Overview[edit]

4804 Mbps - 8SS 5GHz 802.11ax (80MHz chan.)
1148 Mbps - 4SS 2.4GHz 802.11ax (40MHz chan.) = AX6000 class

As with other similarly specced products, this device only supports 80MHz channel bandwidth when operating with eight spatial streams. It may support 80+80 or 160MHz channels by dropping down to four spatial streams.

"D9TGQ" Micron FBGA code on the RAM corresponds to the MT40A256M16GE-083E:B
