 +*DO NOT UPDATE THE STOCK FIRMWARE TO A NEWER VERSION OR YOU MAY RISK A LOT OF EXTRA WORK. STICK TO STOCK BUILDS OLDER THAN 180125. 180125 will block your router from being able to update to any third party firmware. If your router is on this version or newer, you will need to follow this topic's instructions: https://forum.dd-wrt.com/phpBB2/viewtopic.php?p=1226430&sid=7a6b82e4ee39c42e668df2c336c267e0#1226430

[edit] How to install DD-WRT

[edit] TP-Link Archer C9 v1

  • Ensure you have latest firmware from TP-Link
  • Download factory-to-ddwrt.bin from the tplink_archer-c9v1 directory from one of the links here.
  • Read New Build and model-specific threads to determine the stability of a given build.

[edit] TP-Link Archer C9 v2

  • Ensure you have the latest firmware from TP-Link (tested with Archer C9(UN)_V2_160517)
  • Download factory-to-ddwrt.bin from the tplink_archer-c9v2 directory from one of the links here.
  • Read New Build and model-specific threads to determine the stability of a given build.
  • Upload the dd-wrt firmware using the standard TP-Link UI and wait until router reboots
  • Download the last appropriate dd-wrt firmware here
  • Upload the latest good webflash.bin build using the dd-wrt GUI found under Administration->Firmware Upgrade
  • DD-WRT v3.0-r30385 std (08/12/16) has been tested stable

WARNING: Enabling JFFS bricks the router: "That seems to nuke all the way up to 0xFEFFFF in the SPI flash."

  • TheDoc's fix for bricked v3/v4 is here.

[edit] Bricked Router

Symptoms: all the LEDs are ON, and you can't access to UI

Follow these steps:

  • Switch off the router
  • Download a complete binary-image of firmware
  • Rename the downloaded firmware with the following name: archerc9v1_tp_recovery.bin or "archerc9v2_tp_recovery.bin" if you have a v2 router
  • Serve as TFTP server the renamed firmware on the following IP: 192.168.0.66
  • Switch on the router, holding the RESET button for 2-4 seconds
  • The firmware will be automatically downloaded and installed by the router

Symptoms: after the dd-wrt installation the MACs are changed!

[edit] Recovery Mode

The v3 CFE has a built-in Webpage Firmware Recovery mode for bricked routers: see TP-Link article.
