Can i use the ethernet port on my AX014ANM cable set top 4k box to give my TV internet?

Nope, it is disabled

“Future use”, they also license the boxes for use around the world. Use Xfi pods or a Wi-Fi extender to get an internet signal to your tv, that’s what they’re made for. X1 boxes have been around for over a decade, if they were going to use that port it would’ve been a long time ago

Thx for the quick reply.

Any idea why Comcast disables it? It would make a lot of sense to enable it, make customers happy, etc.
