Section 1 - Product Overview

Introduction

The D-Link 4G LTE Router allows users to access worldwide mobile broadband networks. Once connected, users can transfer
data, stream media, and send SMS messages. Simply insert your 3G / 4G 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.

Keep your wireless network safe with WPA/WPA2 wireless encryption. The DWR-921 utilizes dual-active rewalls (SPI and
NAT) to prevent potential attacks across the Internet, and includes MAC address ltering to control access to your network.

The 4G LTE Router can be installed quickly and easily almost anywhere. This router is great for situations where an im­promptu wireless network must be set up, or wherever conventional network access is unavailable.

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.

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 congured, the router will automatically use 3G / 4G 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 congure 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 socket 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 DWR-921 4G LTE 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 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 oce. 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 aect wireless performance. Large objects such as sh tanks, mirrors, le cabinets, metal
doors, and aluminum studs may also have a negative eect 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.
