WiFi (non)Security ....

How can I protect my wireless network ? Well I found what NOT to use

1. Mac Filtering

Spoof the mac address in linux by ;

/etc/init.d/networking stop
ifconfig eth0 hw ether 00:01:02:03:04:08 <== desired mac :)
/etc/init.d/networking start

More info on other systems found here

2. WEP (Wireless Equivalent Privacy)

This method, as it seems was pretty weak from the begining. There's a step-by-step approach to cracking it here

Hmmm ... try kismet and airsnort ... I rest my case ;)

With these two gone, The Other alternatives AFAIK would be to;

1. Hide the SSID
2. Disable DHCP and assign static non-routable IPs
3. Use WPA instead of WEP

I found a good intro here, while googling, which gives a step by step guide to configure your router for security.
