If your IGEP Processor Board has '''wifi interface''' you can connect to it.== Overview ==
If your IGEP Processor Board has '''WIFI interface''' you can connect to it without any cable. You can open a SSH session in your computer and interact with your Board from your console. Here is how to.
<br> == Requirements ==
== Update pre-installed software ==There are some requisites to follow this guide:
<br>*IGEP Processor Board with WIFI *Host computer with WIFI *[http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html PuTTy program]

<br>..or you can directly:== Connect to IGEP network ==
=== Download Boot and Rootfs ===Follow these steps to connect to your IGEP device:
You can download *Click on the boot partition and the rootfs partition packages from here: Network Manager Tray icon. *Select IGEP_&lt;xx&gt; network, where &lt;xx&gt; is different for every IGEP device, to connect.

'''Note''': Just follow the 2nd point “Preparing the MicroSD Card” to create the two partitions needed. <br>  Uncompress and untar the file ''boot|-linaro_minimal.10.10.tar.bz2'' in the '''boot partition''' and the file ''rootfs-linaro_minimal.10.10.tar.bz2'' in the '''rootfs partition''' of your MicroSD Card.<br>  == Configure the network<br> == To configure the wireless network in your IGEP Processor Board, you need to edit the ''/etc/network/interfaces'' file '''in your IGEP Processor Board''' (not your computer). To edit this file, remove the MicroSD from your IGEP device and insert it to your host PC.The MicroSD has two partitions| [[Image: boot and rootfs. They are mounted in your '/media/' directory when you insert your MicroSD card to the host PCIgep wifiputty3.png|331px]]  So, the path to the ''interfaces'' file will be like| [[Image: ''/media/rootfs/etc/network/interfaces'' Append this text file with the following commands: <pre> # interfaces(5) file used by ifup(8) and ifdown(8)  auto lo wlan0  iface lo inet loopback  iface wlan0 inet dhcp  wpa-driver wext  wpa-ssid '''&lt;put here your Access Point SSID&gt;'''  wpa-ap-scan 2  wpa-proto RSN  wpa-pairwise CCMP  wpa-group CCMP  wpa-key-mgmt WPA-PSK  wpa-psk '''&lt;put here your AP key*&gt;''' </pre> <br>  Complete the gaps with the missing information from your network configurationIgep wifiputty4.<br> png|331px]] To set the same wpa-psk from your access point, execute this command in your PC (with wifi):<br> <pre>wpa_passphrase "Access Point Name" "WPA2 Pass Phrase" </pre> This command gives you the '''wpa-psk key''' and you can replace it at the space from the file mentioned above: ''wpa-psk &lt;put here your AP key*&gt; ''<br>  <br>  This configuration enables the wifi and automatically '''gets the IP from DHCP by default'''.<br>  Therefore, when you boot the IGEP board you might have to get its IP from your Access Point, maybe in its management console or page if provided.  === Using static IP<br> === If you wish to use a static IP then you should change at the same interfaces file: <pre># interfaces(5) file used by ifup(8) and ifdown(8) auto lo wlan0  iface lo inet loopback  iface wlan0 inet static   wpa-driver wext  wpa-ssid &lt;put here your AP SSID&gt;  wpa-ap-scan 2  wpa-proto RSN  wpa-pairwise CCMP  wpa-group CCMP  wpa-key-mgmt WPA-PSK  wpa-psk &lt;put here your AP key&gt;  address 192.168.1.44|}

gateway Note that a DHCP IP address in range 192.168.6.10-192.168.6.254 should be given to your host PC. The IGEP device should have IP address 192.168.6.1.1
