Connect a Wireless Network Using Windows 7 on D-Link DI-604 Router.

It is recommended to enable wireless security (WPA/WPA2) on your wireless router or access point before configuring your wireless adapter. If you are joining an existing network, you will need to know the security key or passphrase being used.

1. Click on the wireless icon in your system tray (lower-right corner).

2. The utility will display any available wireless networks in your area.

3. Highlight the wireless network (SSID) you would like to connect to and click the Connect button.
If you get a good signal but cannot access the Internet, check your TCP/IP settings for your wireless adapter. Refer to the Networking Basics section in this manual for more information.

4. The following window appears while your computer tries to connect to the router.

5.Enter the same security key or passphrase that is on your router and click Ok.It may take 20-30 seconds to connect to the wireless network. If the connection fails, please verify that the security settings are correct. The key or passphrase
must be exactly the same as on the wireless router.

WPA is a more powerful security technology for Wi-Fi networks than WEP. It provides strong data protection by using encryption as well as strong access controls and user authentication. WPA utilizes 128-bit encryption keys and dynamic session keys to ensure your wireless network’s privacy and enterprise security.

There are two basic forms of WPA:

• WPA Enterprise (requires a Radius server)
• WPA Personal (also known as WPA-PSK)

Either can use TKIP or AES for encryption. Not all WPA hardware supports AES.

WPA-PSK is basically an authentication mechanism in which users provide some form of credentials to verify that they should be allowed access to a network. This requires a single password entered into each WLAN node (Access Points, Wireless Routers, client adapters, bridges). As long as the passwords match, a client will be granted access to a WLAN.

Encryption mechanisms used for WPA and WPA-PSK are the same. The only difference between the two is in WPA-PSK, authentication is reduced to a simple common password, instead of user-specific credentials.

The Pre-Shared Key (PSK) mode of WPA is considered vulnerable to the same risks as any other shared password system – dictionary attacks for example. Another issue may be key management difficulties such as removing a user once access has been granted where the key is shared among multiple users, not likely in a home environment.

The PSP (PlayStation® Portable) only supports WPA, not WPA2. If you are using WPA/Auto, you may need to lock the router to WPA only (firmware 1.07 or higher). This will allow you to connect to your PSP. To switch to WPA only, follow these steps:

Step 1: Open a web browser and type the IP address of the DIR series(D-Link DIR-655) 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 WPA-Personal.

Step 5: From the WPA dropdown menu, select WPA Only.

Step 6: Under Pre-shared Key, enter the desired Pre-Shared Key.

Step 7: Click on Save Settings to save your settings.

Step 4: From the Wireless Security Mode dropdown menu, select WPA-Personal encryption.

Step 5: From the WPA Mode dropdown, Under WPA, select the form of WPA you would like to use.

Use WPA or WPA2 mode to achieve a balance of strong security and best compatibility. This mode uses WPA for legacy clients while maintaining higher security with stations that are WPA2 capable. Also the strongest cipher that the client supports will be used.

For best security, use WPA2 Only mode. This mode uses AES(CCMP) cipher and legacy stations are not allowed access with WPA security.

For maximum compatibility, use WPA Only. This mode uses TKIP cipher. Some gaming and legacy devices work only in this mode. To achieve better wireless performance use WPA2 Only security mode (or in other words AES cipher).

Step 6: In the Pre-Shared Key box, enter the desired Pre-shared key.

This is the “password” that allows communication between you’re encrypted client (e.g. the PSP or your wireless computer) and the encrypted wireless signal coming from the router. This password must contain at least 8 characters, the characters can be anything you can create from your keyboard.

Step 7: Click on Save Settings to save your settings.

WEP

WEP stands for Wired Equivalent Privacy. It is based on the IEEE 802.11 standard and uses the RC4 encryption algorithm. Enabling WEP allows you to increase security by encrypting data being transferred over your wireless network.

When WEP encryption is enabled, there are up to four options*: 64-bit and 128-bit. 64-bit is the same as 40-bit WEP. The lower level of WEP encryption uses a 40-bit (10 character) “secret key” (set by the user), and a 24-bit “initialization vector” (not under user control). So lower level 40 and 64 bit WEP cards are equivalent in encryption strength and compatibility.

* 802.11B supports 64 and 128-bit encryption, 802.11B+ (enhanced) supports 64, 128, and 256-bit encryption, 802.11G support 64 and 128-bit, and 802.11A supports 64, 128, and 152-bit encryption.

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 technology is designed to work with existing Wi-Fi products that have been enabled with WEP (i.e., as a software/firmware upgrade to existing hardware).
