How to Connect a TV to the Internet via a Router: A Complete Guide (2026)

Modern TVs without internet access are like smartphones without a SIM card: they work, but lose half their functionality. Online cinemas, YouTube, games, firmware updates, and even voice assistants require a stable connection. But how do you properly connect your TV to the internet via a home router if the model Samsung, LG, Sony Bravia or Xiaomi Connect differently? This article will cover all the working methods—from basic Wi-Fi to hidden features like WPS And bridge mode, and will also help avoid typical errors that cause TV to not see the network.

We will look at not only the standard methods (via WPS or settings menu), but also rare tricks - for example, how to make an old 2015 TV work with a modern one Wi-Fi 6, or why some routers TP-Link And ASUS Blocking Smart TV connections. We'll cover diagnostics separately: what to do if the network indicator on your TV is blinking but there's no connection, or why the internet speed on your TV is 10 times slower than on your laptop. All instructions apply to routers with firmware. DD-WRT, OpenWRT and standard firmware from the manufacturer.

1. Preparing the router: why your TV might not connect to Wi-Fi

Before setting up the TV itself, check your router—in 60% of cases, the problem lies with it. Modern Smart TVs have strict network requirements:

• 🔄 Wi-Fi operating mode: TVs older than 2018 often do not support 802.11ax (Wi-Fi 6). If the router only operates in this mode, the TV simply won't see the network.
• 🔒 Encryption type: obsolete WEP or new WPA3 may cause errors. Optimal WPA2-PSK (AES).
• 📡 Broadcast channelAutomatic channel selection (Auto) sometimes causes conflicts. For 2.4 GHz, it's better to manually select channels 1, 6, or 11.
• 🚫 MAC address filtering: If enabled, the TV will be blocked until you add its MAC to the whitelist.

How to check your router settings:

1. Open your router's control panel (usually at 192.168.0.1 or 192.168.1.1).
2. Go to the section Wireless Settings (or Wireless mode).
3. Make sure that:

⚠️ Attention: If you have a dual-band router (2.4 + 5 GHz), give the networks different names (For example, MyWiFi_2G And MyWiFi_5G). Many TVs do not automatically switch between bands and will only cling to 2.4 GHz, even if 5 GHz is more stable.

2. Method 1: Connecting via Wi-Fi through the TV menu (the easiest)

This is a basic method that works on 90% of Smart TVs. The instructions are universal for Samsung Tizen, LG webOS, Android TV (Sony, Philips, Xiaomi) and even for older models with Opera TVThe main requirement is that the TV must support Wi-Fi (check the model's specifications).

Step-by-step instructions:

1. Turn on the TV and take the remote control.
2. Click the button Home (or Menu, Settings — depends on the model).
3. Go to the section Settings → Network → Network settings (on LG: All Settings → Network → Wi-Fi Connection).
4. Select your network from the list. If there is no network:

Update your TV's firmware

Reboot your router

Check if the SSID is hidden in the router settings.

Make sure your TV and router are operating in the same band (2.4 or 5 GHz)

Try connecting to the network from another device (phone, laptop)-->

After selecting the network, enter the password. There are some nuances here:

• 🔐 On some TVs (for example, Samsung QLED 2020-2022) The password entry keyboard appears only after you click on the input field - take your time, wait for it to load.
• 📱 If your password is long, enter it first in your smartphone's notes and then transfer it to your TV to avoid mistakes.
• ⚙️ On Android TV (Sony, Philips) You may need to confirm the connection via your Google account.

After a successful connection, the TV usually prompts you to update the firmware - don't refuseThis will fix any potential network issues. If the connection is established, but the internet isn't working:

• Check if it is enabled on the router parental control or MAC filtering.
• Make sure that the TV is not installed VPN (sometimes it blocks access).
• Restart your TV (unplug it from the power outlet for 30 seconds).

3. Method 2: Connect via WPS (if you don’t want to enter a password)

Technology WPS (Wi-Fi Protected Setup) allows you to connect your device to your router without entering a password—just press a button on the router and confirm the connection on your TV. This is convenient if:

• 🔑 You forgot your Wi-Fi password.
• 📺 The TV does not have a keyboard for entering complex passwords (relevant for older models).
• ⚡ Need to quickly connect a guest TV (for example, in a hotel).

How does this work:

1. Make sure WPS is enabled on your router. To do this:

Go to your router's control panel → Wireless → WPS → Enable
On some models (eg, ASUS RT-AX88U) WPS is enabled by a physical button on the case.

2. On your TV, go to Settings → Network → WPS (on Samsung it could be Advanced Settings → WPS-PBC).
3. Press "Connect" or "Start WPS" on your TV, then within 2 minutes press the WPS button on your router (usually labeled or flashing blue).

If the connection is not established:

• 🔄 Repeat the process - sometimes it doesn't work the first time.
• ⏱️ Make sure the WPS timer on your router has not expired (usually 120 seconds).
• 🚫 Check if WPS is disabled in your router's security settings (some firmware versions block it by default).

⚠️ Attention: WPS is considered insecure—attackers can guess the PIN code within a few hours. After connecting the TV disable WPS in the router settings if you don't plan to use it.

What to do if WPS doesn't work on your TV LG OLED C1 and newer?

On TVs LG In 2021 and later, WPS is disabled by default due to Wi-Fi Alliance certification issues. To enable it, you need to:

1. Log in Settings → General → About TV → Software Information.

2. Press the LG logo 5 times in a row to open the service menu.

3. Go to WPS Settings and activate the option.

⚠️ This is an unofficial method and may void your warranty!

4. Method 3: Connecting via cable (LAN) - for maximum stability

If your TV supports Ethernet (RJ-45 connector), and the router is located nearby - this is the best option. Advantages:

• 📶 No interference or interruptions (like with Wi-Fi).
• 🚀 Speed ​​up to 1 Gbps (relevant for 4K content).
• 🔒 Safer - no one will intercept your traffic.

How to connect:

1. Buy a cable Cat 5e or Cat 6 the required length (up to 100 meters without loss).
2. Insert one end into the port LAN on the router, the other one - in the connector Ethernet on TV.
3. On TV, select Settings → Network → Cable connection.
4. If the connection is not established automatically, check:

• 🔌 The cable must be crimped correctly (try another cable).
• 🔄 Restart your router and TV.
• 📡 Make sure that the router is enabled DHCP (automatic IP distribution).

If the cable internet doesn't work, but Wi-Fi works:

• Check if the port is broken LAN on the TV (try a different port on the router).
• Set the IP manually: in the TV network settings, specify:

IP: 192.168.1.100 (or another free one in your network)
Mask: 255.255.255.0
Gateway: 192.168.1.1 (your router's address)
DNS: 8.8.8.8

⚠️ Attention: On some TVs Sony Bravia 2019-2020, when connecting via cable, you may need to disable IPv6 in the network settings, otherwise the Internet will not work.

5. Method 4: Wireless connection via Miracast/Wi-Fi Direct (for streaming from a phone)

If you need not just to connect the Internet to your TV, but mirror your smartphone or laptop screen (for example, to show presentations or games), use technology Miracast or Wi-Fi DirectThey work without a router, creating a direct connection between devices, but require support from the TV.

How to check compatibility:

• On Android TV (Sony, Philips, Xiaomi) Miracast is supported by default.
• On Samsung look for the function Screen Mirroring (or Smart View).
• On LG this is called LG Screen Share.
• 🍎 For iPhone needed Apple TV or a TV with support AirPlay 2 (For example, Samsung QLED 2021+).

Instructions for Android:

1. Turn on the TV Miracast or Screen Mirroring (usually in Settings → Connections → Screen Mirroring).
2. On your smartphone, open Settings → Connections → Screen Sharing (on Xiaomi: Screen mirroring).
3. Select your TV from the list of available devices.
4. Confirm the connection on both devices.

If the connection drops or slows down:

• 📶 Make sure your router is within range 5 GHz (2.4GHz is too slow for Miracast).
• 🔄 Disconnect other devices from Wi-Fi as they may cause interference.
• 🖥️ On a laptop with Windows 10/11, use the combination Win + K for quick connection.

For iPhone:

1. Make sure your TV and iPhone are connected to the same Wi-Fi network.
2. Open Control center (swipe down from the top right corner).
3. Click Screen mirroring and select TV.

⚠️ Attention: When using Miracast, your TV will consume 20-30% more power than in standard mode. If you plan on using it for extended periods (such as a TV marathon), plug it into a power outlet rather than running it on battery power (this applies to portable models).

6. Method 5: Connecting via DLNA (to view files from a PC)

If you need not only to get the Internet, but also stream movies, music, or photos from computer to TV, use the protocol DLNAIt allows you to stream content wirelessly, but requires:

• 🖥️ A computer or laptop with an enabled DLNA server.
• 📺 TV with DLNA support (almost all Smart TVs after 2014).
• 🌐 Both devices must be on the same network (via the same router).

How to set up:

On Windows 10/11:

1. Open Settings → Network & Internet → Sharing options.
2. Turn on Media sharing and select folders to share.
3. On your TV, open the app DLNA, Media Player or Photo/Video (on Samsung This Smart Hub → Multimedia).
4. Select your computer from the list of devices.

On macOS:

1. Open System Preferences → Sharing.
2. Turn on Media sharing.
3. On your TV, use the built-in media player (for example, VLC on Android TV).

If the TV does not see the computer:

• 🔥 Check that firewall does not block DLNA (add an exception for Windows Media Player Network Sharing Service).
• 🔄 Restart your router—sometimes it doesn't pass multimedia traffic.
• 📂 Make sure the folders containing the files are marked as General.

For convenience, you can use third-party DLNA servers:

• 🎵 Plex — to organize a complete media library.
• 📽️ Kodi - if you need to play rare video formats.
• 🖥️ Serviio — for transcoding files on the fly.

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

If none of the above worked, try this checklist:

If the problem persists, try reset network settings on TV:

1. On Samsung: Settings → General → Reset → Reset network settings.
2. On LG: All settings → Network → Additional settings → Reset Wi-Fi.
3. On Android TV: Settings → Network & Internet → Advanced → Reset Wi-Fi.

Critical error: on TVs Sony Bravia From 2017 to 2019, resetting the network sometimes resets app licenses (Netflix, YouTube). Before resetting, write down your Google or Sony Entertainment Network account information.

8. Additional tips for advanced users

If standard methods don't help, try these techniques:

• 🔧 Bridge modeIf you have two routers, connect the second one in bridge mode and connect the TV to it via cable. This will eliminate Wi-Fi interference.
• 📡 Guest network: some TVs (especially Xiaomi) work better on the router's guest network. Create a separate network with a simple password and connect the TV to it.
• 🔄 Router firmware: if you have a router TP-Link or ASUS, try installing alternative firmware (DD-WRT, OpenWRT) - it provides better support for older devices.
• 🛠️ Static IP: If the router frequently changes the TV's IP address, set a static address in the DHCP settings.

For owners NVIDIA Shield TV or Amazon Fire TV Stick:

• These devices can be connected to the TV via HDMI and use them as an intermediary for internet access. Simply connect them to Wi-Fi and then use the built-in apps.
• Advantage: Fire TV Stick supports Wi-Fi 6 and handles streaming video better than the built-in modules found in many TVs.

If you use Mesh system (For example, Google Nest Wi-Fi or TP-Link Deco):

• Make sure your TV is connected to the main unit and not the satellite - this will improve stability.
• In the Mesh settings, disable it. Band Steering (automatic switching between 2.4 and 5 GHz) - some TVs do not work well with it.

⚠️ Attention: Configuring alternative firmware (DD-WRT, OpenWRT) may void your router's warranty. Before updating the firmware, back up your current settings.
