  • 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
  • Do a normal reset or nvram erase via telnet/ssh (Do not 30/30/30 an ARM router!)
  • 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: Working Solution to Archer C9 V1 - software only, no serial

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.
