The WRT1900AC was the first of the wrt_ac_series
to be released. It featured 4 detachable antennas, and a dual core
processor, and an internal cooling fan. It is a dualband, 802.11ac wave 1
(80MHz) capable device.
The second revision of the hardware removed the internal cooling fan and
made changes made to the way wifi power tables are loaded into the
device due to moves from Linksys in response to FCC changes. It also
changed to a new processor architecture.
