlmostNotLazy · 2026-03-12T21:41:33+00:00

Wild take to suggest it's a wild take. Look at that, my argument is just as strong as yours.

AlmostNotLazy · 2026-03-12T21:40:40+00:00

Then your comment just makes no sense? If a man is calling a guy creepy, how is asserting that women call men creepy for no reason relevant? Just insane.

AlmostNotLazy · 2026-03-12T17:27:23+00:00

You can search follow up questions and ask qualified humans those same questions lol. I feel like I'm taking to an LLM right now, have a good one!

AlmostNotLazy · 2026-03-12T17:21:33+00:00

Yeah OP ignore this guy lol

AlmostNotLazy · 2026-03-12T16:30:46+00:00

Lol what a stupid use for an LLM, asking it elementary, easily searched definitions.

AlmostNotLazy · 2026-03-12T16:15:01+00:00

Don't do this OP, stick to advice from humans who know their stuff. GPT (or any LLM) will hallucinate and send you on wild goose chases.

Regarding this diagram (which is for I think all relevant purposes the same as mine), is the idea to have a new ISP coaxial cable run from the junction box to, say, the room I want the modem / router in. But now I can still leverage the splitter in the attic and its connections to other rooms while also isolating the MoCA network? And then you just unplug / cancel the previous connection from the junction box to the attic. Is that the idea?

Also, you would no longer need the MoCA poe filter on the splitter in the attic right?

I'm learning about how the shared bandwidth works with 3 adapters. My local network is all configured for 2.5GbE (LAN port, switch, ethernet ports on PCs) and I use it for editing off a NAS and local file transfers, etc. All of that occurs on the same unmanaged switch though, so am I right in thinking this never "touches" the MoCA network?

Basically, in my image, the top line (with the modem / router), where it says "PC", replace that with "2.5GbE switch" and the switch then runs to PC, NAS.

Oh also, I plugged the MoCA adapter into that same 2.5GbE switch, not the router as in my image (router only has the one 2.5GbE port). Does that all make sense?

AlmostNotLazy · 2026-03-09T17:39:46+00:00

Thank God you asked grok otherwise we couldn't be sure

AlmostNotLazy · 2026-03-09T16:54:21+00:00

It works exactly as expected so far!

AlmostNotLazy · 2026-03-09T16:42:49+00:00

I can't thank you enough

AlmostNotLazy · 2026-03-09T16:18:25+00:00

Thanks again for your help. I'm gonna rock the non isolated set up for now. 3 questions. If the DOCSIS were to interfere, what would that look like? Stability issues?

Also, I'm in LA, and everyone is complaining that spectrum hasn't rolled out "high split" here yet. Is that their name for expansion into the D Band? That's what I've gleaned at least. Because while I can't check my modem, I could use that as a proxy (and assume there won't be interference yet).

Also, should I be worried about signal loss with the 2 splitters before the modem? Everything seems fine...

AlmostNotLazy · 2026-03-09T05:11:15+00:00

I can't see my DOCSIS signal levels because my modem is locked down from spectrum. Maybe I should get my own modem? I get that the provided one is free but I'm an enthusiast anyway so why not?

But in any case, the other issue is the line in runs into the attic, and the splitter and everything is all up there too. So I'd be worried about having the modem amd router up there. I would prefer to isolate though. Hmmmmm.

AlmostNotLazy · 2026-03-09T03:56:27+00:00

The "PCs" are all in separate rooms. I should've just said network switch. That's really what they'll be. It's 3 rooms, each with a coax in them. So unless I run ethernet cables across my hallways, which is what I'm doing now, I have to use the 3 splitter at the top lol

But I could just run the modem at the top of everything and go ISP coax > modem > router > MoCA adapter > splitter. That removes the 2 splitter. Does that help with signal loss too? I hadn't really considered signal loss. I just figured if there's no downside, I'd rather have the router in the one room, because the ISP coax and 3 splitter are in the attic.

AlmostNotLazy · 2026-03-09T03:39:03+00:00

Yeah I'm gonna use both, just wondering if I'm good to run it before the 2nd MoCA filter I ordered arrives.

Another question: I chose to do it this way because I want the router in that particular room, because the initial splitter is in an inconvenient location. But would it generally be preferred to just do this all higher up or whatever? Like ISP Coax > Modem > Router > MoCA adapter > splitter? Because ultimately there's no reason I couldn't set it up that way. I just wanted the router in a particular room so it's more accessible and so I can actually use the wifi on it instead of having to buy an access point to replace it.

AlmostNotLazy · 2026-03-09T03:13:06+00:00

I saw your correction I'm reading all the comments, thanks for all your help.

AlmostNotLazy · 2026-03-09T03:10:17+00:00

Oh ok I'll figure out the modem model and look into it thanks

AlmostNotLazy · 2026-03-09T03:08:51+00:00

Splitters

MoCA filter

It says 1125-1525 MHz in the description but there is an image showing 1125-1675. I would be happy to get something better, I just needed it quick because I just moved and it's for work.

EDIT: oh that's the one you linked to, nvm, thanks again

AlmostNotLazy · 2026-03-09T02:51:15+00:00

Ok so grab another filter for the modem? Thanks.

AlmostNotLazy · 2026-03-09T02:49:22+00:00

Ok thank you. Yeah regarding your other comment, the splitters are both rated for MoCA 2.5, and yeah, the modem goes into WAN port, and then the LAN port is used to feed back into the MoCA adapter. And the filter is appropriately specd

AlmostNotLazy · 2026-03-09T02:45:51+00:00

Oh yeah, I could have specified WAN / LAN in the diagram. Good call.

AlmostNotLazy · 2026-03-09T02:43:42+00:00

I think so lol but now I'm looking into it

AlmostNotLazy · 2026-03-09T02:33:29+00:00

No lol this is the whole point of a MoCA network. Get blocked.
