This is 12.3 with Xfce and Network Manager, connecting through wifi.
Once in a while, sometimes twice a day, network just disconnects, the bars in the NM icon turn all grey and there's not way to reconnect but a restart, which always works.
Changing the settings, restarting networking either via NM or systemctl, resarting with a physical wifi toggle button on the laptop, logging out - nothing helps. IP4 addresses are set manually.
Here's some terminal output:
What gives? Why nothing but a restart fixes it? One time I got the network back after troubleshooting with ifconfig and other terminal commands but I can't replicate this solution anymore.
After toggling wifi on/off NM tries to connect, gives up, and shows "no network" icon. At this point iwconfig and ifconfig look like this
Gateway settings and IP address are gone but SSID and access point are still visible.
