Hello,

I am using the IGEPv2 board, alongside with IGEPv2 expansion board and running Linaro 12.0 through SD card (kernel : 2.6.37+).
I am trying to communicate with the board, through wifi, but I don't see the "IGEP_XXXX" network. If it is related with the expansion board, I have enabled at the igep.ini the "buddy=igep0022" command.
Is it possible to be done with Linaro? or the feature works only with the Yocto firmware only?

Thanks a lot!

    Hi liamd5,

    Linaro nano precise distribution doesn't have WIFI support out of the box. You will need to install wireless-tools package and configure /etc/network/interfaces file.

    I posted my tested configuration.

    Cheers!

    Hi pau,

    I have 2 questions:

    1) I installed the wireless-tools and I added at the /etc/network/interfaces file
    auto wlan0
    iface wlan0 inet dhcp


    However, is it ok to create the IGEP_XXXX network ? I don't want to access Internet with the board but connect other devices to the board through the IGEP_XXXX network.

    2) IF I do:
    ifconfig wlan0 up


    I get SIOCSIFFLAGS: Permission denied

    Any ideas about these?

    Thanks!

    Hi liamd5,

    In the last post, I forgot to attach my interfaces file:

    # interfaces(5) file used by ifup(8) and ifdown(8)
    auto lo
    iface lo inet loopback

    #ETH
    auto eth0
    iface eth0 inet dhcp

    #WIFI
    auto wlan0
    iface wlan0 inet static
    address 192.168.13.1
    netmask 255.255.255.0
    wireless-channel 1
    wireless-essid MYNETWORK
    wireless-mode ad-hoc


    Try to connect to IGEP MYNETWORK network using a static IP between 192.168.13.1 to 192.168.13.254.

    If you want to use dhcp, you will need to install and configure a dhcp server to IGEP. Look the udhcp program from Yocto as an example

    Cheers!

    Hi Pau,

    Thanks for your answer. I modified my file according to yours but I don't see any IGEP_*** network when searching from other devices

    Cheers

    Hi Pau,

    The board finds the local wifi networks, but I can't see the IGEP_*** at my laptop.

    Thanks!

    Hi liamd5,

    You should see "MYNETWORK" network in channel 1. Change wireless-essid parameter with your desired essid name. I tested with my mobile phone.

    Hi Pau,

    Thanks a lot for your help! Yes, I see "my network" now. I managed to connect (only in Windows environment not from Ubuntu), but I couldn't access the board using:

    ssh -p 22 linaro@192.168.13.1
    at Putty.

    Cheers!

    Hi liamd5,

    Before connect to SSH, check your WLAN network configuration in windows:
    - address: a static IP between 192.168.13.2 to 192.168.13.254
    - netmask: 255.255.255.0

    Try to connect with root user, by default, root doesn't have password

    Cheers!
