Using IGEP WLAN to communicate
From IGEP - ISEE Wiki
If your IGEP Processor Board has wifi interface you can connect to it.
You can open a SSH session in your computer and interact with your Board from your console. Here is how to.

Update pre-installed software
|
If this is your first time accessing your IGEP Processor Board, it is highly recommended that you update your pre-installed software image to a recent release to ensure you have the latest features and bug fixes. |

..or you can directly:
Download Boot and Rootfs
You can download the boot partition and the rootfs partition packages from here:
Create a Boot MicroSD Card
Now create a Boot MicroSD Card using the two packages above. Follow this HowTo from the IGEP Wiki:
- How to boot from MicroSD Card. Note: Just follow the 2nd point “Preparing the MicroSD Card” to create the two partitions needed.
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.
Configure the network
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: boot and rootfs. They are mounted in your '/media/' directory when you insert your MicroSD card to the host PC.
So, the path to the interfaces file will be like: /media/rootfs/etc/network/interfaces
Append this text file with the following commands:
# 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 '''<put here your Access Point SSID>''' wpa-ap-scan 2 wpa-proto RSN wpa-pairwise CCMP wpa-group CCMP wpa-key-mgmt WPA-PSK wpa-psk '''<put here your AP key*>'''
Complete the gaps with the missing information from your network configuration.
To set the same wpa-psk from your access point, execute this command in your PC (with wifi):
wpa_passphrase "Access Point Name" "WPA2 Pass Phrase"
This command gives you the wpa-psk key and you can replace it at the space from the file mentioned above: wpa-psk <put here your AP key*>
This configuration enables the wifi and automatically gets the IP from DHCP by default.
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
If you wish to use a static IP then you should change at the same interfaces file:
# 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 <put here your AP SSID>
wpa-ap-scan 2
wpa-proto RSN
wpa-pairwise CCMP
wpa-group CCMP
wpa-key-mgmt WPA-PSK
wpa-psk <put here your AP key>
address 192.168.1.44
netmask 255.255.255.0
gateway 192.168.1.1
You are now ready to connect to your board via SSH, for example.
Remember that the SSH connection details for this package are:
Username: root Password: letmein
