2x Airport Extreme 802.11ac Routers (One 12TB) - $80 (San Francisco)

One unit is a 12TB storage HDD that can be used as a NAS or with Time Machine.
The other has no storage.
They can easily configured to operate as an extended Wi-Fi network.
Come with the mounting brackets.
You’ll need to get the double-barrel AC cord, I do not have them.
They are fully functional and was using them until I upgraded to a different brand of routers.
