If you have reset your LG TV but now it’s not connecting to Wi-Fi, the most likely reasons are that the TV encountered a system glitch, or the TV’s Wi-Fi module is obstructed with dust and debris.
Masuma emailed Homespoiler:
Homespoiler, I have an LG Smart TV which I bought last year during the Black Friday sale! It’s quite impressive, and everything was working fine. However, this morning when I tried to watch my favorite show ‘Money Heist,’ I turned on the Wi-Fi, but it seems to not be connecting. My LG TV not connecting to wifi. I restarted both my TV and router, but no luck! What could be the issue when everything was working fine until yesterday?” —Masuma, New York
Masuma, this is not just you!
However, this problem is unfortunate and can happen at any time.
Let me break down the issue!
What’s your problem?
- ‘My LG TV is not connecting to WiFi suddenly, but it was working fine some time ago.’
- ‘I reset my TV, but after resetting, WiFi is not connecting.’
- ‘My LG TV is suddenly not finding any available WiFi networks to connect to.’
If you are having this issue suddenly or after a reset, temporary glitches, signal interference, or wrong WiFi password are most likely the cause.
But if your LG TV is not finding WiFi to connect or it says ‘WiFi is turned off”, then either the internal WiFi module has been damaged or clogged with dust.
OK, how to troubleshoot this issue?
Here are the detailed explanations;
Step 1: Perform an HDMI reset
Though you already rebooted both the TV and the router, I would recommend doing it again, but with a slight difference.
Because rebooting isn’t just enough to drain the power from the TV’s internal transistor/capacitor and reset it—only a power cycle/HDMI reset can do it..
- Disconnect the TV from the power outlet completely.
- Similarly, disconnect all the HDMI-connected devices from the TV.
- Now wait for 5 Minutes.
- During this time, press and hold the TV’s power button for about 20 seconds.
- Once done, power the TV back on.
Now check if you can connect your LG TV to the WiFi. If not, proceed to the next step
Tip: Do this after changing the location setting and turning off the ‘Quick Start‘ features. Because it will then be much more effective than before!
Step 2: Clean the WiFi module
TV has a separate component inside the motherboard.
It basically looks like a small circuit board or chip, which is responsible for catching the available WiFi signal and connecting the TV to it.
Just like a bridge!
However, here’s the catch: as time goes by, this little module tends to accumulate a fair amount of dust.
And you know how dust can be, right? It can cause all sorts of issues and mess with the module’s performance.
Look what this guy says:
“I just saved $800+ going to BB to get a new TV today. I searched the internet high and low, came across a lot of different videos and online articles but opted to try cleaning the network module and to my total shock, it works!!! Boo-yeah.”—

Also, be sure to check your TV’s time and date. Because time and date can hugely impact your TV’s ability to connect to the internet.
Step 3: Update the TV’s firmware
Most smart TVs automatically update when a new firmware version is released.
But you may have mistakenly turned off this, and that’s why your TV could not catch the update.
However, since there is no internet connection on your TV, you have to do it manually. Here’s an article on how you can update your LG TV via a USB flash drive. (Click here)
Step 4: Factory reset your TV
As the last option for troubleshooting, perform a factory reset.
This will return your TV to its default settings as if it were brand new.
Remember all saved settings you made on your TV will be permanently erased.
Here’s how to:
- Press the “Home” button on the remote.
- Go to “Settings.”
- Navigate to “All Settings“
- Next to “General“
- Finally, choose “Reset to initial settings.”
- Enter your security key if asked!
Your TV will start to get reset.
Wait sometimes, and then try reconnecting to the internet. I hope this method will work.
Conventional solutions such as restarting the TV or checking the password are often the first things that come to mind when troubleshooting this issue.
But, getting creative and thinking outside the box is sometimes important.
For instance, a signal booster can do the trick, or simply changing the channel on your router may resolve this issue.
Here’s how to do this:
- Log in to the router’s web interface using its IP address.
- Navigate to the wireless settings page.
- Choose a different channel from the available options
- Save changes.

The exact steps may vary depending on the make and model of your router, so some slight differences in the process may occur.
Q: I’ve entered the correct WiFi password, but my LG TV still won’t connect. What should I do?
Make sure you’re entering the WiFi password correctly, including any uppercase or lowercase letters.
If it still doesn’t work, try restarting your router and then attempt the connection again.
Q: My LG TV won’t even detect any WiFi networks after the reset. What should I do?
Ensure your TV’s WiFi adapter is enabled.
If it still can’t detect networks, there may be a hardware issue, and you have to disassemble the TV and then clean the WiFi module.

Q: Is there any way to access the internet without connecting to WiFi?
Yes, there is a way to access the internet without connecting to WiFi and that is by using an Ethernet cable.
That means going back to a wired connection. Although a wireless internet connection is fast, you cannot compare it to the stability of a cable connection.
However, this is not an ideal solution but can be used as a temporary fix until you find a more effective way to resolve the Wi-Fi connectivity issue.
Q. My LG TV keeps disconnecting from WiFi
The main culprit for this issue is a weak WiFi signal.
This can be caused by the router being too far away or interference from other electronic devices.
Here are the reasons why your LG TV keeps disconnecting from WiFi,
- TV’s WiFi receiver is not as strong as other devices in your home, so it has a more challenging time connecting to the network.
- The WiFi network itself is not as strong as it could be and is having trouble connecting to all devices in your home.
- Something interferes with the WiFi signal, such as another wireless device or metal furniture.
- TV’s software is outdated and needs to be updated.TV is not properly configured to connect to your WiFi network.
