Changing the Wireless Security Settings
Your Router is equipped with WPA/WPA2 (Wi-Fi Protected Access), the
latest wireless security standard. It also supports the legacy security
standard, WEP (Wired Equivalent Privacy). By default, wireless
security is disabled. To enable security, you must first determine
which standard you want to use. To access the security settings, click
"Security" on the Wireless tab.
