LG TV Not Connecting to WiFi

To fix an LG TV not connecting to WiFi you need to reset your TV by power cycling it. Unplug it, hold the power button down for 15 seconds, then plug your TV back in after waiting a further 30 minutes. You can also try updating your TV’s IP and DNS, and resetting your WiFi network.


If your LG TV won’t connect to WiFi after trying the above, then you should go through every step below in order, and I’m confident we will get it working again for you.


1. Reset Your LG TV’s WiFi

Although this might seem a basic step, power cycling your TV is often the best way to fix your LG TV not connecting to Internet.

With modern electronics, it’s possible that the problem is caused by something stuck in your TV’s flash memory.

Power cycling your TV will clear out any issues with non-permanent memory and reset your main board without losing your personal settings.

This is quick and painless and won’t cause you to lose any of your saved settings.

  1. Switch off and unplug your TV.
  2. Hold down the physical power button on the TV for at least 15 seconds.
  3. Wait for at least 30 minutes for any residual power to drain from the TV’s capacitors (which are capable of storing charge for several minutes).
  4. Plug your TV back in and try switching it on. You should see a red light if you have been successful.

Make sure you do wait for the full 30 minutes before plugging your TV back in – you would be surpised how long the components within your TV can hold charge, and you want to make sure it has fully reset.

Although this seems a very basic step, don’t overlook it because in the vast majority of cases a simple soft reset fixes most issues.

Most people will now have their TV fixed and back up and running, but if your LG TV is not connecting to WiFi after resetting, then we’ve got a few more basic fixes to try before getting into the hardware fixes.


2. LG TV Not Connecting to WiFi Automatically

If your TV WiFi is not connecting automatically, and it is working on other devices, then check for an issue with your TV’s IP and DNS addresses.

In most cases, your TV should be setup to automatically select an IP address from your router, and usually also automatically pulls a DNS address, which is used to resolve IP addresses that your TV connects to, creating the URL that you see in the address bar of your browser.

But it’s possible that IP address lookup might have been set to Manual, and your DNS settings might be conflicting between your TV and WiFi router.

To fix this, press Settings on your remote, then go to Network -> WiFi Connection -> Advanced Settings -> Edit.

If Set Automatically is set to Off, then change it to On and restart your TV. This will make your TV select an IP address automatically from your router.

If Set Automatically is On, then try switching it Off, and change the DNS Server to 8.8.8.8, which is one of Google’s DNS servers that we know definitely works.

Restart your TV and try your apps again.


3. Make Sure Your WiFi Password is Correct

If your LG Smart TV is not connecting to WiFi at all, this could be a sign that the password you are entering is incorrect, or the WPS setup failed.

If you used WPS, where you press a WPS button on your router and your TV automatically discovers the network and login details without any further input than you, then try entering your password manually.

If you entered it manually before, try re-entering your password, but this time make sure the Show password option is selected so that you can confirm this is correct.


4. Check Your Router is Not Set for MAC Address Filtering

MAC address filtering allows you to specify which devices are allowed to connect to the Internet using their unique MAC addresses, which every Internet capable device has.

If you, or someone in your family, has switched this on at the router level, your LG TV won’t connect to the Internet even if it can connect to your WiFi.

Login to your router by typing the Admin IP address into your phone’s or computer’s browser. This is listed on a label on your router (usually 192.1.1.1 or similar), along with the admin login info.

Go to Advanced or Expert Settings and find MAC Filtering. Make sure this is turned off.

5. LG TV Keeps Disconnecting from WiFi

If your LG TV keeps disconnecting from WiFi, then you need to make sure that your router is switched on and working properly, and that there is no interference or blocking of the WiFi signal between your router and TV.

The easiest way to check that your router is working is to use another device, like a phone or iPad. Make sure this is using the same WiFi network as your TV, and check you are fully able to access the Internet.

WiFi interference can be a bit harder to discover, but if you can, try moving your TV as close to your router as possible, ideally within the same room.

If your TV and router are in separate rooms, then try taking another device with WiFi capabilties like your phone up to your TV, and see if you are able to successfully browse the Internet from the same location as your TV, on the same home network.

If your TV won’t connect to the Internet but other devices will from the same location, then you can assume your router’s WiFi signal is good, and the problem most likely lies within your TV.


6. Update Your LG TV’s Firmware

If your LG TV WiFi is not turning on, then updating your firmware is the best option.

Software and firmware issues have been known to cause problems with the WiFi on LG TVs.

As with any product, you should ensure that you have updated your TV’s firmware to the latest version, even if it is new.

Smart LG TVs support auto-updating of firmware, but you can’t assume that this is turned on for you.

To check that auto-updating is on for firmware / software on your smart LG TV:

lg tv remote settings button
  1. Press the Settings button on your remote and go to All Settings.
  2. Click Support.
  3. Then Software Update.
  4. Agree to any terms and conditions that may popup, then switch on Auto Update if off.
  5. You can also manually check for updates here.

For older LG TVs:

  1. Press the Settings button on your remote and go to All Settings.
  2. Go to General.
  3. Then About This TV.
  4. Check Auto Updates are on, and use the Check for Updates button to manually see if you are running the most recent firmware version.

For some LG TVs, you’ll need to update the firmware by USB. To do this:

  1. Go to the LG Software Drivers site.
  2. Enter your TV’s model number and find it on the site.
  3. Put a USB stick into your computer and create a folder on it called LG_DTV.
  4. Right-click the firmware ZIP file on LG’s site and Extract All to the folder on your USB stick.
  5. Once complete, eject your USB stick.
  6. Insert the USB stick into your TV’s USB port and switch it on.
  7. The TV will automatically search for the folder you created and should display USB UPDATE READY.
  8. Select Install.
  9. Follow the on-screen instructions, then switch off your TV for 10 seconds and power back on to complete the update.

7. Switch Your TV / Router to 2.4GHz

It’s possible that your LG Smart TV won’t connect to WiFi because of an issue with your 2.4GHz WiFi channel.

Login to your routers landing page, usually found by typing 192.1.1.1 or 192.1.1.0 into a browser on your phone or computer (the exact IP will be on a label on your router).

Find the login info on your router’s label, and take a look at the overview page to see whether your TV is connecting on 2.4GHz or 5GHz.

If it is connecting on the 5GHz channel, try changing the settings in your TV’s Network page to connect only on 2.4GHz.

You can also update the channel frequencies in the router itself, usually found under Expert Settings or Advanced Settings, changing these values and retesting your TV’s Wifi connection to see if they make any difference.

8. Check Your TV’s Time and Date

Because your router will automatically assign an IP address for a fixed period of time, if your TV’s time and date is wrong, it can cause the IP address to “expire” and prevent connection to the router.

IP addresses set by your router will have a Lease Expiration of several years (and this can be checked within the settings page for your router), so if your TV has a time and date several years away from the current date/time, this can cause the IP lease to expire.

Go into the Settings for your TV and manually update the date and time to today if it is not already showing this.


9. Turn Off Quickstart

Some LG TVs have a Quickstart feature which can interfere with establishing a WiFi connection.

If your LG TV WiFi is not working at all, then press Settings on your remote and go to All Settings -> General -> Quickstart -> Off and restart your TV to see if that has fixed the problem.


10. LG TV Factory Reset

Returning your TV back to its factory settings is a more extreme step, as it will delete any personalization features, downloaded apps or connected devices, but it’s always worth a shot when other methods haven’t worked.

To factory reset an LG Smart TV:

  1. Press the Home button on your remote and go to All Settings.
  2. Then General.
  3. And System (or skip to the next step on older models).
  4. Choose Reset to inital settings.
  5. Follow the on-screen instructions and hit Confirm.
  6. Enter your PIN, which by default is 0000 (four zeroes) or 1234 for LG.
  7. Then select Restart in the popup.

If you don’t have your remote, then to reset an LG TV:

  1. Hold down the TV’s Power Button for 10 seconds, which will be underneath the screen on on the side.
  2. Use the Vol + or – or Channel + or – to scroll to Menu.
  3. Go to All Settings.
  4. Then General.
  5. And Reset.
  6. Follow the on-screen instructions and hit Confirm.
  7. Enter your PIN, which by default is 0000 (four zeroes) or 1234 for LG.
  8. Then select Restart in the popup.

If you have changed your LG TV’s PIN and can’t remember what it is:

  1. Press the Home button on your remote and go to All Settings.
  2. Then Support.
  3. Go to Advanced Settings.
  4. Then Safety.
  5. And Reset Password.
  6. On your remote, press Channel Up twice, then Channel Down once, followed by Channel Up once.
  7. Put 0313 in the box.
  8. Then 0000.
  9. Then choose a new PIN that you can remember.

11. Reset Your Router

If you’re still seeing LG TV network connection problems, then you can first try a soft reset of your router – unplugging it for 30 seconds – to see if that fixes your issue.

If not, try a hard reset of your router, pressing a paperclip or similar into the small reset hole usually found on the back of your router.

You will need to hold the paperclip on the reset button for at least ten seconds to be sure your router is fully reset.

This will remove any personalisation settings you have made on your router, such as a changed WiFi password or network name, so be sure you still have the default WiFi logins for the router. These are usually on a sticker on the router body.


12. Use an Ethernet Cable

Finally, if you are still unable to get the WiFi working on your TV, you might have to resort to using an Ethernet cable.

Either your TV or router should have come with one, and this will give you a wired Internet connection which will bypass your WiFi.

If your TV is in a different room from your router and it isn’t practical to use an Ethernet cable, or if your LG TV keeps dropping the wired Internet connection, then there is still one final hardware fix that will get your WiFi working again.


13. Replace the WiFi Module

If none of the previous steps have worked, then you are most likely suffering from a failed WiFi module which is pretty easy to replace yourself.

Take a look at the video below for a step-by-step guide to do this. You will need to open up your TV which will invalidate it’s warranty, so this is really only a solution for TVs that are over one year old.


LG TV WiFi Issues Troubleshooting

For more specific LG TV Internet issues, take a look at the troubleshooting steps below.


How to Connect Old LG TV to WiFi

Old LG TVs that do not have native WiFi capabilities cannot be directly connected to WiFi without an adapter. The most common adapters to use are Firesticks, Chromecast or Roku streaming sticks.

Plug one of these into your TV’s HDMI port, with the power cable plugged into the TV’s USB port, then follow the on-screen instructions for your streaming stick to connect to WiFi.


How to Connect LG TV to WiFi Without Remote

If you’ve lost your remote or it doesn’t work, then you can connect to LG Smart TVs without a remote by the LG TV Plus app.

As long as you are using a relatively modern Smart TV, and your TV can connect to your home WiFi network, then you can use the apps like the one above on your phone even if your TV can’t connect to the Internet.

If your TV can’t connect to WiFi at all, then apps which use the infrared capabilities of your phone can work, like the Remote for LG TV.

Alternatively, try plugging a USB keyboard into your TV’s USB port and use the direction keys in combination with any Menu buttons or similar on the TV case to navigate the internal menus and connect to your home network.


LG TV Support and Warranty

You can check your warranty information direct with LG.

Unfortunately, warranties typically only last a year unless you have already paid to extend it.

Because WiFi issues can occur at any time, if your TV is under one year old, return your TV under warranty and get it fixed.

You can use the LG support site to help diagnose your problem, but if you are at this stage, then you are better off calling them direct on:

  • 850-999-4934 or 843-243-0000 (Mon. – Sun., 8am – 9pm EST)

You can also email them directly, or even email the president of LG customer care!

Even if LG won’t fix your TV, they might still offer you a discount off a future model if you pester them hard enough! This is always worth a try in my experience.


So, How Do You Fix an LG TV Not Connecting to WiFi?

To fix an LG TV not connecting to WiFi:

  1. Power cycle your TV to reset it.
  2. Update your IP to obtain automatically and your DNS to 8.8.8.8.
  3. Make sure your WiFi password is correct.
  4. Confirm your router isn’t MAC address filtering.
  5. Check for signal interference.
  6. Update your TV’s firmware.
  7. Switch your TV to the 2.4GHz WiFi channel.
  8. Check your TV’s time and date.
  9. Turn off Quickstart.
  10. Factory reset your TV.
  11. Reset your router.
  12. Use an Ethernet cable.
  13. Replace the WiFi module.

Hopefully you’ve now got your TV’s WiFi back up and running. If not, leave me a comment and I’ll see what more I can do to help.
