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 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

Wireless Basics

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 Router is a

device used to provide this link.

People use wireless LAN 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 (Wireless Local Area Networks)

are easy to set up, manage, change and relocate. Networks that frequently

change, both physically and logically, can benefit from WLANs ease of

implementation. WLANs can operate in locations where installation of wiring

may be impractical.

Installation Speed and Simplicity - Installing a wireless LAN system

can be fast and easy and can eliminate the need to pull cable through walls

and ceilings.

Network Expansion - Wireless technology allows the network to go where

wires cannot go.

Scalability – Wireless Local Area Networks (WLANs) can be configured in

a variety of topologies 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.

Wireless Basics

The DI-764 is compatible with other D-Link AirPro 802.11a products, which

include:

♦5GHz Wireless Cardbus Adapters used with laptop computers

(DWL-A650)

♦5GHz Wireless PCI Adapters used with desktop computers

(DWL-A520)

The DI-764 is also compatible with the D-Link AirPlus 802.11b wireless family,

which includes:

♦Enhanced 2.4GHz Wireless Cardbus Adapters used with laptop

computers (DWL-650+)

♦Enhanced 2.4GHz Wireless PCI cards used with desktop computers

(DWL-520+)

Standards-Based Technology

The versatile DI-764 Multimode Wireless Broadband Router integrates both

802.11a and 802.11b standards into a single unit.

The IEEE 802.11a standard designates that devices may operate at an

optimal data rate of 54 Mbps (72 Mbps in proprietary Turbo mode.) This

means that in most environments, within the specified range of this device,

you will be able to transfer large files quickly or even watch a movie in

MPEG format over your network without noticeable delays. This technology

works by transmitting high-speed digital data over a radio wave utilizing

OFDM (Orthogonal Frequency Division Multiplexing) technology. OFDM

works by splitting the radio signal into multiple smaller sub-signals that are

then transmitted simultaneously at different frequencies to the receiver.

OFDM reduces the amount of crosstalk (interference) in signal

transmissions. D-Link AirPro 802.11a products will automatically sense the

best possible connection speed to ensure the greatest speed and range

possible.

Based on the IEEE 802.11b standard, the DI-764 is also interoperable with

existing compatible 2.4GHz wireless technology with data transfer speeds of

up to 22Mbps (with the D-Link AirPlus family of wireless devices,) as well as

standard 802.11b technology ( the D-Link Air family of wireless devices),

with speeds of up to 11Mbps.

Wireless Basics

Installation Considerations

The D-Link AirPro DI-764 lets you access your network, using a wireless

connection, from virtually anywhere. Keep in mind, however, that the

number, thickness and location of walls, ceilings or other objects that the

wireless signals must pass through may limit the range. Typical ranges vary

depending on the types of materials and background RF (radio frequency)

noise in your home or business. The key to maximizing wireless range is to

follow these basic guidelines:

1. Keep the number of walls and ceilings between the DI-764 and your

receiving device (e.g., the DWL-A650 or the DWL-650+) to a minimum -

each wall or ceiling can reduce your D-Link AirPro Wireless product’s

range from 3-90 feet (1-30 meters.) Position your receiving devices so

that the number of walls or ceilings is minimized.

2. Be aware of the direct line between routers and computers. A wall that is

1.5 feet thick (.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!

Try to make sure that devices are positioned so that the signal will travel

straight through a wall or ceiling for better reception.

3. Building Materials make a difference - a solid metal door or aluminum

studs may have a negative effect on range. Try to position wireless

devices and computers with wireless adapters so that the signal passes

through drywall or open doorways and not other materials.

4. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical

devices or appliances that generate RF noise.

With a single IP Address from your Broadband Internet Service provider you

can share the Internet with all the computers on your local network, without

sacrificing speed or security, using D-Link Air networking products.

Getting Started

An Infrastructure wireless network contains an Access Point. The

Infrastructure Network example, shown here, contains the following D-Link

network devices:

A wireless Broadband Router - D-Link AirPro DI-764

A laptop computer with a wireless adapter - D-Link AirPro DWL-A650 or

AirPlus DWL-650+

A desktop computer with a wireless adapter - D-Link AirPro DWL-A520 or

AirPlus DWL-520+

A Cable modem - D-Link DCM-200

If you need to assign IP Addresses to the computers on the network,

please remember that the IP Address for each computer must be in

the same IP Address range as all the computers in the network, and

the Subnet mask must be exactly the same for all the computers in the

network.

For example: If the first computer is assigned an IP Address of

192.168.0.2 with a Subnet Mask of 255.255.255.0, then the second

computer can be assigned an IP Address of 192.168.0.3 with a Subnet

Mask of 255.255.255.0, etc.

IMPORTANT: If computers or other devices are assigned the same

IP Address, one or more of the devices may not be visible on the

network.

IP ADDRESS

Note: If you are using a DHCP-capable router in your network setup,

such as the DI-764, you will not need to assign a static IP Address.

Right out of the box, with its default settings, the DI-764 will

connect with other D-Link Air, AirPlus or AirPro products.

Please remember that D-Link AirPro wireless devices are pre-configured to connect

together, right out of the box, with the default settings.

You will need broadband Internet access (Cable/DSL) subscription

Consult with your Cable/DSL provider for proper installation of the modem

Connect the modem to the DI-764 multimode wireless broadband router

(see the Quick Installation Guide included with the DI-764.)

If you are connecting a desktop computer to your network, you can install the

D-Link AirPro DWL-A520 (or the DWL-520+) wireless PCI adapter into an

available PCI slot. (See the Quick Installation Guide included with the DWL-

A520 or the DWL-520+.)

If you are connecting a laptop computer to your network, install the drivers for the

wireless cardbus adapter (D-Link AirPro DWL-A650) into a laptop computer .

Remote Management

Remote Management allows the DI-764 to be configured from the Internet by a web

browser. A username and password is still required to access the Web-Management

interface. In general, only a member of your network can browse the built-in web

pages to perform “Administrator” tasks. This feature enables you to perform

“Administrator” tasks from the remote (Internet) host.

IP Address: Internet IP address of the computer that has access to the Router. It is

not recommended that you set the IP address to * (star), because this allows any

Internet IP address to access the Router, which could result in a loss of security for

your network. If you elect to enable Remote Management, make sure to enter the

IP Address of the remote computer allowed to configure the DI-764.

Port: For security purposes, select a separate port number used to access the

Router. (The following is an example only; you may use a different port number.)

Example: http://x.x.x.x:8080 where x.x.x.x is the WAN IP address of the Router

and 8080 is the port used for the Web-Management interface.

and click Ping

if you choose to block WAN Ping, the WAN IP Address of the

DI-764 will not respond to pings. Blocking the Ping may provide

some extra security from hackers.

the DI-764 supports VPN (Virtual Private Network) pass-through

for both PPTP (Point-to-Point Tunneling Protocol) and IPSec

(IP Security). Once VPN pass-through is enabled, there is no

need to open up virtual services. Multiple VPN connections

can be made through the DI-764. This is useful when you have

many VPN clients on the LAN network.
