Your LG TV loses the WiFi signal for one of five reasons: the router is too far away, the password is wrong, the TV's WiFi chip needs a restart, the router itself is having trouble, or the TV's software is out of date

Most connection problems fall into the first three categories and take less than ten minutes to fix. The TV sits in one room, the router in another, and the distance or walls between them block the signal. Or you typed the password wrong — LG TVs are case-sensitive, so "MyPassword" is not the same as "mypassword". Or the TV's WiFi radio got stuck and needs a power cycle to recover.

Before you do anything else, restart your TV the way it matters: unplug it from the wall outlet, wait 30 seconds, and plug it back in. This clears the TV's memory and resets the WiFi chip. Then try to connect again. If that works, you are done. If not, move to the steps below in order.

Key Takeaways

  • Restart your TV by unplugging it from the wall for 30 seconds, which fixes most connection problems without any other steps.
  • Check that you are typing the WiFi password exactly as it appears on your router or in your router's settings — LG TVs treat uppercase and lowercase as different.
  • Move your router closer to the TV or remove obstacles like metal filing cabinets and microwaves that block WiFi signals.
  • If the TV connects but drops the signal often, restart your router by unplugging it for 30 seconds as well.
  • Check for a software update on the TV itself by going to Settings, then Support, then Software Update.

Check your WiFi password character by character

Open your router's settings page or look at the sticker on the back of the router itself. Write down the WiFi password exactly as it appears — including capital letters, numbers, and symbols in the right order. LG TVs do not forgive typos or case mistakes.

On your TV, go to Settings, then Network, then WiFi. Select your network name from the list. When the TV asks for the password, type it slowly and check each character before you press Enter. If you are not sure whether a letter is uppercase or lowercase, check your router again.

If you have changed your WiFi password recently and do not remember the new one, you can reset it through your router's settings page. Go to your router's IP address (usually printed on the router itself or in your router's manual) in a web browser on your computer, log in, and look for WiFi settings or Security settings. Change the password to something you will remember, then try the TV again with the new password.

Move the router closer to the TV or remove obstacles

WiFi signals weaken over distance and cannot pass through certain materials. If your router is in a bedroom closet and your TV is in the living room on the other side of the house, the signal may not reach it reliably. Move the router to a more central location, or move it to the same room as the TV temporarily to test whether distance is the problem.

Metal objects block WiFi signals more than anything else. Microwave ovens, metal file cabinets, and metal shelving can all interfere. If your router sits next to a microwave or behind a metal bookcase, move it away. Concrete walls and water (like a fish tank or water heater) also weaken the signal, though not as much as metal.

If moving the router is not practical, consider a WiFi extender or mesh router system. These devices repeat the signal or create multiple access points so the TV can connect from farther away. Budget models start around $30 to $50, and mid-range mesh systems cost $100 to $200 for a two-unit setup.

Restart your router and check for outages

Your router itself may have stopped working properly. Unplug it from the power outlet, wait 30 seconds, and plug it back in. Wait two to three minutes for it to fully restart — you will see lights on the front stop blinking and settle into a steady pattern. Then try the TV again.

While the router restarts, check whether your internet is actually working. On a phone or computer connected to the same WiFi, try to load a website or stream a video. If nothing loads, your internet service is down. Call your internet provider or check their website to see if there is an outage in your area. If there is, you will have to wait for them to fix it — there is nothing you can do on your end.

If your internet works on other devices but the TV still will not connect, the problem is the TV itself, not the router. Move to the next section.

Update the TV's software

LG releases software updates that fix WiFi bugs and improve connection stability. Check whether your TV has a pending update. Go to Settings on the TV, then Support, then Software Update. If an update is available, the TV will tell you. Select read and Install, and let it run — this usually takes five to ten minutes.

The TV needs to be plugged in and connected to power for the entire update. Do not unplug it or turn it off while the update is running. If the update fails, the TV will usually try again the next time you turn it on.

After the update finishes, restart the TV by unplugging it for 30 seconds, then try to connect to WiFi again.

Forget the network and reconnect from scratch

Sometimes the TV's memory of your WiFi network gets corrupted, and the TV tries to use old or wrong settings. Clear that memory and start over. Go to Settings, then Network, then WiFi. Find your network name in the list, select it, and look for a "Forget" or "Remove" option. Select it.

Now go back to the WiFi list and select your network name again. The TV will ask for the password as if it is the first time. Type it carefully and slowly. This forces the TV to store fresh settings instead of using the corrupted ones.

Check whether your router uses WiFi 6 or a frequency the TV does not support

Older LG TVs do not support the newest WiFi standards. If you recently bought a new router with WiFi 6 (also called 802.11ax), your older TV may not be able to connect to it at all. Check your TV's manual or LG's website to see which WiFi standards it supports — usually listed as 802.11a, 802.11b, 802.11g, 802.11n, or 802.11ac.

If your router is newer than your TV, you may be able to turn off WiFi 6 in the router's settings and use WiFi 5 (802.11ac) instead. Log into your router's settings page, find the WiFi settings, and look for an option to disable WiFi 6 or select a different standard. Your other devices will still work, and your TV should connect.

If your router does not have that option, or if your TV is very old and does not support even WiFi 5, you may need a different router or a WiFi extender that supports older standards.

Frequently Asked Questions

My TV connects to WiFi but keeps dropping the signal. What do I do?

Restart your router by unplugging it for 30 seconds. If the TV still drops the signal, move the router closer or remove obstacles between the router and TV. If the problem continues, the TV's WiFi chip may be failing — contact LG support or consider a replacement.

Can I connect the TV to WiFi using a hotspot from my phone instead of my home router?

Yes, most LG TVs can connect to a phone hotspot the same way they connect to a home WiFi network. Go to Settings, Network, WiFi, and select your phone's hotspot name from the list. Type the hotspot password. Be aware that streaming video over a phone hotspot uses a lot of data and may count against your phone plan.

What if I forgot my WiFi password and cannot find it anywhere?

Log into your router's settings page on a computer or phone. The router's IP address is usually printed on the back of the router (often 192.168.1.1 or 192.168.0.1). Log in with the router's admin username and password (also usually on the back), then look for WiFi settings or Security settings. You can see or change your WiFi password there.

Does the TV need to be connected to WiFi to watch cable or satellite TV?

No. If your TV has a cable or satellite box connected to it, you can watch those channels without any internet connection. WiFi is only needed for streaming apps like Netflix, YouTube, or your TV's smart features. Cable and satellite work through the box, not through the internet.

My TV is very old and will not connect to any modern router. What are my options?

You can use a WiFi extender that supports older WiFi standards, or you can connect the TV to the internet using an ethernet cable if your router has an ethernet port and is close enough to the TV. Some people also use a separate streaming device (like a Roku or Apple TV) connected to the TV's HDMI port instead of relying on the TV's built-in WiFi.
