Model: Archer C6  
Hardware Version: V3
Firmware Version:

I'm using an Archer C6 V3.2 (US) router, but none of the LAN ports are working. I've already connected the router in UART-USB mode. Recovery via the web interface isn’t an option since the LAN ports are non-functional.

How can I flash the firmware directly using serial mode without relying on the LAN ports?

 Hi @GlichPoP,

I understand your desire to restore the device to normal operation, but currently we recommend only two ways to update the firmware: online update and manual update. If you use other unconventional methods to update the firmware, it will also cause damage to the product, which is not covered by the warranty service. You can consider buying a new router.It is recommended that you use the regular LAN port to update the firmware.

If all Ethernet ports are unresponsive, it may be hardware failure. You can consult local support for warranty consultation.
