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 rewalls (SPI and NAT) to prevent potential attacks across the
Internet, and includes MAC address ltering 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 o.
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 congured, 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 congure 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 ash on and o 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 oce. 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 aect wireless performance. Large objects such as sh tanks, mirrors, ling 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 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.
