The reason TVS have cable connections and no wifi is because they are designed to receive broadcast TV signals, not Internet access. Moreover, connecting to a wired network can provide a more stable and fast network connection, which can better support the playback of high-definition video and other streaming content. In addition, most TVS have smart TV capabilities that allow you to use wifi networks by connecting to other devices, such as game consoles, TV boxes, or smartphones. To sum up, although the TV does not have built-in wifi, using a wired Internet connection is a more practical and stable choice.
More than 1000 TVS basically have wifi modules, the following is not necessarily, you have to see clearly when you buy.
