The stock F10 kernel should support the ar5413, according to the
ath5k
website.[1]  Is the ath5k module being loaded?  What does "lsmod |
grep ath" return?






 dm_multipath 17164 0
 ath5k 112520 0
 mac80211 173668 1 ath5k
 cfg80211 23816 2 ath5k,mac80211





The ath5k module is definitely loaded.  For NetworkManager to use your
wireless card, it must be present in HAL.  Run "lshal" from the
command line and see if "atheros" or "ar5413" appears in the output.



 No. Nothing like that there.


Hmmm. . ..  Other than looking through the log file and dmesg for
anything odd, I only have a couple of more things for you to try.

1.  Edit /etc/modprobe.conf and add "alias wifi0 ath5k", making sure
to include a blank line at the end of the file.  Then, reboot.


 NO /etc/modprobe.conf !!!!!!

 Why? This is probably why no sound either!

I was equally vexed when I found no /etc/modprobe.conf on my F10
installation.  I needed to add an modprobe option for my case's LCD
display to work properly.  Fortunately, creating the file and adding
the appropriate stanza worked.

So how do you start making /etc/modprobe.conf? And what to do for Atheros and sound. the /etc/modprobe.conf on an identical unit running Centos 5.2 has:

alias eth0 8139too
alias snd-card-0 snd-hda-intel
options snd-card-0 index=0
options snd-hda-intel index=0
remove snd-hda-intel { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-hda-intel


2.  If you can obtain your wireless card's MAC address, add an entry
to /etc/udev/rules.d/70-persistent-net, using what is
listed for eth0
as a guide.  (I don't know if modifying the udev rules in this manner
is considered the best practice.)


 Well it looks like something is recognized:

 # iwconfig wlan0
 wlan0 IEEE 802.11b ESSID:""
 Mode:Managed Frequency:2.412 GHz Access Point: Not-Associated
 Tx-Power=0 dBm

 Inter-| sta-| Quality | Discarded packets | Missed | WE
 face | tus | link level noise | nwid crypt frag retry misc | beacon | 22
 wlan0: 0000 0 0 0 0 0 0 0 0 0


Are you now able to see access points using NetworkManager and
nm-applet?  If not, does "iwlist wlan0 scan" list access points around
you?

#iwlist wlan0 scan
wlan0 Interface doesn't support scanning : Network is down

No wlan0 interface it seems.

If neither of the above work, file a bug (my guess would be against
HAL or udev) and use the madwifi packages from rpmfusion or atrpms
until the bug is fixed.

 Challenge with atrpms is kernel patching. I got to like the dkms approach
that is available via rpmforge for Centos. I was hoping that things would be
more integrated...


If you like the dkms approach, you should check out the akmod-madwifi
packages in the rpmfusion repo.  From my understanding, akmod packages
are similar to dkms packages in that a new module is compiled when a
new kernel is installed.  I have yet to use any of the akmod packages.
 I'm waiting till amd releases an fglrx driver that works with F10,
but that is another thread.

How closely linked is the compile of akmod packages and releases of new kernels?
