[SOLVED] RPi3A+ Network instability.

[zandman]

I did have similar issues with my Pi3A+, but only on 9.0.1. You are not alone :-)
It starts up fine from a fresh SD image, but after changing some essential settings the interface freezes. I believe it happens after I add my NAS tot the library
No issues on 8.3.9

Today my Pi didn't even startup anymore, it doesn't read the SD card. So maybe my issues were (partially) due to a failing SD slot.

New Pi5 is on the way

What NAS are you using @zandman?

Sorry for the late response. My NAS is a QNAP TS 464. No issues with the Pi5. My 3A+ officially died, so can't test anymore
