network configuration at start up is failing

Hallo everyone,

My BBB seems NOT to be able to assign network properties at startup.

Linux version 4.4.23-ti-r51 (root@a2-imx6q-wandboard-2gb) (gcc version 4.9.2 (Debian 4.9.2-10) ) #1 SMP Mon Oct 3 22:56:05 UTC 2016
IMG: BBB-eMMC-flasher-debian-8.6-console-armhf-2016-10-06-2gb

My configuration (i have deactivated renaming over udev/rules.d/70-persistent-net.rules)

#auto wlxe46f13296891
#iface wlxe46f13296891 inet static
auto wlan0
iface wlan0 inet static
address 192.168.4.1
network 192.168.4.0
netmask 255.255.255.0
broadcast 192.168.4.255
hostapd /etc/hostapd/hostapd.conf

When restarting network service it works successfully: ifconfig
