What is the point in the Ethernet port on the back of the X1 TV box?

I have the X1 TV box connected with my current xfinity wifi but I want to hardwire the connection to have it stay stable. Even though the network menu says there's an option for wired connection it doesn't register the wired connection whatsoever. I want to know if the ethernet port on the back of the box is to receive a connection or give a connection.

only the xi5/xi6 can be connected via ethernet.

I have almost the same question, the TV picture was freezing, pixelated.  I also have a FireTV on that TV.  When viewing TV from that Fire stick, no more frozen picture, so the problem can't be just a wifi issue, the issue must be in the Xi set top box.  I was able to connect the main set top box to the Xi6 via ethernet, no more freezing picture.  But like the other commentor, my Xfinity app only shows that set top box recognizing the wifi signal.  How do I know the set top box is really receiving a hard wire signal?  BTW, my download speeds all over the house are up since hardwiring the set top box.  

I have almost the same question.  I have a main DVR  set top box in the basement connected to an XB7 gateway.  I have an Xi 6 set top box in the house main level.  I was getting frozen, pixelated picture from the xi box.  That TV also has a FireStick connected.  When viewing from the FireStick, no more frozen picture, which tells me that the wifi is not the cause of the frozen picture, the issue must be in the xi box.  I was able to connect the xi6 box to the main box via ethernet cable, now no more frozen picture.  Also, wifi download speeds are up all over the house.  I attribute this to taking a load off the broadband by hardwiring the Xi6 box.  Maybe I'm wrong on those assumptions.  Also, the Xfinity app will only show the Xi6 box to be connected via wifi.  How do I know if the ethernet connection is working? 

You have two different sources that aren’t comparable. Not only does the xi6 need to communicate with the xb7, the xb7 and the main box also have to communicate. If you are having problems, try resetting all 3. Did you mean it’s hardwired to the xb7?

The Xi6 is hardwired to the main set top box.  Wrong source?  I was experimenting since it's nearly impossible to get tech support any other way, chat is useless.  Help me out here.  At one point the app indicated that the xi6 box was connected to ethernet but has since shown as a disconnected device, strange.  The main box has always been connected to XB7 via coax.  I thought that the best connection to the Xi6 was to connect it to the main box.

The main box and xb7 are both connected independently via coax and use moca to communicate and then the xb7 communicates with the xb7. There is no Ethernet signal out of the main box for the xi6 to use, it should be hardwired to the xb7 or use a wireless signal
