I used another supply from a Wet54G, same story and vice versa.
I connected a professional power supply with V/A display and from 4-5.5V the
powerled is on and the ACT led is just flashing in a high rithm with short
pulses.
When the voltage is above 5,5V then the ACT led becomes green and the
current is raising to ca. 500mA.
I meassured the voltage on the circuit and there is no drop between the
power supply and the Wap11.

There is something wrong because it hás to work on 5V but most important is
that it works again and, it seems, better dan ever.
