I have followed the handbook "30.3.6 Freebsd Host Access Points" Chapter 
in setting up this ath0 wifi card that is installed into my gateway box 
that has a LAN on it. A win7 laptop can see the ssid and connect to it. 
But it can not gain public internet access. Win7 wifi trouble shooting 
says no valid ip address and not end point. To me this sounds like a 
network configuration problem on my Freebsd gateway box.

This general config has been working for many years, since release 3.0 
of Freebsd. The only thing new is the wifi card being used as a gateway 
hostap.

I do not understand what this is doing
fconfig_wlan0="inet 10.0.10.100 netmask 255.255.255.0

I can not find any documentation on this as to it's purpose.

I am trying to duplucate my cisco wifi router config which has this
security mode = wpa2 personal
encrytion = tkip or aes
network mode = BGN


Thanks for any help you can give me
