Wireless Network

Network Topology

A wireless LAN is a group of computers, each equipped with one Instant Wireless Series adapter. Computers in a wireless LAN must be configured to share the same radio channel.

The Instant Wireless Series adapters provide access to a wired LAN for wire- less workstations. An integrated wireless and wired LAN is called an infra- structure configuration. A group of Instant Wireless Series adapter users and an Instant Wireless Wireless-G Access Point compose a Basic Service Set (BSS). Each Instant Wireless Series adapter PC in a BSS can talk to any com- puter in a wired LAN infrastructure via the Wireless-G Access Point.

An infrastructure configuration extends the accessibility of an Instant Wireless Series adapter PC to a wired LAN, and doubles the effective wireless trans- mission range for two Instant Wireless Series adapter PCs. Since the Wireless- G Access Point is able to forward data within its BSS, the effective transmis- sion range in an infrastructure LAN is doubled.

Roaming

Infrastructure mode also supports roaming capabilities for mobile users. More than one BSS can be configured as an Extended Service Set (ESS). This con- tinuous network allows users to roam freely within an ESS. All PCs equipped with an Instant Wireless Series adapter within one ESS must be configured with the same ESS ID and use the same radio channel.

Before enabling an ESS with roaming capability, choosing a feasible radio channel and optimum Wireless-G Access Point position is recommended. Proper Access Point positioning combined with a clear radio signal will great- ly enhance performance.

Wireless-G Access Point

Chapter 3: Getting to Know the Wireless-G Access Point

The Wireless-G Access Point’s Back Panel

The Access Point’s ports, where a network cable is connected, are located on the Access Point’s back panel.

	Figure 3-1
Reset Button	There are two ways to Reset the Access Point’s factory
	defaults. Either press the Reset Button using a small,
	pointed object like a ball-point pen, for approximately ten
	seconds, or restore the defaults from the password tab in
	the Access Point’s Web-Based Utility.
LAN	This LAN (Local Area Network) port connects to
	Ethernet network devices, such as a hub, switch, or
	router.
Power	The Power port is where you will connect the power
	adapter.

Important: Resetting the Access Point will erase all of your settings (WEP Encryption, Wireless and LAN settings, etc.) and replace them with the factory defaults. Do not reset the Access Point if you want to retain these settings

WAP54G specifications

The D-Link WAP54G is a wireless access point that offers a variety of features aimed at enhancing network connectivity and performance. Designed for small to medium-sized environments, this device is an essential component for creating a reliable wireless network. With its impressive capabilities, the WAP54G easily integrates into existing networks, providing enhanced coverage and flexibility.

One of the main features of the WAP54G is its support for the IEEE 802.11g standard, which allows for data transfer rates of up to 54 Mbps. This standard is backward compatible with 802.11b devices, ensuring that users can maintain connectivity with older hardware. This level of compatibility makes the WAP54G a versatile choice for diverse networking needs.

The device is equipped with advanced security features, including WPA and WPA2 encryption protocols, ensuring that users can protect their network from unauthorized access. These security measures are essential in today’s world, where data breaches are increasingly common. Additionally, the WAP54G supports MAC address filtering, which further restricts access to only authorized devices.

For connectivity, the WAP54G includes multiple Ethernet ports, allowing it to be connected directly to a wired network. This feature enables the access point to bridge the gap between wired and wireless devices, facilitating seamless communication. Moreover, the WAP54G supports Power over Ethernet (PoE), which simplifies installation by allowing it to receive power and data through a single Ethernet cable. This is particularly beneficial in environments where power outlets are limited or difficult to access.

Another noteworthy aspect of the WAP54G is its coverage capabilities. With its adjustable antennas, users can optimize signal distribution throughout a building, overcoming common obstacles such as walls and furniture that can hinder wireless performance. The access point also boasts a user-friendly web-based interface, making it easy to configure and manage settings for both novice and experienced users alike.

In terms of reliability, the D-Link WAP54G features a solid build quality and a compact design, allowing it to fit seamlessly into various environments. The device is also equipped with LED indicators that provide real-time status updates on power, Ethernet connection, and wireless activity, enabling users to monitor their network easily.

Overall, the D-Link WAP54G is a robust wireless access point that combines speed, security, and flexibility, making it an excellent choice for enhancing network performance in both home and office settings.
