    Hi ratib, been a long time since I used Fedora or had to configure wireless but I'll try to help as best I can. First off, start here and go through the steps given. Good luck!

    sir, I tried all those commands to get some information posted there like,
    Code:
     lspci, lsusb, lsmod, ifconfig, iwconfig
    but I get bash: lspci: command not found.
    I also download the WirlessSetup.txt, and did run that file still the same: command not found.
    Yeah, i tried
    Code:
    uname -r
    the output is : 2.6.18-128.el5PAE
    waiting for your reply thanku

    In Fedora, I think you have to use exact path of utility like... /sbin/lspci, /sbin/ifconfig and so forth. Put /sbin/ in front of those commands. That should make them work. Some distros put those utilities in other places but I think they are all in /sbin/ in Fedora. Or, when becoming su, add a dash at the end as in:
    Code:
    su -
    And then those commands can be run as you have them listed.

    can't run ifconfig as su - FedoraForum.org

    EDIT: Looking back, you are using Red Hat but all this should still apply.

    EDIT TWO: I haven't been keeping up with Fedora but kernel 2.6.18 makes me think this is a very old version? You'll save yourself worlds of trouble by upgrading to newest version, (if that is the case) AND... paying the meager cost of support. Otherwise, I'd recommend swithching to Fedora or a less cutting edge/new-user-friendly-distro like Mint or SuSE.

    Still need to see lspci. Do su - as above then try just "lspci." We have to know what type wireless device you have... internal, external?

    Hi, ratib. I have to agree with Dapper Danon something. Updating to a more recent kernel will save you quite a bit of trouble.
    If you really require Red Hat as an OS, then you might want to look at version 6.3.
    It includes kernel 2.6.32, which may have a few needed drivers installed by default.

    Failing that, maybe a more detailed listing of your hardware would shed a little more light.
    Execute this in a terminal:
    Code:
    /sbin/lspci -knn
    Post back with the output.

    output is by typing
    Code:
    /sbin/lspci -knn
    /sbin/lspci: invalid option -- k
    Usage: lspci [<switches>]

    -v Be verbose
    -n Show numeric ID's
    -b Bus-centric view (PCI addresses and IRQ's instead of those seen by the CPU)
    -x Show hex-dump of the standard portion of config space
    -xxx Show hex-dump of the whole config space (dangerous; root only)
    -xxxx Show hex-dump of the 4096-byte extended config space (root only)
    -s [[[[<domain>]:]<bus>]:][<slot>][.[<func>]] Show only devices in selected slots
    -d [<vendor>]:[<device>] Show only selected devices
    -t Show bus tree
    -m Produce machine-readable output
    -i <file> Use specified ID database instead of /usr/share/hwdata/pci.ids
    -D Always show domain numbers
    -M Enable `bus mapping' mode (dangerous; root only)
    -P <dir> Use specified directory instead of /proc/bus/pci
    -H <mode> Use direct hardware access (<mode> = 1 or 2)
    -F <file> Read configuration data from given file
    -G Enable PCI access debugging

    This version is modified by Red Hat, so that it also takes all
    /usr/share/hwdata/pci.ids.d/*.ids files into account.

    sir, it is not necessary for me to use RedHat, if you want me to change to another version of linux which could solve this problem, then please suggest me which version should I use. thanks
