Check the television's user manual or the manufacturer's website to check whether it has Wi-Fi enabled. If a television is a "Smart TV," it implies that it has Wi-Fi enabled. These televisions connect to home routers to receive data from the Internet.
Navigate to the connectivity features of the settings menu of the TV to check whether the TV is Wi-Fi ready or if it has built-in Wi-Fi connectivity. A Wi-Fi ready TV prompts you to connect an external adapter to it. If the TV has a built-in Wi-Fi connector, it scans available networks and prompts you to connect to one.
