The most common reason your LG TV loses WiFi or won't connect is that your router and TV are too far apart or blocked by walls and metal objects

WiFi signals weaken with distance and physical barriers. If your TV is more than 30 feet from your router, or separated by multiple walls, concrete, or metal cabinets, the signal may be too weak to connect or stay connected. Move your router closer to the TV, or move the TV closer to the router. If that is not possible, a WiFi extender placed halfway between them can help.

The second most common cause is that your TV and router are not on the same WiFi network. Some routers broadcast two networks at once: one on the 2.4 GHz band (older, slower, longer range) and one on the 5 GHz band (newer, faster, shorter range). Your TV may have connected to one band weeks ago, but your router may have switched which band is the default. Check your router's settings to see which networks it is broadcasting, then manually select the correct one on your TV.

A third cause is that your router requires a password you have not entered correctly on the TV. LG TVs are sensitive to spaces, capital letters, and special characters. If you have not changed your WiFi password recently, try entering it again, character by character, on the TV itself rather than copying and pasting.

Key Takeaways

  • Distance and physical barriers between your TV and router are the most common cause of connection problems—test by moving them closer together.
  • Your router may be broadcasting two separate networks (2.4 GHz and 5 GHz), and your TV may be trying to connect to the wrong one.
  • WiFi passwords are case-sensitive on LG TVs, so re-enter yours manually if the connection fails.
  • Restarting both your TV and router in the correct order (router first, then TV) fixes most temporary connection drops.
  • If your TV connects but then drops the connection every few minutes, your router may need a firmware update or your TV may need a factory reset.

How to restart your TV and router the right way

A restart often fixes connection problems because it clears temporary errors in both devices' memory. The order matters: restart your router first, wait for it to fully boot up (usually two to three minutes, when all lights stop blinking), then restart your TV.

To restart your LG TV, go to Settings, then General, then Restart. Select Yes and wait for the TV to power off and back on. Do not unplug it during this process. Once the TV has fully restarted and shows the home screen, try connecting to WiFi again by going to Settings, then Network, then WiFi Connection.

If restarting does not work, try a factory reset on the TV. Go to Settings, then General, then Reset to Initial Settings. This will erase all your saved networks and passwords, so you will need to re-enter them. A factory reset is more disruptive than a restart, but it clears out corrupted settings that a straightforward restart cannot fix.

Check whether your router is the problem or your TV

If your LG TV will not connect but other devices in your home (phone, laptop, tablet) connect to the same WiFi without trouble, the problem is almost certainly with the TV, not the router. Move on to the TV-specific steps below.

If multiple devices are having trouble connecting or staying connected, the problem is your router. Restart it first. If that does not work, check whether your router's firmware is out of date. Log into your router's settings page (usually 192.168.1.1 or 192.168.0.1 in a web browser, or through the router manufacturer's app) and look for a firmware or software update option. read and install any available updates, then restart the router.

If your router is very old (more than five years), it may not support the WiFi standards that newer LG TVs expect. Older routers sometimes use outdated security protocols that newer devices refuse to connect to. In that case, you may need to replace the router, or contact your internet provider to see whether they offer a newer model.

Forget the network on your TV and reconnect from scratch

Sometimes the TV's memory of your WiFi network becomes corrupted, and the TV keeps trying to use old or incorrect settings. Forgetting the network and reconnecting forces the TV to start fresh.

On your LG TV, go to Settings, then Network, then WiFi Connection. Look for your network name in the list. Highlight it and select Delete or Forget (the exact wording varies by TV model). Once it is deleted, go back to WiFi Connection and select your network again. Enter your password carefully, paying attention to capital letters and special characters.

If your network does not appear in the list at all, your router may not be broadcasting its name (SSID). Go back to WiFi Connection and look for an option to add a network manually or enter a hidden network. You will need to type your network name and password by hand. Check your router's label or settings page to confirm the exact network name.

Update your LG TV's software

LG releases software updates that fix WiFi bugs and improve connection stability. If your TV has not been updated in several months, an update may solve your problem.

Go to Settings, then General, then About This TV. Look for a Software Update or System Update option. If an update is available, select read and Install. The TV will restart during the update, so make sure it is plugged in and do not turn it off. Updates usually take five to fifteen minutes.

If your TV is set to auto-update, it may have already downloaded an update but not installed it. Check the same Settings menu to see whether an update is waiting to be installed. Some LG TVs also allow you to check for updates manually even if auto-update is on.

Check your router's WiFi settings for compatibility issues

Some older LG TVs do not support newer WiFi security standards. If your router is set to WPA3 (the newest standard), your TV may not be able to connect. Check your router's settings and look for the security type or encryption method. If it says WPA3, try changing it to WPA2, which is older but more widely supported by older devices.

You should also check whether your router is set to use only the 5 GHz band. Some newer routers allow you to disable the 2.4 GHz band entirely. Older LG TVs often only support 2.4 GHz. If your router is broadcasting only 5 GHz, your TV will not see the network at all. Enable the 2.4 GHz band in your router's settings.

If your router broadcasts both bands, make sure they have the same network name (SSID). Some routers split them into separate names like "NetworkName-2.4" and "NetworkName-5". If they are split, your TV may connect to one band but then lose the connection when it tries to switch to the other. Combine them into a single network name in your router's settings, or manually select the 2.4 GHz band on your TV and stick with it.

When to contact LG support or your internet provider

If you have tried all the steps above and your TV still will not connect, contact LG support. Have your TV model number ready (it is on the back of the TV or in Settings, then General, then About This TV). LG support can walk you through TV-specific troubleshooting steps or determine whether your TV has a hardware problem.

If other devices in your home are also having WiFi trouble, contact your internet provider instead. They can check your router's connection to their network and run a speed test to see whether the problem is on their end. Some providers will replace your router for free if it is faulty.

Before you contact either one, write down what you have already tried: which devices can and cannot connect, whether the problem started after a power outage or router update, and whether the TV connects briefly and then drops, or never connects at all. This information helps support staff narrow down the cause.

Frequently Asked Questions

Why does my LG TV connect to WiFi but then disconnect after a few minutes?

This usually means your TV is losing signal because it is too far from the router, or your router is overheating. Move the router to a more central location, or move the TV closer. If that does not work, restart your router and let it cool for a few minutes before turning it back on. If the problem continues, your router may be failing and need replacement.

Can I use a WiFi extender to connect my LG TV?

Yes, but it is not ideal. Extenders reduce your WiFi speed by about half because they have to receive and transmit on the same channel. If your TV is far from your router, an extender will work, but moving the router closer or using a wired ethernet connection (if your TV has an ethernet port) will give you better performance.

My LG TV says it cannot find any WiFi networks. What does that mean?

Your router is either off, too far away, or broadcasting on a band your TV does not support. Check that your router is powered on and all lights are on. If it is on, restart it. If your TV still sees no networks, log into your router's settings and make sure the 2.4 GHz band is enabled. Some newer routers disable it by default.

Do I need to reset my router to fix my LG TV's WiFi?

Not usually. A restart (turning it off and back on) fixes most problems. A reset (holding the reset button for ten seconds) erases all your settings and returns the router to factory defaults, which means you will have to set up your WiFi password and network name again. Only reset your router if a restart does not work and you are comfortable reconfiguring it.

Will changing my WiFi password fix the connection problem?

Only if you suspect someone else has connected to your network and is using up your bandwidth. Changing the password will not fix a connection problem between your TV and router. If you do change it, you will need to re-enter the new password on your TV in Settings, then Network, then WiFi Connection.
