Introduction
The Fast-VNET USB (A) adapter based on Wireless Media Access
Controller is a network card with a rate of 1, 2, 5.5, and 11 Mbps operating in the ISM
band using Direct Sequence Spread Spectrum (DSSS) transmission implementing the
IEEE 802.11b standard. For this card c urrently provides Device Drivers for MS
Windows
and firmware upgrade of the cards. These tools, as well as the installation procedure for
the MS Windows 98/2000, and Windows Me operating systems are described in this
document.
To install the adapter and operate under an operating system two pieces of software are
needed. The first one is the driver, which prov ides the necessar y mechanisms to the
operating system in order to use the adapter as any other networking adapter. The
driver communicates with the firmware using exchange of commands (Set MIB, Get
MIB, Scan, Sync, etc.). The other piece of software needed is the code written on the
MAC chip, which is responsible for the interface with the driver, and for the implementation of the IEEE 802.11b functions.
®
98/2000, and Windows® Me. also provides tools for the configuration

Although similar in appearance, Windows 98/Me/2000 have different philosophies when
installing a new hardware.
Throughout this section it is assumed that you hav e a basic working knowl edge of Windows 98/Me/2000 and of how to install new network cards on them. However, in this
paragraph, some specific features of Windows 98/Me/2000 are briefly explained.
Windows 98/Me/2000 operating system supports the “Pl ug & Play ” feature. T hat means
that once you plug the Fast-VNET card for the very first time, the operating system will
detect the card and automatically i nstall the driv er assuming that you have already
installed the application utility.
Another feature is the “Hot Swapping”. With this feature, you can unplug and plug again
the card whenever you want.
During the installation, you may be prompted to load operating system files from the
Windows installation disk. Please have this disk handy.
You will need the Firmware and Software Tools CD provided with your Evaluation Kit.
Note:
