If your <section begin=exclude />{{Message/Information Message|title=|message= In this guide is used [[ IGEP Processor Board has '''wifi interface''' you can connect to it.firmware Yocto ]]}}<section end=exclude />=== 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:
*IGEP Processor Board with WIFI *Host computer with WIFI *[http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html PuTTy program]<brsection begin=wifi_connect />=== Connect to IGEP network ===
Follow these steps to connect to your IGEP device:  *Click on the Network Manager Tray icon. *Select IGEP_&lt;xx&gt; network, where &lt;xx&gt; is different for every IGEP device, to connect. {| width="100%" cellspacing="1" cellpadding="1" border="01" alignwidth="center200"

! scope="row" | [[Image:InformationIgep wificon1.jpgpng|60x60px331px]] | If this is your first time accessing your IGEP Processor Board, it is highly recommended that you [[Update the PRE-INSTALLED software image to a current releaseImage:Igep wificon2.png|update your pre-installed software image to a recent release331px]] to ensure you have the latest features and bug fixes.

=== Download Boot and Rootfs Connect to IGEP ===
You can download the boot partition and the rootfs partition packages from hereFollow these steps to get a remote shell prompt:
*[httpOpen PuTTy program *Host Name://downloads192.igep168.es/files/IGEP_Mod_linaro/boot-linaro_minimal6.10.10.tar.bz2 Boot Partition] 1 *Port: 22 *[httpConnection type://downloads.igep.es/files/IGEP_Mod_linaro/rootfs-linaro_minimal.10.10.tar.bz2 Root File System]<br>SSH *Click Open, accept Security Alert and login as root user
<br>  {| cellspacing="1" cellpadding="1" border= Create a Boot MicroSD Card<br> =="1" width="200"|-Now create a Boot MicroSD Card using the two packages above. Follow this HowTo from the IGEP Wiki:  *| [[How to boot from MicroSD CardImage:Igep wifiputty1.png|How to boot from MicroSD Card331px]]. '''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 wifiputty2.png|331px]] So, the path to the ''interfaces'' file will be like: ''/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 configuration.<br>  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| [[Image: ''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'''Igep wifiputty3.<br> png|331px]]  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| [[Image: <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 192Igep wifiputty4.168.1.44png|331px]]  netmask 255.255.255.0|}

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. <section end=wifi_connect /pre> You are now ready to [[Using SSH to communicate|connect to your board via SSH]], for example. === Troubleshooting ===
