1. Connecting via a network cable (Ethernet) is the most reliable method

If your TV is equipped with LAN port (usually located on the rear panel) is ideal for a stable internet connection without Wi-Fi. Cable connection speeds are always higher than wireless, and latency (ping) is minimal—critical for online gaming or 4K video.

You will need:

• 🔌 Twisted pair (cable Cat 5e or higher) - the length depends on the distance to the router.
• 📡 Router with a free LAN port (usually yellow).
• 🖥️ TV with a connector RJ-45 (most models Samsung QLED 2018+, LG OLED CX/C1, Sony Bravia X90J and newer ones are supported).

Step-by-step instructions:

1. Turn off your TV and router (this will reset the network settings cache).
2. Connect one end of the cable to the LAN port of the router and the other to the connector LAN on TV.
3. Turn on the router and wait until it is fully loaded (the indicators should be steadily lit).
4. Turn on your TV and go to Settings → Network → Network Connection (the path may differ depending on the model).
5. Select Wired connection and wait for automatic IP configuration (DHCP).

On some TVs (eg. LG webOS (until 2019) USB tethering only works after reset network settingsGo to . Settings → General → Reset → Reset network settings and try connecting again.

3. Using Powerline adapters – Internet via electrical wiring

If it is inconvenient to lay a cable from the router to the TV, Powerline adapters They transmit internet signals over existing electrical wiring. This is an ideal solution for multi-room apartments where Wi-Fi coverage is poor and running cables through the entire building is not an option.

How does this work:

• 🔌 Two adapters are connected to sockets: one next to the router, the second next to the TV.
• 📶 Data is transmitted over electrical wires at speeds up to 1200 Mbps (actual speed depends on the quality of the wiring).
• 🖥️ The TV is connected to the second adapter via Ethernet cable.

Step-by-step setup:

1. Plug the first adapter into a power outlet near the router and connect them patch cord (included in the kit).

4. On your TV, select Wired connection in the network settings.

Popular adapter models:

• 🔹 TP-Link TL-PA7010P KIT — a budget option with a pass-through socket.
• 🔹 Devolo Magic 2 Wi-Fi Next — supports both Ethernet and Wi-Fi.
• 🔹 Zyxel PLA5456 - high speed (up to 1300 Mbps) and stability.

⚠️ Note: In older homes with aluminum wiring, Powerline speeds can drop to 10–50 Mbps. Before purchasing, check the wiring quality or test adapters at a store with a return policy.

4. Configuring the router in bridge mode (WISP) for cable connection

If you have a second router (even an old one), you can use it as bridge To transmit internet to a TV via cable. This method is useful when the main router is located far away and running a long cable is inconvenient.

What you will need:

• 📡 Two routers (primary and secondary).
• 🔌 Network cable for connecting routers.
• 🖥️ TV with LAN port.

Instructions:

1. Plug the second router into a power outlet and connect it to the main router via LAN port (not WAN!).
2. Go to the web interface of the second router (usually at 192.168.0.1 or 192.168.1.1).
3. Find the mode in the settings Bridge or "WISP" (on TP-Link This Operation Mode → Range Extender).
4. Select the main router network and enter its password.
