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 2 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

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.

1.

Log into the web-based configuration by

opening a web browser and entering the IP

address of the router (192.168.0.1).

Click

on

Wireless Settings

on the left side.

2. Next to

Security Mode

, select

Enable

WPA-Personal Security

or

Enable WPA2-

Personal Security

.

3. Next to

Cipher Mode

, select

TKIP, AES,

or

Auto

.

4. Next to

PSK/EAP

, select

PSK

.

5. Next to

Passphrase

, enter a key (passphrase). The key is an alpha-numeric password between 8 and 63 characters

long. The password can include symbols (!?*&_) and spaces. Make sure you enter this key exactly the same on all

other wireless clients.

6. Enter the passphrase again next to

Confirmed Passphrase

.

7. Click

Save Settings

to save your settings. If you are configuring the router with a wireless adapter, you will lose

connectivity until you enable WPA-PSK (or WPA2-PSK) on your adapter and enter the same passphrase as you did

on the router.
