Section 4 - Security

Wireless Security

This section will show you the different levels of security you can use to protect your data from intruders. The DIR-300 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 dened 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 dened so that you can change keys easily.

Section 4 - Security

Congure 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 conguration by opening a web browser and entering the IP address of the router (192.168.0.1).

Click on Wireless Setup on the left side.

2. Next to Security Mode, select Enable WEP Wireless Security (basic).

3. Next to Authentication, select either Shared Key or Open.

Shared Key is recommended as it provides greater security

when WEP is enabled.

4. Select either 64Bit or 128Bit encryption from the drop-down

menu next to WEP Encryption.

5. Next to Default Key Type, select WEP Key 1 and enter a WEP

key that you create. Make sure you enter this key exactly on

all your wireless devices. You may enter up to four different keys either using Hex or ASCII. Hex is recommended (letters A-F and numbers 0-9 are valid). In ASCII all numbers and letters are valid.

6. Click Save Settings to save your settings. If you are conguring 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 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-specic 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.

Congure WPA/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.

1. Log into the web-based conguration by opening a web browser and entering the IP address of the router (192.168.0.1). Click on

Wireless Setup on the left side.

2. Next to Security Mode, select Enable WPA/WPA2 Wireless

Security (enhanced).

3. Next to Cipher Mode, select TKIP, AES, or Auto.

4. Next to PSK/EAP, select PSK.

5. Next to Network Key, 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. Click Save Settings to save your settings. If you are conguring the Router with a wireless adapter, you will lose connectivity until you enable WPA/WPA2-PSK on your adapter and enter the same passphrase as you did on the

Router.

Section 6 - Setting Up Wi-Fi Protection (WCN 2.0 in Windows Vista)

Setting Up Wi-Fi Protection

(WCN 2.0 in Windows Vista)

The DIR-300 supports Wi-Fi protection, referred to as WCN 2.0 in Windows Vista. The instructions for setting this up depend on whether you are using Windows Vista to congure the Router or third party software.

Initial Router Conguration for Wi-Fi Protection

When you rst set up the Router, Wi-Fi protection is disabled and uncongured. To enjoy the benets of Wi-Fi protection, the Router must be both enabled and congured. There are three basic methods to accomplish this: use Windows Vista’s built-in support for WCN 2.0, use software provided by a third party, or use the traditional Ethernet approach.

If you are running Windows Vista, tick the Enable checkbox on the Wireless Network window. Use the Current PIN

that is displayed on the Wireless Network window or choose to click the Generate New PIN button or Reset PIN to Default button.

If you are using third party software to set up Wi-Fi Protection, carefully follow the directions. When you are nished, proceed to the next section to set up the newly-congured Router.

Section 6 - Setting Up Wi-Fi Protection (WCN 2.0 in Windows Vista)

Setting Up a Congured Router

Once the Router has been congured, you can use the push button on the Router or third party software to invite a newcomer to join your Wi-Fi protected network. For maximum security, the software method is recommended. However,

the push button method is ideal if there is no access to a GUI.

If you are using the Router’s Wi-Fi Security push button option, simultaneously depress the push button located on the side of the Router and the button on the client (or virtual button on the client’s GUI). Next click Finish. The Client’s software will then allow a newcomer to join your secure, Wi-Fi protected network.

If you are using third party software, run the appropriate Wi-Fi Protected System utility. You will be asked to either use

the push button method or to manually enter the PIN. Follow the on-screen instructions.
