I have a routerboard 751U 2HnD that has been out of the box for less than 24 hours. All of the LEDs are flashing on and off in unison, including the PWR and ACT lights.
I was using it when the SSID disappeared, and now I can't get any response from it at all by wireless or by LAN. the power supply voltage is 12.08V. the power supply is fed from a 1kw pure sine wave inverter with the only other load being an ethernet switch which is functioning correctly.
what does this mean when the lights all flash on and off together?
