Section 1 - Product Overview  
Introduction  
The D-Link 4G LTE Router allows users to access worldwide mobile broadband networks, and share them with a number of  
wired and wireless devices. Once connected, users can transfer data, stream media, and send SMS messages. Simply insert  
your UMTS/HSUPA SIM card, and share your 3G/4G Internet connection through a secure 802.11n wireless network or using  
any of the four 10/100 Ethernet ports.  
The DWR-921 keeps your wireless network safe with WPA/WPA2 wireless encryption, preventing unauthorized users from  
accessing your network. The DWR-921 utilizes dual-active firewalls (SPI and NAT) to prevent potential attacks across the  
Internet, and includes MAC address filtering to control which clients can access your network, and what content they can  
access.  
The DWR-921 4G LTE Router can be installed quickly and easily almost anywhere. This router is great for situations where an  
impromptu wireless network is required, or wherever conventional network access is unavailable. The DWR-921 can even be  
installed in buses, trains, or boats, allowing passengers to access the Internet while commuting.

Section 2 - Installation  
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.  
Connect to Your Network  
1. Ensure that your DWR-921 4G LTE Router is disconnected and powered off.  
2. Insert a standard (U)SIM card into the SIM card slot on the back of the router as indicated by the SIM card logo next to the slot. The gold contacts  
should face downwards.  
Caution: Always unplug/power down the router before installing or removing the SIM card. Never insert or remove the SIM card while the router  
is in use.  
3. Insert your Internet/WAN network cable into the WAN port on the back of the router.  
Note: The 3G/4G connection can also be used as a backup WAN. Once a backup is configured, the router will automatically use 3G for the Internet  
connection if the Ethernet WAN is not available.  
4. Insert the Ethernet cable into the LAN Port 1 on the back panel of the DWR-921 4G LTE Router and an available Ethernet port on the network  
adapter in the computer you will use to configure the router.  
Note: The DWR-921 4G LTE Router LAN Ports are Auto-MDI/MDIX, so both patch and crossover Ethernet cables can be used.  
5. Connect the power adapter to the power connecter on the back panel of your DWR-921 4G LTE Router. Plug the other end of the power adapter  
into a wall outlet or power strip and turn the device on.  
a. The Status LED will light up to indicate that power has been supplied to the router.  
b. The LEDs on the front panel will flash on and off as the 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, Status, WAN, WLAN, and any LAN  
Port LEDs that are connected to computers or other devices.

Section 2 - Installation  
Wireless Installation Considerations  
The DWR-921 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 office. The key to maximizing  
the wireless range is to follow these basic guidelines:  
1. Minimize the number of walls and ceilings between the 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 can appear 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 or drywall. Materials such as  
glass, metal, brick, insulation, concrete, and water can affect wireless performance. Large objects such as fish tanks, mirrors, filing cabinets, metal  
doors, and aluminum studs may also have a negative effect on range.  
4. If you are using 2.4 GHz cordless phones, make sure that the 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,  
fluorescent lights, and home security systems may dramatically degrade wireless connectivity.

Section 5 - Troubleshooting  
Troubleshooting  
This chapter provides solutions to problems that can occur during the installation and operation of the DWR-921. Read the following descriptions  
if you are having problems.  
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 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,  
andWindows® 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 5 - Troubleshooting  
• Configure your Internet settings:  
• Go to Start > Settings > Control Panel. Double-click the Internet Options Icon. From the Security tab, click the Reset All Zones to  
Default Level 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. Please note that 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, and the default username is admin and the password should be left blank.

Appendix A - Wireless Basics  
Tips  
Here are a few things to keep in mind when installing 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 and 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.  
Security  
Don’t let you unauthorized users connect to your wireless network. Secure your wireless network by turning on the WPA or WEP security feature  
on the router. Refer to “Wireless Settingson page 22 for detailed information on how to set up wireless security.

Appendix B - Networking Basics  
Networking Basics  
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® Vistausers 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.

Appendix B - Networking Basics  
Statically Assign an IP address  
If you are not using a DHCP capable gateway/router, or you need to assign a static IP address, please follow the steps below:  
Step 1  
Windows® Vista-  
Windows® XP -  
Windows® 2000 -  
Step 2  
Click on Start > Control Panel > Network and Internet > Network and Sharing Center > Manage Network Connections.  
Click on Start > Control Panel > Network Connections.  
From the desktop, right-click My Network Places > Properties.  
Right-click on the Local Area Connection which represents your network adapter and select Properties.  
Step 3  
Highlight Internet Protocol (TCP/IP) 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 192.168.0.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  
Default Gateway the same as the LAN IP address of your router (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.  
Step 5  
Click OK twice to save your settings.
