So I know the app will apparently present VLAN ID option for the Guest Network when you have the Deco units wired together. https://www.tp-link.com/us/support/faq/2317/

My question, does it work when 2 of them are wired and 1 is wirelessly uplinked as well?

Trying to plan a network reconfiguration and I can easily get 2 units wired, but 1 is not really possible, and frankly doesn't really need the bandwidth of wired back haul.

 

P.s. can the absolutely horrible fourms based spell check be disabled, it sucks and prevents Chrome and im sure other browsers from providing thier MUCH better spell checker.
