Instant WirelessTM Series

3.I cannot communicate with the other computers linked via Ethernet in the Infrastructure configuration.

•Make sure that the notebook PC to which the Network PC Card is associat- ed is powered on.

•Make sure that your Network PC Card is configured on the same channel and with the same security options as with the other computers in the Infrastructure configuration.

Frequently Asked Questions

Can I run an application from a remote computer over the wireless net- work?

This will depend on whether or not the application is designed to be used over a network. Consult the application's user guide to determine if it supports oper- ation over a network.

Can I play computer games with other members of the wireless network?

Yes, as long as the game supports multiple players over a LAN (local area net- work). Refer to the game's user guide for more information.

What is IEEE 802.11 standard?

The IEEE 802.11 Wireless LAN standards subcommittee, which is formulating a standard for the industry. The objective is to enable wireless LAN hardware from different manufacturers to communicate.

What IEEE 802.11 features are supported?

The product supports the following IEEE 802.11 functions:

•CSMA/CA plus Acknowledge protocol

•Multi-Channel Roaming

•Automatic Rate Selection

•RTS/CTS feature

•Fragmentation

•Power Management

What is Ad-hoc?

An Ad-hoc wireless LAN is a group of computers, each with a WLAN adapter, connected as an independent wireless LAN. Ad hoc wireless LAN is applica- ble at a departmental scale for a branch or SOHO operation.

What is Infrastructure?

An integrated wireless and wired LAN is called an Infrastructure configura- tion. Infrastructure is applicable to enterprise scale for wireless access to cen- tral database, or wireless application for mobile workers.

PCI Adapter

What is Roaming?

Roaming is the ability of a portable computer user to communicate continu- ously while moving freely throughout an area greater than that covered by a sin- gle Access Point. Before using the roaming function, the workstation must make sure that it is the same channel number with the Access Point of dedicat- ed coverage area.

To achieve true seamless connectivity, the wireless LAN must incorporate a number of different functions. Each node and Access Point, for example, must always acknowledge receipt of each message. Each node must maintain contact with the wireless network even when not actually transmitting data. Achieving these functions simultaneously requires a dynamic RF networking technology that links Access Points and nodes. In such a system, the user’s end node under- takes a search for the best possible access to the system. First, it evaluates such factors as signal strength and quality, as well as the message load currently being carried by each Access Point and the distance of each Access Point to the wired backbone. Based on that information, the node next selects the right Access Point and registers its address. Communications between end node and host computer can then be transmitted up and down the backbone.

As the user moves on, the end nodes RF transmitter regularly checks the sys- tem to determine whether it is in touch with the original Access Point or whether it should seek a new one. When a node no longer receives acknowl- edgment from its original Access Point, it undertakes a new search. Upon find- ing a new Access Point, it then reregisters, and the communication process con- tinues.

What is BSS ID?

A specific Ad hoc LAN is called a Basic Service Set (BSS). Computers in a BSS must be configured with the same BSS ID.

What is ESS ID?

An Infrastructure configuration could also support roaming capability for mobile workers. More than one BSS can be configured as an Extended Service Set (ESS). Users within an ESS could Roam freely between BSSs while served as a continuous connection to the network wireless stations and Access Points within an ESS must be configured with the same ESS ID and the same radio channel.

WDT11 specifications

The Linksys WDT11 is a wireless bridge designed to extend connectivity and provide enhanced network performance in both home and office environments. As part of Linksys' renowned product line, the WDT11 stands out due to its unique features that cater to various networking needs.

One of the primary characteristics of the WDT11 is its ability to bridge wired and wireless networks seamlessly. This capability allows users to connect their existing wired devices, such as printers or desktop computers, to a wireless network without the need for extensive cabling. The device supports 802.11b wireless standards, ensuring a reliable connection with speeds up to 11 Mbps, which was impressive at the time of its release.

The WDT11 features a user-friendly interface that simplifies the setup process. With a straightforward configuration page, users can easily manage and customize their network settings. Additionally, the firmware can be updated to ensure the bridge maintains optimal performance and security over time.

Security is another crucial aspect of the WDT11. It supports Wired Equivalent Privacy (WEP) encryption, which helps to safeguard the network from unauthorized access. While WEP encryption is now considered outdated, the device’s support for WEP at the time provided a necessary level of security for wireless communications.

For optimal connectivity, the Linksys WDT11 is equipped with multiple antennae positioned for improved signal strength and range. This ensures that even devices located far from the wireless router can maintain a stable connection. The range of the WDT11 is suitable for medium-sized homes and small offices, making it a versatile option for various environments.

The device also incorporates Linksys’ Multi-Purpose Architecture (MPA), contributing to its flexibility and usability. This feature allows the WDT11 to function not only as a wireless bridge but also in different modes such as access point and client mode, accommodating various networking scenarios.

In summary, the Linksys WDT11 is a robust wireless bridge that enhances connectivity for both wired and wireless devices. With its ease of use, basic security features, and adaptable functionality, it represents a solid choice for users looking to expand their network capabilities. As technology continues to advance, the WDT11 remains a testament to Linksys' commitment to quality and innovative networking solutions.
