I used a 3-way coax splitter to connect the wall, cable modem and moca adapter, then connected the moca adapter and router with Ethernet. Is this setup correct?
I have a total of 4 google mesh pucks in the house. One of the puck is in a room with coax outlet, but the other 2 locations does not have a coax outlet.
As soon as I connected the moca adapter, I lost internet in the entire house. Once I reversed the connection (not using the moca adapter), WiFi is working again.
The setup is correct. Maybe the MoCA and DOCSIS have some interference. Could you share the model number of your cable modem/routet?
