How can I do this to a Linksys router? I'd like a password so others in my neighborhood can't hack into it because it's an open connection.

It varies between models. Reading the manual is a good place to start. The printed quick start guides you usually get are crap, you can find a better one on the CD or on LinkSys' site.

You can password-protect access to the router by turning such a function (WEP & WPA in its various forms) on in the router's control panel.
You you want to actually encrypt (which refers to the signal itself), you'll need a router/AP and wireless adapter that support an encryption sceheme of some kind (AES, 3DES, or whatever else). Use of these will kill performance (both transfers and CPU), with the possible exception of public key schemes. But public keys likely won't be available on that level; they're maintained by (hopefully) neutral third parties.

I'm assuming he wants to encrypt his wireless access.
To do so, you'll have to log into your router. This can be done by opening up a web browser (IE is fine) and typing your routers IP into the navigation bar (Usually 192.168.0.1). You will probably be prompted for a user name and password to actually get into the router. You'll have to look at the user manual for that, but you can try "Admin", with no password, which is the default for D-Link routers.
Once you're in, just look for the appropriate section on your router to enable a WEP or similar key configuration.
However, I do recommend connecting to your router via hardwire (ie - connect your PC to it with an ethernet cable), this will prevent any problems when it comes to applying the password, as you may be booted off your wireless network temporarily and this will cause your session to time out. It's just frustrating.
