Running raspbian (still on armv7) headlessly to serve up a few container services. It’s worked for a few months now no issue. In the last couple days, I updated all the docker images and raspbian. Now I’m having an issue were it drops connection (wifi and ethernet) all together.
My first quick attempt at a fix was to swap out the 4 with an old 3b, this did not work. The 3b was up ~16hrs before dropping connection. So prob not a hardware issue?
