Hello, 2015-01-23 8:59 GMT+01:00 Alexander Aring <alex.aring@xxxxxxxxx>: >> Do you are sure that there is no daemon running or something else which >> automatically ifup the interface again if you want to set it down?

After your pointers I've found the answer on one of the forums - the problem is caused by ifplugd service, which automatically brings up wpan0 interface after it is brought down. It seems that in previous branch (linux-wpan-next) this problem didn't exist, because wpan0 interface had to be manually created (and ifplugd didn't mess with it). Solution 1 (blunt): killall ifplugd Solution 2: edit /etc/default/ifplugd My working /etc/default/ifplugd below: ____ # This file may be changed either manually or by running dpkg-reconfigure. # # N.B.: dpkg-reconfigure deletes everything from this file except for # the assignments to variables INTERFACES, HOTPLUG_INTERFACES, ARGS and # SUSPEND_ACTION. When run it uses the current values of those variables # as their default values, thus preserving the administrator's changes. # # This file is sourced by both the init script /etc/init.d/ifplugd and # the udev script /lib/udev/ifplugd.agent to give default values. # The init script starts ifplugd for all interfaces listed in # INTERFACES, and the udev script starts ifplugd for all interfaces # listed in HOTPLUG_INTERFACES. The special value all starts one # ifplugd for all interfaces being present. INTERFACES="eth0" HOTPLUG_INTERFACES="eth0" ARGS="-q -f -u0 -d10 -w -I" SUSPEND_ACTION="stop" Thank you very much for your help!!!
