Need help configuring my network (PARTIALLY SOLVED)

I can get the interface to work now, but I need some help to automate the
process.
This is what I did.
1. In /var/log/syslog I noticed that ifplugd was bringing the interface up and
then down and up and down and up and down....you get the picture. For those
few brief moments when the interface was up, everything seemed to be
configured correctly. Finally, wpa_supplicant exited and nothing worked. So I
removed ifplugd.

2. This is how I get it to work manually
a. Reboot
b. wpa_supplicant -w -i ath0 -D madwifi
-c /etc/wpa_supplicant/wpa_supplicant.conf -B
c. ifconfig ath0 192.168.25.125 netmask 255.255.255.0 up
d. route add default gw 192.168.25.1
I thought if I just did /etc/init.d/network start I could avoid the last two
steps, but only lo comes up.
So, any suggestions would be appreciated. I know I can put these steps in a
startup script that I write, but that does not seem to be the correct
solution. I must be missing a configuration step in Debian/Linux to get this
working on boot up.
Also, any thoughts on why the ifplugd kept loosing the link and how to get
ifplugd working agin would be great! I was hoping to use this combination on
another computer.
Thanks!
