It fails running the first command:

mint ~ # dbus-send --system --print-reply --dest=fi.w1.wpa_supplicant1 
/fi/w1/wpa_supplicant1 
org.freedesktop.DBus.Properties.Setstring:fi.w1.wpa_supplicant1

process 4403: arguments to dbus_message_new_method_call() were 
incorrect, assertion "iface == NULL || _dbus_check_is_valid_interface 
(iface)" failed in file ../../dbus/dbus-message.c line 1346.
This is normally a bug in some application using the D-Bus library.

Couldn't allocate D-Bus message

Edit : Thanks much for the help, but more reading on the Net shows that 
the ath9k driver was built by Atheros and appears to be buggy.

I found an old USB wifi connector (TrendNet TEW-444UB using Atheros 
AR5523), which worked right away.

I'll just disable the on-board wifi chip and use an external USB chip 
instead.

Thank you very much.
