Public bug reported:
= Expected =
Wireless Network to reconnect fine after suspend.
= Actual behaviour =
Network manager is claiming password is not valid for wireless network,
wpa_suppliant in debug mode compaints about various errors, like WPA MIC and
ioctl errors, causing not to be able to connect.
= Debug output to for workaround =
- I have stopped the network manager;
/etc/init.d/network-manager stop
- I have killed any remaining wpa_suppliant instances;
killall -KILL wpa_suppliant
- I have started the wpa_suppliant in debug mode;
sudo /sbin/wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_supplicant.conf -dd -t
2>&1 | tee -i /tmp/wpa_supplicant.log
- I have included my Terminal output in the logfile was well;
export PROMPT_COMMAND='history -a; history -r; logger -t Terminal
"`tail -1 $HOME/.bash_history`"
- I have poked-it-with-a-stick to get it working again using various
instances of rmmod modprobe, ifconfig, iwconfig, tcpdump but this method
is not reliable and cannot be reproduced every time.
= Most interesting messages to me =
When looking at the logfile there are a few messages which worries me the most,
but I cannot deduct any logical or workaround based upon them:
- WPA: Could not verify EAPOL-Key MIC - dropping packet
- ioctl[SIOCGIWSCAN]: Invalid argument
- ioctl[SIOCSIWAP]: Device or resource busy
