The series of patches (attached) resolve following problems:

- Fix a failure of regstering callback furnction for WLAN
- Rename ath6kl for both Ubuntu and Android to let WLAN middleware
  to use the existing module name.
- Fix scanning/ connection problem.

And this patch is based on

WiFi works well on Origen hardware pack:

On Origen board with Linaro ubuntu pre-built image:

http://snapshots.linaro.org/precise/pre-built/leb-origen/273/leb-origen-precise_ubuntu-desktop_20120812-273.img.gz

My WiFi access point can't be found. However, the board can find other access points. I tried to configure it manually in network manager, but doesn't work.

The weird thing is the access points which show up are those ones with weak signal. My wireless router is just around 30cm beside the board but can't be shown. I disable & enable the wireless function in network manager, but got same result unfortunately.

The WiFi access point in my wireless router is running with WPA2 PSK encryption, and it works well on all my other electronic devices.

@Sangwook, would you help me to double check this feature on your side? The SD card flashing command is:

sudo dd if=leb-origen-precise_ubuntu-desktop_20120812-273.img of=/dev/sdd bs=4M

On Samsung Origen board, with Linaro pre-built image:

WiFi works well again.
