Same problem here with WL-500GP v2 . LAN1-4 and WAN go solid when i plug the PSU while AIR and POWER stay off. I tried (in this order) :
- Power the router with PC PSU (a new one) - same
- Pin 9 to GND - same
- Pin 12 to GND - same
- Pin 16 to GND - same.
- Also tried with 2 more 5V/3A adapters - stays the same
Now , I read about a guy who shorted VCC and GND in combination with pin 12 and pin 16 to GND , but this VCC to GND sounds risky. Should I try this
I opened my PSU to check the capacitors -they look normal (no swelling or leakage). Also capacitors inside the router look good/same.
I double and triple checked the voltages - all adapters had 5.18V to 5.23V. As far as I know by looking at some test (maybe here, I don't remember) that the router draws about 1A while booting , so amperage should be sufficient even with a less powerful PSU.
My flash chip is MX29LV640DBTC-90G. Can somebody help with the right pins to shorten on this chip ?
I spent my whole Sunday searching for a solution and nothing .
Hope you can help us guys .
Thanks !
