I don't want my ac86u in the basement closet so I wall mounted it outside the closet with two clothes hangers. The main hanger has a horizontal bar that can be unhooked so I ran that through the space behind the clear plastic with the asus logo. The other hanger is just to keep it pointed horizontally.
If only asus added mounting holes so I could just add two screws to the door and be done.
