Introduction
Congratulations on choosing an InstantWave wireless product. This guide gives
comprehensive instructions on installing and using the InstantWave NWH660
11-Mbps Wireless Access Point (AP), and also explains how to install and use the
InstantWave Management System (IWMS) software.

InstantWave Wireless LAN Products
InstantWave wireless products provide an integrated solution to your wireless
networking requirements.
• For indoor applications: Access points, wireless workgroup bridges, wireless
ethernet clients, and wireless adapters with various bus interfaces (PCMCIA,
USB, and PCI).
• For outdoor applications: The InstantWave building-to-building bridge
connects two independent Ethernet LANs via a radio link, making expensive
outdoor cabling unnecessary. High-gain directional antennas provide the
greatest possible transmission range.
• Management tools: InstantWave products support the industry-standard
Simple Network Management Protocol (SNMP) and the SNMP-based
InstantWave Management System (IWMS), a powerful set of utilities for
managing not only devices but whole networks and internetworks.

IWMS — The InstantWave Management System
IWMS is a powerful network management system that is fully compatible with the
industry-standard Simple Network Management Protocol (SNMP). It features:
• Automatic discovery of all InstantWave devices that are configured within
the same subnet
• Individual and batch-mode remote management of InstantWave devices,
including Multi-Monitor, Batch-Upgrade, Batch-Reset, and
Batch-LoadDefault functions. Batch-mode operation is ideal when deploying
multiple InstantWave products.
• A friendly end-user interface with a consistent look and feel.
Automatic Discovery of InstantWave Devices
A powerful auto-discovery algorithm is built into the InstantWave Network
Management System. With a simple click on the Auto Discovery icon, all
InstantWave devices within the subnet will be discovered. This discovery feature is
based on the following techniques:
• DHCP client and IP recovery: The NWH660 has a built-in DHCP client, and
will request an IP address from a DHCP server so that SNMP management
can be carried out. Should there be a failure of the DHCP server, the
NWH660 will auto-assign itself an IP address (see next) and then
automatically negotiate for a new IP address when the server recovers.
• Auto-IP: When the NWH660 cannot get an IP address from the DHCP server,
it will auto-assign itself an IP address of 169.254.x.x and a subnet mask of
255.255.0.0. A Windows-based system configured as a DHCP client will
follow the same algorithm to assign itself an IP address in the same subnet.
When the DHCP server comes back on line, users may need to renew their
