Modern TVs with support Smart TV become full-fledged entertainment centers only after connecting to the internet. Without Wi-Fi, you won't be able to watch YouTube, Netflix, to use IVI or install apps from the store. But what if the TV won't connect to the network, constantly asks for a password, or doesn't see any available hotspots at all?

This article will help you figure out how to properly enable internet access on your TV via Wi-Fi, set up your network, and troubleshoot common errors. We'll cover universal solutions for all brands (Samsung, LG, Sony, Xiaomi and others), and we will also give advice on optimizing the connection for stable video viewing in 4K And 8K.

If your TV was released before 2015, it may not support modern Wi-Fi standards (e.g. 802.11ac or Wi-Fi 6). In this case, you will need to use an adapter or a wired connection via Ethernet.

1. Preparing your TV for Wi-Fi connection

Before setting up the internet, make sure your TV supports wireless networks. Older models may not have a built-in Wi-Fi module; in this case, you'll need an external adapter (e.g., USB Wi-Fi dongle For LG or Samsung).

To check if a module is available:

• 📺 Take a look at technical specifications models on the manufacturer's website (look for lines like Wi-Fi Direct, Dual Band Wi-Fi or 802.11n/ac).
• 🔍 Look at the back panel of the TV - if there is a connector for an external antenna or an inscription Wi-Fi, the module is built-in.
• 📋 Check the settings menu: go to Network → Network SettingsIf there is a point there Wireless network, which means Wi-Fi is supported.

Important: some budget models (for example, TCL 32S5200 or Hisense A4K) may have Wi-Fi only in modifications with a set-top box Smart in the title. Check this before purchasing!

⚠️ Attention: If the TV was previously connected to a different network (for example, in a store or with a previous owner), reset the network settings via Settings → Support → ResetThis will avoid conflicts when connecting again.

2. Step-by-step instructions: how to connect your TV to Wi-Fi

The connection algorithm is almost the same for everyone Smart TV, but the menu item names may differ. We'll look at a universal method and then point out the specifics for popular brands.

Select your access point from the list

Enter your Wi-Fi password (case sensitive!)

Confirm the connection and wait for the network to be checked.

Please reboot your TV to apply the settings-->

More details about each step:

1. Enter the settings menu. Press the button on the remote control Home (or Menu, Settings — depends on the model). In the menu that opens, find the icon ⚙ Settings (usually in the upper right corner).
2. Network selection. Go to the section Network → Network Settings (at Sony Bravia it could be Network Settings → Set up a network connection). Select Wireless network (Wi-Fi).
3. Search for access points. The TV will begin scanning. If your network is not displayed, press Refresh the list or check if the SSID is hidden in the router settings.
4. Enter password. Select your network from the list and enter the password. Please note: for security reasons, your TV screen may not display the character input. Use the keys ↑↓←→ on the remote control to select letters.
5. Checking the connection. Once connected, the TV will check for internet access. If an error occurs, try manually entering it. IP address or DNS (more on this below).

If the TV asks security type (For example, WPA2-PSK), select the same one as in the router settings. You can find it in the router's web interface (usually at 192.168.0.1 or 192.168.1.1).

3. Connection features for different brands

Manufacturers frequently change their menu interfaces, so instructions may vary. Below are the current paths for popular brands (as of 2026).

Televisions Samsung series QLED 2021–2023 may block connections to public networks (for example, in hotels) due to security policies. In this case, use guest mode on a router or mobile hotspot.

⚠️ Attention: On TVs LG With webOS There may be no support for versions prior to 5.0. WPA3If the router only works in this standard, change the security type to WPA2-PSK.

4. Troubleshooting: TV won't connect to Wi-Fi

If after entering the password an error appears ("Unable to connect", "Authentication Error" or "Weak signal"), try the following methods:

• 🔄 Restart your router and TV. Unplug the router for 30 seconds, then plug it back in. Restart the TV using the menu or the power button on the TV.
• 📶 Check the coverage area. If the signal is weak (1-2 bars on the indicator), move the router closer or use repeater (signal amplifier).
• 🔒 Change the security type. Temporarily disable it in your router settings. WPA3 and leave only WPA2-PSK. Also check if the filter is enabled. MAC address.
• 📡 Change the Wi-Fi channel. In urban areas, channels 2.4 GHz are often overloaded. In manual mode, select a channel 1, 6 or 11 (they intersect less).
• 🔧 Update your TV firmware. Outdated software may not support new Wi-Fi standards. Updating resolves the issue in 60% of cases.

If the TV sees the network but does not connect, try forget the network (delete it from saved) and enter the password again. Samsung this is done through Settings → General → Manage Networks, on LG - through Settings → Network → Remove network.

What should I do if my TV doesn't detect Wi-Fi at all?

If the list of networks is empty, the problem may be hardware:

1. There is no Wi-Fi module — check the model specifications.

2. The module is broken — repairs required (antenna or chip replacement).

3. Airplane mode is enabled - disable it in the settings (Settings → Airplane Mode).

4. Incompatible standard - if the router only works on 5 GHz, and the TV only supports 2.4 GHz, change the router settings.

5. Setting up the Internet via cable (Ethernet)

If Wi-Fi is unstable or unavailable, use a wired connection. To do this:

1. Connect network cable (twisted pair) from the router to the port LAN on TV.
2. Go to Settings → Network → Cable connection.
3. Select Automatic IP acquisition (DHCP). If the Internet does not work, please indicate IP, Gateway And DNS manually (they can be found in the router settings).
4. Save the settings and restart the TV.

A wired connection offers several advantages:

• 🚀 Higher speed (to 1 Gbps against 300–600 Mbps via Wi-Fi).
• 📺 Stability - no delays or interruptions when viewing 4K HDR.
• 🔌 Less interference - the cable connection is not affected by other devices or walls.

If the TV does not have a port LAN (for example, in ultra-thin models Samsung The Frame), use USB-Ethernet adapter (supported by the majority Android TV).

6. Optimize Wi-Fi for stable video viewing

Even if your TV is connected to the network, it doesn't guarantee comfortable viewing. To avoid video stuttering and freezing:

• 📊 Check your internet speed. For Full HD no less is needed 10 Mbps, For 4K — 25 Mbps, For 8K — 50+ MbpsYou can check your speed through the app. Speedtest on TV or smartphone.
• 🔄 Disable background updates. In the TV settings (Settings → Support → Software Update) Disable automatic update checking, as it can slow down streaming video.
• 📡 Configure Quality of Service (QoS) on your router. Prioritize your TV's traffic so that other devices (smartphones, laptops) don't hog your speed.
• 🔌 Use 5 GHz for 4K. Range 5 GHz It's less congested and provides higher speeds, but has a shorter range. If your TV is far from your router, stay on 2.4 GHz.

If the image is choppy or constantly buffering, try:

1. Reduce the video quality in the application settings (for example, in YouTube select 1080p instead of 4K).
2. Connect the TV to the router via Powerline adapter (Internet transmission via electrical wiring).
3. Disable VPN or proxy if used.

⚠️ Attention: Some providers (eg Rostelecom or Beeline) speed limits for video services are applied during peak hours (evenings). If slowdowns occur regularly at the same time, please contact support to check your plan.

7. Alternative ways to connect your TV to the Internet

If Wi-Fi and cable are unavailable, there are a few other options:

• 📱 Mobile hotspot. Share the Internet from your smartphone (Settings → Mobile Hotspot). The downside is limited traffic and rapid battery drain.
• 💻 USB modem. Connect your 4G/5G modem to your TV via USB port (does not work on all models, requires support) USB-tethering).
• 🖥️ DLNA or Miracast. Stream video from your computer or smartphone to your TV via a local network (without direct internet access).
• 🎮 Set-top boxes and media players. Use Apple TV, Nvidia Shield or Xiaomi Mi Box for internet access - they often work more reliably than built-in TV modules.

For Samsung And LG There are branded adapters for connecting to the mobile Internet (for example, LG AN-WF100). They allow you to use a SIM card directly, but are expensive and not supported by all models.
