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.

Configure WPA-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 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 WPA-Personal Security 
or Enable WPA2-Personal Security.
3. Next to Cipher Mode, select TKIP, AES, or Auto.
4. Next to PSK/EAP, select PSK.
5.  Next  to 
Passphrase,  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. Enter the passphrase again next to Confirmed Passphrase.
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 WPA-PSK (or WPA2-PSK) on your adapter and enter the same passphrase as you did 
on the router.

Connect to a Wireless Network
Using Windows® XP
Windows® XP users may use the built-in wireless utility (Zero Configuration Utility). The following instructions are for 
Service Pack 2 users. If you are using another company’s utility or Windows® 2000, please refer to the user manual of 
your wireless adapter for help with connecting to a wireless network. Most utilities will have a “site survey” option similar 
to the Windows® XP utility as seen below.
Right-click on the wireless computer icon in your system tray 
(lower-right  corner  next  to  the  time).  Select View  Available 
Wireless Networks.
If you receive the Wireless Networks Detected bubble, click 
on the center of the bubble to access the utility.
         or
The  utility  will  display  any  available  wireless  networks  in  your 
area.  Click  on  a  network  (displayed  using  the  SSID)  and  click 
the Connect button.
If you get a good signal but cannot access the Internet, check you 
TCP/IP settings for your wireless adapter. Refer to the Networking 
Basics section in this manual for more information.

Configure WEP
It is recommended to enable WEP 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 WEP key being used.
2. Highlight the wireless network (SSID) you would like to 
connect to and click Connect.
1. Open  the  Windows®  XP  Wireless  Utility  by  right-clicking 
on  the  wireless  computer  icon  in  your  system  tray

3. The Wireless Network Connection box will appear. Enter the same 
WEP key that is on your router and click Connect.
It may take 20-30 seconds to connect to the wireless network. If the 
connection fails, please verify that the WEP settings are correct. The 
WEP key must be exactly the same as on the wireless router.

Troubleshooting
This chapter provides solutions to problems that can occur during the installation and operation of the DIR-301.  Read 
the following descriptions if you are having problems.  (The examples below are illustrated in Windows® XP.  If you have 
a different operating system, the screenshots on your computer will look similar to the following examples.)
1. Why can’t I access the web-based configuration utility?
When entering the IP address of the D-Link router (192.168.0.1 for example), you are not connecting to a website on 
the Internet or have to be connected to the Internet. The device has the utility built-in to a ROM chip in the device itself. 
Your computer must be on the same IP subnet to connect to the web-based utility. 
• Make sure you have an updated Java-enabled web browser. We recommend the following: 
• Internet Explorer 6.0 or higher 
• Firefox 1.5 or higher 
• Verify physical connectivity by checking for solid link lights on the device. If you do not get a solid link light, try using 
a different cable or connect to a different port on the device if possible. If the computer is turned off, the link light may 
not be on.
• Disable any internet security software running on the computer. Software firewalls such as Zone Alarm, Black Ice, 
Sygate, Norton Personal Firewall, and Windows® XP firewall may block access to the configuration pages. Check the 
help files included with your firewall software for more information on disabling or configuring it.

• Configure your Internet settings:
• Go to Start > Settings > Control Panel. Double-click the Internet Options Icon. From the Security tab, 
click the button to restore the settings to their defaults.
• Click the Connection tab and set the dial-up option to Never Dial a Connection. Click the LAN Settings 
button. Make sure nothing is checked. Click OK. 
• Go to the Advanced tab and click the button to restore these settings to their defaults. Click OK three 
times.
• Close your web browser (if open) and open it.
• Access the web management. Open your web browser and enter the IP address of your D-Link router in the address 
bar. This should open the login page for your the web management. 
•  If  you  still  cannot  access  the  configuration,  unplug  the  power  to  the  router  for  10  seconds  and  plug  back  in. Wait 
about 30 seconds and try accessing the configuration. If you have multiple computers, try connecting using a different 
computer.
2. What can I do if I forgot my password?
If you forgot your password, you must reset your router. Unfortunately this process will change all your settings back 
to the factory defaults.
To  reset  the  router,  locate  the  reset  button  (hole)  on  the  rear  panel  of  the  unit.  With  the  router  powered  on,  use  a 
paperclip to hold the button down for 10 seconds. Release the button and the router will go through its reboot process. 
Wait about 30 seconds to access the router. The default IP address is 192.168.0.1. When logging in, the username is 
admin and leave the password box empty.
