The system does not appear to be fully updated:
stable 6.5.12-1 is current as of today. 6.5.13 already has been marked EOL.
Have you tried a LTS kernel, either 6.1 or 6.6?
Have you looked into wifi powersave options e.g. in tlp.conf?
# Wi-Fi power saving mode: on=enable, off=disable.
# Default: off (AC), on (BAT)
WIFI_PWR_ON_AC=off
#WIFI_PWR_ON_BAT=on
Or disable network manager powersave:
Disable Wifi power saving:
You can disable Network Manager's power saving features by creating /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf with the following command::
sudo touch /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
Add the following contents to the newly created conf file with your preferred text editor:
[connection]
wifi.powersave = 0
Reboot or restart Network Manager
