LG TV unknown device disconnected problem occurs due to a problem in the WiFi or Bluetooth card. Disconnect both connections and use an ethernet cable to get internet connectivity. If your TV is under warranty, you can claim it to get a card replacement.
However, I have shared some quick fixes that you must try before claiming the warranty or calling a technician.
How To Fix LG TV “Unknown Device Disconnected”
Without further ado let’s get started to get rid of the issue.
1. Power Cycle Your LG TV
Power cycling your TV ends all the ongoing processes, including WiFi or Bluetooth-based pairings.
Follow these steps to power cycle your LG TV.
- Unplug your TV from the power socket.
- Remove all the peripheral devices such as streaming players, speakers, USB, etc.
- Wait for a few seconds to let your TV’s capacitors discharge fully.
- Plug in your TV again.
- This will hopefully resolve your LG TV error.
2. Reset Your TV WiFi Connection
The LG TV WiFi connectivity issues could be because of network, therefore, resetting your WiFi connection can be a possible solution.
- Unplug your WiFi router from the electrical socket.
- Wait for at least 60 seconds.
- Re-plug the cable of your W-Fi router.
- Now reconnect your TV to your WiFi.
Rebooting your WiFi router is a viable solution for several reasons.
Firstly, it removes glitches from the internet settings on your TV. Secondly, it improves signal strength and removes the chance of sudden disconnections.
3. Swap to Ethernet Cable
If your LG smart TV is connected to WiFi, another option for fixing the device connection problem is by swapping over to an Ethernet cable.
Ethernet cables offer better signal strength, network speed, and reliability. It makes it nearly impossible for your internet connection to falter or get compromised. In addition, it prevents your TV’s WiFi functionality from working, deterring the device’s disconnection message.
Note: While Ethernet cable offers a reliable internet connection, be ready to make the tradeoffs such as lost portability and limitation to only connection.
4. Problem With The WiFi Module
While isolating the source of “unknown device disconnection” on an LG TV can be challenging, hardware failures, particularly issues with the WiFi module, may be a cause.
Even if your LG TV WiFi module isn’t malfunctioning per se, it may sometimes be incompatible with your WiFi network. As a result, you can experience device disconnection pop-ups, rather than more helpful warnings.
Sometimes, repairing or just clearing the WiFi Module can eliminate your LG TV error, so be sure to discuss these suggestions with your technician.
5. Refresh Your TV’s Bluetooth Connection
Though, it is very rare for Bluetooth connections to act up, that’s exactly why they are often overlooked. By connecting and disconnecting your Bluetooth devices, you can potentially resolve this issue.

- Wait for the audio to play through the connected speaker.
