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 WEP

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

Setup

and then click

on the left side.

2. Next to

Security Mode

, select

.

3. Next to

WEP Key Length

, select the level of ecryption (64

or 128-bit) and either

Hex

or

ASCII

.

Hex

- (recommended) Letters A-F and numbers 0-9

are valid.

ASCII

- All numbers and letters are valid.

4. Next to
