In short, I cannot get the subject adapter to work even with multiple installation methods. I have an HDTV & STB in an upstairs bedroom that I would like to provde video and programming info via COAX to the STB and ethernet to the HDTV for Smart TV functions using the subject device. When the coax is directly connected to the STB, there is no problem with the STB obtaining an IP address and displaying the programming guide. I installed a single subject adapter since it was my understanding that the G1100 router negated the need for a second Actiontec device in the signal stream. WIth this installation, I get video (which I assume is via QAM) but I lose an IP address and have no programming guide, nor do I see ehternet on the HDTV. The STB is a Motorola HD QIP 7100 1. I tried a reboot after installation of both the router and the STB, but no change.
I then tried installing two of these adapters and removed the COAX connection to the G1100 (see picture above). This was the new installation for the home closest to the ONT: ONT->POE Filter->4-way splitter->ECB6200 Coax In->ECB6200 Ehternet Out->G1100 LAN Port. I left the adapter in the upstairs bedroom installed as per manufacturer instructions and nothing changed. I am not really sure where to go from here. I am wondering if there is a compatibility issue with the equipment I am using and the Actiontec device. Looking for advice on where to go from here.
