Enable Guest Network in Deco app, it runs without the password by default.

I do not want to use Guest mode. I just wan to disable instead the wifi security

Hi

 

It is recommended that you go to Deco APP > More >Wi-Fi settings > click the Wi-Fi name > choose advanced >security type and change it to None or go to Deco app> MORE > Wi-Fi > tap the password box and you will be able to change the Security Type.
If you don’t see the none option, it is recommended that you follow method 1 of the link below to upgrade the firmware.
