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.

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

How to install

Brainslayer and Kong build links can be found in the Firmware FAQ. Both are compiled from the main DD-WRT trac SVN, and are released asynchronously. Kong builds have minor differences, as the internal build suffix "M" designates.

If using Netgear firmware, download and flash the R7000 .chk file from the K3-AC-Arm directory using the Netgear web interface*. If running DD-WRT, then use the K3_AC_ARM_STD.bin file to flash from the GUI Administration -> Firmware Update section.

  • R7000's are now (as of March 2019) preventing downgrades from the current Netgear firmware (1.0.9.64_10.2.64 as of this writing) which prevents the current (K3_R7000, build from 9/23/18).chk file from being uploaded via the Netgear web interface (this chk file has a lower version number, 1.0.5* that Netgear disallows). Until a new Kong chk image is available, you can use this mod version [1] that works around the issue by providing a large version number (thanks to @jclehner)

Documentation

Some generic DD-WRT documentation is applicable to the R7000, but much is outdated and little refers to ARM builds.

<Kong> has written some documentation relevant to his builds [now via archive.org]:
