    CentOS 6 can't see or set up wireless card


    Hello All,
    I am a Newbb to Linux and to CentOS 6 I have been working hard at figuring this out.

    My PC:

    AMD Phenom(tm) II X4 970 Processor (4 cpu cores) (version 2.20.00)
    64 bit 3.5 ghz
    4 gigs ram

    What does work so far:

    Installed CentOS 6 with raid 5 on 3 HDD's
    Boot up automatically to gnome GUI
    Installed ETH0 ethernet and it works


    Problem:
    wireless card not detected "I think"

    So far I have tried from google searches:

    First, you set up the ELRepo repository by running (as root):
    == BEGIN rpm --import http://elrepo.org/RPM-GPG-KEY-elrepo.org
    rpm --import http://elrepo.org/RPM-GPG-KEY-elrepo.org
    == END rpm --import http://elrepo.org/RPM-GPG-KEY-elrepo.org

    == BEGIN -Uvh http://elrepo.org/elrepo-release-6-4...epo.noarch.rpm
    rpm -Uvh http://elrepo.org/elrepo-release-6-4...epo.noarch.rpm
    == END -Uvh http://elrepo.org/elrepo-release-6-4...epo.noarch.rpm

    Then you install kernel-ml by running (as root):
    == BEGIN yum --enablerepo=elrepo-kernel install kernel-ml
    yum --enablerepo=elrepo-kernel install kernel-ml
    Installed:01/20/2013 trying this for my wireless nic
    kernel-ml.x86_64 0:3.7.3-1.el6.elrepo
    == END yum --enablerepo=elrepo-kernel install kernel-ml

    Reboot the machine. When you get the grub menu, select the newly installed kernel.
    It must be at the top of the list and has elrepo in the name.
    Boot it and see if your USB wireless now works.

    == BEGIN cat /etc/redhat-release
    [root@centOS John]# cat /etc/redhat-release
    CentOS release 6.3 (Final)
    == END cat /etc/redhat-release

    I have tried different kernels current one is


    == BEGIN uname -rmi
    [root@centOS John]# uname -rmi
    3.7.3-1.el6.elrepo.x86_64 x86_64 x86_64
    == END uname -rmi

    == BEGIN rpm -q kernel
    [root@centOS John]# rpm -q kernel
    kernel-2.6.32-220.el6.x86_64
    kernel-2.6.32-279.19.1.el6.x86_64
    == END rpm -q kernel



    More Stuff:


    == BEGIN ifconfig -a

    07:05.0 Network controller: Ralink corp. RT2800 802.11n PCI
    == END lspci | grep -i net

    Do I need a more friendly wireless card?
    Should this be this difficult?
    Am I missing something?

    Please advise

    Thanks

    I had the same problem when I first installed Fedora several months ago. I had to change the network manager that is used by the desktop. WICD wouldn't work for me, and neither would an app called "network" (IIRC). I finally got it to work with NetworkManager. I also had to make sure that only one of those were installed.

    I think you need to download a firmware blob but the name might be different on your system. On the Gentoo repos it's called rt2860-firmware. Do a search in your repo and see if you can find a similar package name.

    Try this link.

    https://www.centos.org/modules/newbb...30192&forum=40

    Where did you find this part?
    Then you install kernel-ml by running (as root):
    == BEGIN yum --enablerepo=elrepo-kernel install kernel-ml
    yum --enablerepo=elrepo-kernel install kernel-ml
    Installed:01/20/2013 trying this for my wireless nic
    kernel-ml.x86_64 0:3.7.3-1.el6.elrepo
    == END yum --enablerepo=elrepo-kernel install kernel-ml
