Home MoCA connection with XB8 gateway

I currently have an XB8 gateway and am running into issues with the MoCA setup. The way my network is connected right now is as follows: 1st floor coax outlet -> coax splitter -> one output into XB8 -> one ethernet port to a router. 2nd floor coax outlet -> MoCA adapter -> desktop PC.

Am I just missing a PoE filter on the input side of the splitter on the 1st floor? Or is it possible that my coax outlet on the 2nd floor isnt connected? Or do i need to feed a coax into the splitter again from the gateway?

Is the splitter MoCA compliant (5-1675 MHz) such as this one ?

And by all means, be sure to install a MoCA POE filter.

The last time I checked, I saw that my splitter was indeed 5-1675 MHz, but I don't think it specifically said whether it was MoCA capable or not. Does that part matter, or, is the frequency range the important bit?

@Chrisis_L EG gave some great tips. Have you had the chance to check those out? Next I would say we move to confirming if that outlet is active, if it's not, we can send a tech out to activate it.

That's the correct splitter. Perhaps there is a non-compliant one hidden somewhere behind a wall ? Or as you said, maybe that second floor outlet isn't connected. Can you trace the wiring and see ? Are you sure that the MoCA feature is enabled in the XB8 ?

Heya, thanks for the help! I finally got around to re-examining my cables and splitters.

Unfortunately, I tried some things and it seems my problem still persists.

What I did was;

Firstly, I misread the writing on my original splitter incorrectly, and that it was actually only up to 1000mhz. 

I also traced the wiring for the modem to my garage and found another splitter, that was also only up to 1000mhz.

So, I replaced both of them with these two splitters I got off amazon, https://www.amazon.com/dp/B00KO8W9RA?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1, and https://www.amazon.com/dp/B00KO8W93E?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1 

I also put a filter on the input side of the cable going into the garage's 3 output splitter, as well as a filter on my modem's coax input.

I am currently unsure if the garage's coax splitter has a cable that directly goes to the outlet of my 2nd floor, but it does seem to be the case that I might have a splitter in between somewhere.

If anything, here's a screenshot of the modem's webpage.

It says that the channel that it's using is at 1175mhz; does that mean that the splitters I used are working since the range is above the max frequencies of the old splitters?

[Removed image: "Personal Information"]

Should I get a signal detector to see if my 2nd floor's outlet is actually connected?

You're quite welcome ! If you are using the built-in MoCA feature in the XB8, then you can't put a POE filter at the back of it. It will block all MoCA signals. You need to remove it and only have one on the input port of the very first splitter that is directly off of the street feed from the pole or pedestal.

Ok, I'll remove it when I next get the chance, and I'll post an update then! Thanks!

Hello! Back with an update! I've just disconnected the PoE filter on the modem's input, and, unfortunately, it looks like my MoCA device is still not connected.

To restate my current setup, as I think it to be; I have a coax(that I believe to be from the outside) going into PoE filter into the input of a 1-input-to-3-output splitter. One of the outputs of that splitter goes directly(hopefully) into my modem's (XB8) coax input and another one of the outputs(hopefully but dubious at this point) should be directly as a cable to the 2nd floor. Then, that cable on the 2nd floor is connected to my MoCA adapter, this ScreenBeam ECB7250S02 https://www.amazon.com/dp/B08ML634YB?_encoding=UTF8&th=1. I also have an adapter to extend the cable about 4 feet, if that affects anything.

Aside from the dubious cable connection from the 1st to 2nd floor, is it possible that my adapter is not functioning correctly, or should I just reset my modem and see if it detects the adapter?

OK, so you are using the terms "hopefully" and "I believe". Quite frankly, you have to be certain ! Otherwise, you are just guessing.. That said, it sounds like you have everything configured correctly now.

To answer your last two questions, the adapter could be malfunctioning, as could the XB8. And yes, you should try re-booting both the XB8 and the adapter again. You may want to consider hiring a service like the Geek Squad or the one that Comcast is partnered with (Hello Tech) to investigate this: https://www.xfinity.com/support/articles/hellotech-overview 

Good luck and please post back with how things turn out !
