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 congured, 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 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.

802.11b and 802.11g devices. N only: Enable this mode if your network only has 802.11n devices. B/G/N mixed: Enable this mode if you have a mix of 802.11n,
802.11g, and 802.11b clients.
Enabling this feature will allow the router to scan for the best channel to use automatically.
A wireless network uses specic channels in the wireless spectrum to handle communication between clients. Some channels in your area may experience interference from other electronic devices. Choose the clearest channel to help optimize the performance and coverage of your wireless network, or enable Auto Channel Scan for the router to automatically select the best channel.
Visibility Status:
This setting determines whether the SSID will be Visible or Invisible to wireless clients looking for wireless networks.
Setting this to Invisible can increase the security of your network by hiding it, but clients will need to manually enter the SSID of your network to connect.

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 conguration 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
• • Netscape 8 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 dierent cable or connect
to a dierent 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 Zone Alarm, Black Ice, Sygate, Norton Personal Firewall,

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 securely 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 oce environments, and public areas such as airports, coee shops and universities. Innovative ways to utilize WLAN technology are helping people to work and communicate more eciently. Increased mobility and the absence of cabling and other xed infrastructure have proven to be benecial 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 oce network.
Why D-Link Wireless?
D-Lin k i s the w o r l d w id e leader an d a w a r d winning desi gn e r, d e ve l o p e r, an d m a nu f a cturer o f networking p r o d u c ts . D-Link delivers the performance you need at a price you can aord. D-Link has all the products you need to build your network.
How does wireless work?
Wireless works similar to how cordless phone work, through radio signals to 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 dierent 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 as seen in the picture, 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, college and high school campuses, airports, golf courses, and many other outdoor venues.
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 which makes it ideal for personal devices, such as mobile phones, PDAs, headphones, laptops, speakers, and other devices that operate on batteries.

Where is wireless used?
Wireless technology is expanding everywhere not just at home or oce. 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 Internet from remote locations like Airports, Hotels, Coee 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 signicantly reduce any interference that the appliances might cause since they operate on same frequency.
Security
Don’t let you next-door neighbors or intruders connect to your wireless network. Secure your wireless network by turning on the WPA or WEP security feature on the router. Refer to product manual for detail information on how to set it up.

Wireless Modes

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.
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 cardbus adapters. All the adapters must be in Ad-Hoc mode to communicate.
