Troubleshooting
This chapter provides solutions to problems that can occur during the installation and operation of the DIR-855.  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 
• Netscape 8 or higher 
• Mozilla 1.7.12 (5.0) or higher 
• Opera 8.5 or higher 
• Safari 1.2 or higher (with Java 1.3.1 or higher) 
• Camino 0.8.4 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.

Section 6 - Troubleshooting
• 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.

Section 6 - Troubleshooting
3. Why can’t I connect to certain sites or send and receive emails when connecting through my router? 
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). 
Note: AOL DSL+ users must use MTU of 1400. 
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. 
• Click on Start and then click Run. 
• Windows® 95, 98, and Me users type in command (Windows® NT, 2000, and XP users type in cmd) and 
press Enter (or click OK). 
• Once the window opens, you’ll need to do a special ping. Use the following syntax: 
  ping [url] [-f] [-l] [MTU value] 
Example: ping yahoo.com -f -l 1472 

84D-Link DIR-855 User Manual
Section 6 - Troubleshooting
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). 
Once you find your MTU, you can now configure your router with the proper MTU size. 
To change the MTU rate on your router follow the steps below: 
• Open your browser, enter the IP address of your router (192.168.0.1) and click OK. 
• Enter your username (admin) and password (blank by default). Click OK to enter the web configuration 
page for the device. 
• Click on Setup and then click Manual Configure.  
• To change the MTU enter the number in the MTU field and click Save Settings to save your settings. 
• Test  your  email.  If  changing  the  MTU  does  not  resolve  the  problem,  continue  changing  the  MTU  in 
increments of ten.

Appendix A - Wireless Basics
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.
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. 
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. 
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.

What is 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.
Why D-Link Wireless? 
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.
How does wireless work? 
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).
Wireless Local Area Network (WLAN)
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.

87D-Link DIR-855 User Manual
Appendix A - Wireless Basics
Wireless Personal Area Network (WPAN)
Bluetooth is the industry standard wireless technology used for WPAN. Bluetooth devices in WPAN operate in a range 
up to 30 feet away.
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.
Who uses 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.
Home
  • Gives everyone at home broadband access
  • Surf the web, check email, instant message, and etc
  • Gets rid of the cables around the house
  • Simple and easy to use
Small Office and Home Office
  • Stay on top of everything at home as you would at office
  • Remotely access your office network from home
  • Share Internet connection and printer with multiple computers
  • No need to dedicate office space

Appendix A - Wireless Basics
Where is wireless used? 
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”.
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 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.
Tips
Here are a few things to keep in mind, when you install a wireless network.
Centralize your router or Access Point
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.
Eliminate Interference 
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.

Appendix A - Wireless Basics
Security 
Don’t let you next-door neighbors or intruders connect to your wireless network. Secure your wireless network by turning 
on the WPA or WEP security feature on the router. Refer to product manual for detail information on how to set it up.
There are basically two modes of networking: 
• Infrastructure – All wireless clients will connect to an access point or wireless router.
• 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.
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. 
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.

Check your IP address
After you install your new D-Link adapter, by default, the TCP/IP settings should be set to obtain an IP address from a 
DHCP server (i.e. wireless router) automatically. To verify your IP address, please follow the steps below.
Click on Start > Run. In the run box type cmd and click OK. (Windows® Vista™ users type cmd in the Start Search 
box.)
At the prompt, type ipconfig and press Enter.
This will display the IP address, subnet mask, and 
the default gateway of your adapter.
If  the  address  is  0.0.0.0,  check  your  adapter 
installation,  security  settings,  and  the  settings 
on your router. Some firewall software programs 
may  block  a  DHCP  request  on  newly  installed 
adapters.
