Wireless Security

This section will show you the different levels of security you can use to protect your data from intruders. The

DWR-113 offers the following types of security:

• WPA2 (Wi-Fi Protected Access 2)

• WPA2-PSK (Pre-Shared Key)

• WPA (Wi-Fi Protected Access)

• WPA-PSK (Pre-Shared Key)

• WEP (Wired Equivalent Privacy)

What is WEP?

WEP stands for Wired Equivalent Privacy. It is based on the IEEE 802.11 standard and uses the RC4 encryption algorithm. WEP provides

security by encrypting data over your wireless network so that it is protected as it is transmitted from one wireless device to another.

To gain access to a WEP network, you must know the key. The key is a string of characters that you create. When using WEP, you must

determine the level of encryption. The type of encryption determines the key length. 128-bit encryption requires a longer key than 64-bit

encryption. Keys are defined by entering in a string in HEX (hexadecimal - using characters 0-9, A-F) or ASCII (American Standard Code for

Information Interchange – alphanumeric characters) format. ASCII format is provided so you can enter a string that is easier to remember.

The ASCII string is converted to HEX for use over the network. Four keys can be defined so that you can change keys easily.

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

Wireless Settings

on the left side.

2. Next to

Security Mode

, select

Enable

WEP Security

.

3. Next to

Authentication

, select

Open

or

Shared Key

.

4. Select either

64-bit

or

128-bit

encryption from the drop-down box next

to

WEP Encryption

.

5. Next to

Key Type

, select either

Hex

or

ASCII

.

Hex (recommended) - Letters A-F and numbers 0-9 are valid.

ASCII - All numbers and letters are valid.

6. Next to

Key 1

, enter a WEP key that you create. Make sure you enter

this key exactly on all your wireless devices. You may enter up to 4

different keys.

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 WEP on your adapter and enter the same WEP key as you did on the router.

Section 4 - Security

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.
