Section 2 - Installation
Wireless Installation Considerations
The DWR-720 can be accessed using a wireless connection from anywhere within the operating range of its 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 adversely aect wireless signals. 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 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) appears to be almost 3 feet (1 meter) thick at a
45-degree angle. At a 2-degree angle it appears 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 a 2.4 GHz cordless phone, 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.

Conguration
Initial Connection to the Router
This section will show you how to congure your new D-Link mobile router using the web-based conguration utility.
By default, the DWR-720 comes congured to work with most 3G SIM cards. Simply connect to it via Wi-Fi or use the included USB to access the
SIM’s 3G Internet connection. When conguring the router for the rst time, you will need to establish a direct connection with the router in order
to access the web-based conguration utility. This can be done using the included USB cable, or by connecting wirelessly to the DWR-720. Ensure
that the router is powered on and has sucient battery power before commencing the setup process.
Connect via USB
To connect to the router via USB, plug the provided micro USB cable into the micro USB port on the bottom of the router, and plug the other end
into an available USB port on your computer. Your router is now ready for conguration, please refer to Conguration Utility on page 14 to
continue the setup process.

Section 3 - Conguration
Connect via Wi-Fi
Note: The following example uses Windows 7’s built-in wireless connection utility. If you are using a dierent operating system, or a third party
connection utility, the process may be dierent. Please refer to the documentation that came with your operating system or wireless client for
further information on how to connect to a wireless network.
To connect to the router usingWi-Fi, open your operating system’s wireless networking utility
and scan for available networks to connect to. By default, the network name (SSID) of the
DWR-720 will be in the format dlink_DWR-720_xxxx, where “xxxx” represents the last four
character’s of the router’s MAC address.
Once you have located your DWR-720’s wireless network, connect to it.
