Is it me perhaps, but I've found that resetting my Deco XE5300 3 units very fickle. I had to swap two units because of a bad port on my main unit, per the instructions very easy, and it just never came back easily when I picked a new Main and swapped, was all very confused.

Had to remove and reset everything. Totally unclear how to reset the units exactly, TP-Link just says "reset unit" without specifics. I tried with the bottom reset button alone, power in/out, a combo of both, hold for 30 secs, etc. It's only after fiddling for 1/2 hour or more will the unit finally shows up to be added in again to my network (shows in Wifi as Deco_3B5A as an example). But man, not easy and no tech document on it. Got everything back and settings adjusted, but man, took a few hours of fiddling and I've had this problem before.

Can anybody shed light on this?
