How to Share Internet from a Smart TV via Wi-Fi: 5 Effective Methods

Modern Smart TV — these are not just devices for watching movies, but also full-fledged multimedia centers with advanced network capabilities. Many users don't realize that their TV can be used as Wi-Fi hotspot, distributing internet to smartphones, laptops, or tablets. This is useful in situations where there is no router at hand and the only network connection is via Ethernet cable or USB modemFor example, in a hotel with wired internet or at a dacha with a 4G USB modem.

In this article we will look at all the possible ways to distribute Wi-Fi from TV — from standard menu functions to workarounds using additional equipment. It's important to understand that not all models support direct network sharing, but even then, there are alternatives. We tested the instructions on TVs. Samsung, LG, Sony Bravia, Xiaomi And Philips with current firmware versions.

Before you begin, please check: 1) Does your TV have a port? Ethernet (LAN) or connector for USB modem. 2) Does the firmware support the function? Mobile Hotspot (on some models Samsung Tizen And LG webOS). 3) Are there any restrictions from the provider (some operators block distribution through secondary devices).

1. Share Wi-Fi via the built-in Mobile Hotspot function (for supported models)

The easiest way is to use the built-in option Mobile Hotspot, which is available on some TVs Samsung (series QLED 2020+, Crystal UHD 2021+) And LG (models with webOS 5.0 and newer). This feature allows you to share the Internet via Wi-Fi if the TV is connected to the network via Ethernet or USB modem.

How to enable:

• 📺 Open Settings → Network → Mobile Hotspot (on Samsung) or Settings → General → Mobile Hotspot (on LG).
• 🔄 Turn on the switch Hotspot and set the network name (SSID) and password (minimum 8 characters).
• 🔗 Connect your TV to the Internet via LAN cable or USB modem (if mobile Internet is used).
• 📱 Find the created network on other devices and connect by entering the password.

Limitations of the method: — Does not work on all models (for example, on Sony Bravia And Philips (there is no such function). — The distribution speed is limited by the power of the TV's Wi-Fi module (usually up to 150–300 Mbps). — When using USB modem Additional APN (Access Point Name) configuration may be required.

⚠️ Attention: On TVs Samsung with firmware Tizen 5.5 and below the function Mobile Hotspot may be missing even in flagship models. Check the software version in Settings → Support → About TV.

2. Using an Ethernet cable and an external Wi-Fi adapter (universal method)

If your TV does not support direct Wi-Fi distribution, but it has a port Ethernet (LAN), you can connect an external one Wi-Fi router in bridge mode or USB adapter with SoftAP functionThis method works on any Smart TV, including older models.

You will need: — Ethernet cable (from provider or router). — Wi-Fi router with support for the mode WISP (Wireless ISP) or Client Mode (For example, TP-Link TL-WR840N, Asus RT-N12). — Or USB Wi-Fi adapter with support SoftAP (For example, Edimax EW-7811Un).

Step-by-step instructions for the router:

1. Connect the router to the TV via LAN cable (use port WAN on the router).
2. Go to the router's web interface (usually at 192.168.0.1 or 192.168.1.1).
3. In the section Opening hours select WISP or Client Mode.
4. Set up a network name (SSID) and a password for distributing Wi-Fi.
5. Save the settings and reboot the router.

For USB adapter: 1) Connect the adapter to the USB port of the TV (if OTG is supported). 2) Install the driver (manual download may be required via ADB). 3) Turn on the mode SoftAP via terminal (command:

netsh wlan set hostednetwork mode=allow ssid=MyTVHotspot key=12345678

).

3. Sharing the Internet from a TV via a USB modem (3G/4G)

If you have USB modem (for example, from MTS, Megaphone or Yota), it can be connected directly to a TV and share internet via Wi-Fi. This method is suitable for summer cottages, country houses, or trips where wired internet is not available.

What you need to do:

• 🔌 Insert the USB modem into the TV port (preferably using USB 3.0 for stability).
• 📶 Go to Settings → Network → Mobile network (on Samsung) or Settings → Network → USB Modem (on LG).
• 🔄 Turn on the option Use as a modem and wait until you connect to the operator's network.
• 🌐 Activate Mobile Hotspot (if any) or connect an external router to the TV via Ethernet for distributing Wi-Fi.

Possible problems and solutions:

• ❌ The modem is not detected: Check the compatibility of the modem model with your TV (for example, Huawei E3372 works with Samsung, A ZTE MF823 - No).
• ❌ No network connection: Make sure your SIM card is activated and has sufficient funds. Some TV models require manual entry. APN (parameters can be clarified with the operator).
• ❌ Slow internet: USB modems are speed limited 4G (up to 150 Mbps)To speed things up, disable background updates on your TV.

⚠️ Attention: Not all USB modems are compatible with TVs. For example, Samsung officially supports only models Huawei E3372, E3531 And ZTE MF831For others, it may be necessary to flash the modem to the mode NDIS.

4. Alternative method: distributing Wi-Fi from a TV via a smartphone (reverse tethering)

If your TV can't distribute Wi-Fi on its own, but you have a smartphone on Android or iPhone, can be used reverse tetheringThe essence of the method: the phone connects to the Internet via TV (via USB or Ethernet), and then distributes it via Wi-Fi to other devices.

Instructions for Android:

1. Connect your phone to your TV via USB cable (in mode USB tethering).
2. On TV in Settings → Network select USB tethering as a source of the Internet.
3. Turn on your phone Wi-Fi hotspot (Settings → Network & Internet → Access Point).
4. Connect other devices to the network that your phone is broadcasting.

For iPhone: 1) Connect iPhone to the TV through USB-Lightning cable or Ethernet adapter (For example, Apple USB-C to Ethernet). 2) On your TV, select USB or Ethernet as a source of the Internet. 3) On iPhone turn on Modem mode (Settings → Tethering) and distribute Wi-Fi.

Advantages of the method: — Powered by any Smart TV, even without support Mobile Hotspot. — Allows you to use 5G on a smartphone for distribution (if the TV does not support high-speed modems). — You can flexibly manage traffic through applications on your phone (for example, track data consumption).

Why doesn't reverse tethering work on some TVs?

On TVs Sony Bravia 2018–2019 years of production and some models Philips no support USB tethering at the software level. In this case, only connecting via Ethernet adapter for smartphone (for example, USB-C to Ethernet For Android or Lightning to Ethernet For iPhone).

5. Setting up Wi-Fi distribution via Ethernet and Powerline adapters

If your TV is connected to the internet via Ethernet, but is located far from other devices, you can use Powerline adapters (technology HomePlug AV). They transmit the internet signal through electrical wiring and then convert it into Wi-Fi.

How does this work:

1. Connect the first one Powerline adapter to the TV through Ethernet and plug it into the socket.
2. Connect the second adapter (with Wi-Fi support) to a power outlet in another room.
3. Set up a Wi-Fi network on the second adapter via the web interface or mobile app.
4. Connect devices to the created network.

Advantages of the method: — Stable signal without speed loss (up to 1 Gbps under ideal conditions). — There is no need to lay cables throughout the apartment. — Supports up to 16 devices on the same power grid.

Cons: — Depends on the quality of the electrical wiring (in older houses the speed may drop). — More expensive than a regular Wi-Fi router (a set of two adapters costs from 3 000 ₽).

6. Problems and errors when distributing Wi-Fi from a TV

Even with proper setup, glitches can still occur. Let's look at the most common errors and how to fix them.

Problem 1: The TV does not detect the USB modem.

• 🔹 Check if your modem model is supported (a list of compatible devices is usually included in the TV manual).
• 🔹 Try a different USB port (e.g. USB 3.0 instead of USB 2.0).
• 🔹 Update your TV firmware to the latest version.

Problem 2: Wi-Fi is available, but the Internet does not work.

• 🔹 Make sure your TV is turned on Internet access sharing (in network settings).
• 🔹 Check if your provider blocks data sharing (some operators prohibit the use of secondary devices).
