Inside Actiontec MI424-WR Rev F

Specifications of Actiontec MI424-WR Rev F:

Processor

MIPS64 Architecture
64-bit dual core
Cavicu, Octeon Plus CN5020
Cpu id 0xd0601
USB 2.0, high-speed (480 Mbps), host with integrated PH
Integrated CoProcessor for processing of IPsec, SSL, DH, SRTP, WLAN security,DES, 3DES, AES (up to 256-bit including GCM),SHA1, SHA-2 up to SHA-512, RSA, ECC, KASUMI,and Data-at-rest security (AES-XTS)
Maximum instructions per second: 2.8B
Requires a 700MHz graded part with and 700MHz CPU clock. Cavicu has this part in 300, 400, 500, 600, and 700MHz rated parts.  This is just like when you buy an Intel CPU (i.e, IvyBridge Core i5) and you can pick different frequencies for the CPU.  Over-clocking might be an option, but the heat-sink of the CPU needs to be beefed up and/or it will need a fan to be cooled down.
Per Stock firmware, the CPU is clocked at 500 MHz - see the page on telnet investigation..
Secure Communication Processor: Includes, encryption, networking, TCP acceleration and QoS.  See the CPU block diagram for more info.

Nanya NT5TU32M16DG-3C (datasheet)

Ethernet Switch Hardware

Marvell 88E6061
6-Port Fast Ethernet Switch (10/100) w/ QoS
Note: Only 4 ports are available for networking as this board is desigend with 4 PHYs and 2 MII configuration
802.1Q support: 16 VLANS
QoS IEEE 802.1p
Priority, 4 Queues per Port
MAC Size: 1K
Pin compatible with 88E6060 (80E6060 datasheet)


Wireless

Atheros AR9227-BC2A
802.11b, g, n
MIMO 2x2 chip, one antenna installed.
Only one antenna is installed. 2x2 needs additional parts to be added.  For FCC testing, the router was also tested with two antennas.  Internal pictures in the filing shows the setup.  The board as shipped out of the factory is missing the matching network parts for one of the antennas, but the other side is already populated.  The antenna cable also has a matching network on it which are shrunk wrap.
Frequency (per FCC application): 2.4120 - 2.4620 MHz

Coaxial Network Controller

MoCA 1.1 certified
Native DLNA support
250 Mbps PHY


FCC ID

LNQMI424WRF
