I have a cudy n700, it does not seem to reset or enter recovery mode, this is the second one with the same issue can you assist with resolving this urgently
@Dear Otis,
I think there is something wrong with the router. The router can’t be recovered.
“Hello , i have a CudyWR3000 and i wish to put it in recovery mode so that i can tftp my way into openwrt , the issue is , i can not put in recovery mode , i have tried holding the reset button while its unplugged and then plug it back in and keep holding for 12 seconds , at times even longer and no matter what i do , i do not get a rapidly blinking light indicating recovery mode , all i get is a steady power led and the internet led slowly blinking ( mind you when its in that mode which is not recovery no other light is on , just those two) . I thought that perhaps its recovery mode and i am missing something , i went on with the process the same way i would with it being in recovery , no matter how many times i tried or changes i made tcpdump indicated no request coming from the router .”
@Estimado Javier:
De acuerdo. Creo que está relacionado con el canal de trabajo. Algunos canales no admiten 160 MHz.
“He tenido que volver a las versión del Firmware original, ya que en Openwrt al configurar la Wifi 5G en ancho de banda 160 mhz, desparece y no se puede conectar. He hecho muchas pruebas y es cambiarlo a 80 mhz y si funciona. Este problema con el firm de Cudy no pasa. Se queda configurado en 160mhz y todo normal.”
