How to Configure WPA-PSK Encryption Security
Wi-Fi Protected Access (WPA) is wireless security with far greater protection than WEP.
WPA-PSK (pre-shared key) uses encryption of a shared key as the starting point. WPA has a
significant advantages over WEP — an encryption key differing in every packet. It is extremely
difficult for hackers to read messages even if they have intercepted the data.
To configure WPA-PSK security, click the Advanced Security button. The Advanced Security
button is located in the Settings page, Security section.

The Passphrase can be between 8 and 63 characters. Select TKIP or AES for the security
mechanism.
TKIP stands for Temporal Key Integrity Protocol. TKIP replaces WEP with a new encryption
algorithm that is stronger than the WEP algorithm, but that uses the calculation facilities present
on existing wireless devices to perform encryption operations.
One of the encryption methods supported by WPA, besides TKIP, is the Advanced Encryption
Standard (AES). This is viewed as the optimal choice for security conscience organizations, but
the problem with AES is that it requires a fundamental redesign of the NIC's hardware in both the
station and the access point. TKIP is a pragmatic compromise that allows organizations to deploy
better security while AES capable equipment is being designed, manufactured, and incrementally
deployed.
