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. 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 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 to 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.

Wireless Basics

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 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 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.

Inexpensive Solution - Wireless network devices are as competitively priced as
conventional Ethernet network devices.

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 Peer­to-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.

Standards-Based Technology

The DWL-G680 Wireless 108G Notebook Adaper utilizes the 802.11g standard.

The IEEE 802.11g standard is an extension of the 802.11b standard. It increases the
data rate up to 54Mbps within the 2.4GHz band, utilizing OFDM technology.

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 high­speed 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.
The D-Link DWL-G680 will automatically sense the best possible connection speed to
ensure the greatest speed and range possible.

802.11g offers the most advanced network security features available today, including:
WPA , 802.1x, TKIP, AES and Pre-Shared Key mode. These security features are
explained in more detail in the

Introduction

Wireless Basics

section of this manual.

The DWL-G680 is backwards compatible with 802.11b devices. This means that if you
have an existing 802.11b network, the devices in that network will be compatible with

802.11g devices at speeds up to 11Mbps in the 2.4GHz range. Also based on the IEEE

802.11b standard, the DWL-G680 is interoperable with existing compatible 2.4GHz
wireless technology with data transfer speeds of up to 11Mbps.

Installation Considerations

The DWL-G680 lets you access your network using a wireless connection from virtually
anywhere within its operating range. 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:



Keep the number of walls and ceilings between the DWL-G680 and other network
devices to a minimum - each wall or ceiling can reduce your DWL-G680’s range
from 3-90 feet (1-30 meters.) Position your devices so that the number of walls or
ceilings is minimized.

Be aware of the direct line between network devices. 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! Position devices so that the
signal will travel straight through a wall or ceiling (instead of at an angle) for better
reception.

Installation Considerations



Building materials can impede the wireless signal - 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.

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



appliances that generate RF noise.

Assigning a Static IP Address in Windows XP/2000

Note: Many broadband routers will automatically assign IP addresses to the
computers on the network, using DHCP (Dynamic Host Configuration Protocol)
technology. If you are using a DHCP-capable router you will not need to
assign static IP addresses.

If you are not using a DHCP capable router, or you need to assign a static IP address,
please follow these instructions:

(The examples below are illustrated in Windows XP. If you have another operating system,
these solutions will still apply although the appearance on your computer screen may
differ.)

2. 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.

3. Why does my wireless connection keep dropping?

If you are using 2.4GHz cordless phones, X-10 equipment or other home security
systems, ceiling fans, and lights, your wireless connection will degrade dramatically or
drop altogether.

Try changing the channel on your router, access point and wireless adapter to a different
channel to avoid interference.

Troubleshooting

Keep your product away (at least 3-6 feet) from electrical devices that generate RF
noise, like microwaves, monitors, electric motors, etc.

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

If you have enabled encryption on the DWL-G680, you must also enable
encryption on all wireless devices in the network in order to establish a wireless
connection.

Make sure that the encryption bit level/TYPE is the same on the AP/router and
the DWL-G680.

Make sure that the SSID on the wireless router (if you have one in your network)
and the DWL-G680 are exactly the same. If they are not,
wireless connection will not be established. The default SSID is default.

option, replace the defective Hardware or any part thereof with any reconditioned product that D-Link reasonably determines
is substantially equivalent (or superior) in all material respects to the defective Hardware. Repaired or replacement hardware
will be warranted for the remainder of the original Warranty Period or ninety (90) days, whichever is longer, and is subject to
the same limitations and exclusions. If a material defect is incapable of correction, or if D-Link determines that it is not
practical to repair or replace the defective Hardware, the actual price paid by the original purchaser for the defective

price paid that is attributable to the Software. Except as otherwise agreed by D-Link in writing, the replacement Software is
provided only to the original licensee, and is subject to the terms and conditions of the license granted by D-Link for the

discretion that it is not practical to replace the non-conforming Software, the price paid by the original licensee for the non­conforming Software will be refunded by D-Link; provided that the non-conforming Software (and all copies thereof) is first
returned to D-Link. The license granted respecting any Software for which a refund is given automatically terminates.
