Troubleshooting
This chapter provides solutions to problems that can occur during the installation and operation of the DIR-850L. Read the
following descriptions if you are having problems. The examples below are illustrated in Windows® XP. If you have a dierent
operating system, the screenshots on your computer will look similar to the following examples.
1. Why can’t I access the web-based conguration utility?
When entering the IP address of the D-Link router (192.168.0.1 for example), you are not connecting to a website nor do you
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:
- Microsoft Internet Explorer® 7 and higher
- Mozilla Firefox 3.5 and higher
- Google™ Chrome 8 and higher
- Apple Safari 4 and 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
dierent cable or connect to a dierent port on the device if possible. If the computer is turned o, the link light may not be
on.
Disable any Internet security software running on the computer. Software rewalls such as Zone Alarm, Black Ice, Sygate,
Norton Personal Firewall, and Windows® XP rewall may block access to the conguration pages. Check the help les included
with your rewall software for more information on disabling or conguring it.

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 web management.
If you still cannot access the conguration, unplug the power to the router for 10 seconds and plug back in. Wait about 30
seconds and try accessing the conguration. If you have multiple computers, try connecting using a dierent 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

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).
To nd the proper MTU Size, you’ll have to do a special ping of the destination youre trying to go to. A destination could be
another computer, or a URL.
Click on Start and then click Run.
Window95, 98, and Me users type in command (Windows® NT, 2000, XP, Vista®, and 7 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

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 were working with (1452+28=1480).
Once you nd your MTU, you can now congure 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 conguration page
for the device.
Click on Setup and then click Manual Congure.
To change the MTU enter the number in the MTU eld 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 oce environments, and public areas such as airports, coee shops
and universities. Innovative ways to utilize WLAN technology are helping people to work and communicate more eciently.
Increased mobility and the absence of cabling and other xed infrastructure have proven to be benecial 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 oce 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 aord. 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 dierent 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.

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 its for home, oce, business,
D-Link has a wireless solution for it.
Home
• Gives everyone at home broadband access
• Surf the web, check email, instant message, etc.
• Gets rid of the cables around the house
• Simple and easy to use
Small Oce and Home Oce
• Stay on top of everything at home as you would at oce
• Remotely access your oce network from home
• Share Internet connection and printer with multiple computers
• No need to dedicate oce space

Where is wireless used?
Wireless technology is expanding everywhere not just at home or oce. People like the freedom of mobility and its 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, Coee Shops, Libraries, Restaurants, and Convention Centers.
Wireless network is easy to setup, but if you’re installing it for the rst 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 signicantly reduce any interference that the appliances might cause since they operate on same frequency.
Security
146D-Link DIR-850L User Manual
Appendix A - Wireless Basics
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-850L 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® 7/Vista® users type cmd in the Start Search box.)
At the prompt, type ipcong 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 rewall software programs may block a DHCP
request on newly installed adapters.

Step 4
Click Use the following IP address and enter an IP address that is on the same subnet
as your network or the LAN IP address on your router.
Example: If the router´s LAN IP address is 192.168.0.1, make your IP address 192.168.0.X
where X is a number between 2 and 99. Make sure that the number you choose is not
in use on the network. Set the Default Gateway the same as the LAN IP address of your
router (I.E. 192.168.0.1).
Set Primary DNS the same as the LAN IP address of your router (192.168.0.1). The
Secondary DNS is not needed or you may enter a DNS server from your ISP.
