[edit] Performance

The dual core ARM CPU is beneficial for running multiple simultaneous services on the router.

SFE accelerated NAT was added to DD-WRT since build 33006 (kernel 3.10+), which Kong tested at 900 Mb/s throughput (download and upload). OEM firmware uses Broadcom's proprietary CTF (Cut-Through Forwarding).

  1. Throughput with IPv4 NAT routing tops out at:
    • 450Mb/s on latest Netgear stock firmware
    • 360Mb/s on non-SFE DD-WRT (default configuration)
    • 425Mb/s non-SFE with a 20% overclock
  2. For older builds, besides overclocking, using IPv6 and doing away with NAT is another workaround.

[edit] Features

  • Linux kernel 3.10.25
  • Supports CPU overclocking: 1200MHz and 1400MHz possible (be very cautious)
  • OpenVPN and PPTP VPN server support
  • Ad blocking with Privoxy
  • Other: lighttpd + php

[edit] How to install

See the K3-AC-Arm Readme file, but in short, if you're starting from the Netgear firmware, then download and flash the appropriate .chk file from the Initial directory using the Netgear web interface. Once it is installed, if there is a newer release than your .chk file, then download the appropriate .bin file, visit your newly installed DD-WRT router, head on over to its Firmware Update section and flash the .bin file, also selecting the option to reset to defaults. After that, you're on newest firmware, and good to go. Hint: if you're new to DD-WRT, the default IP address of your router after flashing or reset to defaults is 192.168.1.1.

Brainslayer and Kong build links can be found in the Firmware FAQ. Both are compiled from the main DD-WRT trac, but see Kong's Readme for minor differences. Brainslayer and Kong usually release builds at different times.

[edit] Documentation

Some of the generic DD-WRT documentation is also applicable to the R7000, but much of it is long out of date, and almost none of it refers to <Kong>'s K3-AC-ARM builds or the ARM architecture in general.

<Kong> has written some documentation specifically relevant to his builds, including:
