Or is the TV stubbornly unable to detect your network, even though your smartphone connects without a problem? Wi-Fi problems on TVs LG — is one of the most common user complaints, and the causes can lie in both the router settings and the TV firmware itself. In this article, we'll look into it. all possible scenarios, from banal password entry errors to hardware malfunctions of the Wi-Fi module.

It is important to understand that the troubleshooting algorithm depends on symptomThe TV can: not see the network at all (Wi-Fi list is empty), see but don't connect (hangs on "Getting IP"), or connect, but without internet access (The Wi-Fi icon is there, but YouTube won't load). Each case requires its own approach. We'll start with the simplest solutions and gradually move on to the more complex ones—this way, you'll save time and frustration.

If your TV LG released before 2017 (for example, series LH60xx or UH61xx), please note: many models from that period use outdated Wi-Fi standards (802.11n (2.4 GHz) and may not support modern router settings. These will require separate steps—we'll outline them in the relevant sections.

1. Checking basic parameters: router and TV

Let's start with the obvious: 90% of problems with Wi-Fi connection on TVs LG are resolved at this stage. Most often, the following are to blame:

• 🔌 Wi-Fi is turned off on the router (physical button or setting in the admin panel).
• 🔒 Incorrect password - especially if you have recently changed it.
• 📶 Weak signal — the TV can “see” the network, but not maintain a connection.
• 🔄 Hidden Network Mode (Hidden SSID) - many models LG do not know how to connect to such networks without manual input.

• 📡 Does Wi-Fi work on other devices (smartphone, laptop).
• 🔍 Do neighboring networks see it? If yes, the problem is with your router; if not, the problem is with the TV's Wi-Fi module.
• 🔄 Is the router in the offline mode? 802.11r (Fast Roaming) - many televisions LG he is not supported.

3. Set the parameters according to the table above.
4. Save the changes and reboot the router.

If your router supports guest network, try connecting your TV to it. Guest networks are often assigned more "friendly" default settings.

Make sure that Wi-Fi is physically turned on (button on the case)

Check that the network is visible on other devices

Disable MAC address filtering (if enabled)

Set the channel manually (e.g. 6 or 11 for 2.4 GHz)

Reboot your router after making changes-->

3. Firmware Update: Why It's Critical for Wi-Fi

LG TVs with webOS often lose Wi-Fi connectivity after updating their router or switching providers.
