Bear in mind, you will need to tinker with your TV’s hardware, which involves removing the back panel. If you’re not comfortable with that, I recommend contacting LG’s support for more assistance. They might be able to provide you with a new TV model if your TV is under warranty. Either way, the project is very straightforward, and even people with no tech experience can do it.

So if you head over to the settings menu on your LG TV and select network, a notice should appear saying Wifi is turned off. There will be no option to turn it on with the remote. If you see that warning message, there’s a good chance our solution will work for you.

How to Fix LG TV Wifi is Turned off and Won’t Turn On

Restart LG TV

Did you know when you press the power button on your remote the TV does not actually shut down? It goes into standby mode. The easiest way to restart an LG TV is to hold down the volume down button and the Power key for 12 seconds until the LG logo appears.

For other alternatives, read our article on how to restart or reboot an LG TV.

Restarting or rebooting the LG TV is a very easy step to try before we get into anything else. It will at least us check if the Wifi problem is due to a software or hardware issue. If it’s a software issue, restarting the LG TV should fix it.

Restart the LG TV and then open the network menu to see if the Wifi is still not on. If the Wifi is on and you can see nearby networks, congratulations. You fixed it and you don’t need to keep reading this article.

Factory Reset

Factory resetting a TV will restore the default settings which can sometimes fix software issues. It’s fairly easy to reset an LG TV to factory settings.

However if it still shows a warning message, here’s what you need to do:

  • Open Settings
  • Choose General
  • Select “Reset to Initial Settings”
  • Wait for the LG TV to reboot.

Bear in mind, resetting the TV will remove all settings and data, including saved passwords and settings.

Clean LG TV Wifi Adapter Module

This is where the fun starts. The idea is to access the LG TV’s Wifi card to clean and reseat the connections. If your LG TV is a bit old, chances are some dust got into the panel and is blocking the Wifi adapter connections. I’ll show you how to clean it. Just remember to be careful and patient.

Here’s what you need to do:

Before you start, make sure to unplug the power cable. It might help to press the power button a few times to make sure all the electricity is drained from the TV before you start working on it.

Next, remove the back panel of your LG TV. On the back of the TV, take a Philips screwdriver and unscrew all the screws. There are usually close to ten to remove. Make sure not to lose them! When all the screws are removed, remove the rear panel, and you’ll see the exposed electronics.

Most LG TVs have similar electronics, although the components might be in different locations. Look for white ribbon cables with a blue marker, there might be two. One of the white cables should lead to a small black plastic compartment that is attached to the TV with a couple of screws.

Locate Wifi Compartment:

The Wifi adapter is inside that little box. The location might be different depending on your LG TV model but it shouldn’t be difficult to spot. You could research teardowns on your specific model to get an idea of where the adapter is located.

Remove the two screws, and turn the case over to take a look at the module. There are two plastic tabs on the side of the case that keep the module in place. The adapter should pop out of the case when you pull on the tabs. Put the case aside for now (don’t lose it!).

Disconnect the ribbon cable from the network adapter. Once you removed the network adapter, use a small brush to clean the module. Dust off the pins that connect to the ribbon cable as well.

Once you’re confident the card is clean, reconnect the cable (make sure it’s fully connected), and place the adapter back in the case. Screw the case back to the metal panel.

Re-assemble the Panel

Before re-attaching the whole back panel, I recommend testing the LG TV to see if cleaning the Wifi adapter fixed the issue. Plug the TV into the wall and turn it on using the remote.

Once the TV boots, open settings and navigate to the Network menu. Do you still see the Wifi error? If you fixed the issue, it will automatically start searching for nearby Wifi networks and you’ll see a list on the screen.

For most people, removing and cleaning the Wifi adapter will fix LG TVs Wifi not turning on issue. Didn’t work for you? Chances are the Wifi card is broken and you’ll need a replacement. In that case, it’s best to call LG’s official support. There might be a chance you received a faulty unit and can get a free replacement.


I know how frustrating it is when the internet refuses to work on your LG TV. In most cases, cleaning the Wifi module and reseating the cables will fix the issue. It’s surprising how a simple DIY project can bring your network card back to life.
