Introduction
Introduction
D-Link’s with a high-performance hardware platform specifically designed for corporate environments. The including the DWL-G680 High-Powered Wireless 108G Notebook Adapter.
Powered by D-Link 108G Technology, this High-Powered Notebook Adapter is capable of delivering a maximum wireless signal rate of up to 108Mbps* when used with other D-Link Wireless 108G devices. The DWL-G680 is also backward compatible with virtually all
802.11b/g networks and devices.
The high-powered output featured on the DWL-G680 offers extended wireless signal reception while adhering to industry standards. Higher output power allows this client device to receive and maintain strong signals from wireless routers and access points at further distances – this translates into more useable, real-world throughput from virtually anywhere in your wireless network.
The new business-class wireless LAN utility included with this device is capable of storing multiple SSIDs per profile. What this means to the notebook user is a hassle-free and automatic process when transitioning between or changing networks. Each time a user enters an area under a different SSID, the notebook adapter will automatically connect to the respective SSID to ensure a positive roaming experience. IT managers will also appreciate the Silent Installation feature of the DWL-G680. With this feature, the drivers can be configured to automatically install on the backend reducing the time needed to process and configure wireless network settings.

For accessing secure networks, this Wireless Notebook Adapter supports both Personal and Enterprise versions of WPA and WPA2. Now you can utilize EAP-TLS, EAP-TTLS and PEAP for secure user authentication through an 802.1x RADIUS server. Data traversing the wireless network is encrypted using either TKIP or AES.
The DWL-G680 can be used in peer-to-peer mode (ad-hoc) to directly connect to other
802.11b/g wirelessly enabled computers for direct file sharing, or in client mode (infrastructure) to connect with wireless access points or routers.
In addition to Wi-Fi certification for 802.11b and 11g, the DWL-G680 is also certified by Microsoft’s WHQL, to ensure compatibly with Microsoft Windows® XP and 2000. These certifications ensure both wireless compatibility, robust data encryption, and reliable performance. A perfect complement for your Adapter is a convenient solution for providing superior wireless connectivity for your notebook PC.

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.

Getting Started
There are basically two modes of networking:
Infrastructure – using an access point or router, such as the DI-624.
Ad-Hoc – directly connecting to another computer, for Peer-to-Peer communication,
using wireless network adapters on each computer, such as two or more DWL-G680 Wireless Laptop adapters.
On the following pages we will show you an example of an Infrastructure Network and an Ad-Hoc Network.
An Infrastructure network contains an access point or router.

When assigning 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.
