Connecting a TV LG Smart TV Connecting to a wireless network is a challenge every homeowner faces after purchasing or moving. Despite the intuitive interface WebOS, the Wi-Fi setup process can be challenging, from lack of network visibility to authentication errors. This article covers all the steps, from basic setup to troubleshooting rare issues specific to certain models. LG OLED, NanoCell And QNED 2018–2026.

We will look at not only the standard path through the TV menu, but also alternative methods: connecting via WPS, setting up 5 GHz networks, and working with hidden SSIDs. Particular attention is paid to error diagnostics - from code 102 (problems with DHCP) to 203 (encryption incompatibility). If your LG If you're persistently unable to see the network or are losing connection, here you'll find proven solutions.

Important: The procedure may vary slightly depending on the version. WebOS (See compatibility table below). For models older than 2018 (e.g. LG UK6300) a firmware update may be required.

1. Preparing to connect: What to check before setting up Wi-Fi

Before you go to the TV menu, make sure the problem is not related to the environment. 50% connection errors are associated with external factors - from incorrect router settings to interference from neighboring networks.

Here is a checklist of mandatory checks:

The router is turned on and distributing Wi-Fi (the WLAN indicator is green/blue)

The TV is in a strong reception area (no further than 10 m from the router at 2.4 GHz)

The MAC address filter is disabled on the router (if enabled, add the TV's MAC address)

The network operates in mixed mode 802.11n/ac/ax (not only 802.11b)

The network password does not contain Cyrillic or special characters (for example, #$, %)

-->

If you are using a dual-band router (2.4 GHz + 5 GHz), please note:

• 📶 2.4 GHz — better through walls, but susceptible to interference from neighboring networks. Ideal for TVs in remote rooms.
• 🚀 5 GHz — higher speed and stability, but shorter range. Suitable if the TV is located near the router.
• ⚠️ Some models LG (For example, 43UN73006LB) do not support 5 GHz in earlier firmware versions.

TV MAC address This may be required to connect to the router. To find out:

1. Press on the remote control Settings (⚙) → All settings → General → About TV → TV information.
2. Find the line MAC address (Wi-Fi) - usually it is 12 characters in the format XX:XX:XX:XX:XX:XX.

2. Standard Wi-Fi connection via the LG Smart TV menu

This method works for 90% of users. The instructions are relevant for WebOS 4.0–23 (models from 2018 to 2026).

Steps to connect:

1. Turn on the TV and press the button Settings (⚙) on the remote control (or Home → Settings).
2. Go to the section Network → Connect to Wi-Fi.
3. Select your network from the list. If there is no network, click Refresh the list or Other networks (for hidden SSIDs).
4. Enter the password using the on-screen keyboard. For convenience, use the remote control. Magic Remote (cursor control).
5. Confirm the connection. The status should appear within 10-30 seconds. Connected.

What to do if WPS doesn't work?

If the TV does not find the router in WPS mode, check:

1. Is WPS enabled in the router settings (section Wi-Fi → WPS).

2. Does your LG model support WPS (some 2018–2019 TVs do not work).

3. Is there any interference from other devices (for example, a microwave or wireless headphones).

Connecting to a hidden network (hidden SSID)

If your router is not broadcasting the network name (hidden SSID), follow these steps:

1. From your TV's Wi-Fi menu, select Other networks or Add a network manually.
2. Enter the network name (SSID) exactly the same as in the router settings (case sensitive!).
3. Select the security type (WPA2-PSK (recommended).
4. Enter your password and save your settings.

4. Setting up a static IP address (if DHCP does not work)

If the TV gets an error 102 If your router is experiencing issues or intermittently loses connection, the router's DHCP server may be malfunctioning. In this case, assign a static IP manually.

Instructions:

1. Find out your network parameters:
   • The IP address of the router (usually 192.168.0.1 or 192.168.1.1).
   • Subnet mask (usually 255.255.255.0).
   • DNS address (can be used 8.8.8.8 from Google).

On your TV, go to Settings → Network → Wi-Fi connection → Advanced.

Select Configure IP manually and enter the parameters:

• IP address: For example, 192.168.0.100 (the last digit must be different from the router IP).
• Gateway: IP address of the router.
• DNS: 8.8.8.8 or 1.1.1.1.
• Save the settings and restart the TV.

Important: If the IP address you are trying to assign to your TV is already in use on your network, a conflict will occur. Check for occupied addresses through the router's web interface (section DHCP Clients List).

5. Solving Common Wi-Fi Problems on LG Smart TVs

Even after a successful connection, problems may arise: connection interruptions, low speed, or the inability to connect to certain services (for example, Netflix or YouTube). Let's look at typical scenarios.

The TV doesn't see the network.

Possible causes and solutions:

• 📡 The router operates in 802.11ac mode only. → Switch to mixed mode 802.11n/ac.
• 🔒 MAC address filtering is enabled → Add the TV's MAC address to the router's whitelist.
• 📶 The network broadcasts only in the 5 GHz range. → Enable 2.4 GHz broadcasting or update your TV firmware.
• 🔌 The router's power-saving mode turns off Wi-Fi. → Disable the option Wi-Fi Schedule or Power Saving in the router settings.

The network connects, but the internet doesn't work.

Check the following:

• 🌐 DNS servers: try changing to 8.8.8.8 or 1.1.1.1.
• 🔄 IP issues: Assign a static IP (see section 4).
• 🛡️ Router firewall: temporarily disable it in settings.
• 📦 Device restrictions: Some routers block new devices (check Access Control).

Low speed or constant interruptions

For diagnostics:

1. Run a speed test on your TV: Settings → Network → Network Test.
2. Compare with the speed on other devices (phone, laptop).
3. If the speed is low only on TV:
   • Switch from 2.4 GHz to 5 GHz (or vice versa).
   • Change the Wi-Fi channel in the router settings (optimal channels for 2.4 GHz: 1, 6, 11).
   • Reduce the channel width with 40 MHz to 20 MHz (helps with interference).

How to check Wi-Fi channel load?

Use network analysis applications such as:

- WiFi Analyzer (Android)

- NetSpot (Windows/macOS)

- AirPort Utility (iOS)

The optimal channel is the one with the least amount of intersections with neighboring networks.
