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-685 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)
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 have not 
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 acces\
s 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 (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 
Setup and then click  Wireless Setup on the left side.
2.  Click the Manual Wireless Connection Setup button.
3. Next to Security Mode, select Enable WPA/WPA2 Wireless         
Security (enhanced).
4.  Next to Cypher Type, select TKIP, AES, or Both.
5. Next to PSK / EAP select PSK from the drop-down menu. 
6.  Next  to  Network  Key,  enter  a  key  (passphrase).  The  key  is 
entered  as  a  pass-phrase  in  ASCII  format  at  both  ends  of  the 
wireless  connection.  The  pass-phrase  must  be  between  8  and 
63 characters. 
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 on your adapter and enter the same passphrase as you did on the router.

Connect to a Wireless Network
Using Windows Vista® 
Windows Vista® users may use the built-in wireless utility. 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 Vista
® utility as seen below.
Right-click on the wireless computer icon in your system tray 
(lower-right  corner  next  to  the  time).  Select  Connect  to  a 
network.
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  the  TCP/IP  settings  for  your  wireless  adapter.  Refer 
to  the Networking  Basics  section  in  this  manual  for  more 
information.
