MoCA Adapter Not Sending Internet

Just bought some ScreenBeam (ECB7250) MoCA adapters to get Ethernet running to my office. We have an xFi Gateway XB8 (Technicolor CGM4981) with MoCA enabled. All splitters have been upgraded to allow up to 1675hz. POE filter installed from street line into first 3-way splitter that goes to master bedroom, basement, and office. Master bedroom is just a cable box. Gateway is in the basement, which has a splitter to run to the Gateway and a cable box. I had a 3-way splitter there as well to install one of the MoCA adapters based on its instructions. After setting up that adapter, I setup the other adapter in the office. At this time, the WiFi stopped working and so did Ethernet. I did some more research and it sounds like since the Gateway supports MoCA, you only need a MoCA Adapter where you need Internet (i.e., my office). I removed the adapter in the basement and kept the one in the office. While my Gateway setup page (10.0.0.1) shows the MoCA Adapter as a connected device and in general says MoCA is enabled (both cable boxes also show they are MoCA connected), I am not getting internet out of the Ethernet port of the MoCA Adapter in my office. What am I missing?
