Wireless Network setup

Intel supplied SD card image only includes iwlwifi-135-6.ucode and iwlwifi-6000g2a-6.ucode firmware. If you use WiFi card other than N-135 or N-6000, you will need to copy the proper firmwarE.

Once proper firmware is installed use the following steps to configure wireless (this assumes using WPA security).

1. Login to your Galileo as root

2. Run the following command to generate wpa_supplicant configuration file for your network. Replace MyWiFi with the SSID of your wireless networkand MyPassPhrase with the real passphrase:

root@clanton:~# wpa_passphrase MyWiFi << EOF > /etc/wpa_supplicant.conf
> MyPassPhrase
> EOF

3. If you wish to configure your Galileo to connect to the wireless network automatically, edit /etc/network/interfaces file and add auto wlan0 line somewhere in the file. I suggest putting it right before iface wlan0 line: /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)

# The loopback interface
auto lo
iface lo inet loopback

# Wireless interfaces
auto wlan0
iface wlan0 inet dhcp
        wireless_mode managed
        wireless_essid any
        wpa-driver wext
        wpa-conf /etc/wpa_supplicant.conf

4. Restart networking:

root@clanton:/etc# /etc/init.d/networking restart

5. You can also bring wireless interface up or down using ifup wlan0 and ifdown wlan0 command (even if you didn't enable auto connect in step 3):

root@clanton:/etc# ifdown wlan0
root@clanton:/etc# ifup wlan0
