A couple of things you can do with WEP (Wireless Encryption Protocol). A
former coworker actually wrote a perl script to rotate his WEP keys every two
hours. This is about the minimum time interval that it is possible to crack
WEP keys sniffing "normal" amounts of traffic.
Another option would be to set up the firewall to only accept, say, vpn
traffic, then use something like OpenVPN (http://openvpn.sourceforge.net)
and route all traffic from the wireless machine through the vpn tunnel. Ran
across an article yesterday on linuxsecurity.com called Best Practices For
Securing Your WLAN,
Haven't had time to review it, but there it is.
