It’s important to provide background information on a DNS before following this troubleshooting route. A Domain Name Service (DNS) is an extensive database containing every existing website’s name and aligned IP address.

Your home router, therefore, has a DNS database in it. However, the database on your router is severely limited by memory space, meaning it can only store some known IP addresses. As a result, your router will keep only the website addresses you use most often.

The best publicly available DNS configuration to switch to is Google’s DNS This opinion is primarily based on performance levels and often having a faster loading time due to the many queries and subsequent answers already held by the global system.

To change the DNS configuration of your LG TV, perform the following steps:

  • Open the ‘Quick Setting’ menu
  • Click ‘Network – Connected to Wireless’
  • Navigate to ‘WIFI connection’, ensuring you are currently connected to your WIFI
  • Click on ‘Advanced WI-FI Settings’
  • Click ‘Edit’
  • Turn off ‘Set Automatically’

3) Turn Off Dual Band Setting

LG TVs can most commonly connect to a 2.4 GHz or 5 GHz WiFi. However, many users’ reports state that a better connection experience was had when using the 2.4 GHz connection option.

To ensure that your TV uses only the single band option, you will need to disable the 5 GHz band via your WiFi router. Follow these points to disable the 5 GHz band:

  • Open your router’s administrative settings page. This process may vary slightly, depending on the router in place:
    • Access the admin panel by entering your router’s public IP address into the address bar of a web browser
    • Open the dedicated firmware software or use a mobile app provided by the router manufacturer
  • Select ‘Wireless Setting’ or ‘Dual-Band Setting’
  • Disable the ‘5 GHz’ band option
  • Save the change before exiting the admin panel
  • Restart the router to complete the process

The incorrect time zone on your LG TV has been reported as a potential cause for WiFi connectivity issues. Setting the time and date to the correct descriptions is a straightforward process. Here’s what you need to do:

  • Turn on your LG TV
  • Open the ‘Quick Setting’ menu

If you are still having difficulties connecting your LG TV to your desired WiFi network, then another possible solution is to straighten the WiFi module cables of your TV. While this might sound very technical, the steps are easy to perform:

  • Place the TV flat on a surface with the screen facing downward. It’s often more manageable if you remove the TV stand legs beforehand
  • Remove the screws around the TV, as well as the little screw found on top of the cable outputs
  • Lift the back cover of the TV off to see its various components

Trying both instances and testing to see if the connection issue is resolved seems a worthy option.

8) Use Ethernet Cable 

A handy troubleshooting option to try should you still be experiencing connectivity issues with your LG TV is to use an Ethernet cable between the TV and the WiFi router. This can be set up by doing the following:

  • Plug one side of the Ethernet cable into an available Ethernet Port on the back of the TV
  • Plug the other end of the Ethernet cable into an available port on the back of your router

Once successfully connected between both devices, you need to ensure the LG TV is now connected via a wired connection:

  • Turn on your TV
  • Open the ‘Quick Setting’ menu using the remote
  • Navigate to ‘Network’
  • Click on the ‘Wired Connection’ (Ethernet) option and you can confirm that the TV is connected to the Internet

Rebooting your router can solve many issues based on network and connectivity. Follow these steps to reboot your router: 

  • Unplug your router from its power outlet
  • Wait for approximately 60 seconds
  • Plug the router back into the power outlet
  • Allow the router one to two minutes to resync

Although a simple suggestion, rebooting your router can be an extremely efficient way to solve existing network issues.
