Loss Wifi connection after few hours

[Leberkasbepi]

Hi there, I updated my Pi a few weeks ago with the update command for the OS. Since this, the Pi loose always the wifi connection after a few hours and don't reconnect. So I have to shut it off.
Today I have to formate the sd card, so I have a clean install, but the problem is the same. He runs a few hours and then no wifi. I don't change any settings on my router. OS is the raspberry 64bit lite (no desktop).
I tried to turn off the power save for wifi, but don't help.
I have a second raspberry and have no problem with this.
It seems to be a problem with the update from raspberry.

Is there a change to get back of older versions of the OS with older updates?

I made an image from the sd card from the workin PI and write it to the sd card from the PI with the issues. Since that it works fine. So the issue have something to do with a OS update and don't recommend it!

Another example of "never change a running system".

Ok, it don't fix it -.-

I'm having this issue on my Pi Zero 2 W build as well.

In my case, the problem seems to be that some updates on the inky (like RSS) take several minutes and puts the CPU under heavy load.

If NetworkManager tries to refresh the WiFi at the same time, this seems to timeout and/or fail - and it marks the connection as deactivated and it won't try to reconnect.

I setup a script to reset the interface if the networking dropped but didn't fully solve it. I've just updated it to instead restart NetworkManager and also explicitly force the connection up (marking it active I think) - hopefully that solves it but we'll see...
