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.

the service center has confirmed that the usb board is bad.  From what i can gather, the part isn't readily available... its ordered, but no timeframe.  Teac/Onkyo are of no help whatsoever.
You will need to elevate your complaint at Teac to a supervisor.  Tell them what is going on and that the “regional service center” told you to call them.  Let them also know that this issue is being reported a lot on the Audiogon website and that it is obvious there is a quality control issue.  Remind them that a 2,000 dollar piece of equipment should not break this quickly and you know from another source that the part is available, IF THEY REALLY WANT TO HELP YOU.  
I did this and ended up getting the part next day aired to the service center.  I was originally told it would take 2-3 weeks.  The part is there, IMHO.  I just believe they are having issues and trying to manage where the parts are going to.  Kind of like toilet paper :)
I live in Canada and I also have the same problem as Silivio 66, no LAN connection at all. Replaced RJ45 cables many times, diectly connected to the router using a 3' cable, CAT5E/CAT6/CAT7 are all tried with no luck. So annoying and this unit only has less than two months running. TEAC NT505 sucks!!!
Call Teac.  Get in touch with someone about a repair for you.  Then ask to speak to their supervisor.  Tell them your problem and that there are numerous threads online about this issue.  THEY ARE AWARE OF THIS. Don’t back down and let them know you expect them to stand behind a 2,000 dollar item that is only a few months old.  If you’re lucky, you will get a replacement unit.  At the least they will suggest a service center for repair.  I don’t k own what is available in Canada, but in the states, Adams Electronics in California has experience with this repair.
i wish you luck.
My unit was repaired and is now flawless.
Finally I got my Teac NT-505 connected online again, what a tough jouney to get this working again. Ok cut the story short please see the following course of events:

1. On August 3rd, 2020, my home network was changed from Bell DSL to Cogeco Cable due to speed upgrade, from 50Mbps to 1Gbps.
2. Teac NT505 stopped working.
3. Copied and pasted the exact modem/router settings on Bell 3000 modem to Cogeco Arris modem. Teac NT505 was working for less than 30 minutes then lost ethernet connection, check light kept blinking.
4. Replaced RJ45 cable three times with CAT5e/6/7 still not fixed.
5. Ran new RJ45 cable 6' directly from the Arris modem/router, byapssing the D Link switch, check light contiued flashing. Not fixed
6. Left it for couple days to relax and calm myself down, cup of coffee and a nice piece of dark chocolate from Swiss would help to think.
7. Bought a Asus WIFI mesh system, two pack combo, ZenWIFI XT8, I was planning to improve my house's WIFI anyway...
8. Got it setup and connected the Teac NT-505 to it directly and guess what!!!, working right away with no issues, I had the unit on for more than two days with no cutout of signal. Teac NT-505 has no WIFI capability only wired. Arris modem to Asus router(wired) then through WIFI to Asus AI mesh node then from AI mesh node to Teac NT-505 wired. By the way I added two more Asus AI mesh nodes to the network for other devices in the house. Asus AI mesh system ZenWiFi XT8 is the top of the line and it is not cheap, around CAN$600 plus tax for pack of two. I have 4 of these routers in my house. Read Asus website for details.

Conclusion:
Teac NT-505 is very picky about router type and definitely hub or switch is not remmended.
I hope this will help!!!
New version V1.22 has no issues and this unit is running great.
