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