"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.
