Installation of Internet on beagelboard (Angstrom, Debian, ubuntu, ...)

the first task after reception of beagelboard was to connect it to internet.
step of connection:
1) connect the usb key in the USB hub and check if the driver is installed
CMD: usb-devices
2) configure interface Wlan0
CMD: config wlan0 up
3) verification it's up
CMD: ifconfig wlan0
4) detect all wifi interfaces environment
CMD: iwlist wlan0 scanning
5) convert the WPA key into hexadecimal key
CMD:
6) Open the WPA configure file
CMD: vi /etc/wpa_supplicant.conf
6 bis) If doesn't exist you must install with the command
CMD: opkg install wpasupplicant
7) Insert the next block into the file wpa_supplicant.conf (the psk
code is a result of the step five)
# Only WPA-PSK is used. Any valid cipher combination is accepted.
network={
       ssid="Freebox-Coloc"
       proto=WPA
       key_mgmt=WPA-PSK
       pairwise=TKIP
       group=TKIP
       psk=c6b49...42d135a4
       priority=2
}
8) Now open the interface file
CMD: vi /etc/network/interfaces
9) and insert the next lignes (this configuration connect internet
before opening the session)
       auto wlan0
       iface wlan0 inet static
#XXX == choose the available address in your network
       address 192.168.1.XXX
       netmask 255.255.255.0
       network 192.168.1.0
       broadcast 192.168.1.255
       gateway 192.168.1.1
       wpa-conf /etc/wpa_supplicant.conf

normally you should be connected to internet ^^
