So I have an AC1200 Deco wireless mesh setup and right now I only have 1 of the 3 units being used, when we move I'll set up the other two. So it's a pretty simple arrangement.

I had to unplug my router and modem to move them to a different spot in my apartment, but having them unplugged for LITERALLY 3 minutes made my TP link setup lose everything. 
 

it basically made me go through the entire process of naming my network, linking everything up again, all of it. 
 

The only thing the app saved was my login info, that's it. This CANNOT be how it normally operates... so if I lose power for just a few minutes is my TP Link setup going to need to be set up again??
