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.

I've been following this thread and one of the things I realized was that I hadn't updated the firmware on the device.  I did that yesterday, and now I can't connect to it, with the Lumin app or BubbleUPnP.  Strangely, I can cast from Spotify to it with no problem.  I'm about to do a factory reset.  

To badger... I upgraded from a Bluesound Node 2/Auralic Vega DAC to the NT-505 and it was a noticeable jump in sound quality, imaging, and soundstage.  Yes, it does MQA.  I really like it, other than my current frustration, which could be an issue with my network.  I've been having some other issues and am not sure if it's the TEAC or the network at this point.  I've ordered a new router and will see if that clears up all the issues I've been having.

badger,
Yes, I find it to be a fantastic unit for its $2k price. Full MQA, yes. I run mine with balanced XLR’s to Audio Research integrated amp.

Dual monaural AK4497 dacs, dual torriodal power supplies, fully balanced, two on-board clocks (with provision to receive an external 10MHz clock if you want additional performance), DSD 512, outstanding analog output section, several filter and upsample selection options (or option for none), Lumin software, Roon ready, .... Incredible value. I’d love to hear it compared to a Lumin T2 at $4.5k msrp - wish I had access to one to do a shootout.

Other than the occasional dropout issue I was having first month, which was 100% solved by going to Cat 7 Ethernet cable, my unit has been entirely trouble free for me, and it gets heavy use.

You might try flashing the 505 with a previous firmware silvio66.

Dear djones, here in Italy COVID-19 is dramatic situation:everybody must remain at home (I since 30 days).
I have a lot of time in order to play into my HiEnd room: I had tried everything :-) remain only to open my NT-505 then...
I'm joking...take this opportunity to thank all of you for supporting and stimulating my English
