    Default open suse 11 intel 3945 wireless not connected

    Greetings all, hoping you can help

    well I switched to linux on this laptop cos my windows hdd died and refused to load back up again!! Thought I'd give opensuse a go as had some good reviews... Have to say it looks good!!

    Obviously am a newbie and dont know all of the commands, but have been reading these forums for help in trying to get wireless working... so far no joy!

    Below are my settings.... I'm using a HP COMPAQ TC4400. When I try and configure it just says not connected and when I try and use KWIFI Manager it just says no network found...

    My old thinkpad laptop running ubuntu can see router fine and my vista pc can see it fine so I know its not a problem with the router or any of the router settings...

    /sbin/lspci -nn

    I am using intel 3945ABG and inet 4965AGN which are able to connect to access poion on opensuse 11.

    Can you scan any access point by this command?
    #iwlist wlan0 scanning
    Please also verify your wireless nic like below example.
    # iwconfig
    lo no wireless extensions.

    eth0 no wireless extensions.

    wmaster0 no wireless extensions.

    Am I right in thinking that it can see my wireless in places, but not others??

    Same here,

    I have a Compaq HP nx 7400 with the 3945 card. Everything worked fine in openSUSE 10.3, keyboard let, enabling and disabling, swapping between wired B44 card and wireless I never had to spend a thought about it.

    After upgrading to openSUSE 11 I have to mess up my house with cables just to fill out this forum :-(.

    My other laptop still runs fine so no infra trouble. When I download, compile and install compat wireless I see networks for a brief moment but after that no more network, not even wired so I have to reinstall again. I've been working on this for 30 hours straight with no succes.

    Please help?

    Problem seems solved. I again installed the compat drivers but this time without unloading the old drivers. After that I threw my sweex WAP out off the window and installed a linksys.

    The new WAP has a 11a and 11g channel. only the 11g channel seems to work. Does that make any sence?
    You'll never get a second change to eat your first herring

    That's a know issue AFAIK, and it simply means the light doesn't shine :-)

    As root:

    touch /etc/modprobe.d/iwl3945

    Edit the file:
    alias wlan0 iwl3945
    options iwl3945 disable_hw_scan=1

    Reboot. Does it help?

    from what I can tell, I have the same problem as mitch1976:

    wlan is not supporting scanning, network is down.

    My wlan worked well enough before the kernel update to 2.6.25.16-0.1-pae.

    compilation and loading of compat-wireless did not appear to help (it has helped others)

    I have tried

    As root:

    touch /etc/modprobe.d/iwl3945

    Edit the file:
    alias wlan0 iwl3945
    options iwl3945 disable_hw_scan=1
    which after rebooting did not help.

    I am obviously a bit frustrated after hours of following forum advise. It also seems like reinstalling the old kernel does not return my wlan to its former glory. It is a pity that these security updates do not come with warnings. I do not need much security if I cannot connect to the internet - so perhaps this is the ultimate security update!

    I hope that someone who has had a similar problem could share their solutions.
