Yes, you can put it in /etc/network/interfaces.  The stanza might look 
something like

iface home-wireless inet dhcp
  wireless-essid your essid
  wireless-mode managed
  wireless-channel 2
  wireless-key 1111-2222-3333-4444-AAAA-BBBB-CC

Don't put quotes around your ESSID.  You'll need the 'wireless-key' if you're 
using WEP.  See man iwconfig for the full list of wireless configuration 
options.  All the options defined in there go preceded by a "wireless-" if 
they're used in the interfaces file.

To bring the adapter up using that particular configuration run as root
$ ifup ath0=home-wireless

where ath0 is your device's name.  You can also have alternate configurations.  
For instance

iface work-wireless inet static
  wireless-essid work
  wireless-mode managed
  wireless-channel 2
  wireless-key off

and use it with $ ifup ath0=work-wireless for more details check man 
interfaces and man iwconfig.

If you move around a bit and really want to get fancy look here:  
You can apparently set up your laptop to automatically detect which network is 
available and choose the appropriate adapter configuration.  I haven't tried 
it myself (yet!).

Hope that helps.
