How to Share Internet to a TV with a Wired Connection: 5 Proven Methods

Modern Smart TVs require a stable internet connection to watch online movies, YouTube, or update firmware. But what if your TV only has a wired Internet (Ethernet), but the Wi-Fi module is missing or not working properly? Or what if you need to share the internet from a computer with a direct cable connection? There are solutions—and several, in fact.

Many users mistakenly believe that a router is required to distribute Wi-Fi to a TV. In fact, you can do without one: use a laptop, smartphone, or a special adapter. The main thing is to set up the network correctly and avoid common mistakes that prevent the TV from detecting the signal. In this article, we'll cover these steps. 5 working methods, including nuances for different TV models (Samsung, LG, Sony Bravia and others), and we will also indicate which method is the fastest and most reliable.

⚠️ Important: If your TV was manufactured before 2015, check the technical specifications to see if it has a Wi-Fi module. Some older models (e.g., Samsung Series 5 2013 or LG 42LA620V) only support wired connections and will not be able to connect to Wi-Fi even via an adapter.
