Overview[edit]

1300 Mbps - 3SS 5GHz 802.11ac (80MHz chan.),
450 Mbps - 3SS 2.4GHz 802.11n (40MHz chan.) = 1750 Mbps class

"U12H332T78" is in the header of the firmware file that is available for download.

Broadcom chips are just a guess, for now. This device is presumed to use BCM4360 + BCM4331 radios like the Netgear R6700v3 / Netgear R6400 v2 since no MU-MIMO or 256-QAM support is claimed in any currently available PR.
