Let's start with the obvious: most connection problems can be solved in 5 minutes if you know where to look. Here five most common reasons, why TV LG Doesn't catch Wi-Fi or doesn't connect to the network:

• 🔒 Incorrect password - especially if you have changed it recently.
• 📡 Weak signal or interference from other networks (channels 1, 6, 11 are usually the busiest).
• 🔄 Outdated TV firmware — valid for 2018–2019 models.
• 🚫 MAC address blocking TV in the router settings.

If your case doesn't fall on this list, don't worry. We'll cover it below. all possible scenarios, including rare ones (such as an IPv6 conflict or an authentication error due to special characters in the password). In the meantime, please answer one question so we can more accurately identify your issue:

Before proceeding to complex settings, please do the following: basic diagnostics:

Router settings that prevent LG TV connection

In 60% of cases, the problem lies not with the TV, but with the router. Modern routers (especially from ASUS, TP-Link Archer or Keenetic) have many functions that may conflict with older firmware LG Smart TVLet's look at the key parameters worth checking.

The first thing to do is log into the router's web interfaceThis is usually done through a browser at the address 192.168.0.1 or 192.168.1.1 (The exact address is indicated on the sticker on the back of the device.) The default login and password are also there - most often it is admin/admin.

1. Wi-Fi operating mode (802.11 b/g/n/ac/ax)

Televisions LG Different years support different Wi-Fi standards:

🔹 Solution: In the router settings (Wireless → Wi-Fi Settings) install:

• 📶 Standard: 802.11n/ac (for TV 2019+)
• 📊 Channel width: 20/40 MHz (not 80 or 160!)
• 🔒 Security type: WPA2-PSK (not WPA3 and not mixed mode)

2. MAC address filtering

Some routers block new devices from connecting unless their MAC address is whitelisted. To check this:

1. Find your TV's MAC address in Settings → General → About TV → Network Information.
2. In the router's web interface, go to Wireless Mode → MAC Filter.
3. Make sure your TV's MAC address is on the allowed list (or disable filtering altogether).

How can I find out the MAC address if my TV is not connected to the network?

Press on the remote control Settings → All Settings → General → About TV → NetworkThe MAC address will be displayed even without a connection.

3. IP address conflict (DHCP)

If your TV doesn't receive an IP address automatically, it won't be able to connect to the network. Check:

• 🔄 Is it enabled? DHCP server on the router (Local Area Network → DHCP).
• 📱 Are there any other devices on the network with static IP, which conflicts with TV.
• 🔧 Try manually assigning an IP address to the TV in the router settings (by linking it to the MAC address).

⚠️ Attention: If you have dual-band router (2.4 + 5 GHz), make sure the TV is connected to the correct frequency. Many models LG 2018-2020 do not support 5 GHz!

LG TV settings to check
