I understood that I did not explain correctly my issue: my problem is not the FIRMWARE upgrading via usb rear port (already done several times)
My NT-505 DOES NOT establish any connection to LAN via Ether port (no protocol session starts hence no IP@ is assigned to NT-505 port by the router)
In this condition the device results unreachable by anythings running over IP protocol (apps included). This means that I'm looking for an alternative method in order to upload the NETWORK fw.
Summarizing:
SYSTEM FirmwareV1.22 -> done (from japan site) and running correctly
NETWORK FirmwareVer11.6c -> not possible because It seems that via app is the only manner to do this.
I have two hypothesis: shipped without network fw on board or such chip managing the Ether port does not work.
