Chapter 2: Planning your Wireless Network

Network Topology

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

The Linksys wireless adapters provide access to a wired LAN for wireless workstations. An integrated wireless and wired LAN is called an infrastructure configuration. A group of Linksys wireless adapter users and a Wireless-G Broadband Router compose a Basic Service Set (BSS). Each Linksys wireless adapter PC in a BSS can talk to any computer in a wired LAN infrastructure via the Wireless-G Broadband Router.

An infrastructure configuration extends the accessibility of a Linksys wireless adapter PC to a wired LAN, and doubles the effective wireless transmission range for two Linksys wireless adapter PCs. Since the Wireless-G Broadband Router is able to forward data within its BSS, the effective transmission 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 continuous network allows users to roam freely within an ESS. All PCs equipped with a Linksys wireless 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 Broadband Router position is recommended. Proper router positioning combined with a clear radio signal will greatly enhance performance.

WRT54G specifications

The Cisco Systems WRT54G is a cornerstone of home and small office networking, renowned for its robust features and reliability since its release in 2002. Widely acknowledged as one of the first consumer-grade routers to combine wireless and wired networking capabilities, the WRT54G has earned a legacy as a hallmark of simplicity and performance.

At the heart of its functionality is the 802.11g wireless standard, which allows for wireless connections at speeds of up to 54 Mbps. This technology ensures a reliable connection over significant distances, making it suitable for various home and office environments. The WRT54G operates on the 2.4 GHz frequency band, which provides compatibility with many devices but can be susceptible to interference from other electronic devices.

One of the standout features of the WRT54G is its user-friendly web interface, allowing even non-technical users to easily configure their network settings. This feature promotes security by enabling users to modify their network name, set up encryption protocols like WEP or WPA, and create a guest network for visitors. The router also incorporates a built-in firewall and supports Network Address Translation (NAT), adding an additional layer of security to users’ private networks.

The WRT54G boasts four Ethernet ports for wired connections, accommodating multiple devices simultaneously. This feature is particularly beneficial for users with desktop computers, gaming consoles, or network-attached storage devices requiring stable, high-speed connections. The ability to connect devices through Ethernet ensures that users can enjoy the benefits of a reliable and fast network, especially in environments where wireless connectivity may be limited.

Another distinguishing characteristic of the WRT54G is its open-source firmware capability, which has led to a devoted community of enthusiasts who have developed alternative firmware for greater customization and advanced features. This flexibility not only enhances the router's lifespan but also caters to users who require specific functionalities, such as advanced Quality of Service (QoS) settings or more extensive parental controls.

In conclusion, the Cisco Systems WRT54G remains a significant player in the realm of consumer networking due to its innovative features, ease of use, and adaptability. While newer models have since emerged, the WRT54G's enduring reputation speaks to its reliability and solid performance, making it a preferred choice for many users seeking to establish a dependable network.
