Can I connect an Xfinity TV box to my XFi Gateway via ethernet and receive cable programming

Hi, I have a room in my house that I'd like to put a TV in and have access to our Xfinity cable programming.  However, there is no existing coax. to that room.  But the room does have an ethernet port that is connected via switch to my coax connected Xfinity Gateway modem/router.  My question is can I hardwire connect an Xi6 TV box via that ethernet port to my gateway and get my cable programming?  I know the Xi6 is also Wifi enabled but I question the strength of my wifi signal in this particular basement room hence why I want to hardwire via ethernet.  Another user had a similar question in the forum about a year ago but responses were conflicting which is why I am asking again.
