3. Wireless Basics
D-Link Air 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 Air 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 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 (AP) 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.

Wireless Basics
Network Expansion - Wireless technology allows the network to go where
wires cannot go.
Reduced Cost-of-Ownership - While the initial investment required for
wireless LAN hardware might be higher than the cost of wired LAN hardware,
overall installation expenses and life-cycle costs will be significantly lower.
Long-term cost benefits are greatest in dynamic environments requiring
frequent moves, adds, and changes.
Scalability – Wireless Local Area Networks (WLANs) can be configured in a
installations. Configurations are easily changed and range from peer-to-peer
networks suitable for a small number of users to full infrastructure networks
of thousands of users that allow roaming over a broad area.
D-Link Air Wireless Family of LAN products include:
2.4GHz Wireless Cardbus Adapters used with laptop
computers (DWL-610)
2.4GHz Wireless PCI cards used with desktop computers
(DWL-510)
2.4GHz Wireless Access Points (DWL-700AP)
2.4GHz Wireless Broadband Router (DI-514)
Standards - Based Technology
The IEEE standard-based technology assures that the D-Link Air
Products are interoperable with existing compatible 2.4GHz wireless
technology. This means you will be able to transfer large files quickly or
even watch a movie in MPEG format over your network without noticeable
delays. The technology works by using multiple frequencies in the 2.4GHz
range at speeds up to 11 Mbps.

Installation Considerations
Designed to go up to 984 feet (300 meters) outdoors and up to 328 feet
(100 meters) indoors, D-Link’s Air DWL-700AP 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 wireless Access
Point and your receiving device (e.g., the DWL-610) 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 Access Points,
Residential Gateways, and computers so that the number of walls or
ceilings is minimized.
2. Be aware of the direct line between Access Points, Residential
Gateways (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 the Access Points and adapters 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 Access Points,
and computers with wireless adapters so that the signal passes through
drywall or open doorways and not other materials.
4. Make sure that the device’s antenna is positioned for best reception by
using the software signal strength tools included with your product.
5. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical
devices or appliances that may generate extreme RF noise.
For the average home, signal range should not be an issue. If you
experience low or no signal strength in areas of your home that you wish to
access, consider positioning the Access Point in a location directly between
the computers with wireless adapters. Additional Access Points can be
connected to provide better coverage in rooms where the signal does not
appear as strong as desired.

4. Getting Started
For the price of 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.
IP ADDRESS
An Infrastructure network contains an Access Point. The Infrastructure
Network example shown on the next page contains the following D-Link
network devices:
A wireless Access Point - D-Link Air DWL-700AP
An Ethernet Broadband Router - D-Link DI-604
A laptop computer with a wireless adapter - D-Link Air DWL-610
A desktop computer with a wireless adapter - D-Link Air DWL-510
A Cable modem - D-Link DCM-200
DHCP stands for Dynamic Host Configuration Protocol.
It is a protocol for assigning dynamic IP addresses “automatically.”
With a DHCP-capable gateway/router, there is
no need to manually assign an IP address.
Please note: If you have a DHCP-capable router, such as the D-
Link DI-604 or DI-614+, there is no need to assign an IP Address.
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 o
f
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.
Right out of the box, with its default settings, the DWL-700AP will
automatically connect with other D-Link Air or AirPlus products.

The DWL-700AP has a default IP Address of 192.168.0.50 with subnet
mask of 255.255.255.0
If you are using a D-Link router in your network, such as the DI-604, with the
factory default settings, you will not need to assign a static IP Address to the
computer that you are using to configure the Access Point. (Skip to Fig. 5.1:
entering the IP address)
If you are not using a D-Link router in your network, you will need to assign a
Static IP Address to the computer that you are using to configure the DWL-
700AP, with in the IP Address Range of the DWL-900AP+. Assign a static IP
address of 192.168.0.2 with subnet mask of 255.255.255.0 (Please see
Networking Basics in this manual for information on Assigning a Static IP
Address.) Note: Please write down the current IP address settings of the
computer. You may need to revert back to these settings after configuring the
DWL-900AP+.
After you have assigned a Static IP Address to the computer you are using for
configuration (if necessary), next you will assign the DWL-7000AP an IP
Address within the range of your existing network.
After changing the IP Address of the DWL-700AP you will need to enter the
IP into the address bar of your web browser to access the configuration page
of the DWL-700AP
If the computer had a static IP address, re-input that same address.
