#! / bin/bashwhile! Iw dev wlan1 info & > / tmp/netlog; do sleep 0.2 done ifconfig wlan1 down iw dev wlan1 interface add ah0 type ibss ifconfig ah0 up iw dev ah0 ibss join RPI-ah0 2462 ifconfig ah0 192.168.2.6 route add 192.168.1.102 gw 192.168.1.102 dev wlan0 route add 192.168.2.102 gw 192.168.2.102 dev ah0

(3) set the executable permission of the mynet.conf file, open the terminal and enter the following command:
