• 2167 Mbps - 4SS 5GHz 802.11ac (80MHz chan., 1024-QAM),

• 1000 Mbps - 4SS 2.4GHz 802.11n (40MHz chan., 1024-QAM) = AC3100 class

Overview

"RT-AC3100 REV 4.07" and "1519" is silkscreened on the main board.

DFS certification and VHT80+80 support were added with a C2PC request on 3/6/2019. Actual support would probably need to come from a firmware update. The first page of the DFS Test Report lists two manufacturers: Askey and Compal.

• Differences between the three models covered by this FCC certification are described in the DFS Test Report as follows:

Model No.	LAN Port	Heat sink color
RT-AC88U	8 LAN ports	Silver, Red
RT-AC3100	4 LAN ports	Silver, Black
RT-AC88R	8 LAN ports	Silver, Red
