Introduction
The versatile D-Link Air DWL-700APWirelessAccess Point is an 802.11b high-perfor-
mance wireless device that can be used in one of three modes: as an access point, a
repeater, or a wireless client. It is an ideal way to extend the reach and number of
computers connected to your wireless network.
TheDWL-700APiscompatiblewith existing802.11b devicessuch astheD-Link Air and
AirPlus family of products including the DWL-650 and DWL-650+ Wireless Cardbus
Adapters, the DI-614+ Wireless Router, and the DWL-120 Wireless USBAdapter.
The IEEE 802.11b Ethernet standard allows you to connect computers and 802.11b
compatible devices at speeds up to 11Mbps, dependent upon the distance between
wirelessadapters, the configuration of your working environment, or the capabilities or
limitations of your computer systems.
After completing the steps outlined in the Quick Installation Guide (included in your
package)you will havethe ability to share information and resources, such as files and
printers,and enjoy thefreedom that wirelessnetworking brings.

Wireless Basics
D-Link wireless products are based on industry standards to provide easy-to-use and
compatiblehigh-speedwirelessconnectivitywithinyourhome,businessorpublicaccess
wirelessnetworks. D-Link wireless products willallow you accessto the data you want,
whenandwhereyouwantit.Youwillbeabletoenjoythefreedomthatwirelessnetworking
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
bothhomeand office environments,andpublic areas suchasairports, coffeeshopsand
universities.Innovativeways toutilizeWLAN technologyarehelping peopletowork and
communicatemore efficiently. Increased mobility and the absence of cabling and other
fixedinfrastructure haveproven to be beneficial formany 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
Ethernetadapter cards.
Peopleuse 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
informationcan significantlyimprove workerefficiency.
Low Implementation Costs –WLANs are easy to set up, manage, change and
relocate. Networks that frequently change can benefit from WLANs ease of
implementation. WLANs can operate in locations where installation of wiring may be
impractical.
Installation and Network Expansion - Installing a WLAN system can be fast
andeasy and caneliminate the needto pull cable through walls and ceilings. Wireless
technologyallows the network to gowhere wirescannot go - even outsidethe 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
fromPeer-to-Peer networks suitablefor asmallnumber ofusers to largerinfrastructure
networksto accommodate hundreds or thousands of users, dependingon the number
ofwireless devicesdeployed.
Inexpensive Solution - Wireless network devices are as competitively priced as
conventionalEthernetnetworkdevices.

Installation Considerations
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
typesofmaterials andbackground RF (radiofrequency) noise inyour home orbusiness.
The key to maximizing wireless range is to follow these basic guidelines:
Wireless Basics (continued)
BuildingMaterialscanimpedethewirelesssignal-asolidmetaldoororaluminum
studsmayhavea negative effectonrange.Try to positionwirelessdevicesand
computerswith wirelessadapters sothat the signal passes through drywall or
opendoorways andnot other materials.

a2-degreeangle it looksover 42 feet(14meters) thick!Positiondevices so that
thesignal willtravel straightthrough awall or ceiling (instead of at anangle) for
betterreception.

Keepthe number of walls and ceilings between the DWL-700AP and
other network devices to a minimum - each wall or ceiling can reduce
your D-Link Air Wireless product’s range from 3-90 feet (1-30 meters.)
Position your devices so that the number of walls or ceilings is minimized.

Keep your product away (at least 3-6 feet or 1-2 meters) from electrical
devicesor appliances thatgenerate RF noise.

Please remember that D-Link Air wireless devices are pre-configured to connect
together, right out of the box, with their default settings.
Youwillneedbroadband Internetaccess (aCable or DSL-subscriberline into

If you are connecting a desktop computer in your network, you can install the
D-Link Air DWL-520 Wireless PCIAdapter into an available PCI slot on your
desktopcomputer.

Dynamic IPAddress: Select this option if you would like to have an IP address
automatically assigned to the DWL-700AP by a DHCP server in your network.
DHCP standsfor Dynamic Host Configuration Protocol.It isa protocol for assigning
dynamic IPaddresses “automatically.” With a DHCP Server there is no need to
manually assign an IP address.
Static IP Address: Select this option if you are manually assigning an IP address.
IPAddress: 192.168.0.50 is the default IPaddress of the access point.
Subnet Mask: 255.255.255.0 is the default subnet mask.All devices on the
network must have the same subnet mask to communicate on the network.

IPAddress
If you need to assign static IP addresses to the devices in your network, please
remember that the IP address for each computer or device must be in the same IP
address range as all the devices in the network. Each device must also have the
same subnet mask. For example:Assign the first computer an IP address of
192.168.0.2and asubnet maskof 255.255.255.0, the second device an IP address
of192.168.0.3 anda subnetmask of 255.255.255.0, and so on. Devicesthat are
assigned the same IP address may not be visible on the network.
