It seems to be a hardware problem.  You might want to check /sys/class/gpio/gpio16/value to make sure it is '1', though I don't know why it won't be.

I have the libertas and libertas_sdio modules, however they are not loaded at boot.

If I manually load them using 'modprobe libertas' and 'modprobe liertas_sdio' they load just fine, but wlan0 still doesn't show up. Do I have to create the device file manually?

If I grep for LIBERTAS in /proc/config.gz I get the following:

# CONFIG_LIBERTAS_THINFIRM is not set
CONFIG_LIBERTAS=m
CONFIG_LIBERTAS_USB=m
CONFIG_LIBERTAS_SDIO=m
# CONFIG_LIBERTAS_SPI is not set
CONFIG_LIBERTAS_DEBUG=y
# CONFIG_LIBERTAS_MESH is not set

The Overo Air I'm using is brand new and hopefully isn't broken...

Hm... You can try "modprobe -l | grep libertas" to see if the module is installed.  Alternatively you can also gunzip /proc/config.gz, and search to see if CONFIG_LIBERTAS=m is in the kernel config file.  If the module is installed, then you might have bad hardware.

Here is what I have tried.

I created a bootable sd-card based on the most recent overo image I could find, which I downloaded from:
http://cumulus.gumstix.org/images/angstrom/factory/2011-03-25-1619/

For now I run it directly from the sd-card.

At boot I do NOT get the messages I'm supposed to according to the guide you linked me, so the is no output during boot regarding libertas_sdio or libertas.

If I try commands like:
root@overo:~# iwconfig wlan0 essid any

I get the response:
Error for wireless request "Set ESSID" (8B1A) :
  SET failed on device wlan0 ; No such device.

I also tried to remove stop and remove the NetworkManager, which didn't help.

I also tried similar things on the factory installed image (running the 2.6.34 kernel) with similar results.

Any suggestions?

<http://wiki.gumstix.org/index.php?title=Overo_Wifi>What did you try?

Additional notes, the driver (at least the current one) does support power management, so iwconfig power on works.

Also, you need to make sure network manager is disabled, i.e.

/etc/init.d/NetworkManager stop
opkg remove networkmanager

Hi,

I'm having a problem with getting wifi running on my Overo Air board.

If I try commands like:

$ ifup wlan0

I constantly get this error:

SET failed on device wlan0 ; No such device

I'm using the default build from gumstix (2.6.34 kernel) with no modifications.

I tried the guides in the wiki etc but with no luck.

Any suggestions?

David
