Hi, currently, the last firmware of UK version has already supported disabling the UPNP, and changing the security mode;

As for the WPS, since there is no hardware on/off button on the Deco, only software button on the Deco APP and it is in-active by default, needs to be activated on the APP;

Please refer to the attached pictures to see whether this WPS setting is ok for you.

Thank you.

Hi, it is ok to connect a PoE switch to the 2nd Ethernet port of the main Deco;

As for the 2nd question, Did you talk about the technical support service time?

--If yes, there is no time limitation of the technical support, and as long as you are interested in our product, you are free to ask questions;

Thank you very much.
