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!
