Your home appliance and 
smartphone is not connecting to 
the Wi-Fi network.

you are trying to connect to is 
incorrect.
 • Find the Wi-Fi network connected 
to your smartphone and remove it, 
then register your appliance on LG 
SmartThinQ application.
Mobile data for your smartphone 
is turned on.
 • Turn off the Mobile data on your 
smartphone before registering the 
appliance.
The wireless network name (SSID) 
is set incorrectly.
 • The wireless network name (SSID) 
should be a combination of English 
letters and numbers. (Do not use 
special characters.)

GHz.
 • Only a 2.4 GHz router frequency 
is supported. Set the wireless 
router to 2.4 GHz and connect the

with your Internet service provider 
or the router manufacturer.
The router is too far from the 
appliance.

router, the signal may be weak 
and the connection may not be 
configured correctly. Move the 
router closer to the appliance 
or purchase and install a Wi-Fi 
repeater.
