What is WPA?

WPA, or Wi-Fi Protected Access, is a Wi-Fi standard that was designed to improve the security features of WEP (Wired Equivalent

Privacy).

The two major improvements over WEP:

• Improved data encryption through the Temporal Key Integrity Protocol (TKIP). TKIP scrambles the keys using a

hashing algorithm and, by adding an integrity-checking feature, ensures that the keys haven’t been tampered with.

WPA2 is based on 802.11i and uses Advanced Encryption Standard (AES) instead of TKIP.

• User authentication, which is generally missing in WEP, through the extensible authentication protocol (EAP). WEP

regulates access to a wireless network based on a computer’s hardware-specific MAC address, which is relatively

simple to be sniffed out and stolen. EAP is built on a more secure public-key encryption system to ensure that only

authorized network users can access the network.

WPA-PSK/WPA2-PSK uses a passphrase or key to authenticate your wireless connection. The key is an alpha-numeric password

between 8 and 63 characters long. The password can include symbols (!?*&_) and spaces. This key must be the exact same key

entered on your wireless router or access point.

WPA/WPA2 incorporates user authentication through the Extensible Authentication Protocol (EAP). EAP is built on a more secure

public key encryption system to ensure that only authorized network users can access the network.

Configure WPA-PSK and WPA2-PSK

It is recommended to enable encryption on your wireless Router before your wireless network adapters. Please establish

wireless connectivity before enabling encryption. Your wireless signal may degrade when enabling encryption due to the added

overhead.
