1.Enable WPA encryption on D-Link DIR-450/DIR-451

WPA is a strong form of wireless encryption, however not all wireless adapters support this feature. If your wireless adapter does not support WPA you will want to use WEP to secure your wireless network.

Step 1: Open a web browser and type the IP address of the D-Link DIR-450/451 router into the address bar (default is http://192.168.0.1).

Step 2: The default username is admin (all lower case) and the default password is blank (nothing). Click on OK.

Step 3: Click on the Setup tab at the top and then click on Wireless Settings on the left-hand side.

Step 4: Select the type of WPA encryption you would like to use with your wireless adapter from the Security Mode drop down menu. For WPA-PSK select Enable WPA- Personal Wireless Security (enhanced).

Note: All wireless products on the wireless network must have the same level of security to connect to the network.

Step 5: In the WPA Personal section, configure the following:

Select the Cipher Type

TKIP (Temporal Key Integrity Protocol) provides per-packet key generation and is based on WEP.
AES (Advanced Encryption Standard) is a very secure block based encryption.

Select the PSK or EAP

When PSK is selected, your wireless clients will need to provide a Passphrase for authentication.
When EAP is selected, you will need to have a RADIUS server on your network which will handle the authentication of all your wireless clients.

Enter your Passphrase

The key can contain up to 63 alphanumeric characters (any letters or numbers). It cannot be shorter than eight characters, although for proper security it needs to be of ample length and should not be a commonly known phrase.

Re-Enter your Passphrase
Step 6: Click the Save Settings button to save your settings.

2.Enable WEP encryption on D-Link DIR-450/DIR-451

Note: Enabling WEP on a DRAFT N connection will cap the speed to 54mbps. To gain the Draft N possible speeds, WPA2 is recomended. However WPA will also work.

Step 1: Open a web browser and type the IP address of the DIR series router into the address bar (default is http://192.168.0.1).

Step 2: The default username is admin (all lower case) and the default password is blank (nothing). Click on OK.

Step 3: Click on the Setup tab at the top and then click on Wireless Settings on the lefthand side.

Step 4: From the Wireless Security Mode dropdown menu, select WEP encryption. WEP is the wireless encryption standard. To use it you must enter the same key(s) into the router and all wireless clients you wish to connect.

For 64 bit keys you must enter 10 hex digits into each key box. For 128 bit keys you must enter 26 hex digits into each key box. A hex digit is either a number from 0 to 9 or a letter from A to F.

You may also enter any text string into a WEP key box, in which case it will be converted into a hexadecimal key using the ASCII values of the characters. A maximum of 5 text characters can be entered for 64 bit keys, and a maximum of 13 characters for 128 bit keys.

Step 5: Click on Save Settings to save your settings.
