In general, I would use these steps:
Edit this file:
/usr/share/dbus-1/system-services/fi.epitest.hostap.WPASupplicant.service
by adding " -ddd" after /usr/sbin/wpa_supplicant so it looks something
like this:
Exec=/usr/sbin/wpa_supplicant -ddd -c /etc/wpa_supplicant/wpa_supplicant.conf -u -f /var/log/wpa_supplicant.log
Then reboot. This will add lots of debugging information to the log
file (which may grow fairly large).
Then when you have a problem connecting to a wireless network, open a
bug against NetworkManager and attach these files to the bug:
/var/log/messages
/var/log/wpa_supplicant.log
NOTE: /var/log/wpa_supplicant.log might be zero bytes in length. If
that happens, find the latest logrotated copy of the file and attach
that one instead:
ls -ltr /var/log/wpa_supplicant*
e.g. /var/log/wpa_supplicant.log-20080722
Also, paste the output of these into the bug:
nm-tool
dmesg
(the latter can be helpful to see kernel messages from your wireless
driver)
Also, note what you see in the nm-applet drop-down list, whether there
is a security icon or a computer icon, etc.
