Check What Is Causing the Problem
Before making any changes, it helps to narrow down where the issue actually is. A Wi-Fi connection that drops repeatedly can come from the TV itself, your home network, or interference in the environment. Try these quick checks first:
- Does the issue affect only the TV? If other devices like phones, laptops, or tablets stay connected without problems, the TV is the likely source.
- Does it happen at specific times? Intermittent disconnections during peak hours may point to network congestion or router overload.
- Does the TV lose connection to all networks or just yours? If it cannot see or stay connected to any Wi-Fi, the wireless hardware or software on the TV may be at fault.
- Are you far from the router? Distance and obstacles like walls, floors, and large appliances can weaken the signal significantly.
Identifying these patterns will help you apply the most effective fix without changing settings unnecessarily.
Fixes to Try in Order
1. Restart the TV and the Router
A simple restart clears temporary glitches on both devices. Start by unplugging your LG TV from power. At the same time, unplug your router and modem. Wait at least 60 seconds before plugging the router and modem back in. Let them fully restart — this usually takes two to three minutes. Then plug the TV back in and turn it on. Check whether the connection remains stable.
This fix resolves many transient problems because it forces both devices to re-establish the connection from scratch. It also clears any temporary IP address conflicts that may cause disconnections.
2. Forget and Reconnect to the Wi-Fi Network
If restarting did not help, the saved network profile on the TV may be corrupted. Removing it forces a fresh connection. Go to the TV settings menu, select Network, and then Wi-Fi Connection. Find your network name, select it, and choose Forget or Delete. After that, scan for networks again, select yours, enter the password, and reconnect. Test the connection over several hours to see if the problem recurs.
3. Move the Router Closer or Reduce Interference
Distance and physical obstructions are common causes of intermittent Wi-Fi. If possible, place the router in the same room as the TV and keep it at least a few feet away from other electronics, metal objects, and thick walls. If moving the router is impractical, consider whether there are large appliances, mirrors, or fish tanks between the TV and the router. Even cordless phones, baby monitors, and microwave ovens can interfere with Wi-Fi signals.
On the TV itself, avoid placing the rear panel directly against a wall or inside a closed cabinet, as this can block the internal antenna.
4. Switch Between 2.4 GHz and 5 GHz Bands
Most modern LG TVs support both 2.4 GHz and 5 GHz Wi-Fi bands. The 2.4 GHz band travels farther and passes through walls better, but it is also more prone to interference from other household devices. The 5 GHz band is faster and less crowded but has shorter range.
To switch bands, you may need to rename the bands separately in your router settings (for example, adding “-5G” to the 5 GHz network name) so the TV sees them as two different networks. Connect the TV to the band that works best in your location. If disconnections happen on 5 GHz, try switching to 2.4 GHz. If they happen on 2.4 GHz, try 5 GHz.
5. Update the TV Firmware
LG periodically releases firmware updates that fix known bugs, including Wi-Fi stability issues. To check for updates on your LG TV, open Settings, go to Support, and select Software Update. Choose Check for Updates. If an update is available, install it and let the TV restart. Keep the TV connected to the internet during the update process. After the update, test the Wi-Fi connection again.
6. Change the DNS Settings on the TV
In some cases, the default DNS server provided by your internet service provider may cause intermittent disconnections. Changing to a public DNS server can help. To do this on an LG TV:
- Go to Settings and then Network.
- Select Wi-Fi Connection.
- Choose your connected network and select Edit.
- Change the DNS setting from Automatic to Manual.
- Enter a public DNS server address, such as 8.8.8.8 for the primary and 8.8.4.4 for the secondary (Google DNS), or 1.1.1.1 and 1.0.0.1 (Cloudflare DNS).
- Save the settings and reconnect.
This change does not affect other devices on your network. If it helps, the issue was likely related to DNS resolution timing or server unavailability.
7. Disable Quick Start+ or Power Saving Features
LG TVs have a setting called Quick Start+ that keeps the TV in a standby mode for faster booting. In some cases, this feature can interfere with network connectivity after the TV wakes from standby. To disable it, go to Settings, then General, and find Quick Start+ (the exact menu name may vary by model). Turn it off and restart the TV. Similarly, check for any energy-saving modes that may turn off the network interface when the TV is idle. Disable those as well and test the connection.
8. Reset the TV Network Settings
If nothing else has worked, resetting all network settings on the TV can clear deeper configuration problems. Go to Settings, select Network, and look for an option labeled Reset Network Settings or similar. Confirm the reset. The TV will restart and clear all saved Wi-Fi networks and connection data. After the reset, set up the Wi-Fi connection from scratch.
If the Problem Continues
After trying all the steps above, the issue may lie with the TV hardware itself or with your router. If you have access to another router or a mobile hotspot, connect the TV to that network temporarily. If the connection is stable on a different network, the problem is likely with your primary router or internet service. In that case, restarting the router in a more thorough way (factory reset) or contacting your ISP may help.
If the TV still disconnects from every network you try, the internal Wi-Fi module may be faulty. Check whether your TV is still under warranty and contact LG support for further assistance. They may offer a repair or replacement depending on the model and warranty status.
Frequently Asked Questions
Why does my LG TV keep losing Wi-Fi but other devices work fine?
This usually points to a problem on the TV itself, such as a corrupted network profile, outdated firmware, or interference specific to the TV’s location. It can also happen if the TV is using a weak Wi-Fi antenna or if Quick Start+ is interfering with the connection after standby.
Does using a wired Ethernet connection fix the issue?
Yes, connecting the TV directly to the router with an Ethernet cable bypasses Wi-Fi entirely. If the connection is stable over Ethernet, the problem is definitely related to the Wi-Fi hardware, settings, or environmental interference.
Will a factory reset of the TV solve the Wi-Fi problem?
A full factory reset will erase all settings and installed apps, returning the TV to its original state. This can fix persistent software-related issues, but it should be your last resort because you will need to set everything up again. If the problem is hardware-related, a factory reset will not help.
Can other electronics near the TV cause disconnections?
Yes. Devices that emit radio frequencies, such as cordless phones, microwave ovens, baby monitors, and even some LED lights, can interfere with Wi-Fi signals. Moving the TV or router away from such devices may improve stability.
