    iwl3945 Not working on Hardy

    I tried to access the Internet off my Intel Pro/Wireless 3945 ABG (Centrino) card after upgrading from gutsy to hardy, and I cannot connect to my wireless router with any method.

    The card worked under gutsy with the ipw3945 driver, but with hardy, after switching to iwl3945, it no longer works.

    Heres a txt file with some data on the card. (Like iwconfig, etc) My AP name is 2WIRE882.

    Also, when I go to network tools, and try push the configure button on any network interface, it says that the Interface does not exist.

    So, what can I do, besides going back to gutsy?

    I tried a different distro based on Ubuntu, and it used iwl3945 as well, and it didn't work either.

    Do you happen to have a 2Wire router? I've found one other documented case where the iwl3945 driver does not work with a 2wire router.

    I would say this is a huge bug in the wireless part.

    I have a similar issue with hardy on x61s with intel 3495. I can connect to open wireless networks that broadcast but I loose connection after few minutes. The networkmanager indicates that its still connected to a wireless network but I don't have connectivity. The ipw3495 seems to be loaded but its not showing up on restricted drivers manager.

    Possible solution?

    Looks like its the network manager that is the problem here.

    Same problem here with my Dell D620 and Intel Pro/Wireless 3945 ABG. Worked fine with 7.10. Has anyone ben able to get anywhere with this issue?

    Re: iwl3945 Not working on Hardy

    This problem is still not solved but you can get wireless working by using ndiswrapper.

    Code:
    lsmod | grep iwl
    this will give you an output of the modules loaded to get iwl3945 working. The modules it shows are: iwl3945, iwlwifi_mac80211, cfg80211.
    Then we must make sure that these are not loaded again

    Code:
    sudo nano /etc/modprobe.d/blacklist
    and add:

    #iwl
    blacklist iwl3945
    blacklist iwlwifi_mac80211
    blacklist cfg80211

    then remove the modules:

    Code:
    sudo rmmod iwl3945
    sudo rmmod iwlwifi_mac80211
    sudo rmmod cfg80211
    then install ndiswrapper

    Code:
    sudo apt-get install ndiswrapper-common ndiswrapper-utils-1.9
    install the windows driver

    Code:
    sudo ndiswrapper -i drivername.inf
    make sure it starts at boottime, add ndiswrapper to /etc/modules

    Code:
    sudo nano /etc/modules
    Now reboot and all should be fine
