[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

The primary Brainslayer and alternative Kong build links can be found in the Firmware FAQ. Both are compiled from the DD-WRT trac SVN, but Kong builds are deprecated (see Documentation for differences).

[edit] Flash from OEM

GUI reset then download and flash the .chk (trailed) file using the Netgear web interface*.

  • factory-to-dd-wrt.chk for normal builds
  • R7000.chk for Kong builds

[*] Newer Netgear firmware ( and newer) prevents GUI downgrades, preventing DD-WRT installation (K3_R7000, build from 9/23/18 file has a lower version number, 1.0.5* that Netgear disallows). Until a new Kong .chk image is available, use this mod version which provides a larger version number (thanks to @jclehner)

  • Alternatively, use the TFTP installation method

[edit] Upgrade from DD-WRT

Use the DD-WRT GUI or other installation Methods to flash the .bin (non-trailed) file

  • webflash.bin for normal builds
  • K3_AC_ARM_STD.bin file to flash from the GUI Administration -> Firmware Update section.

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Some generic DD-WRT documentation is applicable to the R7000, but much is outdated and little refers to ARM builds.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