[Voyage-linux] hostapd & ath9k

[Kim-man 'Punky' TSE]

Hi Frank,

For 11n-based atheros card, ath9k is the right module. 

1) Please read http://wireless.kernel.org/en/users/Drivers/ath9k for 
information on ath9k driver
2) You will need to install iw tools, which is available at 
http://www.voyage.hk/dists/0.6/iw/. 
3) Then read http://wireless.kernel.org/en/users/Documentation/hostapd 
for configuration.  Probably you only need:

interface=wlan0
driver=nl80211
channel=11
hw_mode=g

in /etc/hostapd/hostapd.conf + the suggested configuration in /README
4) Of course, don't forget /etc/network/interfaces
auto wlan0
iface wlan0 inet static
        address 10.1.10.1
        netmask 255.255.255.0
        broadcast 10.1.10.255
        up nat.sh wlan0 eth0 "10.1.10.0/24"

However, I have problem to get my iPhone connected and probably need 
more time to investigate.  Let me know if there are successful reports 
on ath9k with Voyage Linux.

Regards,
Punky
