Fios in bridge mode Orbi issue with Moca adapter

[rchilumula]

I have the Fios router connected in bridge mode which then connects to my Orbi. This is on my first floor and everything has been working fine. I decided to get a moca adapter to hard wire my upstairs PC. I purchased the Actiontec ECB6250 and connected it to the wall coax upstairs. It provides a signal and my PC works, but as soon as I do this, my Orbi wifi does down. If I unplug the Orbi and replug then the wifi starts but my moca adapter does not produce a signal. It is almost like only one of them can work at a time, as though they are competing to control the network. What am I doing wrong ?

This sounds like an IP conflict. You can try to change the Orbi to a different static IP address, let's see what happens.
