Connecting Smart TV to internet through cable box?

[DebraF]

Hi, how do I connect my new 40K UHD Smart TV to the internet using my cable box! And what kind of cable do I need? My computer is already connected to the modem via Ethernet cable. I want to be able to stream. Thank you, Debra

If your modem has only 1 ethernet port then you REALLY need a router. It will provide security for your devices and provide multiple ethernet ports plus WIFI.
Even if your cable box uses ethernet for some functions, I don't know of any that will work as a bridge and allow you to connect a smart TV via an ethernet cable. Most smart TVs are WIFI enabled. Do you not have WIFI?

You don't mean the cable box, you mean the modem.

Cable box = gives you TV.
Modem = gives you Internet.

If you paid for both then you have the 2 boxes.

To clarify you can't connect the TV to the internet through the cable box.
You will either need to use Wifi or run an ethernet cable to the router (same as your computer). Wired connection is best if you can do it.
