I purchased two goCoax MOCA devices in December 2020. I connected one between my Verizon G3100 router and Verizon FIOS DVR, and the other to a spare bedroom's coax cable to a Roku device. Everything worked fine until about a week ago when suddenly all of the Verizon STBs boxes stopped receiving a TV picture.
Verizon did remote troubleshooting and determined my G3100 was not receiving a LAN connection. I removed the goCoax from the signal path and all Verizon STBs started working again. It appears the goCoax device was somehow interfering with the FIOS signal.
Any advice to help me resolve this issue would be greatly appreciated.
