Hi,
I live in an appartement. The internet and TV signal is attached via cable.
Unfortunatelly I see a lot of pixel issues / artefacts in TV signal once MoCa network is running.
Any help for that?
I use 2x goCoax MA2500D and the official SP-2 splitter and the PoE filter from the same package.
Below you can see my installation path:

The internet modem/router (AVM Cable 6600) uses DOCSIS3.1. Due to that I have installed the recommended PoE filter based on the description from here:

Every 1-2 seconds I see artefacts in TV signal. It is somehow matched to the traffic ethernet LED on the goCoax device.
Best Regards
Pixelation with MoCA setups can often be fixed by checking splitter quality, PoE filter placement, or coax terminations. Sometimes just swapping cables helps too.
In moments like these, I find calm in reciting سورة الواقعة—it reminds me that patience and clarity go hand in hand, even with tech glitches. Hope your setup gets smooth soon!
