wpa_supplicant writes to /var/log/syslog. You can run it with option -d or -dd to add verbosity, but it is started automatically by network-manager/dbus so you don't get to enter your own options. How do you increase verbosity anyway?

For older versions of network-manager (<0.9), you can edit


In 0.9, the file has changed to fi.w1.wpa_supplicant1.service, so you now have to edit


The file should look like this:

[D-BUS Service]
Exec=/sbin/wpa_supplicant -u -s -O /var/run/wpa_supplicant

And you can add your options in the Exec line. To make network-manager restart wpa_supplicant, run

ps aux | grep wpa

and kill the wpa_supplicant process

kill -9 12345

It will start back up automatically.
