Section 2 - Installation
Before you Begin
Installation
This section will walk you through the installation process. Placement of the router is very important. Do not place the router
in an enclosed area such as a closet, cabinet, or in an attic or garage.
• Please congure the router with the computer that was last connected directly to your modem.
• You can only use the Ethernet port on your modem. If you were using the USB connection before using the router,
then you must turn o your modem, disconnect the USB cable and connect an Ethernet cable to the Internet port
on the router, and then turn the modem back on. In some cases, you may need to call your ISP to change connection
types (USB to Ethernet).
• If you have DSL and are connecting via PPPoE, make sure you disable or uninstall any PPPoE software such as WinPoET,
BroadJump, or EnterNet 300 from your computer or you will not be able to connect to the Internet.

Section 2 - Installation
Wireless Installation Considerations
The D-Link wireless router lets you access your network using a wireless connection from virtually anywhere within the
operating range of your wireless network. Keep in mind, however, that the number, thickness and location of walls, ceilings,
or other objects that the wireless signals must pass through, may limit the range. Typical ranges vary depending on the types
of materials and background RF (radio frequency) noise in your home or business. The key to maximizing wireless range is to
follow these basic guidelines:
1. Keep the number of walls and ceilings between the D-Link router and other network devices to a minimum -
each wall or ceiling can reduce your adapter’s range from 3-90 feet (1-30 meters.) Position your devices so that
the number of walls or ceilings is minimized.
2. Be aware of the direct line between network devices. A wall that is 1.5 feet thick (.5 meters), at a 45-degree angle
appears to be almost 3 feet (1 meter) thick. At a 2-degree angle it looks over 42 feet (14 meters) thick! Position
devices so that the signal will travel straight through a wall or ceiling (instead of at an angle) for better reception.
3. Building materials make a dierence. A solid metal door or aluminum studs may have a negative eect on range.
Try to position access points, wireless routers, and computers so that the signal passes through drywall or open
doorways. Materials and objects such as glass, steel, metal, walls with insulation, water (sh tanks), mirrors, le
cabinets, brick, and concrete will degrade your wireless signal.
4. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that generate RF
noise.
5. If you are using 2.4 GHz cordless phones or X-10 (wireless products such as ceiling fans, lights, and home security
systems), your wireless connection may degrade dramatically or drop completely. Make sure your 2.4 GHz phone
base is as far away from your wireless devices as possible. The base transmits a signal even if the phone in not
in use.

Section 2 - Installation
1. Turn o and unplug your cable or DSL broadband modem. This is required.
2. Position your router close to your modem and a computer. Place the router in an open area of your intended
work area for better wireless coverage.
3. Unplug the Ethernet cable from your modem (or existing router if upgrading) that is connected to your computer.

A maximum of eight devices can be assigned Medium priority.
If no devices are explicitly assigned a priority, they will all be treated with equal
priority. If some devices are not assigned a priority and others are, the unassigned
devices will be treated with the lowest priority.
To assign a priority level to a device, drag the device card from the All Devices list

Troubleshooting
This chapter provides solutions to problems that can occur during the installation and operation of the DIR-842. Read the
following descriptions if you are having problems. The examples below are illustrated in Windows® XP. If you have a dierent
operating system, the screenshots on your computer will look similar to the following examples.
1. Why can’t I access the web-based conguration 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® 9 and higher
- Mozilla Firefox 20 and higher
- Google™ Chrome 25 and higher
- Apple Safari 5.1 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
dierent cable or connect to a dierent 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 ZoneAlarm, BlackICE, Sygate,
Norton Personal Firewall, and Windows® XP rewall may block access to the conguration pages. Check the help les included
with your rewall software for more information on disabling or conguring it.
87D-Link DIR-842 User Manual

• Congure 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 web management.
• If you still cannot access the conguration, unplug the power to the router for 10 seconds and plug back in. Wait about 30
seconds and try accessing the conguration. If you have multiple computers, try connecting using a dierent 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.

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 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, 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
89D-Link DIR-842 User Manual
Section 5 - 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 nd your MTU, you can now congure 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 conguration page
for the device.
• Click on Setup and then click Manual Congure.
• 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.

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 oce environments, and public areas such as airports, coee shops
and universities. Innovative ways to utilize WLAN technology are helping people to work and communicate more eciently.
Increased mobility and the absence of cabling and other xed infrastructure have proven to be benecial 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 oce 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 aord. 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 dierent 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.
92D-Link DIR-842 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, oce, 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 Oce and Home Oce
• Stay on top of everything at home as you would at oce
• Remotely access your oce network from home
• Share Internet connection and printer with multiple computers
• No need to dedicate oce space

Where is wireless used?
Wireless technology is expanding everywhere not just at home or oce. 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, coee 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 signicantly reduce any interference that the appliances might cause since they operate on same frequency.
94D-Link DIR-842 User Manual
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 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.

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.
