you have to choose how net access will go on your laptop. check out
tools like ifplugd and others. they can help you to automagic choose the
right interface when a cable is plugged in or an specific accesspoint is
in range. with the right options/configuration.

$ apt-cache search laptop network
$ apt-cache show ifplugd
 
use /etc/network/interfaces to assign an ipaddress and network to your
ath0, the route will be set automagically if hotplug (see
/etc/default/hotplug) finds your atheros plugged in:

<snip>
auto lo eth0
iface lo inet loopback

# NE2000 DLINK
# static routing using home gateway - cardmgr takes care
iface eth0 inet static
        address 192.168.2.52
        netmask 255.255.255.0
        network 192.168.2.0
        broadcast 192.168.2.255
        gateway 192.168.2.50

# WIRELESS
# static routing using home gateway - hotplug takes care
iface ath0 inet static
        address 192.168.2.52
        netmask 255.255.255.0
        network 192.168.2.0
        broadcast 192.168.2.255
        gateway 192.168.2.50
        wireless_mode managed
        wireless_channel 1
        wireless_essid XXXXXX
        wireless_key XXXXXXXXXXXXXXXXXXXXXXXXXX

</snip>

read the interfaces and hotplug manpages about the auto flag. above is
my network - yours sure looks something different. my eth0 is a pcmcia
card  which is handled by the cardmanager (cardmgr). i seldom have
plugged in both, and if i do, i have to set my route by hand:

route add -net 192.168.2.0 netmask 255.255.255.0 ath0

man route.
