Hello,

I bought a used TP-Link Archer C7 router. When I got it home and plugged it in, I get no LEDs lighting up whatsoever.

I disassembled it and tested voltage at the plug/socket, which reads 12v. So, I know I'm getting power to the board.

I did try hooking up a USB to UART/Serial cable to the pins on the board based on guides seen on this forum, but I am not seeing any output from it when booting the device.

A quick inspection of the board shows no damage. I do notice that when I plug the power cable in and turn the router on, the USB LEDs on the back light up for a fraction of a second but then shut off.

I'm assuming this board may be shorted out or have a bad capacitor, but didn't know if anyone else had any other suggestions on what to test/look for?

Thanks!

Thanks. Can you give any more details as to what would be involved in reflashing spi?
