Ärende: a simple wireless client bash script
============================================
Hey All!

A simple wireless client bash script to connect and disconnect.

Uses:  'ip' from iproute2 version 2.6.35
       'iw' from iw version 0.9.21

-------------- wireless.sh starts
#!/bin/bash
case "${1}" in
  start)
    if [ "$(find /proc/ -name wlan0)" ]
    then
      iw wlan0 set type managed
      ip link set wlan0 up
      if [ "$(iw wlan0 scan | grep "00:23:cd:13:4f:58")" ]
      then
        iw wlan0 connect oyster 00:23:cd:13:4f:58
        ip addr add 192.168.190.2/24 dev wlan0
      else
        ip link set wlan0 down
      fi
    fi
    ;;
    stop)
      ip addr del $client_address dev wlan0
      ip link set wlan0 down
      ;;
  *)
    echo "Usage: ${0} {start|stop}"
    exit 1
    ;;
esac
-------------- wireless.sh stops

For the record a scan of the wireless ap the above script connects to shows;

---------------------------------------------------------------------
root@xena [ ~ ]# iw wlan0 scan
BSS 00:23:cd:13:4f:58 (on wlan0) -- associated

wireless.sh is hardcoded to connect to the above ap and is easily modified to
enable connectivity to any working wireless ap.

The ap is an Intel Atom 230 soldered onto a D945GCLF mITX motherboard employing
an Atheros Communications Inc. AR922X Wireless Network Adapter which is run by
hostapd-0.7.3 and configs, bash init script are available by request.

Life is good,
Maurice
