I found a WRT54G v1.1 (20 LEDs, mini PCI) at the swapmeet. It didn't come with a power adapter. I looked at the linksys page on it and it seemed to use a 12v center + adapter. I found a suitable adapter and plugged it in. Couple of lights blinked on the front, then there was a pop, then I could smell burning. Great, just great. A physical examination of the board does not show any visible damage. I read some references to a protection diode. I have been looking around the board for that. I found a couple of square surface mount diodes but they don't appear failed. Can anyone direct me? I tried the linksysinfo.org forum search but that is broken, none of the returned links are valid, so I can't search the forums here for this. Someone should fix that.
