Dear Damyan,


today I had access to the concerning EeePC 701 4G again.

I had to run it as root and did

        $ sudo sh -x /etc/acpi/actions/wireless.sh on
        + wlan_control=/sys/devices/platform/eeepc/wlan
        + [ -e /sys/devices/platform/eeepc/wlan ]
        + cat /sys/devices/platform/eeepc/wlan
        + [ 0 = 0 ]
        + modprobe -r pciehp
        + modprobe pciehp pciehp_force=1
        + echo 1
        + modprobe ath_pci
        + sleep 1
        + ifconfig ath0 up
        ath0: ERROR while getting interface flags: Kein passendes Gerät gefunden (translation: No suitable device found.)
        + exec /etc/acpi/actions/wireless.sh off
        
In my dmesg output (relevant parts attached at the end) I saw that udev
was naming the device wifi0. I substituted the respective lines

        $ sudo vim /etc/acpi/actions/wireless.sh

and it worked, i. e. the blue light stayed blue. I do not know if there
was a WLAN available.

So you were right. It looks like since 2.6.26 the devices are named
differently. Or does it depend on udev?

Does anyone know if there are already updated eeepc-acpi-scripts?

Sorry, I forgot to look into this. But it looks like this did not
matter.


Thanks a lot,

Paul


$ dmesg # Sorry, somehow not everything was saved (I used screen), so just the end.
