    When you get the driver/firmware issues straightened out, you should open the "Network" program and configure the wireless device.

    The iwl3945 module is not loading.

    What happens if you do
    Code:
    su -
    modprobe iwl3945
    depmod -a
    Any errors? After, does
    Code:
    lsmod | grep iwl3945
    return the module?

    Hi Sunita,
    If you have uninstalled ipw as per reed9's instruction then its fine. Now, if you are sure you installed iwl3945, you can check it with
    Code:
    rpm -qa iwl*
    it should give you message like this(on my CentOS system)
    Code:
    [root@centos ~]# rpm -qa iwl*
    iwl3945-firmware-15.28.1.8-2.nodist.rf
    If you don't get any reply, it means the package is not installed. Check with,
    Code:
    root@centos ~]# yum search iwl
    Loaded plugins: fastestmirror, priorities
    Loading mirror speeds from cached hostfile
     * addons: centos.aol.in
     * base: centos.aol.in
     * extras: centos.aol.in
     * rpmforge: fr2.rpmfind.net
     * updates: centos.aol.in
    ================================= Matched: iwl =================================
    iwl3945-firmware.noarch : Firmware for Intel Wireless 3945 network adapter
    iwl4965-firmware.noarch : Firmware for IntelĀ® Wireless WiFi Link 4965AGN
                            : network adapter
    iwl5000-firmware.noarch : Firmware for IntelĀ® Wireless WiFi Link 5000AGN series
                            : network adapters
    then you can install it with
    Code:
    yum install iwl3945-firmware
    Once you have installed, do
    Code:
    modprobe -r iwl3945
    modprobe iwl3945
    It should not return any error. No reply means the module is loaded fine.

    Guess, you have named your router. That will be your essid. Switch on your wireless (have entry in 'ifconfig' for wlan0) and do
    Code:
    /sbin/iwconfig wlan0 essid "yourESSID"
    if you type '/sbin/iwconfig wlan0' it should show your router's name in essid place. Mine for your ref:
    Code:
    [root@centos ~]# iwconfig wlan0
    Warning: Driver for device wlan0 recommend version 21 of Wireless Extension,
    but has been compiled with version 20, therefore some driver features
    may not be available...
    
    wlan0     IEEE 802.11  ESSID:"SV"
              Mode:Managed  Frequency:2.462 GHz  Access Point: Not-Associated
              Tx-Power=14 dBm
              Retry min limit:7   RTS thr:off   Fragment thr=2352 B
              Encryption key:off
              Link Quality:0  Signal level:0  Noise level:0
              Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
              Tx excessive retries:0  Invalid misc:0   Missed beacon:0
    Now, we need to get ip address for wlan0. For some strange reason, I have found its better to use 'system-config-network' command than to try '/sbin/dhclient wlan0'. God knows why, 'dhclient' never was able to assign ip to wlan0 while 'system-config-network' did. *shrugs*

    P.S.:
    a) If you have enabled passsword on your router (i.e., WEP or WPA) disable them. Its better to start with plain connection.
    b) Wireless with CentOS (may be with RedHat) has been hit-and-miss for me. May be because the modules etc. are backported to build support on an old kernel...?! See the error on my 'iwconfig' output?

    Good luck.

    I think your kernel is too old to have this driver included. This driver wasn't included until RHEL 5.3 or kernel >= 2.6.18-128. An upgrade would solve that problem.

    Also, as I mentioned before, since you don't seem to have a licensed copy of RHEL, you would probably do better to move to one of the free RHEL clones, Scientific Linux or CentOS.

    Or, if you're not running an Enterprise distro for a reason, you might want to look at more general purpose desktop distros.
