Create an open Xfinity Wi-Fi network, as well as an AT&T one. See if the TV connects to them.
This is probably obvious to most people, but I will mention just the same: do not install the antenna that the TV comes with.

Wifi antennas would typically be internal and unrelated to the one F-Type coaxial connector one would typically think of as the "antenna" input.
Can't really stop the internal module from scanning and connecting to open access points unless you control the software.
