[SOLVED] wpa_supplicant CTRL-EVENT-DISCONNECTED bssid=xx:xx:xx:xx:xx:xx reason=4 locally_generated=1

Hi everyone,
Ubuntu 22.04

System was running for long months just fine and today all of the sudden WiFi gets disconnected after some minutes since boot and there is absolutely no way to reconnect.
System does not see any wireless networks at all.
The only thing that helps (for a few minutes) is reboot.

By looking at syslog i can see:

Code:

wpa_supplicant[714]: wlp2s0: CTRL-EVENT-DISCONNECTED bssid=xx:xx:xx:xx:xx:xx reason=4 locally_generated=1

reason=4 means: "Disassociated due to inactivity"
I know that from here: https://www.toomanyatoms.com/compute...ion_codes.html

What i already tried, and didnt help was to set wifi.powersave to 2 (disable powersave) in /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
Previously it was 3 (enable powersave).

Any other ideas what might be wrong here?

Based on your syslog, your client lost AP and then start to scan the AP. But AP is gone, can't be found.

Are other wifi devices also having this problem? Just wondering if your AP is acting up.
Instead of a reboot have you tried restarting wpa supplicant?

Code:

sudo service wpa_supplicant restart

Hi guys, thanks for your replies.
I dont really know what was root cause of this issue. The fact is that all of the sudden all wireless networks were gone only for that specific host.
I tired number of things including restarting wpa_supplicant (ty @uteck) but none helped.

Eventually, I have reinstalled network-manager and that did a trick!

Code:

sudo apt reinstall network-manager
