LG Air Conditioner WiFi Blinking – Quick Fix

If the WiFi in your LG air conditioner is blinking, ensure the connection is still strong. Press the WiFi button until it turns off. Next, turn the WiFi off and on again. If it is a portable air conditioner, press the Fan button and hold it for about three seconds or until the WiFi icon begins to flash. On some models, you will need to press the Mode and fan buttons to activate WiFi. a few models require you to press the Jet mode and Energy Saver buttons for the WiFi activation. Consult the user manual for steps to activate WiFi on your specific model.

The blinking you see may be that you need to register the unit or reconnect to WiFi. If there is a disconnection and the WiFi is idle, it may start blinking. There may be an obstruction between the router and the air conditioner, cutting off the connection. Also, ensure the password is correct.

Turn off the WiFi and disconnect it from your phone or any other device. Next, turn it on again and reconnect it through your phone. This time, make sure there is a seamless flow between the unit and the router and enter the correct password. If nothing else seems to work, contact LG Support Center to report the issue and request service.

The WiFi name and password may have changed. This happens if you are not the only one with access to the router. Therefore, it helps to double-check the name and password; if they have changed, use the new details to reconnect the air conditioner to your WiFi.

Furthermore, using the router to access live videos or to operate CCTV weakens the signals and leads to disconnection. If you use CCTV or stream live videos, you may want to get and install another router to lessen the load. That way, all the data does not go to one router to weaken its signal.
