I'm facing a issue with my wireless configuration in Zentyal Linux Server. I configured my wifi network setting in /etc/network/interfaces like this :
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback
auto wlan1
iface wlan1 inet dhcp
wireless-essid <name>
wireless-key1 <key>
address 192.168.1.100
netmask 255.255.255.0
gateway 192.168.1.1
...
It is working fine but when i restart my Server. Network settings get removed every time and shows following lines only :
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback
Every time i have to write these settings again to start my wifi. What is going on, and how can I fix this ?
