Connecting an LG TV to the Internet via Wi-Fi: A Complete Guide with Troubleshooting

Modern televisions LG with function Smart TV provide access to streaming services, YouTube, browsers, and even cloud gaming—but only with a stable internet connection. Most models (starting with 2018) are equipped with a built-in Wi-Fi moduleHowever, even with this feature, users still encounter difficulties: the TV can't find the network, constantly drops the connection, or requires additional router settings. In this article, we'll cover all connection methods—from basic setup to troubleshooting rare errors not covered in the official manuals.

It is important to understand that the connection algorithm may differ depending on TV series (LG OLED C2, NanoCell 86, QNED 90 etc.), firmware versions webOS (from 3.0 to 23) and router type. We'll focus on the general steps, but we'll also point out the nuances for specific models. If your TV was manufactured before 2016, most likely, an external one will be required Wi-Fi adapter — We'll tell you about that too.

Before you begin, check two key points: 1) Make sure your router is broadcasting a network within the range 2.4 GHz (most old TVs don't support it) 5 GHz). 2) Disable the function on your router WPA3 (if activated) - many models LG to 2022 are incompatible with this security protocol.

1. Checking the compatibility of your LG TV with Wi-Fi

Not all TVs LG support wireless connectivity out of the box. To avoid wasting time, first determine whether your model has built-in Wi-Fi moduleThis can be done in three ways:

• 🔍 By TV model: Find the sticker on the back panel with the part number (for example, OLED55C1RLA) and check the specifications on the official website LGModels with the letter N at the end (for example, 43UN70006LB) are usually equipped with Wi-Fi.
• 📋 Via the menu: go to Settings → All settings → Network → Network statusIf there is a point Wi-Fi, the module is present.
• 🔌 By connectors: Look for a port on the back panel LAN (Ethernet) - its presence indirectly indicates support for wireless networks (but does not guarantee it!).

If your TV was manufactured before 2016 (for example, series LB650V or LF630V), most likely there is no Wi-Fi. In this case, you will need external USB adapter with support LG Smart TVThe company officially recommends adapters. LG AN-WF100 (for models 2012–2015) or AN-WF500 (For 2016–2017). Alternative adapters (eg, TP-Link TL-WN725N) may not work due to the lack of drivers in webOS.

⚠️ Attention: Televisions LG With NetCast (and not webOS) do not support modern Wi-Fi adapters. They can only connect to the internet via an Ethernet cable.

How do I find out the webOS version on my LG TV?

Go to Settings → All settings → General → About TV → TV informationThe webOS version is indicated in the "Software version" line (e.g. 05.30.45 (corresponds to webOS 5.3).

2. Preparing the router for connecting the TV

Connection problems in 70% of cases are not related to the TV, but to incorrect router settingsBefore setting up your TV, optimize your network:

• 📶 Frequency range: switch the router to mode 2.4 GHz (even if he supports 5 GHz). To do this, find the section in the router's admin panel Wireless Settings and select 802.11 b/g/n.
• 🔒 Security type: install WPA2-PSK (AES)Protocol WPA3 not supported by TVs LG older 2022, A WEP unsafe.
• 📡 Wi-Fi channel: manually select a channel from 1 to 11 (automatic selection may cause interruptions). To check channel load, use the app Wi-Fi Analyzer (Android).
• 🔄 Opening hours: disable the function 802.11r (Fast Roaming) - it conflicts with the connection algorithms webOS.

If your router supports guest network, create a separate access point specifically for the TV with simplified security settings. This will help avoid conflicts with other devices (for example, smartphones on Wi-Fi 6).

⚠️ Attention: If your router uses double NAT (for example, when connecting via a provider modem), the TV may not receive an IP address. Solution: put the modem in Bridge or disable DHCP on one of the devices.

3. Step-by-step instructions: connecting to Wi-Fi via the TV menu

Once the router is configured, we move on to connecting the TV. The interface may vary slightly depending on the version. webOS, but the general logic remains:

1. Open Settings: press the button Settings (gear) on the remote control or button Home (home) → select All settings (icon with three dots).
2. Go to the network section: select Net → Connecting to a Wi-Fi network.
3. Select network: Find your network in the list of available networks (if it is not there, click Refresh the list).
4. Enter password: Use the on-screen keyboard. For convenience, connect Bluetooth keyboard or use the app LG TV Plus on a smartphone.
5. Confirm connection: After entering the password, the TV will check the connection. If an error occurs, press Additional settings and select Connect despite errors.

If the TV asks static IP, but you don't know the parameters, go back to the router settings and turn it on DHCP (See table above). In rare cases, manual DNS entry may be required—use public servers. 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare).

The 2.4 GHz range on the router has been checked

WPA3 is disabled (WPA2 is used)

The TV is within a 5 meter radius of the router.
