Section 4 - Wireless Security
Wireless Security
This section will show you the different levels of security you can use to protect your data from intruders. The
DWA-126 offers the following types of security:
• WPA2 (Wi-Fi Protected Access 2) 		
• WPA (Wi-Fi Protected Access)			
• WPA2-PSK (Pre-Shared Key)
• WPA-PSK (Pre-Shared Key)
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 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 WPA/WPA2 Passphrase
Using the D-Link Wireless Connection Manager
It is recommended to enable WPA-PSK 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 WPA-PSK passphrase being used.
1. Open the Wireless Connection Manager by double-clicking on
the D-Link icon on your desktop.
2. Highlight the wireless network (SSID) you would like to connect
to and click Connect. If the network is using WPA-PSK, the
screen (as shown to the bottom-right) will appear.
3. Enter the WPA-PSK passphrase exactly as it is on your
wireless router or access point. Click the Show text in the
password field box to see the passphrase. Unchecking it will
hide it.
4. Click OK to connect to the network. Allow up to 30 seconds
to connect.
If you would like to create a new network and enter the WPA-PSK
settings, refer to the next page.

Configure WPA/WPA2 (RADIUS)
Using the D-Link Wireless Connection Manager
WPA and WPA2 are for advanced users who are familiar with using a RADIUS server and setting up certificates.
1. Open the Wireless Connection Manager by double-clicking on the D-Link
icon on your desktop. Click on New to create a new profile or highlight an
existing profile and click Modify.
2. Select WPA/WPA2-Enterprise under Set Security Option and then select
TKIP or AES.
3. Click on Advanced Config to continue.
4. Next to EAP Type, select EAP-TLS, EAP-TTLS, or PEAP. Extensible
Authentication Protocols allow devices on the network to request
authentication from the RADIUS server in the network. All the devices
on the network must use the same EAP type when using a RADIUS
server for authentication. Some RADIUS servers require that the Validate
Server field be selected. Check this field if your RADIUS server requires
validation.
5. Select an User Certificate from the drop-down menu.
6. Enter the login information required to authenticate.
7. Click Add to enter the IP address(es) of your RADIUS servers.
8. Click OK to save your settings.

2. The computer does not recognize the DWA-126 Wireless USB Adapter.
Make sure that the DWA-126 Wireless USB Adapter is properly seated in the computer’s USB port.
If Windows does not detect the hardware upon insertion of the adapter, make sure to completely remove drivers that
were previously loaded.
3. The computer with the DWA-126 installed is unable to connect to the wireless network and/or the Internet.
• Check that the LED indicators for the broadband modem are indicating normal activity. If not, there may
be a problem with the broadband connection.
• Check that the LED indicators on the wireless router are functioning properly. If not, check that the AC
power and Ethernet cables are firmly connected.
• Check that the IP Address, subnet mask, gateway, and DNS settings are correctly entered for the
network
• In Infrastructure mode, make sure the same Service Set Identifier (SSID) is specified on the settings
for the wireless clients and access points. The SSID factory default setting for D-Link products is default.
(Double-click on the WLAN icon in the taskbar. The Link Info screen will display the SSID setting.)
