Installation

  • NOTE: Do NOT upgrade the firmware via wireless connection unless the TP-Link device only has wireless connection.

TP-Link Archer C9 v1

Prerequisites

  1. Ensure you are on the firmware version 161008 from TP-Link (direct download link)
  2. Download factory-to-ddwrt.bin from the tplink_archer-c9v1 directory from one of the links here.
    • E.g. build 04-05-2016-r29409 factory-to-ddwrt.bin
    • Optional: Download archer-c9v1-webflash.bin from the current release directory if you used the above file for initial flash.
    • See "Upgrading DD-WRT" for upgrade procedure.
    • Pro Tip: Read New Build and model-specific threads to determine the stability of a given build.

Procedure

  1. Connect your PC to one of the LAN ports on your router with an ethernet cable.
  2. Open a browser and go to http://tplinkwifi.net (or http://192.168.0.1 if you have not changed default IP).
  3. Go to Advanced -> System Tools -> Firmware Upgrade
  4. Under Local Upgrade click Browse and locate the previously downloaded factory-to-ddwrt.bin file and click Open.
  5. Click the Upgrade button. The device will reboot automatically after the upgrading has been finished. Please wait about 3-5 minutes.
    • NOTE: Do NOT turn off the power or disconnect the Ethernet cable during upgrade process.
  6. Once the router has rebooted completely, ensure your PC has an IP address in the 192.168.1.0/24 subnet range.
  7. In your browser, go to http://192.168.1.1 where you should be greeted by the DD-WRT password change page in the WebUI.
  8. Set a simple password for now, click on Change Password.
  9. Do a normal reset or nvram erase via telnet/ssh (Do not 30/30/30 an ARM router!)
  10. Once the router has rebooted completely after resetting, in your browser, go to http://192.168.1.1 where you should be greeted by the DD-WRT password change page in the WebUI.
  11. Set username and/or password and click Change Password.
  12. Configure router to your needs.

TP-Link Archer C9 v3, v4

Device thread: TP-Link Archer C9 v3? (EU)

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 original (deprecated) fix is here.
  • Easier-to-read v4 de-brick thread is here

NOTE: There is a US-only version of the v4 that is not yet supported - Archer C9 V4 Unable to install firmware


TP-Link Archer C9 v5

NOTE: This version is NOT currently supported. Doesn't look as if it will be anytime soon, either:

Troubleshooting

Device Forum Thread: https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=282831

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!

Recovery Mode

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