Setting up Wi-Fi on an LG TV: From Basic Connection to Troubleshooting Speed ​​Issues

Modern televisions LG with the operating system webOS offer a wide range of options for viewing online content - from YouTube And Netflix to gaming services like GeForce NOWHowever, without a stable Wi-Fi connection, all this functionality remains unavailable. Many users encounter difficulties even when entering a password or selecting a network, not to mention more complex issues such as constant connection breaks or low speed when watching 4K video.

In this article we will look at all Wi-Fi connection methods on TVs LG — from 2016 models (webOS 3.0) to the latest OLED Evo And QNED 2026–2026. We will pay special attention choosing the optimal frequency (2.4 or 5 GHz), setting up the router for maximum stability and solving typical errors like IP conflict or DNS errorsIf your TV stubbornly "doesn't see" the network or connects but doesn't open apps, you'll find help here. concrete steps for diagnostics.

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

Before you go into your TV settings, make sure the problem isn't in router or environmentAbout 40% of support requests LG are not related to a TV malfunction, but to external factors:

✅ Distance to the routerThe optimal location is no further than 10 meters in direct line of sight. Concrete or brick walls can weaken the signal. 50–70%, especially at 5 GHz. If the TV is in another room, consider the option with Mesh system or repeater.

✅ Network congestionIf more than 10 devices (smartphones, laptops, smart speakers) are connected to the router simultaneously, the TV may not have enough bandwidth. Check the list of connected devices in the router's admin panel (usually at 192.168.0.1 or 192.168.1.1).

✅ Router operating modeSome models (for example, TP-Link Archer C6 or ASUS RT-AX88U) are included by default automatic channel selectionThis can lead to frequent reconnections. We recommend manually setting a fixed channel—for example, 6th or 11th for 2.4 GHz and 36–48th for 5 GHz.

⚠️ Attention: If your router supports the standard Wi-Fi 6 (802.11ax), but the TV was released before 2020, turn on compatibility mode with Wi-Fi 5 (802.11ac) in your router settings. Otherwise, connection issues may occur.

• 🔌 Check the router power: Reboot it (turn it off for 30 seconds). This solves up to 30% of connection problems.
• 📶 Disable VPN on your router: some firmware (for example, DD-WRT) block traffic from TVs.
• 🔒 Make sure MAC filtering is disabled: Otherwise, you will have to manually add the TV's MAC address to the whitelist.
