When LG TV disconnects from WiFi, it’s safe to assume that there’s a problem on either your TV or router’s end. Stay with us, because we will review all causes and solutions for the issue!
Your LG TV may be randomly disconnecting from WiFi if there’s a problem with the router or modem’s network.
If connected to a 5GHz network or when “Quick Start+” is enabled, your LG TV could also experience random disconnects due to inconsistency in the WiFi.
Let’s keep reading!
Why Does LG Smart TV Disconnects From WiFi?
Here are the most frequent reasons why LG TV disconnects from the WiFi:
- An issue with the network equipment
- Improper WiFi connection frequency
- An issue with the LG TV software
- Incorrect LG TV settings are enabled
- The router is too far away from the TV
- Your router’s WiFi channels are crowded
- There’s a problem with your router/modem!
Does LG TV Disconnects From WiFi When Turned Off?
Your LG TV is configured to disconnect from WiFi when turned off, in order to preserve network resources.
If there’s a registered WiFi network that you’ve entered the credentials and have been connected to, the LG TV will attempt to automatically connect every time when turned on.
8 Fix Methods When LG TV Disconnects from WiFi?
Tip: Follow our steps in chronological order!
1. Connect to a 2.4GHz Frequency
Whilst 5GHz WiFi could offer greater internet speeds, the regular 2.4GHz frequency has a larger range and is more prone to interference.
Thus, when using the slower but more reliable and consistent 2.4 GHz frequently, your LG TV shouldn’t randomly disconnect.
How to Check if I Have 2.4Ghz Frequency?
The 2.4GHz WiFi is the standard thread for all Wi-Fi routers. Only dual-band network devices can host up to 2 networks, including a 2.4 GHz thread and a 5 GHz thread.
You should be able to check your router’s available networks at Router GUI > Networks > “Threads” or “WiFi”.
How to Connect LG TV to a 2.4GHz WiFi:
- Press the “SMART” button on your LG remote.
- Scroll down and access the Home menu.
- Select the “Settings” button, then press “OK”.
- Choose “Network” then “WiFi Connection”.
- Wait for your TV to discover all networks.
- Select your router’s 2.4GHz WiFi thread.
- Insert the password and press “Connect”.
2.4 GHz Vs 5 GHz in Terms of Coverage:
- 2.4 GHz – more lightweight signal, travels freely through obstacles, up to 150 meters
- 5 GHz – stronger and bulkier signal, easily interfered with, travels up to 50 meters
Info: Once your TV is connected to the 2.4GHz WiFi band, you may see a slight reduction in the internet speeds if you were connected to 5GHz until now!
2. Deactivate “Quick Start+” On LG TV
Though the “Quick Start+” feature may help with launching your TV faster, it could cause interference with the TV.
LG televisions are set to automatically connect with a WiFi network upon turning on, but “Quick Start+” may deactivate WiFi whilst the TV is in standby mode.
Here’s how to turn off “Quick Start+” on your LG TV:
- Press the Settings (cog icon) button on your remote.
- Scroll down in the tab and navigate to “All Settings”.
- Press on “General” once you reach the page.
- Press “down” until you highlight “Quick Start+”.
- Press “OK” on your remote to push the slider to the left.
Tip: In case the feature is disabled, simply toggle on Quick Start+ and then toggle the option off.
3. Perform a “Power Cycle” on your TV!
To refresh the software of your LG TV and address any functionality and software problems, we strongly recommend the power cycle process.
This is the advanced way to reboot any device and perform a power circulation, which refreshes all services and LG TV operational tasks.
Here’s how to “power cycle” your LG TV in easy instructions:
- Use the remote control to shut down your LG TV.
- Wait for the television to power off completely.
- Unplug the power cable of the LG TV from the source.
- Wait for 5 minutes while the LG TV is unplugged.
- Reconnect the power adapter of the TV to power.
- Turn on the LG TV and check the WiFi connection.
Info: The power cycle will not only discharge your LG TV but also help with overheating issues, especially during the warm seasons!
4. Optimize WiFi & Solve Interference!
One of the most important steps, when any smart TV or LG TV is disconnecting from the WiFi, is to check for any WiFi inconsistencies and interference.
Perhaps the location of your LG TV is a “dead WiFi zone” in your home, caused by various appliances.
To optimize your WiFi so the LG TV can be constantly connected you would need to relieve some bandwidth by disconnecting unused devices.
In addition, any high-bandwidth tasks such as downloading or uploading are also responsible for WiFi inconsistency on other devices.
Some of the appliances and objects that can actively cause WiFi interference wireless devices such as antennas, Bluetooth receivers, and baby monitors.
Tip: Use your smartphone to test the WiFi while staying as close as possible to the LG TV.
5. Alter the WiFi Channels!
If your router’s channels are too crowded, your router/modem may automatically unpair devices to save network resources and bandwidth.
Setting your router to send out information in the less-crowded channel can greatly improve the reliability and strength of the connection!
- To adjust your router’s channels, you must sign in to the router’s GUI
What is Router’s GUI?
All routers have a local host where users can enter and tweak the router’s settings on a connected device using an online browser.
Hence you would need a computer, laptop, or smartphone, connected to the WiFi or via Ethernet to your router in order to access the panel.
Info: By default, the login credentials are “admin” for both username and password!
How to Access Router GUI:
- Insert “http://192.168.100.1/” into your online browser.
- Test logging in with admin/admin or admin/password.
- In case you can’t log in, use the password on the sticker.
- Access the “Advanced” > Wireless Settings of the router.
- Locate and select the 2.4 GHz wireless network thread.
- Select Change WiFi Channel and switch to another channel.
Feel free to test with multiple WiFi channels until your LG TV stops disconnecting.
In addition, there are “WiFi Analyzer” apps in the Google Play or App Store that allow checking how crowded the different WiFi channels are when your phone is connected to your router.
Note: Your router doesn’t need to be restarted to apply the change of the WiFi channel.
6. Restore Initial Settings On LG TV!
If your LG TV is still failing to maintain a WiFi connection, it’s time for a factory reset.
It’s likely that your TV has encountered some critical software faults and the best course of action is to wipe the software clean and then check if the TV would still disconnect from WiFi.
- Performing a factory reset on your LG TV will erase all content and data!
Follow these instructions to restore the initial settings of your LG TV:
- Bring up the menu page using your LG TV remote.
- Open the “All Settings” tab from the menu page.
- Navigate to the “General” tab using the remote.
- Press on “Reset to Initial Settings” next.
- Scroll down and choose “Revert to factory settings”.
- Follow the on-screen prompts to factory reset your TV.
Alert: Once the factory reset takes place, do not interact with your TV in the upcoming minutes, since canceling the process midway might impact the process.
7. Use Wired Connection (Workaround)
In case your LG TV keeps disconnecting from the wireless network and you’re unable to solve the issue, there is a solution.
In case you didn’t know the LG smart TVs are equipped with an Ethernet port on the back panel, where you can connect to your router via an Ethernet cable.
The Ethernet cable should be plugged into an (enabled) LAN port (yellow color) on your router and the other end into the Ethernet port on your LG TV.
Then you need to use the remote and press the SMART button to navigate into Settings > Select Network > Network Connection.
Note: The wired connection is not an object of external interference!
We’ve learned that when LG TV disconnects from WiFi, the best solution is to power cycle the TV and deactivate the “Quick Start+” feature.
If the issue persists, troubleshoot your router by rebooting the device and adjusting the WiFi connectivity channels!
