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

@michalOl For this to work, Deco mesh must run in Access Point mode. See Switching a Deco to Access Point (AP) Mode

@satrapal For Connection Preference feature to work and be available in Deco app, all Deco units in Deco mesh must have firmware that supports it. Your new M4R(EU) Ver.2.0, FW: 1.6.2 has firmware...

@SwatKat Yes, you can do that without any issues.
