    Default wireless stopped working

    hello
    i'm running suse 10.3 on a gateway laptop, the wireless card had always worked fine but suddenly it stopped, and now ethernet is the only way to network,

    i have checked yast > network settings and it says

    Wireless Network Card (not connected)
    BusID : 0000:04:00.0
    Unable to configure the network card because the kernel device is not present

    this error is very unexpected, i cannot explain why it happened, i used the install cd to reinstall the system but it failed to configure the network card

    i want to know what configuration changed on my system, i really need to fix this because right now i don't have the time, and i need to work on the laptop using wireless

    and i'm sure it works fine, i have used suse on this laptop from two months or so..

    thanks for your help and advise

    What does the output of dmesg have to say about your wireless card?

    this the hardware info,
    the iwl3545 drivers and the microcodes seem to be installed, but something failed and now the wireless network adapter is 'not configured', kernel device not present

    Where does this say that the firmware is OK? Please check the output of dmesg to
    see what it says.

    Default Re: wireless stopped working

    Did some googling for this problem and found this.
    Would it have anything to do with your laptops wireless card hot key like it says here?

    Kill switch must be turned off for wireless networking to work.

    The last two lines were a worry, but Jacques Vuillemin suggested that Fn-F2 is the magic to turn off the Kill Switch. If this doesn't work then modify the BIOS (F2 on boot) to disable the wireless hotley. The wireless load command worked for me after Fn-F2
    Hope it helps.

    Probably the consequence of a kernel update which didn't bring a working
    driver for your wireless card with it.

    What type (manufacturer, model) of wireless card is it? What did you do
    to get it to run initially? If you installed any driver module for it
    that is not in the mainline Linux kernel, you might have to reinstall it.
