Don't assume your wireless home network is safe because you have initially configured your security settings.

The first step in improving your data security is to change your router password. The default router passwords are well-known and are less effective than a unique password that you define.

The most important step to improve your data security is to upgrade to WPA2 or WPA security.

If the devices connected to your network aren't compatible with WPA2 or WPA security, you can improve the protection provided by WEP encryption if you change your SSID and WEP encryption key periodically during the year.
