Unfortunately I don't have any terminator caps handy. Should I still try without?Cap the unused ports with 75 ohm terminator caps.
I forget what the freq range is for moca 1 & 1.1. That splitter also may only be one way. No harm in trying it as is though.
I do see something that may be an issue. In your latest diagram, you have the Antronix splitter as 5-1002 MHz. From what I know, MOCA 2.5 functions in frequencies above 1100, so that splitter may be blocking some of your signal. Just a quick thought.
Correct, whole-house PVR is working, TV is working, cable modem is working but MoCA 2.05 is still dropping intermittently.To recap then, the whole-house PVR is working, TV is working, cable modem is working but MoCA 2.5 is still dropping intermittently yes?
If I disconnect the Cable modem, I won't have internet. Are you suggesting to try that just to see if the adapters stay stable but don't actually allow me to go to the internet?Out of curiosity, have you tried the current configuration but disconnect the Cable Modem (but leave everything else on) to see if the problem with the MoCA 2.5 adapters goes away?
Here's what I could find on the modem:Do you happen to know if your modem is DOCSIS 3.1 by any chance? DOCSIS 3.1 cable modems can interfere with MoCA 2.0 and 2.5 since they use a larger frequency range in the downstream.
Regarding the 3db attenuator, it wasn't provided by my CableCo. I added it based on a recommendation received after observing high tanges in both the upstream and downstream signals on the modem.You said you have an atttenuator at the point of entry (PoE), which I assume is because the signal from the street is too hot (high), and is needed for the modem.
I recently received my adapters and now have them up and running. I have noticed that my connection is dropping randomly. I have tried to isolate the issue but am getting inconsistent results.
I'm not clear on a number of setting options in the MoCA adapters and need help to ensure I have them optimized (in case this could potentially be the issue). I have attached screenshots below with my current settings which are identical on both adapters. I also followed the instructions provided with the adapters (step 3 to connect cables, step 4 to log into management web, and step 6 to encrypt). Again, I did successfully get the adapters to work via short run - same room testing and then again over long run to desired locations. For whatever reason though, the connection is not stable.
The one setting I did change was LOF based on advise received from @Datalink in another forum.

Given that I'd like to only use D-High band, what value should I set for LOF on both adapters?Next, LOF is the RF frequency to which the MoCA interface was tuned when last operational. Normally, the devices in the same network will share the same LOF. No need to change them. Except you want to change the MoCA band. For example, you want to use D-band high now, not Ex-D band.
Should the NC be enabled for both devices or just one?The Last, NC negotiation. NC is the network controller. Normally, the highest MoCA Version device in the network will be the Network Controller. By default, we should enable the negotiation, especially there are some old MoCA version devices in the same network.
I will give this a try at the next possible window. With the whole family stuck at home, they aren't to fond of my taking down both cable and internet. I'll report back once I've completed this test.I echo @degrub . Unplug everything, even the modem. Start with just the 2 MOCA adapters and check the transmission rate/stability. Then, one by one, add devices, checking transmission and stability, until you see which one is the issue. If you start off with instability, then it may be a cabling issue.
I have completed a few preliminary tests and wanted to share these early results before going deeper. After connecting the adapters MoCA ports directly using the coax run from the basement to the second floor (no splitters in use), I noticed that the PHY Rates were still low. I decided to test with all bands enabled to see if there was any difference... and as you can see by the results below, the rates jumped to where they should be (I think). I then tried to go back to D-High only (via updating settings on both adapters, saving and then rebooting), but the second floor adapter has yet to connect. Is it possible that D-High alone is what's causing my instability and low rates?I will give this a try at the next possible window. With the whole family stuck at home, they aren't to fond of my taking down both cable and internet. I'll report back once I've completed this test.
After you changed the MoCA band, normally you need to change the LOF at the same time. Then save and reboot.Just following up to see if anyone has any advice or guidance to share about my posted results. Thanks
