This is a pair of Multiboard snaps that can be used to mount an Asus RT-AC3100 or Asus RT-AC88U to a Multiboard octagon plate. This makes a great wall mount.

1. Remove the rubber plugs from the key slots on the bottom of the router. You may have to use a toothpick or screw driver to get them started.
2. Place the snaps in the octagon plate 9 MU apart with the studs aligned vertically. The left snap has its stud on its right side, and the right snap has its stud on its left side.
3. Hang the router by its key slots on the studs. If the studs do not align with the key slots, swap the snaps and try again.

These snaps may also be compatible with the RT-AC3200, but I don't have access to one to confirm compatibility.
