Here is how I get rid of this inconsistency :
in interfaces file I put those stanzas : iface wlan0 inet manual wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf iface default inet dhcp wpa-roam slave iface home inet static wpa-roam slave address ... With attached patch, "wpa_action wlan0 stop" is invoked when issuing "ifdown wlan0" ** Attachment added: "kill wpa_supplicant when shutting down roaming interface" http://librarian.launchpad.net/5171706/wpasupplicant-ifupdown.patch -- ifupdown script fails to terminate wpasupplicant https://launchpad.net/bugs/72152 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
