[LG Air Conditioner ThinQ] LG ThinQ connection is failed. It says failed registration.

Troubleshooting

Try this

Before registering the product, check the router and smart phone setting.

On the smart phone, turn off [Mobile Data].

The product’s Wi-Fi is not connected to the internet, so go to the smartphone setting, and deactivate Mobile Data Auto Switching.
Turn off the mobile data and set up an internet connection with the WI-Fi signal and then register the product.
* iPhone : Setting → Cellular → Cellular Data

Check if the ‘Wi-Fi Auto On’ and the ‘Switch to Mobile Data’ settings are activated.

Deactivate the ‘Wi-Fi Auto On’ function and the ‘Switch to Mobile Data’ function.
(Different items exist depending on the model of mobile phone from each maker, thus refer to the company guides.)
The setting is used for ThinQ connections only, so after making a connection, revert it to the original setting.

Android : Setting → WiFi → Advanced → Disable Wi-Fi Auto-On

iPhone (IOS) : Setting → WiFi → Disable network connection request

Check if the Wi-Fi router supports the frequency band of 2.4GHz.

ThinQ app supports the 2.4GHz Wi-Fi band.
Since ThinQ is not supported in the 5GHz environment, select the one without “5G” or “5GHz” in the network name.
If it is hard to check the frequency for the wi-fi router used, then ask your internet service provider.

Check if the router name (SSID) or password contains special characters.

Check if the router name or password contains special characters. [Ex: ★, ●, ♥ and etc]
If there are special characters in it, then change the router name or password.
(Except for Korean and figure type special characters, combine special characters on the keyboard !@#$%∧&()_+| and etc] as well as alphanumeric letters.)
Delete the registered product and register it again.

Check the security type of your router.

→ For your router’s security type, you are recommended to use WPA/WPA2 and you cannot access ThinQ with WEP, WAP3 and so on.

Check if ThinQ App is in the latest version.

→ If the app is not in the latest version, then update it first before registering it.

If the registration keeps failing, then check the following.

Note
Due to temporary tx/rx failures, the product registration might fail.
Remove the power plug for the router and the product and wait for about one minute and then reconnect the power supplies and try again.
If the registration with the mobile phone fails, then use another mobile phone for registration.
(If the registration is successfully done with other mobile phone, then it is not the problem with the product.)
Check if the password is inputted correctly.
After checking the password accurately, register the product again.
Password inputs are case sensitive.
Check the distance between the router and the product.
If the product is far away from the router or they are blocked from each other with walls and so on, then the signal will be weaker and connections will fail or be unstable.
Move the router to the location near the product.
If the error persists, then use hot spot(tethering) for a connection.
After disconnecting the router (wi-fi) connection, prepare two mobile phones and enable the hotspot (tethering) of one phone and complete product registration.
If registration is made in the hotspot (tethering) environment, the issue can be seen as caused by the router.
