4DWL-G650M User’s ManualD-Link Systems, Inc.The D-Link DWL-G650M 108G MIMO Wireless Notebook Adapter is an 802.11g high-performance, wireless adapter that brings wireless networking to your laptop or desktop PC. With a maximum wireless signal rate of up to 108Mbps, you can connect to a wireless network at home, at the office or at any wireless hotspot. Now you can stay connected wherever you are and wherever you go. The DWL-G650M is Wi-Fi compatible, meaning that it can connect and interoperate with other 802.11b and 802.11g Wi-Fi-compliant wireless routers, access points and adapters. The DWL-G650M connects to any available Cardbus slot on a laptop Windows -based computer. A laptop computer with a DWL-G650M can be positioned virtually anywhere at a workstation to achieve the best available wireless signal reception - whether that workstation is in your office, on your deck or patio, by the pool, at the local coffee shop, or in an airport terminal while waiting to board your next flight.The adapter works with Microsoft Windows XP/2000 operating systems to ensure that you’ll be up and running on a wireless network in just a matter of seconds. The DWL-G650M provides an increased level of security with WPA-PSK. WPA-Personal is directed at home users who do not have the server based equipment required for user authentication. The method of authentication is similar to WEP because you define a “Pre-Shared Key” on the wireless router/AP. Once the pre-shared key is confirmed and satisfied on both the client and access point, then access is granted. the encryption method used is referred to as the Temporal Key Integrity Protocol (TKIP), which offers per-packet dynamic hashing. It also includes an integrity checking feature which ensures that the packets were not tampered with during wireless transmission.Introduction Introduction*Maximum wireless signal rate derived from IEEE Standard 802.11g specifications. Actual data throughput will vary. Network conditions and evironmental factors lower actual data throughput rate.

6DWL-G650M User’s ManualD-Link Systems, Inc.Wireless BasicsWireless BasicsWireless 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. 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. 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 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.
7DWL-G650M User’s Manual D-Link Systems, Inc.Standards-Based TechnologyThe DWL-G650M Wireless Cardbus Adapter 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 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. The D-Link DWL-G650M 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 section of this manual.The DWL-G650M 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-G650M is interoperable with existing compatible 2.4GHz wireless technology with data transfer speeds of up to 11Mbps. Wireless Basics
8DWL-G650M User’s ManualD-Link Systems, Inc.Installation ConsiderationsThe DWL-G650M 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:Installation ConsiderationsKeep the number of walls and ceilings between the DWL-G650M and other network devices to a minimum - each wall or ceiling can reduce your DWL-G650M’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 devices or appliances that generate RF noise.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.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.   
