Section 2 - Installation
Before You Begin
Installation
This section will guide 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.
Ensure that your DWR-978 5G AC2600 Wi-Fi Router is disconnected and powered o before performing the steps below..
1. Verify that your SIM/UICC card is installed and has been activated by your carrier.
Caution: Always unplug/power down the router before installing or removing the SIM/UICC card. Never insert or remove the SIM/UICC card while
the router is in use.
2. Attach the included antennas to the back of the router, screwing them in clockwise. Arrange them so that they point upward.
3. Connect the power adapter to the socket on the back panel of your DWR-978. Plug the other end of the power adapter into a wall outlet or
power strip. Make sure the power button is in the “On” position.
a. The Power LED will light up to indicate that power is being supplied to the router and the router is turned on.
b. The LEDs on the front panel will ash on and o as the DWR-978 Mobile Router performs initialization and Internet connection processes.
c. After a few moments, if a connection has been established, the following LEDs will turn solid green: Power, Network, WiFi (if enabled), LAN
(if connected), WAN (if connected), and Signal Strength.
Note: By default, the DWR-978 uses the mobile network as the sole Internet connection. If you wish to use your mobile connection as a backup to
a wired connection, or you wish to use a wired connection exclusively, you must use the Optional Advanced Setup procedure.
4. Connect via Wi-Fi using the SSID and password printed on the bottom of the router, or through Ethernet via one of the LAN ports on the back
of your DWR-978.

Section 2 - Installation
Wireless Installation Considerations
The DWR-978 can be accessed using a wireless connection from anywhere within the operating range of your wireless network. Keep in mind that
the quantity, thickness, and location of walls, ceilings, or other objects that the wireless signals must pass through may limit the range of the wireless
signal. Ranges vary depending on the types of materials and background RF (radio frequency) noise in your home or oce. The key to maximizing
the wireless range is to follow these basic guidelines:
1. Minimize the number of walls and ceilings between the D-Link router and other network devices. Each wall or ceiling can reduce your adapter’s
range from 3 to 90 feet (1 to 30 meters).
2. Be aware of the direct line between network devices. A wall that is 1.5 feet thick (0.5 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. Try to position access points, wireless routers, and computers so that the signal passes through open doorways and drywall. Materials such as
glass, metal, brick, insulation, concrete, and water can aect wireless performance. Large objects such as sh tanks, mirrors, le cabinets, metal
doors, and aluminum studs may also have a negative eect on range.
4. If you are using 2.4 GHz cordless phones, make sure that the 2.4 GHz phone base is as far away from your wireless device as possible. The base
transmits a signal even if the phone is not in use. In some cases, cordless phones, X-10 wireless devices, and electronic equipment such as ceiling
fans, uorescent lights, and home security systems may dramatically degrade wireless connectivity.

Troubleshooting
This chapter provides solutions to problems that can occur during the installation and operation of the DWR-978. 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 these 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® 7 or higher
- Mozilla Firefox 3.5 or higher
- Google™ Chrome 8 or higher
- Apple Safari 4 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
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.

• 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. 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, 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
72D-Link DWR-978 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:
• Navigate to the conguration page.
• To change the MTU, enter the number in the MTU eld and click Apply 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 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 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 similarly to how cordless phones work, through radio signals that 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 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, university and high school campuses, airports, golf courses, and many other
outdoor venues.
75D-Link DWR-978 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. This 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 Uses/Benets
• 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 Uses/Benets
• 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
76D-Link DWR-978 User Manual
Appendix A - Wireless Basics
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 the 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.
77D-Link DWR-978 User Manual
Appendix A - Wireless Basics
Security
Turn on WPA2 encryption on the router to help protect your wireless network from unwanted access by people close to your
network, such as neighbors or intruders. Refer to the product manual for detailed 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 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 adapters. All the adapters must be in ad hoc mode to
communicate.

Step 2
Right-click on the Local Area Connection which represents your network adapter and select Properties.
Step 3
Highlight Internet Protocol Version 4 (TCP/IPv4) and click Properties.
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 192.168.1.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 Alternate
DNS is not needed or you may enter a DNS server from your ISP.

Wireless Security
This section will show you the dierent levels of security you can use to help protect your data from intruders. The DWR-978 oers 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 (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. WPA2 is based on 802.11i and uses Advanced Encryption Standard
(AES) instead of TKIP.
• User authentication, which is generally missing in WEP, which is encorporated through the extensible authentication
protocol (EAP). WEP regulates access to a wireless network based on a computer’s hardware-specic MAC address, which
is relatively simple to be snied out and stolen. EAP is built on a stronger public-key encryption system so that only
authorized network users should be able to 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. This is the technique typically used on home networks.
WPA/WPA2 incorporates user authentication through the Extensible Authentication Protocol (EAP). EAP is built on an even stronger key
encryption system to make it much more dicult for unauthorized network users to access the network. EAP is often used in corporate
or university environments.
