LG TV Can't Detect Wi-Fi: What to Do and How to Fix It

The situation when smart Smart TV The problem of losing wireless network detection is familiar to many owners of modern technology. You've turned on your favorite TV show, but the screen says there's no connection, even though the router is working properly. This could be a temporary software glitch or a more serious hardware problem with the module.

Before panicking or taking your device to a service center, it's worth running a basic diagnostic. Often, the problem lies in something as simple as router overheating or a misconfigured IP address. In this article, we'll walk you through a step-by-step procedure that will help you get your router back up and running. LG TV online.

Start with the simplest thing—restarting the entire system. Unplug the TV, wait a minute, and then plug it back in. This will clear the RAM and clear any temporary errors in the Wi-Fi module drivers.

Basic reboot and router check

The first step is to rule out problems at the signal source. If the router is overloaded, it may stop assigning IP addresses to new devices. Check whether other devices, such as smartphones, tablets, or laptops, are connected to the Wi-Fi network.

If other devices also can't see the network or don't have internet access, the problem is definitely not with the TV. In this case, you need to reboot the router. Unplug it for 15-20 seconds, then plug it back in and wait for the indicators to fully load.

Sometimes an LG TV can't detect Wi-Fi because the router's list of connected devices is full. Try temporarily disabling other devices and leaving only the TV connected. It's also worth checking if your router is set to "Guest Network" mode, which often hides the SSID or restricts access.

⚠️ Note: If your router is very old and only supports the 802.11b/g standard, and your newer LG TV is configured for 5 GHz or requires WPA3, compatibility may not be possible. Check your router's specifications.

Make sure the date and time on your router are set correctly. An incorrect system time can block a secure connection due to security certificates becoming out of sync.

Setting the date and time in webOS

One of the most common and subtle reasons for Wi-Fi module failure is a faulty date. Encryption protocols WPA2 And WPA3 Require a current system time to verify security certificates. If the TV is set to 2010, but the certificate was issued in 2026, the connection will fail.

To fix this, go to the settings menu. Press the gear button on the remote and go to "General." Find "Date & Time." Make sure automatic syncing via network is selected, but if the network isn't working, you'll have to set the time manually.

Use the navigation buttons to accurately set the current time. Once set correctly, try scanning for wireless networks again. Often, the TV will immediately find your router and connect successfully.

Some users note that changing the time zone to a neighboring region and back also helps clear network errors. This forces the operating system WebOS Re-initiate network services.

Changing DNS and network settings

If your TV detects the network but doesn't connect, or displays "No internet connection," the issue may be with your provider's DNS servers. Default settings are often unstable. Manually registering reliable addresses from Google or Cloudflare resolves the issue in most cases.

To do this, go to Settings → Network → Wi-Fi connectionSelect your network and click "Additional settings" or "Advanced settings." Find the DNS field and uncheck "Automatic."

Enter the following values ​​in the DNS server fields:

• 🌐 Primary DNS: 8.8.8.8
• 🌐 Alternative DNS: 1.1.1.1
• 🌐 Backup: 8.8.4.4

After entering the data, save the settings and reboot the TV. This method is especially effective if your ISP blocks some requests or uses its own, slow name servers.

Parameter	Default value	Recommended value	Effect
DNS Server 1	Auto (from provider)	8.8.8.8	Search stability
DNS Server 2	Auto (from provider)	1.1.1.1	Response speed
IPv6	Included	Off	Conflict resolution
QuickStart+	Included	Off	Resetting the Wi-Fi module

⚠️ Note: Disabling QuickStart+ will make the TV take longer to turn on, but will force the Wi-Fi module to completely reboot each time it starts, eliminating driver freezes.

Reset network and system settings

When software glitches accumulate, a simple reboot may not help. In the operating system WebOS There's a full network settings reset function. This will return your connection settings to factory defaults.

Find the "Network" section in the menu and select "Wi-Fi Settings" or "Advanced Settings." At the bottom of the list, you should see an option to "Clear connection settings" or "Reset network." Confirm the action.

After this, the TV will lose all saved passwords. You will need to re-find your network and enter the password. Make sure you enter the password correctly, taking into account the case of the letters.

If resetting the network doesn't help, you can try a more radical method - a factory reset. This will remove all installed apps and accounts. Go to Settings → General → Factory Reset.

Use this method only if other methods have failed. Before resetting, make sure you remember your LG account and app login information, as you'll need to re-enter them.

Updating TV firmware

Outdated software is a common cause of conflicts with new router encryption standards. LG regularly releases updates that fix Wi-Fi module bugs. If your TV connects to the internet via a cable or mobile hotspot (sharing from your phone), update the software using the menu.

Path to update: Settings → All settings → Support → TV software update → Check for updatesIf the system finds a new version, agree to install it.

If Wi-Fi isn't working at all and you don't have a LAN cable handy, you can update via USB. You'll need a computer and a USB flash drive with a capacity of up to 8 GB, formatted in FAT32.

Where can I find the firmware?

Go to the official LG website, go to the support section. Enter your TV model (found on the sticker on the back). Download the firmware file for your model and region. Unzip the archive and place the .epk file on the root of a flash drive. Insert the flash drive into the TV's USB port and follow the on-screen instructions.

The update process may take 10-15 minutes. Important: Do not turn off your TV during the update, even if the screen is blank. Interrupting the process may damage the motherboard.

Hardware problems and the Wi-Fi module

If software methods have been exhausted and the TV still doesn't detect any networks (or the list is empty), there's likely a hardware problem. LG TVs have a separate Wi-Fi module responsible for wireless communication, which can fail over time.

Common symptoms of failure:

• 🔌 Gray Wi-Fi icon in the menu that does not activate.
• 🔌 The TV only sees 2.4 GHz networks, but ignores 5 GHz (or vice versa).
• 🔌 Constant connection drops despite a normal router signal.

In some models, the Wi-Fi module is integrated into the main board, while in others, it's a separate, removable board connected via USB inside the case or a dedicated port. Diagnostics will require disassembling the TV and using a multimeter.

⚠️ Caution: Disassembling the TV yourself will void the warranty. If the device is under warranty, contact an authorized service center immediately. Do not open the back cover!

As a temporary solution, you can use an external USB Wi-Fi antenna if your TV model supports external adapters (a list of compatible models is available on the LG website). However, a simpler and more reliable solution is to use a wired LAN connection or set up Miracast/AirPlay streaming from your smartphone, using the phone as a bridge.

Why does the TV see the 5 GHz network but not connect?

The problem is most likely with your router's broadcast channel. LG TVs may not see channels above 11 in the 2.4 GHz band or specific channels in the 5 GHz band. Try setting a static channel (e.g., 1, 6, or 11 for 2.4 GHz) in your router settings instead of "Auto."

Is it possible to connect a TV to Wi-Fi without a remote control?

Yes, if you have a smartphone with an IR port or the LG ThinQ app installed previously. You can also connect a USB keyboard and mouse if your TV supports HID devices and configure the settings using them.

Does antivirus software on a router affect TV connection?

Yes, some router security features (such as ad blocking or parental controls) may interfere with Smart TV connection. Try temporarily disabling your router's security filters to test.
