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.

Sorry that you guys/gals are having trouble. Before this issue I’d never heard of any NT-505 trouble, but I guess it’s probably not that widely owned. Hope Teac gets it fixed or replaces the defective units.

Since I’ve not had any trouble in a year running version 1.21 firmware, I’m sticking with that and not flashing to the 1.22 version. Indeed, I have a lot more trouble with my Bluesound unit than I ever have with my Teac, which has been (knock on wood) flawless for me -

I had the 1.01 firmware, or whatever it was that it came with and other than some initial issues when I first got it, no problems until I upgraded the firmware.  I still think my issue might be network related though, so I'm withholding judgment for now.

Maybe try version 1.21 firmware if you haven’t already?? Which if I recall was from December 2018.
I did notice an improvement going from the shipped firmware version to 1.21. Mainly more stable in terms of dropouts during play is what I found after the switch which I did a week after getting unit if I recall

My unit came with v1.21, but I guess I was too quick to upgrade before I actually did any extensive testing. Not sure if I can downgrade now, especially the network piece which is 11.6.c now after all upgrades. Teac support mentioned v1.22 should bring more stability then anything else in terms of network connectivity, but who knows. I may look into downgrading if at all possible before I do the exchange with a new unit.

Do a factory reset (easy to do), then download the 1.21 firmware and install it.
