Thanks for your help! I was finally able to get it to work with the
following, which I put into a script:
/etc/init.d/wicd stop
ifconfig $IFACE down
iwconfig $IFACE essid $ESSID mode Ad-Hoc channel $CHANNEL
ifconfig $IFACE up $IPADDR
iwconfig $IFACE essid $ESSID mode Ad-Hoc channel $CHANNEL
route add default gw $DEFAULTGW $IFACE
Adding google dns into resolv.conf allowed me to successfully get
internet. I now have a couple of questions:
1. Why do I have to call iwconfig twice?
2. Is wicd at fault in this case? If so, should I file a bug report?
