Introduction

The DWL-1750 conforms to the 802.11 standard and covers a large operating distance, providing an 11Mbps outdoor WLAN which enables users to access the Internet or an organization network.s

The D-Link AirPremier DWL-1750 features a die-cast watertight housing and a built-in lightning protector to protect it from harsh environmental conditions, including extreme variance in temperature. It also includes Power over Ethernet (PoE) and a unique outdoor remote-mounted design for easy installation.

The DWL-1750 is suitable for manufacturing plants, industrial sites, military bases, universities, hotels, airports and golf courses.

With a built-in firewall, the DWL-1750 can operate as a NAT inbound virtual server and provides IP based access control. Denial of Service (DoS) protection is also included with the DWL-1750 to prevent the wireless network from being hacked. The DWL-1750 is easily managed via a web-based user interface, Telnet, or RS-232 console configuration. The DWL-1750 can also be managed remotely through SNMP (MIB I & MIB II) support.

System Requirements for Configuration:

Computers with Windows, Macintosh, or Linux-based

operating systems with an installed Ethernet adapter

Internet Explorer Version 6.0 or Netscape Navigator

Version 6.0 and Above

Connections

Special serial port (optional)

Connect one end of the MIL-C-5015 style RS232 console port cable to this port; connect the other end to a Serial Port on a computer that is running a terminal emulation program. Set the terminal to 15200 Baud, No Parity, 8 data bits, 1 stopbit and ANSI compatible.

Note: This connection is optional. Use this console connection only if you are configuring the DWL-1750 via the console.

Power & Data Output Port

Attach one end of the special Ethernet cable to this port; attach the other end to the Special Ethernet Port on the DWL-1750.

Outdoor Installation

The DWL-1750 can be mounted on the side of a building or mounted to a mast as shown above. A wall mount is a convenient location if the roof overhang is not excessive and/or the location is high enough to provide a clear line of sight.

Grounding

A safety grounding system is necessary to protect your outdoor installation from lightning strikes and the build-up of static electricity. Direct grounding of the antenna mast and the DWL-1750 is very important. The grounding system must comply with the National Electrical Code and the safety standards that apply in your country. Always check with a qualified electrician if you do not know how to properly ground the DWL-1750.

Antenna Mast Requirements

To accommodate the outdoor antennas, the antenna mast must satisfy the following requirements:

The construction of the mast must be of a sturdy, weatherproof and

no corrosive material like examples of galvanized or stainless steel construction pipe.

Typical diameter of the mast should be between 35 mm (1.4 in.) and

41 mm (1.625 in.). Subjecting to the type of antenna that you intend to install other diameters may be possible as well.

The height of the antenna mast must be sufficient to allow the

antenna to be installed at least 1.5 m (5 ft.) above the peak of roof. If the roof is metal, then the height of the antenna should be a minimum of 3 m (10 ft) above the roof.

The mast or wall-bracket must be free from any substance that may

avoid a good electrical connection with the antenna; for example, paint.

Antenna Alignment

For optimal performance of your wireless link, make sure that the antennas are properly aligned (facing one another “eye-to-eye”). To align the antennas:

Use a pair of binoculars and/or a map of the area and compass to

point the antennas to one another. Use the Utility - “Wireless Link Info” in the Web Configure as

described in the “Utility” section to analyze the radio link quality. The “Wireless Link Info” will enable you to display the levels of signal strength and link quality. Looking at the Wireless Link Info screen, you can interactively optimize antenna alignment if required, by making small modifications in the antenna orientation.

Alternatively, consult a professional Antenna Installation Service to

optimize the antenna alignment. Omni-directional antennas are characterized by a wide radiation

pattern. Therefore alignment of this type of antennas is less critical than for directional antennas.

Troubleshooting

This Chapter provides solutions to problems that can occur during the installation and operation of the DWL-1750 Wireless Bridge/Router. We cover various aspects of the network setup, including the network adapters. Please read the following if you are having problems.

Note: It is recommended that you use an Ethernet connection to

configure the DWL-1750 Wireless Bridge/Router.

1.The computer used to configure the DWL-1750 cannot access the Configuration menu.

Check that the Ethernet Cable is being used correctly. The

Crossover Ethernet cable that comes with the DWL-1750 is used only when the unit is connected to your PC directly. If the DWL-1750 is connected to a switch, a Straight-through cable must be used, not a Crossover cable.

Check that the Ethernet Adapter is working properly. Please

see item 3 (Check that the drivers for the network adapters are installed properly) in this Troubleshooting

section to check that the drivers are loaded properly. Check that the IP Address is in the same range and subnet

as the DWL-1750. Please see Checking the IP Address in Windows XP in the Networking Basics section of this

manual.

Note: The default Ethernet IP Address of the DWL-1750 is 192.168.0.50; the default wireless IP Address is 192.168.1.50. All the computers on the network must have a unique IP Address in the same range, e.g., 192.168.0.x. Any computers that have identical IP Addresses will not be visible on the network. They must all have the same subnet mask, e.g., 255.255.255.0

Do a Ping test to make sure that the DWL-1750 is

responding. Go to Start>Run>Type Command>Type ping

192.168.0.50. A successful ping will show four replies.

Note: If you have changed the default IP Address, make sure to ping the correct IP Address assigned to the DWL-1750.

Troubleshooting (continued)

2. The wireless client cannot access the Internet in the Infrastructure mode.

Make sure the wireless client is associated and joined with the correct Access Point. To check this connection: Right-click on the Local Area Connection icon in the taskbar> select View Available Wireless Networks. The Connect to Wireless Network screen will appear. Please make sure you have selected the

correct available network, as shown in the illustration below.

default

Check that the IP Address assigned to the wireless adapter is within the

same IP Address range as the access point and gateway. (Since the DWL-1750 has a wireless IP Address of 192.168.1.50, wireless adapters must have an IP Address in the same range, e.g., 192.168.1.x. Each device must have a unique IP Address; no two devices may have the same IP Address. The subnet mask must be the same for all the computers on the network.) To check the IP Address assigned to the

wireless adapter, double-click on the Local Area Connection icon in the taskbar > select the Support tab and the IP Address will be displayed. (Please refer to Checking the IP Address in the Networking

Basics section of this manual.)

If it is necessary to assign a Static IP Address to the wireless adapter,

please refer to the appropriate section in Networking Basics. If you are entering a DNS Server address you must also enter the Default

Gateway Address. (Remember that if you have a DHCP-capable router, you will not need to assign a Static IP Address. See Networking

Basics: Assigning a Static IP Address.)

Troubleshooting (continued)

2. The wireless client cannot access the Internet in the Infrastructure mode. (continued)

Check to make sure that the Router in your network is functioning properly

by pinging it. If the router is not functioning properly, it will not connect to the Internet. If you need to find out how to ping network devices, please refer to “Checking the Wireless Connection by pinging” in the Networking Basics section of this manual.

Check to make sure that the DNS server in your network is functioning properly

by pinging it. If the DNS server is not functioning properly, you may be unable to access the Internet. Typically, your ISP (Internet Service Provider) will be able to give you the DNS server information. If you need to find out how to ping network devices, please refer to “Checking the Wireless Connection by pinging” in the Networking Basics section of this manual.

3. Check that the drivers for the network adapters are installed properly.

You may be using different network adapters than those illustrated here, but this procedure will remain the same, regardless of the type of network adapters you are using.

4. What variables may cause my wireless products to lose reception?

D-Link products let you access your network from virtually anywhere you want. However, the positioning of the products within your environment will affect the wireless range. Please refer to Installation Considerations in the Wireless Basics section of this manual for further information about the most advantageous placement of your D-Link wireless products.

6. Why can’t I get a wireless connection?

If you have enabled Encryption on the DWL-1750, you must also enable encryption on all wireless clients in order to establish a wireless connection.

Make sure that the SSID on the Access Point and the Wireless Client are

exactly the same. If they are not, wireless connection will not be established.

Disable all security settings (WEP, MAC Address Control).

Turn off your DWL-1750 and the client (the device to which it is commu-

nicating). Turn the DWL-1750 back on again, and then turn on the client. Make sure that all devices are set to Infrastructure mode.

Check that the LED indicators are indicating normal activity. If not, check

that the AC power and Ethernet cables are firmly connected.

Check that the IP Address, subnet mask, and gateway settings are cor-

rectly entered for the network.

7. I forgot my encryption key

Reset the DWL-1750 to its factory default settings and restore the other

devices on your network to their default settings. You will lose the current configuration settings. Reset and restore the DWL-1750 to the factory default settings, without WEP encryption, by using Telnet or the Console connection. Please see the Appendix in this manual for information on how to use Telnet and/or the Console connection.

Appendix 1: Telnet Configuration

The DWL-1750 is designed to operate as shipped from the factory without any special set-up. However, it has many options and parameters that can be changed if users have special requirements. Most of the management functions can be accessed using TCP/ IP protocol; it can also be configured by Telnet/Console.

Configure the DWL-1750 using a Telnet session on a wired LAN attached computer. To use the Telnet session, you can simply open a Telnet window using the IP address that has been assigned to the DWL-1750.

1. Go to Start >Run; open the Run dialog box. Enter telnet 192.168.0.50 (the default terminal type of Telnet is VT100; the default

Appendix 3: Wireless Basics

D-Link wireless products are based on industry standards to provide easy-touse and compatible high-speed wireless connectivity within your home, business or wherever a wireless network is available. D-Link wireless products will allow you access to the data you want, when and where you want it. You will be able to enjoy the freedom that wireless networking brings.

A wireless local area network (WLAN) is a cellular computer network that transmits and receives data with radio signals instead of wires. WLANs are used increasingly in both home and office environments, and public areas such as airports, coffee shops and universities. Innovative ways to utilize WLAN technology are helping people to work and communicate more efficiently. Increased mobility and the absence of cabling and other fixed infrastructure have proven to be beneficial 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 Access Point is a device that can be used to provide this link.

Wireless Basics (continued)

People use WLAN technology for many different purposes:

Mobility - Productivity increases when people have access to data in any

location within the operating range of the WLAN. Management decisions based on real-time information can significantly improve worker efficiency.

Low Implementation Costs – WLANs are easy to set up, manage,

change and relocate. Networks that frequently change can benefit from a WLAN ease of implementation. WLANs can operate in locations wheres installation of wiring may be impractical.

Installation and Network Expansion - Installing a WLAN system can be

fast and easy and can eliminate the need to pull cable through walls and ceilings. Wireless technology allows the network to go where wires cannot go-even outside the home or office.

Scalability ?WLANs can be configured in a variety of ways to meet the

needs of specific applications and installations. Configurations are easily changed and range from peer-to-peer networks suitable for a small number of users to larger infrastructure networks to accommodate hundreds or thousands of users, depending on the number of wireless devices deployed.
