TEAC NT-505 impossible connecting to WiFi router o such LAN: help me please?

Hello mates,
I got my NT-505 3 days ago.
It seems to be working correctly but in my opinion all software in not the same level than the device: too aged & often no relevant documentation or support about.
However my big trouble is the NETWORK interface:  since first time I switched on, the NT-505 remains "for ever"  into NET configuring blinking state until it goes in power stand by.
Summarizing:

1. RJ45 cable is ok - tested in several manners
2. the wifi router (1Gb fiber connection) is ok
3. the wifi router ether ports (4) are ok - I checked a bridged LAN configuration too

Testing the NT-505 Ether port It results:

1. the physical level of protocol seems working correctly just on-way: the interface recognizes correctly the bandwidth (Fast ot Giga in my case) end the packet coming from the router are buffered. No packet sent  to the router.

2. At protocol level no ARP session are involved hence impossible retrieve MAC address and trying to do something.


VERY STUPID ISSUES:

1. Being NET board logically split from MAIN board It's need a separate firmware(!!!): how can I upload the NET firmware if, as stated into documentation, I must use the mobile app and It's impossible connecting the device to such LAN?

2. NO menu interface to configure manually the net parameters.

May someone help me (tricks..., recovery sw,..., low level maintance menu...,...) 

Thank you a lot.

Correct, what audiojedi said. It says it is doing an initial update when you initially get going but that is just the phone app.

To do the firmware upgrade to the NT-505 itself you need to use a PC (not mac) and use a physical cable to connect to the little micro USB port on the back at bottom just above the word "Digital" (which is confusing because the "Digital In" label refers to the optical input, not the micro USB, which isn’t labeled).

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.

Might check if your  router is set to hand out IP addresses by DHCP. Looks like the Teac is trying to get an address and is timing out. Other than that you could try Teac support it could be a bad chip.

Yes my router is DHCP on. Trying with external DHCP server the behaviour is the same. The devices does not react to ARP req send by router hence MAC@ end IP@ cannot paired in ARP table. Just to understand: normally after rj45 cable is plugged then NET is set like source should the NT-505 work simply?

What cat level Ethernet cable are you using? (Eg, cat 7?). Assuming you’ve already tried a couple different Ethernet cables right?
