Wireless Security
This section will show you the different levels of security you can use \
to protect your data from intruders. The 
DIR-855 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 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 user\
s can access the network.

Configure WPA-Personal (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 Settings on the left side.
2. Next to Security Mode, select WPA-Personal.
3. Next to WPA Mode, select Auto, WPA2 Only, or WPA Only. Use Auto 
if you have wireless clients using both WPA and WPA2.
4. Next to Cypher Type, select TKIP and AES, TKIP, or AES.
5. Next to Group Key Update Interval, enter the amount of time before the 
group key used for broadcast and multicast data is changed (3600 is 
default).
6. Next to Pre-Shared 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 8-63 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 you TCP/
IP  settings  for  your  wireless  adapter.  Refer  to  the Networking  Basics 
section in this manual for more information.
