I do have two damaged RV042 units. One does blink with the DIAG led constantly, the other does not. I did replace the elecrolytic capacitors, so the problem must be comming from somewhere else. - both devices do respond to ping on LAN side to 192.168.1.1. - It is possible to connect through HTTP. But, device just wants to download a firmware through here. In any case the procedure does nothing. After uploading firmware, device resets, and there is no apparent change in how it works. - It is possible to telnet to the device boot loader. Is it possible to test the device somehow? For example: Why, the system does not boot, or Is the flash working correctly?
