Configure Wireless Settings Section Field Description WPA Security for Personal Networks - WPA or WPA2 Personal Modes Wi-Fi Protected Access (WPA) is a more secure wireless technology than WEP. WPA can be used for both Enterprise (corporate applications) and Personal (home network) wireless networks. We strongly recommend that you select either WPA-Personal or WPA2-Personal as the security mode for your home network, depending on which mode is supported by the wireless adapter in your PC or wireless clients. WPA-Personal (aka WPA-PSK or WPA-Pre-Shared Key), provides a more secure wireless network that WEP. WPA-Personal introduces TKIP user authentication and stronger encryption keys than WEP. WPA2-Personal (aka WPA2-PSK or WPA2-Pre-Shared Key) provides the most secure standards-based wireless networking. WPA2-Personal incorporates AES (Advanced Encryption Standard) for data transmission. Note: Not all wireless adapters support WPA2. WPA is supported across a wider range of devices. Whether you use WPA or WPA2, make sure to use a "strong" passphrase. A strong passphrase is a string of random characters at least 21 characters in length. Select from one of the following three WPA or WPA2 Personal modes: ƒ WPA-Personal ƒ WPA2-Personal ƒ WPA or WPA2-Personal Field Descriptions ƒ Encryption. The default is TKIP+AES. ƒ Pre-Shared Key. Enter a key of 8 to 63 characters. ƒ Key Renewal. Enter a Key Renewal period, which instructs the device how often it should change encryption keys. The default is 3600 seconds. 4021196 Rev A 41
