Moved into a place where the builder did not add connectors to the coax runs in the utility box. Before I added an RG6 connector to each cable trying to find the one I needed that runs to my office, I figured I would just plug the copper coax cable straight into the originating goCoax MoCA device, without a connector, just to locate the proper wire I needed. This is what the wire looked like.

I find the right cable, the MoCA lights turn on, everything is working as expected, and I am getting fantastic speeds.
Now, just to add the RG6 compression connector to firm-up the connection between the cable and the MoCA device. I add a compression connector to the cable, screw the connector on to the MoCA device, and now I have no MoCA light and no connectivity. Weird. So I cut the compression connector off, strip the cable again, and just to be sure, I plug the copper coax cable straight into the MoCA device again -- back to fantastic operation. I install another RG6 compression connector, and again I lose connectivity.
I'm using the below RG6 compression connectors.

I'm guessing I may be creating some sort of interference/short with the these RG6 connectors because I'm not installing the connectors correctly or because the compression connectors are perhaps not fit for purpose.
Any thoughts? Any guide to how I should be installing the connectors? Any thoughts as to better quality connectors?
That’s a really interesting and tricky issue with the RG6 connectors causing loss of MoCA connectivity. Here are a few things to consider:
Connector Quality: Sometimes, lower-quality or improperly installed RG6 compression connectors can cause signal loss or poor contact. Try using a different brand or redoing the compression carefully.
Cable Prep: Make sure the coax cable is properly stripped and the braid/shield isn’t touching the center conductor, which can cause shorts.
Connector Compatibility: Some MoCA devices are picky about the connector type—make sure you’re using connectors specifically rated for RG6 coax and MoCA frequencies.
Signal Loss: Adding connectors can introduce slight signal degradation; if your cable run is already marginal, it could push the signal below what the MoCA device needs.

Please try to connect MoCA adapter to 5268 directly.
Sure thing. Here's the concept.
Internet > AT&T 5268 ac wireless gateway (with switch)> TP Link Dumb Switch > GoCoax device1 > RG6 cable > GoCoax device2 > TP Link Dumb Switch > connected devices
Like I said, as long as I don't put a RG6 connector on the RG6 cable into GoCoax device1, everything works as expected.
Should the GoCoax device be plugged directly into the switch on the 5268 ac?
Hi, The issue is not related to the RG6 connectors. It should be related to your network diagram.
Could you share your network diagram?
