I built my own wi-fi stand with 7€ worth of hardware store supplies. It fits nicely to my 30€ nondescript tripod for my AP on a stick surveys.
It’s basically a 1000mmx25mmx1mm steel strip, bent in a rectangle and bolted fast to an iron plate. It is slightly wider than the usual 23.8mm (15/16″) ceiling rail.
In horizontal mount position, heavier APs like this Extreme Networks 3935 are a bit wobbly, but stable nonetheless.
The vertical position is done rotating the mount and attaching the AP sideways.
I can even fit an outdoor AP 3965 with its heavy mounting plate.
I simply hang the outdoor AP 3965 using the mounting plate and the pole mount straps. I insert the stand above for safety reasons, and use work gloves for handling the AP because of the pole-mount sharp edges.
This wifi stand may not be stylish or refined, but it’s very practical!
