Hi Chris,

I used the following script to workaround the `service netif restart` panic.
Hope you will find help.

#!/bin/sh

NUM_INPUT=$#
display_usage() {
        echo "This script only supports two input arguments."
        echo -e "\nUsage:\n$0 <mode> <channel>\n"
}
# check whether user had supplied -h or --help. If yes display usage
if [ "$1" = "help" -o "$1" = "-h" ]; then
        display_usage
        exit 0
fi
# if other than two arguments supplied, display usage
if [  $NUM_INPUT -ne 2 ]; then
        display_usage
        exit 1
fi

MOD=$1
CHN=$2
echo "working on bring up the wlan0 and testing 802.$MOD channel $CHN"

kldunload if_iwlwifi && sleep 1
kldload if_iwlwifi && sleep 1

if [ "$MOD" = "11b" -o "$MOD" = "11g" ]; then
        wpa_passphrase "SSID" "****" > /etc/wpa_supplicant.conf
        ifconfig wlan0 create wlandev iwlwifi0 regdomain fcc country US ssid
SSID mode $MOD channel $CHN
elif [ "$MOD" = "11a" ]; then
        wpa_passphrase "SSID" "****" > /etc/wpa_supplicant.conf
        ifconfig wlan0 create wlandev iwlwifi0 regdomain fcc country US ssid
SSID mode $MOD channel $CHN
fi
sleep 1

ifconfig wlan0 up && sleep 1
ifconfig wlan0 scan && sleep 1
wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant.conf && sleep 2

dhclient wlan0 && sleep 2

echo "test done!"
