    Default Intel Pro Wireless 3945abg

    What does it take to get this wireless card working in Suse 11?

    It is detected but shows not connected.

    Does it display WLAN networks at all?
    If not, try this:
    As root, touch /etc/modprobe.d/iwl3945. Edit the file and add

    alias wlan0 iwl3945
    options iwl3945 disable_hw_scan=1

    then reboot.

    Thanks Uwe but still no joy.

    In Gnome the network manager Wireless is still greyed out.

    In Yast the card shows not connected.

    Acer TravelMate 4220

    Sorry but I'm not sure I understand.

    I have toggled the physical switch on the laptop with no change. No led.

    Perhaps the Gnome Keyring is blocking it.

    In Yast I edited the config again and tried the Hotplug option.

    Clicked finish and got a warning box about not being able to connect to skynet repo.

    Clicked skip several times and got Keyring prompt.

    Entered the Keyring password and BOOM got the wifi connection.

    Rebooted.


    This time when Gnome desktop loads I get the Keyring password prompt.

    Enter Keyring password and desktop loads and wifi connects :-)

    It seems Keyring blocked the wifi card until I did something that triggered the Keyring prompt.

    Seems to be working OK now:-)

    What do the commands "iwconfig" and "iwlist scan" say?
