https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D256494 --- Comment #8 from vermaden@interia.pl --- I also found an interesting 'side effect'. After my main home WiFi ssid disappeared (power outage) I was not able to connect to my temporary WiFi hotspot served from phone. I even commented out (with '#' chars) my home WiFi ssid from /etc/wpa_supplicant.conf and *ifconfig wlan0* still showed ssid as my home = WiFi network. Resetting that with these did not helped: # ifconfig wlan0 ssid - # ifconfig wlan0 ssid phone-net Other interesting thing - after doing *destroy* on that wlan0 interface it reappeared itself after bring destroyed with ssid to my home WiFi network (= the on that disappeared during power outage). # ifconfig wlan0 destroy # ifconfig wlan0 destroy ifconfig: interface wlan1 does not exist # ifconfig wlan0 destroy # ifconfig wlan0 destroy Each command executed successfully because wlan0 recreated itself. If I typ= ed them too fast then they yield that wlan0 does not exists and the next execu= tion was successful because wlan0 again existed without me creating it. I have 3 additional /var/crash dumps but I will upload them later when not = on a WWAN connection. When that laptop rebooted with crash dump the WiFi card was still fucked up each time. The only thing that allowed me to connect to different WiFi netw= ork after my main WiFi network disappeared was to push power button for 5 secon= ds to power down that laptop 'hard' and start fresh boot. Hope that helps. This is 13.0-RELEASE without any patches as the ones that showed were not vulnerable to me. Regards. --=20 You are receiving this mail because: You are the assignee for the bug.=
