    atheros wlan on hp nc8000

    I'm having trouble activating the wlan interface on my notebook
    I'm running FC3 with all the latest patches and atheros drivers

    I'm able to activate the card under windows with no problems and
    it can access the internet via the gateway

    While under linux the blue wlan light on the notebook is off while under
    windows it's on - does this matter?

    It looks like everything is up and running and should be working. You don't have iptables running blocking pings on either host do you? I have an Atheros card too (am typing this over it) and everything looks right. Can you explain more about your IP configuration on both your host and your gateway (192.168.1.100)? Is your gateway your access point? Is the 192.168.1.101 address assigned on your laptop assigned via DHCP or is it static? Is there any sort of MAC filtering being done on your access point? Can I assume that by latest patches and drivers you mean you are running the latest kernel and are running the latest madwifi CVS?

    ftp/wget don't work either
    1.101 is my static ip
    1.100 is the wireless access point/dns/default gateway
    MAC Address Control is disabled on the wap
    FC3 latest kernel
    madwifi from: http://pipiche.free.fr/Downloads/Fed...0217-1.src.rpm

    What does this output:

    # ping -b 192.168.1.255

    and this:

    # arp -a

    Did you install the correct madwifi drivers?

    I compiled the src and then modprobe ath_pci

    I always get the latest CVS and "make;make install" and they work perfect. Again, your drivers appear to be working though because your client can see the access point just fine according to the output of your commands. It appears layer 2 is working. layer 3 seems to be where the problem is.

    I guess I can try to compile from cvs

    Time to call it a night - Thanks for your help

    I compiled the src from cvs and I get the same results

    When I run system-config-network I get this error on stdout:



    Warning : Device ath0 has been compiled with version 17
    of Wireless Extension, while we are using version 16.
    Some things may be broken...

    To be honest I've never used system-config-network to configure mine but I did just run it and get the same error message. Like I said, I don't think the problem with the driver because it appears to be working. It's the layer 3 configuration that appears wrong (ip configuration). layer 2 communication appears to be happening. What does your /etc/sysconfig/network-scripts/ifcfg-ath0 have in it and would it be possible to see the configuration of your access point (sanitized of wep keys of course).

    Hmm, everything still looks good to me except you didn't provide your IP configuration of your access point. However, I do have one more setting in my ifcfg-ath0 file that you do not have:

    IWPRIV="mode 0"

    This may or may not still be required on mine but it was a while back. Other than that my setup looks just like yours (except I am using DHCP which I assume is not working in your current state). Do you use a static address on your Windows side as well?

    One other thing. Does your access point do any kind of logging? Can you turn the log verbosity up and check for error messages, or whether it sees your client trying to connect and if it is rejecting anything for any reason?

    I'm using the same static ip under windows without issue
