    Default 3945abg detected, freezes on load

    hello,
    I'm working on a hp dv6000 laptop with the bt2 live cd. It has the 3945abg wireless card in it.
    dmesg tells me that the card is indeed detected:
    Code:
    ipw3945: Intel(R) PRO/Wireless 3945 Network Connection driver for Linux, 1.2.0dm
    pr
    ipw3945: Copyright(c) 2003-2006 Intel Corporation

    ifconfig -a only gives out lo, neither the wired network card
    Code:
    bt ~ # ifconfig -a

              inet6 addr: ::1/128 Scope:Host

              collisions:0 txqueuelen:0
              RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)
    Trying to load the card as pointed out in various threads lets bt2 freeze. My guess is that it has to do with a problem running the unload:

    Code:
    /usr/src/drivers/ipw3945-1.2.0/load: line 14: ./unload: No such file or directory
    Running unload manually beforehand leads to:
    Code:
    bt ~ # /usr/src/drivers/ipw3945-1.2.0/unload
    Unloaded: ipw3945 ieee80211 ieee80211_crypt
    bt ~ # /usr/src/drivers/ipw3945-1.2.0/load
    /usr/src/drivers/ipw3945-1.2.0/load: line 14: ./unload: No such file or directory
    ipw3945d - regulatory daemon

    2007-07-20 11:55:05: ERROR: Could not find Intel PRO/Wireless 3945ABG Network Connection
    ..done.

    Any help would greatly be appreciated. Thx in advance.

    try this:

    Code:
    modprobe ipw3945
    /usr/src/drivers/ipw3945-1.2.0/load
    The answer is 42.

    First off all thank you for the quick response.


    I tried what you suggested and on the first try the system frooze. Probably because of the ./unload error in the load script.
    Then I gave it a second try, unloading manually, then entering modprobe and load. I got a response like " Intel Wireless 3945 blablabla found at ..."
    sounded good to me.
    ifconfig -a still didnt list the wireless card. lo was the only entry.

    Hoping that you can give me more advice.
    Thanks

    If you have the ipwraw drivers installed, also try:
    modprobe -r ipwraw

    Then:
    modprobe -r ipw3945
    modprobe ipw3945
    load

    Just to make sure everything is clear.

    Thanks for the replies.

    Unfortunately I didn't get the desired results.
    Trying loading from the menu does unload the drivers correctly and states that tha card is found, but then it freezes. Unloading manually beforehand didn't change the outcome.

    Doing what PsySpy suggested had the same outcome. The system finds the card and then freezes.

    The last words on the screen are:
    Exiting.
    .. (two dots)
    at that point nothing reacts anymore.

    Hopefully there is a way to solve that problem. Thanks for the support so far.

    You should be using this method after you first boot up :
    Code:
    /usr/src/drivers/ipw3945-1.2.0/ && ./load
    or
    Code:
    /usr/src/drivers/ipw3945-1.2.0/load;sudo -s
    Code:
    ERROR: Could not find Intel PRO/Wireless 3945ABG Network Connection
    ..done.
    This error message is common after unload for some reason.

    try this
    Code:
    cd /usr/src/drivers/ipw3945-1.2.0
    load
    This method works when switching from IPWRAW to IPW3945 drivers for me fine.

    hey,
    thanks for the input PrairieFire, but they didn't work for me. Still halting my system every time I try a method.

    Hope there is a solution somewhere.

    trying the ipwraw driver I get this result. Might help in detecting the problem:

    Code:
    bt ipwraw # /tmp/ipwraw/load
    Loading 'ipwraw'...done.
    Waiting for /sys/class/net/wifi0/device/rtap_iface to appear....time out.
    Could not find wifi0 interface.
