Death Wl500gP v1
I found here same problem. i have had death power supply (giving just 3V instead of 5V). So I substitute by other power supply with 5V(10Amps). But after power on lit power led and one LAN (there is my pc) after aprox 5sec goes lit LAN 1~4 and WAN, power led turn off. I tried wl500g-clear-nvram.trx and wl500g-restoration.trx after those steps I can see unit running in some safe mode. I can connect through putty I can see running services, can ping to 192.168.1.1. When I tried any other FW, I'm getting same issue like before for few seconds it seems ok but after lit on LAN1~4 and WAN. Any pin trick?
Thanx for your response
