Like all computers, your LG smart TV runs software that over time can develop bugs or compatibility issues causing problems like WiFi connectivity failures.

Checking for and installing the latest firmware updates for your LG TV is a quick fix – new updates patch bugs and optimize connectivity capabilities.

Navigate to your TV’s settings menu and look for a “System Update” or “Check for Updates” option. This will scan for the newest firmware available from LG and download it directly on your TV if an update is available.

Major firmware updates take around 15-20 minutes to fully install. Be patient and let the process complete. Once updated, reboot your LG TV and router. Try reconnecting to WiFi to see if the new firmware resolved the connectivity problems.

#6 – Adjust DNS Server Settings on Your LG TV

Domain Name System (DNS) servers act as the “phonebook” for the internet, translating URLs into numeric IP addresses. By default your LG TV uses your internet provider’s DNS servers.

Switching to free public DNS servers like Google DNS ( / or Cloudflare DNS ( / could potentially fix WiFi connection issues caused by problems or congestion with your ISP’s default DNS servers.

On your LG TV, access the network settings menu, select your wireless network connection, and look for DNS server or IPv4 settings. Switch from “Automatic” or “ISP Default” DNS to use “Manual” or “Custom”.

Then enter the public DNS servers – either Google or Cloudflare depending on your preference. With new DNS servers assigned, reboot your LG TV and router. This simple change of DNS can resolve some connectivity problems.

#7 – Factory Reset Your Wireless Router

Resetting your WiFi router to its original factory default settings clears out any problematic misconfigurations or settings that could be preventing connectivity between it and your LG TV.

The reset button is typically located on the back or bottom of your router marked as “Factory Reset”. You’ll need something small like a paperclip to press and hold the recessed button for 10-15 seconds until the router powers off and reboots itself.

Run through the initial setup process for your newly reset router, re-entering your wireless network name (SSID) and password to reconnect devices like your LG TV. This often resolves router-related connectivity issues.

Just be sure to backup your router settings beforehand so you have all the details to reconfigure things later!

#8 – Update Your Router’s Firmware

As mentioned earlier for your LG TV, having outdated firmware on your wireless router can also introduce WiFi connectivity bugs and compatibility issues.

Log into your router’s administrative settings interface to check for any new firmware update files available from your router manufacturer. This may require looking up your router model on the vendor’s website.

Follow the instructions to carefully update your router’s firmware to the latest version available. Take your time and let the process complete.

Once updated, you’ll want to restart both the router and your LG TV. Apply firmware updates can resolve router glitches interfering with connectivity to devices like your smart TV.

#9 – Change Your Router’s WiFi Channel Setting

In densely populated areas, interference from nearby WiFi networks and devices can sometimes disrupt connectivity for your LG TV.

The solution is to change your router’s wireless channels to use a different frequency band that has less interference. This is like switching “lanes” to avoid traffic.

Access your router’s wireless settings, and look for the channel settings for the 2.4GHz and 5GHz networks. Try changing the channel to a lower interference option like 1, 6, or 11 on the 2.4GHz band.

On 5GHz, pick a lower DFS channel between 36-48 for the best performance. Save settings, reboot your router and TV, and check if connectivity improves after the channel change.

#10 – Relocate Your Wireless Router Closer to Your LG TV

If your WiFi router’s location is too far away or blocked by multiple walls from your LG TV, the wireless signal may simply be too weak. Weak signal equals spotty or no connectivity.

Try temporarily relocating your router much closer to your TV to see if proximity alone improves the WiFi connection strength and stability. Place the router within a direct line of sight of the TV if possible.

This quick test will confirm if weak signal is the root of your LG TV’s connectivity frustration. If so, you can look into relocating the router permanently closer, running ethernet cabling, or installing WiFi extenders to amplify the signal strength.
