Hi,
I can just confirm that atheros wifi and WPA is broken on 2.6.18-128.1.1.el5
kernel or later at least on one of my systems.
The "problem" seems to be that Redhat has added ath5k.ko in
2.6.18-128.1.1.el5 kernel. ath5k.ko was not yet there in 2.6.18-128.el5 and
older kernels.
At the moment I don't know why it's not working. As far as I see,
wpa_supplicant is not working with ath5k driver. And per default ath5k is
loaded even if madwifi is installed. Or you get even a mix of loaded ath
modules. See
/sbin/lsmod | grep ath
However, if I disable/remove ath5k.ko, madwifi is still not working???
There is a CentOS wiki article on the Atheros AR5007EG card. I don't
know if this is related, but there is some chance that the info on
that page might help.

It basically tells you to replace the current madwifi with the newer
version (from source), and blacklist ath5k.

Thanks for the link.
I just tried the latest madwifi snapshot and blacklist ath5k. But I had
no success :-(
So I started from scratch.
Since ath5k driver should make madwifi obsolete and it's now in the RHEL
kernel, I removed all madwifi related RPMs from my SL53 system.
Disabled wpa_supplicant with "chkconfig wpa_supplicant off" -
NetworkManager will start wpa_supplicant.
Afterwards I configure the wireless network adapter with
"system-config-network" by removing the old wireless adapter entry and I
add a new wireless device (wlan0). This should create a file
/etc/sysconfig/network-scripts/ifcfg-wlan0
TYPE=Wireless
DEVICE=wlan0
HWADDR=
BOOTPROTO=dhcp
NETMASK=
DHCP_HOSTNAME=
IPADDR=
....
And I had to manually correct /etc/modprobe.conf by adding the line
alias wlan0 ath5k
remove "alias wlan0 ath_pci"
Reboot and now I can connect to my WPA WLAN access point again! :-)
There is one drawback, if I shutdown/stop NetworkManager I get a kernel
panic :-(
Nevertheless I hope in case ath5k works nicely, madwifi on SL5 will be
obsolete.
