I’ve got a RouterBoard 750 and since yesterday it seems to be frozen - I can’t even ping it.
All port lights stay on
Power light at the back stays on
ACT light does not come on
This is the situation from the moment that I turn on the routerboard - absolutely nothing changes - not one single light blinks (ever).
I have reset the router by pressing (and holding) the reset button at the back - until my finger becomes numb - while cycling the power state. I have reset the router by short circuiting the pin hole under one of the rubber feet. Each time nothing happens - not a single light blinks.
I also tested all 3 capacitors on the board and found all working fine. I think it might also be worth mentioning that I did not upgrade the firmware recently.
Any help on this subject would be greately appreciated - as this is quite urgent.
Use Netinstall and a serial cable. Connect to it via a terminal program.
There is help on this in the Wiki pages.
If you connect the serial port with a cable it should show up with text, and then a login prompt. If nothing appears, check the cable, and if good, then probably a faulty board.
