I'm bulding a project with Pi Musicbox on 3B+.
Everything worked fine for 3 months until last night, when it mysteriously stopped getting an IPv4 address from my router.
Sometimes it still connects, but the router does not even display it in the list of clients, but I'm able to connect via ssh using hostname (musicbox.local).
How do I troubleshoot it?
I have an arduino on usb, and a button and a rotary encoder over GPIO.
