WAG302 Core Dumps?


WAG302 Core Dumps?

My WAG302 v1 (firmware v2.0.11) randomly dumps a core. There doesn't appear to be any rhyme or reason to it:

I just took my WAG302 out of storage and - after resetting the unit to the factory defaults - connected to the serial console interface and saw this when I turned the unit on:

Can this unit be saved or is it junk? :confused:

Nobody, eh?

I suppose that it's time to get out the tools and go to work. :rolleyes:

Re: WAG302 Core Dumps?

Ive just encountered your problem (hence how I found myself here) and I believe I can give you a fairly reliable solution. I thought I might post it to save anyone else the wasted time (weeks for me, years for others).

The problem is plugged into the back of the AP, its the power supply. Unfortunately the original power supplies *will* fall outside of their specified ranges but not enough to actually stop the unit from working outrightly.

I picked up a 12v REGULATED (if its not regulated, your only prolonging the problem) power supply, that was intended to be a replacement charger for a laptop, few cuts and joins and its back to better operation than I EVER got out of it orignally ....

If your not sure this is your problem, just take a look at the LED's on the front of the unit, mine were on and functioning no problem, but they were a little dull, now they have their proper reasonable LED intensity.

Hope this helps someone else out there 🙂
