Simple.  Signal strength from at least three access points will pinpoint
your location.  If any of the AP's have known GPS coordinates, your
location can be interpolated.

To fix this, change your MAC address (or whatever WiFi uses for that),
randomly every time you move around, and don't share things that can
identify your machine.  i.e don't run things such as SMTP, FTP, Microsoft
File sharing which give away your host name, and don't accept cookies from
web sites that can track you, and make sure your browser doesn't leak your
email address, and be aware that anything you do can be sniffed.
