Wireless network (and a shell script for you guys, also)

I don't know the right way to bring up my wireless iface at bootup, so I wrote a small shell script to do it for me.
Feel free to use it if you find it useful..

I'd also appreciate someone telling me what *IS* the arch way of doing what my shell script's doing

#!/usr/bin/env bash
#
# Val Polyakov <vxp@yoda.im>
# 7/8/07
#

#
# Change these to reflect your network
#
PATH=/usr/sbin:/sbin:/bin
IFACE=ifaceNameOfYourWirelessCard
DRIVER=moduleNameForYourWirelessCard
SID=yourSID
ENCKEY=yourEncryptionKey

#
# Don't change anything beyond this point.
#

case "$1" in
    start)
        echo "Loading the wireless card driver"
        modprobe $DRIVER
    echo "Setting up the SID and encryption key"
        iwconfig $IFACE essid $SID enc $ENCKEY
    echo "Bringing up the wireless interface"
    ifconfig $IFACE up
    if [ -f /var/run/dhcpcd-$IFACE.pid ]
    then
        rm /var/run/dhcpcd-$IFACE.pid
    fi
    echo "Running the dhcp client"
    dhcpcd $IFACE
        ;;
    stop)
        echo "Bringing down the wireless interface"
    ifconfig $IFACE down
    echo "Unloading the driver"
    rmmod $DRIVER   
    ;;
    restart)
        $0 stop
    sleep 2
        $0 start
        ;;
    *)
        echo "usage: $0 {start|stop|restart}"
    ;;
esac
exit 0

Network profiles are not working for me, though.

it didnt work for me either

i did set it up as directed in that wiki, by my essid kept getting set to "d" instead of "devnull" as I specified in the profile
so obviously that didnt work.

hence, wrote the shell script and stuck it in /etc/rc.d

Re: Wireless network (and a shell script for you guys, also)

If your wireless drivers support wpa_supplicant, you could try autowifi from http://www.archlinux.org/~thomas/autowifi-svn/ It handles multiple wireless networks very well. There is no documentation right now, just read here: http://archlinux.org/pipermail/arch-dev … 00867.html

what would the benefit of that be, as compared to my script ?
the shell script i made (and pasted) works just fine, sits in /etc/rc.d and is called by /etc/rc.conf

i was just curious whats the official, i guess, way to do it with arch

since network profiles dont work for some reason, i figured i must be missing something..
