[Voyage-linux] hostapd & ath9k

[Frank Parker]

Apologies for replying to myself, but I have some progress to report...

I forgot I still ath_pci module loaded instead of ath9k, from a
previous attempt to get madwifi working.  So I dif "rmmod ath_pci" and
"modprobe ath9k" then hostpapd started without error.

voyage:~# /etc/init.d/hostapd start
Starting advanced IEEE 802.11 management: hostapd.

voyage:~# ps ax | grep host
 4105 ?        Ss     0:00 /usr/sbin/hostapd -B -P
/var/run/hostapd.pid /etc/hostapd/hostapd.conf


I still don't have the config quite right (see below) because the SSID
is not visible to any of my wireless clients

If someone could give me a clear example of what goes into these
files, I would greatly appreciate it:

/etc/hostapd/hostapd.conf
/etc/network/interfaces
/etc/default/hostapd
Others?
