[Frank Parker]

Punky,
Thanks for the pointers.  Sorry for the dumb questions, I'm trying to
understand this.

Ok - I read this and I think this applies to my wireless card.

I installed iw with "apt-get install iw" since it was the same version 0.9.14-1.

I read this but I'm as confused as ever.

I replaced my existing hostapd.conf with the lines above.  Now these
are the only lines in hostapd.conf

Which steps of the README are you referring to?

So, what should I have in my /etc/network/interfaces at this point?
The lines above AND the ath0 lines from the README?  Both?


Here's what I have now:

voyage:~# cat /etc/hostapd/hostapd.conf
interface=wlan0
driver=nl80211
channel=11
hw_mode=g

voyage:~# cat /etc/network/interfaces
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

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"

auto ath0
iface ath0 inet static
        address 10.1.20.1
        netmask 255.255.255.0
        broadcast 10.1.20.255
        madwifi-base wifi0
        wireless-mode Master
        up iwpriv ath0 mode 3
        up iwconfig ath0 mode master
        up iwconfig ath0 essid voyage
        up iwconfig ath0 txpower auto
        up iwconfig ath0 enc off
        up iwconfig ath0 rate auto
        up nat.sh ath0 eth0 "10.1.20.0/24"


And here is the error I get:

voyage:~# /etc/init.d/hostapd start
Starting advanced IEEE 802.11 management: hostapdioctl[SIOCGIFFLAGS]:
No such device
 (warning).


Trying to start hostapd manually gives this error:

voyage:~# hostapd -dd -t /etc/hostapd/hostapd.conf
1266890173.877060: Configuration file: /etc/hostapd/hostapd.conf

Thanks for your patience.
