Yesterday I brought up a brand new Pi Zero 2 W and after a bit, it was all hunky dory.
Sometime last might, it went offline. No route to host.
I rebooted it and it lasted half an hour. Then it wouldn't reboot at all. Its now sitting next to the wifi router is configured for and is for now accessible.
I have no HDMI adapter for it., Its headless and normally accessible via ssh.

 Reading logs is one thing, but immediately being able to test a hypothesis is much better.

Prolly easier to get an HDMI and USB adapter and pop a monitor and keyboard on it.
I spent hours yesterday googling for PI ZERO 2 W WIFI DISCONNECTS and everybody has the same problem. Must be 1000 posts out there. It seems that the 2W is basically a piece of shit. People try SD cards that work perfectly in the Zero W, but don't work in the 2W.
I tried every methodology suggested, and its still doing it.
I am tempted to buy the old version, two  of which have been faultlessly connected to the same wifi point for several years....
Unfortunately I soldered a header block to this one so I can't return it. Bin job probably.
