TV Artefacts

in Everything for MoCA

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

Did another check.

Enabling Ext-Band was possible if I have reduced the Tx rate from 10 to 8 on the adapter near the TV.

Unfortunately the network speed was much lower (avg. 50 mbit/s).

So far disabled ext Band with full Tx rate is the best solution and provides avg. 550 mbit/s.

Update 2:

changed the band to D-Low AND D-High but without D-Ext and this fixes all the artefacts on TV while the connection remains between both devices. Only the speed is depressed now.

So the extended band seems to be the problem here.

Update:

I have tested my old TV (Samsung 55" KS7090) on the same wall outlet with the same cable: no issues at all.

Tested again with my current TV (Samsung 65" QN90A): again artefacts.

So obviously the current TV seems to be more sensitive.

Any recommendations to fix that on the current TV?
