Overview

1900 Mbps - 4SS 5GHz 802.11ac (80MHz chan., 256QAM),
750 Mbps - 3SS 2.4GHz 802.11n (40MHz chan., 1024QAM) = 2650 Mbps class

"FAST5280CH/MB REV:1.03A" is silkscreened on the main board.

Also known as Sagemcom RAC2V1S.

The user manual is branded for Spectrum Cable.

A daughterboard with both Wi-Fi radios connects to the main board using a PCIe x1 slot.

This daughterboard has "FAST5280CH/WIFI REV:1.04" silkscreened on it.

An FCC filing available 09/19/2017 was requested to be dismissed.

A new filing was available on 09/26/2017.
