ProtoDAC TDA1387 X8 project

Couple things:

1. Linux manages all network connections way before moOde even starts. All moOde does during its startup sequence is check for an IP address assignment.

2. WiFi suddenly dying or becoming unreliable can be a symptom of interference. The infamous HifiBerry issue from back in the day where one of its clocks generated RFI that interfered in the 2.4G WiFi band is an example.

To troubleshoot you need to start from a clean slate.
Use your full board stack.

1. Start with a fresh moOde 8.3.8 image
2. Connect using Ethernet
3. Set "Output device" to "I2S audio device"
4. Set "Named I2S device" to "ProtoDAC TDA1387 X8"
5. Reboot
6. Verify that everything works

Troubleshoot WiFi

1. Leave Ethernet connected
2. Open Network Config and define your SSID and password (use SSID for 5GHz band first)
3. Reboot

Post the contents of the startup log and output from the commands below

1. Startup log
The log can be viewed via the SSH command moodeutl -l or downloaded via the Logs section in System Config, or via Menu, System info from the any of the Config screens. The startup log will be at the end of System info output.

2. WiFi info

Code:

ifconfig

iwconfig

Hi @Tim Curtis trying to understand your guidance here better. So you are asking me to recreate the 'failure' mode with ethernet cable connected, correct? In other words, do this test from the location (my office room) where Wifi is dying but with ethernet cable connected so that you can see what is happening in start up log for the Wifi config? I just need to find a 20 feet ethernet cable ? 

FWIW yesterday I tried to start from clean slate multiple times. I typically set the Wifi SSID and password while imaging the SD card using RPi imager tool. And yes I've been entering the 5GHz band info. I was able to see the 5GHz connection in the router when it connected successfully from my living room.

Finally, is the start up log stored in the SD card boot partition somewhere (hidden)? I can plug in the SD card and try to get the startup log if that is feasible.
