I have a Linux machine on raspberry that function as an access point.
Linux raspberrypi 3.18.7-v7+ #755 SMP PREEMPT Thu Feb 12 17:20:48 GMT 2015 armv7l GNU/Linux
And I have a DHCP server on it. in the /etc/network/interfaces I've defined a static IP address however whenever I start it I get an IP which is not the static one but rather from the DHCP server. This behavior is not consistent and sometimes I get the static IP.
this is a module as part of a project that function sometimes as an AP and sometimes as Client based on parameters in a script. some of the cases when changing back to AP it gets the IP wrong although the conf files are as below in all cases.
this is my hostapd.conf
interface=wlan0
driver=rtl871xdrv
ssid=my ssid
hw_mode=g
channel=6
auth_algs=1
ieee80211n=1
this is my interfaces file

ping to 192.168.0.1 was changed to 192.168.0.33 and got destination unreachable ping to 192.168.0.33 works
the eth0 didn't get an IP.
