    If you measured the current directly across the power supply then you were:

    a) doing it wrong
    b) risking damage to both your meter and the power supply.

    Try finding another 12V 1A adapter and see if the router works with that.

    You can continue to use the 12V 0.5A PSU and your router will probably work just fine. If you really want to repair the original PSU, I suggest you start by measuring the blue 1000µF capacitor which corresponds to the burn marks on the other side of the PCB and R18. Does your multimeter measure capacitance?

    "don't fix it, it ain't worth the time or money" .
