WAP11 broken?

My Wap11 with Dlink DWL-900AP+ firmware doesn't respond anymore.
The ACT led is flashing unregular and reset doesn't work.
I connected it with a cable but the PC sees no connected device (network
icon with red cross).

Trashcan?

I connected another powersupply (6V instead of 5V) and is working again!
With 5V it consumes 270mA en with 6V 450mA.
It seems the build in power regulator has a increased voltage drop.

Just for the records:

I contacted Linksys.
There is no voltage regulator inside, but 6V is no problem they said.
The eeprom might be getting worse and with a little extra voltage it's
workin fine for the time being.
And it's still workin, the IC's are not getting hot.

It seems I also increased the send power with this power tweak because I
never before had such a range.

The wall wart on a WAP11 ver 2.2, in my pile of junk, shows 5V 2.0A.

Your 5V at 0.27A = 1.4 watts. That is far too low for a typical
WAP11. I'll measure the current drain later today but my guess(tm) is
about 5-7 watts consumption. Something is wrong. Are you sure your
5V wall wart is putting out about 5VDC? The 5V switchers are not
known for their reliability. However, when they fail, they usually go
to zero volts output, so that's probably not the problem.

At 5.0VDC, my WAP11 v2.2 draws 0.75A. Interestingly, when I first
apply power, the current drain is about 0.55A. After about 6, it
turns on the radio and draws 0.75A.

The unit will function down to 4.3VDC without any degredation. That's
because Linksys is wrong as usual. There is a 3.3VDC internal
regulator for the CPU and wireless. I also tried it at 6.0VDC which
also works. Current drain at 4.3 thru 6.0VDC was a fairly constant
0.75A which implies a fairly crude analog voltage regulator and not a
switcher.

If your WAP11 happens to be a v2.2, and is only drawing 0.27A, then
methinks there's something wrong with the wall wart. If you 6V
replacement only draws 450ma, I don't think you're giving it enough
time for the wireless to turn on. However, the multitude of different
hardware versions might have different power drains, especially if you
also did the adjustable power hack in the firmware.

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.
