MOCA works on coax outlet, but not Xfinity Gateway.
I currently have my Xfinity Gateway (XB8) on the 1st floor of my house. I also have a separate router on the 3rd floor, hooked up to the internet via a MOCA adapter. I used to have the XB8 Gateway connected directly to the cable for internet service and MOCA setup with the existing coax of my house, but recently I tried using the MOCA built into the XB8. It works fine, though the actual speed is slower than the other setup was, since the XB8 is only MOCA 2 and not 2.5 like my MOCA adapters. Setup is service cable for internet going to a POE filter, then to the input of a MOCA splitter. The 2 outputs go to the coax wall outlet on my 1st floor near the XB8 and the coax wall outlet on 3rd floor near router.
The router is showing it's age and drops the internet connection, wired and wifi, when my kids are gaming online. I assumed that I would be able to just flip flop the router and the XB8 Gateway. However, when I connect the Gateway to the 3rd floor coax outlet, it never connects to Xfinity, I just get the blinking orange light. I tried doing a reset, nothing. I tried doing a factory reset, nothing. I disconnected the service line from the POE filter and MOCA splitter and did a direct connection to the coax cable that feeds to the 3rd floor, did another factory reset. Still nothing. I know the cable is connected because I can have 2 MOCA adapaters recognize each other (the moca light is lit). Can a splitter that might be in the walls affect the Gateway from receiving a signal from Xfinity, but not have an effect on MOCA?

As someone that spends most of their free time at home gaming online, I definitely know the importance of having that connection be as close as possible duanecole79! If you're not seeing anything beyond the blinking orange light from the Xfinity modem after moving it to the new COAX outlet, the simple answer is that the specific outlet may not be active for the Xfinity service.
Have you had Xfinity equipment hooked to that COAX outlet at any point previously?

UPDATE
Been busy, but the problem is fixed. There is a "crawl space" on the 3rd floor that runs to each side of the house. I went in there and followed the coax cable that connects to the outlet I was using on the 3rd floor. It was running parallel with several electrical wires for about 10 feet. I moved it away from them, as much as I could, all the cable/wires run down through the 2nd and 1st floor to under the house. However, there is about 4 feet of coax that I can not see that runs into the wall where the outlet is at. I believe the coax cable is probably running parallel with the electrical wiring there as well because I still can not get the XB8 to connect to the internet. If I bypass that outlet and just do a straight connection to the coax in the "crawl space", I can. There was another coax cable in the "crawl space" that runs the opposite way as the rest of the cables, through another room to the outside, down the side of the house, to under the house, but isn't connected to anything. I decided to connect the Xfinity feed line to it so I could just have a straight connection to the XB8 and just use my 2 MOCA adapters. Since the XB8 uses MOCA 2 and not 2.5. Still not able to use the coax outlet on the 3rd floor. The MOCA adapters can connect to each other, but there must be so much interference in that 4 feet of wall and the wiring, that it is what has been causing the secondary router to lose internet. So the router isn't going bad after all. I just installed a new coax outlet near the XB8 to run an ethernet cable to a MOCA adapter to connect to the 1st floor adapter.
