H E L P !! Network issues with Teac NT 505?


I have a Teac NT-505. It sounds very good when I can get it to work. The problem as I see it is too many handshakes have to be made by too many pieces over the network. Both hardware & software are involved. FWIW I'm trying to get the music from a HD on my  my computer in the office to the Teac in the LR

My library resides on a Hard drive of a computer which is in my office. I run Serviio as the server. I use BubbleUpNP on my tablet to control the system. I have a Linksys WRT 1900 acs router which is/was among their best. Though I have used computers for 30 yrs and stereos since I was a kid, I am not the best at troubleshooting network issues which is where I believe the problems take place due to too many handshakes necessary  between too much hardware and software. I am hoping to resolve the issue by direct connection of a HD of some description which will take the library off of the network. But I haven't tried that yet, mostly because I'm old and tired of dealing with issue after issue. Then too, even after I do that , IMO, there is no guarantee that will work and I am tired of experimenting with it. I bought the streamer/player/Dac  with the thought that it would be easier. But its been very exasperating instead.

MY other choice is to try another streamer, IE an Aurender which has the proprietary  HD and software. But then I will need a Dac which adds more expense which strains the budget of an old retired guy. I could use the Dac of the Teac but was hoping to sell it to help fund the Aurender, etc
Am I on the right track?

I am currently struggling how to get my Teac nt505 to connect to the network. All other functions are working fine except the network. The network connection was working before but somehow it stopped working two weeks ago. 
troubleshooting steps:

1. Power down to reset no good

2. replaced lan cables with different cat. 6/7/8 no good, this unit was using cat7 with no issue before

3. replaced mesh router no good but the mesh node is fine with other devices

4. Firmware is v1.3

5. I am using an ipad to control the app functions with no issue before. It looks like the unit is not on the network 

please help if possible 

I can’t update the network firmware simply because Teac hr streamer app requires the Teac unit on the network 

Could be the broken I/O board issue (if i recall - don’t quote me) discussed in the other NT505 thread. I actually thought yesterday I might be dealing with same thing.

Using wifi extender in second system far away from router, and then cat 7 from extender to NT505. Had worked mostly flawlessly for couple years but lately wasn’t connecting as well.

Used as opportunity to finally upgrade firmware (done via micro USB cable from PC directly - network not needed) to go from firmware version 1.21 to 1.30, current as of November 2021.

Then took the unit downstairs and directly connected to the router via same cat 7, and it worked, so I knew it must be my wifi extender.

Anyway, I had another extender, paired/linked that to the router, and now working again upstairs. But it feels a bit tenuous....... Always takes a bit to lock on and I’m never quite sure - have taken to leaving it on and hopefully connected all the time, see how it goes.

BTW I use the Lumin network app, not the Teac network app - as for me it is preferable. But all that said, I’ve gotten 3 years of great use out of the dac and still like it very much
