Seem like no one turns on the security features for wireless. If I were a thief, I would never need to pay for my internet again.

Just google "Linksys" and "security", you'll find instructions with screen shots. And yes, it is easy to setup.

I use 128 bit WEP passphrase and MAC Filtering. The MAC filter limits what computers can talk to the router. Each computer's network interface has a unique serial number and if that number is not configured in the router then the router won't accept a connection. Also, change the router's administor password.
