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

Modern televisions LG Smart TV with the operating system WebOS provide access to streaming services, online cinemas, and even cloud gaming—but only with a stable internet connection. Most users choose the wireless method via Wi-Fi, and this is logical: there is no need to pull cables around the apartment, and the speed of modern routers (even in the budget segment) is enough to broadcast video in 4K HDR.

However, in practice, the connection doesn't always go smoothly. Sometimes the TV doesn't detect the network, sometimes it constantly drops the connection, or sometimes it requires you to enter the password 10 times. In this article, we'll look into it. All current ways to connect LG TV to Wi-Fi in 2026, including hidden settings for improving the signal and resolving common issues. This manual is suitable for models with WebOS 4.0 and newer (including LG OLED C3, QNED 90, NanoCell 86 and budget series).

If your TV was released before 2018 (for example, LG UK6300 or LJ550V), some menu items may differ, but the general setup logic remains the same. For older models, NetCast (before 2014) it is better to use a wired connection via LAN port, since their Wi-Fi modules often do not support modern standards 802.11ac/ax.

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

Before you mess around with your TV settings, make sure the problem isn't with your home network. Here's 4 key points, which are often missed:

• 📶 Router signal at the TV installation locationUse an app like Wi-Fi Analyzer (Android) or NetSpot (iOS/macOS) to measure the signal strength near the TV. The optimal value is: -60 dBm and higher. If the value is worse -70 dBm, you will have to move the router or use repeater.
• 🔒 Network encryption typeLG TVs do not support outdated standards such as WEP or TKIP. It should be selected in the router settings. WPA2-PSK (AES) or WPA3-Personal. If used WPA/WPA2 Mixed, try switching to clean WPA2.
• 📡 Wi-Fi operating modeIn the router settings, check that the mode is enabled. 802.11n/ac/ax (and not only 802.11b/g). For maximum compatibility, please select 20/40 MHz in the channel settings (auto mode may not work stably).
• 🔄 DHCP serverMake sure automatic IP address assignment is enabled on your router. If static addresses are assigned manually, the TV may not have enough available bandwidth.

Please pay special attention to Wi-Fi channelMany routers by default select busy channels (for example, 6th or 11th in the range 2.4 GHz), which leads to interference. Manually set the channel with the minimum load - this can be done through the router's web interface (usually at 192.168.0.1 or 192.168.1.1).

⚠️ Attention: If your router is in the mode 802.11r (Fast Roaming), disable this feature - it may conflict with the connection algorithms of LG TVs.

4. Connection Optimization: How to Speed ​​Up Wi-Fi on LG TV

Even if the TV is connected to the network, this does not guarantee stable operation. When watching 4K-content or online games through GeForce NOW You may experience some slowdowns. Here's how to improve the situation:

• 📶 Range selection. If your router supports 5 GHz, connect your TV to this network—it's less crowded and provides higher speeds. Cons: Range 5 GHz less, so check your signal level.
• 🔄 Changing DNS. By default, providers use their own DNS servers, which can slow down your connection. Go to Settings → Network → Wi-Fi → Advanced and manually enter:

  Primary DNS: 8.8.8.8
  Secondary DNS: 1.1.1.1

• 🛡️ Disabling energy saving. In some models (LG B2, A2) there is a function Saving Wi-Fi energy, which reduces speed when idle. Disable it in Settings → All settings → General → Eco mode.
