WISH Settings
D-Link DIR-855 User Manual
49
WISH supports overlaps between rules. If more than one rule matches for a specific message flow, the rule with the highest
priority will be used.
WISH Rules: A WISH Rule identifies a specific message flow and assigns a priority to that flow. For most applications, the priority classifiers
ensure the right priorities and specific WISH Rules are not required.
Automatic: When enabled, this option causes the router
to automatically attempt to prioritize traffic
streams that it doesn’t otherwise recognize,
based on the behaviour that the streams
exhibit. This acts to deprioritize streams that
exhibit bulk transfer characteristics, such as
file transfers, while leaving interactive traffic,
such as gaming or VoIP, running at a normal
priority.
Windows Media Enables the router to recognize certain audio
Center: and video streams generated by a Windows
Media Center PC and to prioritize these above
other traffic. Such streams are used by systems
known as Windows Media Extenders, such as
the Xbox 360.
HTTP: Allows the router to recognize HTTP transfers
for many common audio and video streams
and prioritize them above other traffic. Such
streams are frequently used by digital media
players.
Enable WISH: Enable this option if you want to allow WISH
to prioritize your traffic.
WISH is short for Wireless Intelligent Stream Handling, a technology developed to enhance your experience of using
a wireless network by prioritizing the traffic of different applications.

What is WPA?
• WPA2-PSK (Pre-Shared Key)
• WPA-PSK (Pre-Shared Key)
D-Link DIR-855 User Manual
67
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.
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.
• 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.
• 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.
The 2 major improvements over WEP:
WPA, or Wi-Fi Protected Access, is a Wi-Fi standard that was designed to improve the security features of WEP (Wired
Equivalent Privacy).
• WPA2 (Wi-Fi Protected Access 2)
• WPA (Wi-Fi Protected Access)
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:

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.
If you forgot your password, you must reset your router. Unfortunately this process will change all your settings back
to the factory defaults.
2. What can I do if I forgot my password?
• 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.
• 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.
• Close your web browser (if open) and open it.
• Go to the Advanced tab and click the button to restore these settings to their defaults. Click OK three
times.
• 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 Start > Settings > Control Panel. Double-click the Internet Options Icon. From the Security tab,
click the button to restore the settings to their defaults.
• Configure your Internet settings:

Example: ping yahoo.com -f -l 1472
ping [url] [-f] [-l] [MTU value]
• Once the window opens, you’ll need to do a special ping. Use the following syntax:
• Windows® 95, 98, and Me users type in command (Windows® NT, 2000, and XP users type in cmd) and
press Enter (or click OK).
• Click on Start and then click Run.
83
To find the proper MTU Size, you’ll have to do a special ping of the destination you’re trying to go to. A destination could
be another computer, or a URL.
Note: AOL DSL+ users must use MTU of 1400.
If you are having a problem sending or receiving email, or connecting to secure sites such as eBay, banking sites, and
Hotmail, we suggest lowering the MTU in increments of ten (Ex. 1492, 1482, 1472, etc).
3. Why can’t I connect to certain sites or send and receive emails when connecting through my router?
Section 6 - Troubleshooting
D-Link DIR-855 User Manual
• Test your email. If changing the MTU does not resolve the problem, continue changing the MTU in
increments of ten.
• To change the MTU enter the number in the MTU field and click Save Settings to save your settings.
• Click on Setup and then click Manual Configure.
• Enter your username (admin) and password (blank by default). Click OK to enter the web configuration
page for the device.
• Open your browser, enter the IP address of your router (192.168.0.1) and click OK.
To change the MTU rate on your router follow the steps below:
Once you find your MTU, you can now configure your router with the proper MTU size.
84
You should start at 1472 and work your way down by 10 each time. Once you get a reply, go up by 2 until you get a
fragmented packet. Take that value and add 28 to the value to account for the various TCP/IP headers. For example,
lets say that 1452 was the proper value, the actual MTU size would be 1480, which is the optimum for the network
we’re working with (1452+28=1480).

D-Link DIR-855 User Manual
85
Under many circumstances, it may be desirable for mobile network devices to link to a conventional Ethernet LAN in
order to use servers, printers or an Internet connection supplied through the wired LAN. A Wireless Router is a device
used to provide this link.
Wireless users can use the same applications they use on a wired network. Wireless adapter cards used on laptop
and desktop systems support the same protocols as Ethernet adapter cards.
A wireless local area network (WLAN) is a cellular computer network that transmits and receives data with radio signals
instead of wires. Wireless LANs are used increasingly in both home and office environments, and public areas such
as airports, coffee shops and universities. Innovative ways to utilize WLAN technology are helping people to work and
communicate more efficiently. Increased mobility and the absence of cabling and other fixed infrastructure have proven
to be beneficial for many users.
D-Link wireless products are based on industry standards to provide easy-to-use and compatible high-speed wireless
connectivity within your home, business or public access wireless networks. Strictly adhering to the IEEE standard,
the D-Link wireless family of products will allow you to securely access the data you want, when and where you want
it. You will be able to enjoy the freedom that wireless networking delivers.
Appendix A - Wireless Basics
D-Link DIR-855 User Manual
86
In a wireless local area network, a device called an Access Point (AP) connects computers to the network. The access
point has a small antenna attached to it, which allows it to transmit data back and forth over radio signals. With an
indoor access point as seen in the picture, the signal can travel up to 300 feet. With an outdoor access point the signal
can reach out up to 30 miles to serve places like manufacturing plants, industrial locations, college and high school
campuses, airports, golf courses, and many other outdoor venues.
Wireless Local Area Network (WLAN)
Wireless works similar to how cordless phone work, through radio signals to transmit data from one point A to point
B. But wireless technology has restrictions as to how you can access the network. You must be within the wireless
network range area to be able to connect your computer. There are two different types of wireless networks Wireless
Local Area Network (WLAN), and Wireless Personal Area Network (WPAN).
How does wireless work?
D-Link is the worldwide leader and award winning designer, developer, and manufacturer of networking products.
D-Link delivers the performance you need at a price you can afford. D-Link has all the products you need to build your
network.
Why D-Link Wireless?
Wireless or Wi-Fi technology is another way of connecting your computer to the network without using wires. Wi-Fi
uses radio frequency to connect wirelessly, so you have the freedom to connect computers anywhere in your home or
office network.
What is Wireless?

Wireless technology as become so popular in recent years that almost everyone is using it, whether it’s for home, office,
business, D-Link has a wireless solution for it.
Who uses wireless?
Compared to WLAN the speed and wireless operation range are both less than WLAN, but in return it doesn’t use
nearly as much power which makes it ideal for personal devices, such as mobile phones, PDAs, headphones, laptops,
speakers, and other devices that operate on batteries.
Bluetooth is the industry standard wireless technology used for WPAN. Bluetooth devices in WPAN operate in a range
up to 30 feet away.

Place home appliances such as cordless telephones, microwaves, and televisions as far away as possible from the
router/access point. This would significantly reduce any interference that the appliances might cause since they operate
on same frequency.
Eliminate Interference
Make sure you place the router/access point in a centralized location within your network for the best performance. Try
to place the router/access point as high as possible in the room, so the signal gets dispersed throughout your home.
If you have a two-story home, you may need a repeater to boost the signal to extend the range.
Centralize your router or Access Point
Here are a few things to keep in mind, when you install a wireless network.
Tips
Wireless network is easy to setup, but if you’re installing it for the first time it could be quite a task not knowing where to
start. That’s why we’ve put together a few setup steps and tips to help you through the process of setting up a wireless
network.
Using a D-Link Cardbus Adapter with your laptop, you can access the hotspot to connect to Internet from remote
locations like: Airports, Hotels, Coffee Shops, Libraries, Restaurants, and Convention Centers.
Wireless technology is expanding everywhere not just at home or office. People like the freedom of mobility and it’s
becoming so popular that more and more public facilities now provide wireless access to attract people. The wireless
connection in public places is usually called “hotspots”.
Where is wireless used?
Appendix A - Wireless Basics
D-Link DIR-855 User Manual
89
An Ad-Hoc network contains only clients, such as laptops with wireless cardbus adapters. All the adapters must be in
Ad-Hoc mode to communicate.
An Infrastructure network contains an Access Point or wireless router. All the wireless devices, or clients, will connect
to the wireless router or access point.
• Ad-Hoc – Directly connecting to another computer, for peer-to-peer communication, using wireless network
adapters on each computer, such as two or more DIR-855 wireless network Cardbus adapters.
• Infrastructure – All wireless clients will connect to an access point or wireless router.
There are basically two modes of networking:
