    What distro are you using?

    Do you have the correct Driver installed?

    you can simply do a lspci -l

    Are you using ndiswrapper? do you have it linked correctly to the kernel?

    wpa_supplicant enabled?


    this is a good place to start...otherwise google linux and wireless...

    distro: SLED 10

    controller: 10:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG Network Connection (rev 02 )

    not use ndiswrapper

    where is wpa_supplicant?

    I used google before posted this topic.

    after start does not plug into wifi network I have wait lots(maybe 75 sec) . I dont know how modify this time.

    If I understand you correctly, it does eventually connect, but it takes about 75 seconds, and then it will die out? or do you maintain connection?

    I believe the issue is that specific card has had issues with compatibility. I googled and found this to be helpful.


    I read this, and it sounded similar to your issue.


    and about wpa_supplicant...

    it would be in the sessions, down towards the bottom of list, if it is installed...

    go to services ....

    find wpa_supplicant, check and hit enable....

    if it enables...then you have wireless, otherwise it will give you an error...you should post that error so that we can see what the problem is.
