Introduction
Congratulations on choosing one of NDC’s InstantWave High Rate wireless
networking products. InstantWave High Rate was one of the first IEEE 802.11b
wireless standard compliant products in the industry and was designed to maximize
the convenience of networking. You will find InstantWave High Rate products
very easy to setup and use.
The User’s Guide gives comprehensive instructions on installing and using the
InstantWave NWH650 High Rate Access Point (AP). The AP provides a
transparent bridged connection between a wired network and a wireless network
and allows your wireless stations to communicate with devices attached to your
wired network. It manages the flow of data packets from the wired LAN to the
wireless LAN, and vice versa. The Access Point Management System (APMS)
performs wireless network configuration management and diagnostic functions.
InstantWave High Rate Family
The InstantWave NWH650 High Rate Access Point is part of a family of easy to
use high performance wireless communication products. The family products
include:
• InstantWave High Rate Access Points (NWH650, NWH660)
• InstantWave High Rate PCI Card (NWH630)
• InstantWave High Rate PC Card (NWH610)
System Requirements
System requirements to install and operate the InstantWave High Rate Access
Point are:
• One PC
• One 802.11b compliant card
• An Ethernet drop (UTP)
• An RS-232 cable (only used when configuration of the AP’s network
properties is necessary)
• A PC (only used when configuration of the AP’s network properties is
necessary)
Cabling
Connecting the Access Point (AP) to an Ethernet network requires an Unshielded
Twisted-Pair cable. The AP fits into the network just as any other node would do.
An LED will light to indicate a connection. The cable length should follow
Ethernet standards in each case.
InstantWave High Rate 11Mbps Access Point 1
How to Use this Guide
InstantWave High Rate is extremely versatile in providing varying levels of
network management. For Small Office/Home Office users, setup and
configuration is a quick, four-step process. The Access Point Hardware
Installation section, on page 8, provides simple instructions to get your network up
and running within minutes. Go to the Access Point Hardware Installation section
if your network will meet the following criteria:
•
•
You will accept all default values
Your network will have only one Access Point
The AP COMFig tool, see page 11, permits AP configuration from a PC via a
COM port connection. The program enables the user to change the default Access
Point IP configuration settings before introducing a new AP to an already
established wireless network.
Before using the setup tool, you should read through the next section ‘Planning
Your Network’, in order to get the best possible performance from your
InstantWave High Rate wireless network.
2 InstantWave High Rate 11Mbps Access Point
Planning Your Network
Infrastructure Network Types
An Infrastructure network is formed by several stations and one or more Access
Points (APs), with the stations within a set distance from the AP. Figure 1 depicts
a typical Infrastructure network topology.
There are three infrastructure network setups that are commonly used. It is a good
idea to understand the possible network setups and configuration requirements
before planning your wireless network.
Type 1.
The simplest wireless infrastructure network is composed of one
Access Point (AP) and a few wireless Stations communicating via
radio waves (Figure 1). This setup enables mobile stations to
communicate with each other. The main benefit of this type of
network is to extend the range of the network. If an AP is placed
between the stations, the radio transmission distance is effectively
doubled since Wireless Computer-1 can talk to Wireless Computer-2
through the AP. The drawback of this configuration is that the
effective bandwidth is halved since all communication is relayed by
the AP.

Computer-2
Figure 1. Simple Wireless Infrastructure Network
Type 2.
The next simplest wireless network is very similar to the Type 1
network. This time the AP is connected to a wired Ethernet network
as a node. In this configuration the AP is effectively performing as a
bridge between the wired Ethernet and the wireless networks (Figure
2).
Wireless users have the same access to the network resources as they
would have if they were wired. This type of network is usually used
to extend an existing network into a difficult to wire or a roaming
environment.

To increase bandwidth in order to boost overall network performance
To extend the coverage range
Any other type of configuration is usually a mix of these commonly used types.

Planning an Infrastructure Network
This section explains some of the things you need to consider in planning an
Infrastructure network. Setting up is a two step process.
1.
2.
Install and configure the InstantWave High Rate products
Decide the best physical location of the InstantWave High Rate products so as
to optimize performance
The following sections give quick guidelines for these two steps. Before we go
into detail, the network planner should first decide whether to have a single AP
wireless network or a multiple APs network.
Single AP Installation
If you are setting up a simple network with only one AP and a few Stations (a Type
1 or Type 2 network configuration as described in Infrastructure Network, page 3),
the installation can be performed painlessly. All you need to do is make sure the
AP and all the wireless Stations hold the same ‘Domain Name’ in their
configuration.
Adding a new Station to an existing Infrastructure network is easy. Again, all you
need to do is to set the newly added Station’s ‘Domain Name’ to the same as that
of the AP’s.
Multiple AP Installation
Install multiple APs in the same network (or Domain) with an overlapping signal
(Figure 3)
•
•
Use the same Domain Name
Enable the roaming function in the Station if roaming is required
Note: A Station will automatically connect to whichever AP in the same domain is
offering the best signal
InstantWave High Rate 11Mbps Access Point 5
Roaming
InstantWave High Rate products are equipped with seamless roaming capabilities.
Roaming is necessary to prevent mobile Stations from being disconnected from the
network as they move around.
InstantWave High Rate is designed to allow wireless Stations to roam freely within
an infrastructure domain composed of multiple APs with overlapping signal
coverage (as in the Type-3 network configuration described in the previous
section). For example, roaming enables Station-1 to move from the AP-1 signal
coverage area to the AP-2 signal coverage area without disconnecting from the
network. The handover is achieved transparently; the Station-1 user would not
realize he had moved from AP-1 to AP-2.
The requirements for a roaming environment are:
a)
Multiple APs with overlapping signal coverage (see Multiple AP
Installation, page 5)
b) The APs must be configured to have the same Domain name (see AP
COMFig/Service, page 12)
c) The mobile Stations must have the same Domain name as that of the APs
d) *It is advisable that APs on different TCP/IP subnets be given different
Domain names to avoid roaming confusion (see AP COMFig/Service,
page 12)
Note: *If you want to move your mobile PC between different APs without
terminating the existing networking link, you need to enable the roaming
function on the Mobile Station. The APs that a Mobile Station will roam to
must also be configured with the same domain name. If a Station detects
that the signal quality with the current linked AP is weak, it will search for
an AP in the same domain with a better signal quality and automatically
establish a new connection with it. When a Station is roaming, it will
always use the same IP address. The TCP/IP router will not route
information packets to a Mobile Station if it re-associates with a AP that is
in a different TCP/IP subnet. In other words, if your network consists of two
subnets connected by a router, a Mobile Station may roam to a different
subnet with the same domain name and then fail to communicate with other
network devices via TCP/IP. To avoid running into such an awkward
situation, you must assign different domain names to different TCP/IP
subnets.

Access Point Placement Guidelines
A characteristic of radio communication is the interference problem. Radio is
receptive to interference. Therefore, the more interference you can avoid, the
better performance you will get from wireless products. The following section
describes how the InstantWave High Rate AP should be placed to reduce possible
interference.
A few tips to mention that are particularly significant in a radio wave
communications system:
1.
Radio waves reflect or refract from buildings, walls, metal furniture, or other
objects. This could result in performance degradation due to the fluctuation of
the received signal.
2.
Microwave ovens use the 2.45 GHz frequency band. InstantWave High Rate
also functions in the 2.4 ~ 2.5 GHz band, and therefore shares some of the
band with microwave ovens. This means that when a nearby microwave oven
is in use, it may interfere with InstantWave High Rate, resulting in
performance degradation on the wireless network.
Placing For Performance
For the best performance, it is advisable that users follow the guidelines below in
placing the product:
•
•
•
Place the AP as high as possible, in as open an area as possible
Avoid placing the AP close to metal objects (e.g., file cabinets, metal cubicles,
etc.)
Keep APs and Stations as far away as possible from microwave ovens (10
meters min. is advisable)
Placement Tools
InstantWave High Rate includes a Station utility program to help users find the
best location in which to place the AP relative to the location of the Stations.

1, 7, and 13 are non-overlapping frequency channels.
After making any changes, click the Apply button to make the changes effective
immediately, without closing the dialog box, or click OK to accept the changes and
close the box.
Encryption:
Data encryption provides more secure wireless data communications. Click the
Encryption tab to setup/change the security settings (Figure 11). The default is
Disabled and initially the keys section will be blank.
InstantWave High Rate 11Mbps Access Point 15
Figure 11. Configuration/Encryption
The dropdown Method box lists three options:
1.
Disabled (default) - Disable data encryption
2.
40-bit WEP - Enable use of 40-bit WEP
3.
128-bit WEP - Enable use of 128-bit WEP
Key Generation - There are two ways to generate a security key.
The first is by entering any text in the Passphrase field. Click the Generate button.
For 40-bit WEP, it will generate four keys, Key 1, Key 2, Key 3, and Key 4. Select
a key number from the dropdown list of the Default Key box. If you do not
manually select a key, key 1 will be selected. For 128-bit WEP, only one key will
be generated. Click Apply.
Another WEP key generation method is to insert the key values directly from the
keyboard. Enter your own key into one of the Key 1~4 fields. Select that field
number in the Default Key field. If the WEP key is enabled on the AP, all clients
must use the same WEP key. Click OK.
Note: Most wireless connection problems arise from improper WEP settings so
make sure all APs and wireless stations use the same settings.
16 InstantWave High Rate 11Mbps Access Point
IP:
Note: These SNMP related settings are only useful for network management and
remote configuration (APMS). For proper wireless connections, these
settings don’t have to be changed.
From the IP card (Figure 12) you may view or modify the Access Point’s TCP/IP
address, configure its subnet mask, or add a default gateway (see the note below).
Note: An AP will directly transfer SNMP respond packets (confirmation packets)
to an APMS PC if it is within the same LAN (the same subnet mask). If an
SNMP respond packet from an AP is destined for an APMS PC on another
LAN, then the SNMP respond packet needs to go through a router-gateway.
The default gateway is the path to that router. If you set the correct default
gateway, then you can use an APMS manager (i.e. a PC running APMS)
physically located in a different subnet to manage this AP.
IP Address
InstantWave High Rate Access Points are delivered with
a default IP of 192.168.1.1
Consult your network administrator for exact settings.
Subnet Mask
InstantWave High Rate Access Points are delivered with
a default subnet mask of 255.255.255.0
Consult your network administrator for exact settings.
Default Gateway
Enter the default gateway address here (if required)
If you wish to change the defaults, set each AP to its new IP address before
introducing it to the open network. All APs within the same network must have
the same TCP/IP subnet address.

18 InstantWave High Rate 11Mbps Access Point
Filter:
The next tab on the dialog box is Filter (Figure 13). This is a one-way protocol
filtering mechanism that prevents the AP from transmitting specified protocols
from a wired Ethernet LAN into the wireless LAN. If you do not require particular
protocols on the wireless part of your network, you can save bandwidth by
enabling the protocol filter.
Figure 13. Configuration/Filter
From the Filter card, some, all, or none of the protocols listed may be selected for
filtering out:
•
IP Protocol
•
IPX Protocol
•
NetBEUI Protocol
•
AppleTalk Protocol
•
Other Protocols
•
Internet Multicast Frames
After selecting a protocol to be filtered, click the Apply button to make the changes
effective immediately, without closing the dialog box, or click OK to accept the
changes and close the box.
InstantWave High Rate 11Mbps Access Point 19
SNMP Access Control:
SNMP Access Control is the next tab on the box (Figure 14).
Figure 14. Configuration/SNMP Access Control
The AP’s access control is managed by a control table on the AP. The first time
this box is opened, the table will be empty. This means that there are no
restrictions on who can access and reconfigure the AP and any user may modify
the AP’s operation. To avoid chaos on the network, access to the AP configuration
should be restricted to only those for whom it is necessary.
Click Add to open the New Entry dialog box (Figure 15).

Using the Access Point Management
System (Advanced Configuration and
Management)
Once the AP is connected to an Ethernet network, a network administrator can
connect to it from any PC on the same network via the Access Point Management
System (APMS) utility.
The APMS utility is a Windows-based SNMP management tool, allowing network
administrators to remotely configure and monitor APs through an Ethernet or
wireless connection. The APMS management tool is intended for performing fullblown wireless network configuration and management. To launch the APMS
utility, click Start/Programs/InstantWave High Rate AP/AP Management
System.
The program opens with the InstantWave Network Management System screen.
You may now configure and monitor the APs in the wireless network from the
Access Point Host Table.
The APMS Host Table is equivalent to an address book of Access Points (APs).
The first time the program starts the screen will be blank.
Figure 21. Network Management System-1
At least one AP must be entered in the table to allow the local wireless adapter to
connect to it. The next section explains how to add to/edit the Host Table.
Note: Right-clicking anywhere in the main window provides fast access to most of
the main-menu items
To add an AP to the Host Table, use one of the methods below:
1.
Load an existing Host Table by clicking Import Host Table from the File
menu. You may load APs you have previously configured with the AP
COMFig tool.
InstantWave High Rate 11Mbps Access Point 25
Figure 22. Network Management System-2
2.
Click the AP main menu item to open its sub-menu and then click Create New
AP (Figure 23).
Figure 23. Network Management System-3
Input the AP’s IP address and its community string (this string will be used for
SNMP access control). When the information has been entered, the OK button will
become active. Click OK. Repeat the process to add more APs. To delete an AP
icon from the window, first select it and then press the Delete key.
Connecting to an AP
Once a Host Table has been created, a connection can be made by double-clicking
an AP’s icon in the Host Table. Alternatively, click AP on the main menu and then
click Connect AP.
In the Connect AP dialog box, click on the down arrow of the AP entry field to
open the dropdown AP list. Select an AP and complete the selection by clicking
OK. If the connection is successful the current connected AP’s IP address will
appear on the title bar.
AP Properties
After connecting, right-clicking on a connected AP’s icon will open a menu. Click
Properties to open the AP Properties screen (Figure 24).
26 InstantWave High Rate 11Mbps Access Point
Figure 24. AP Properties
Here you may modify the IP address and Community string. Changes made here
will be immediately effective.
If the connection attempt was unsuccessful, a message box will appear informing
you that the request had no response. Click OK to close the message box and
return to the main screen. Go through the procedure again to retry. If you cannot
connect to the AP after three attempts, check that the AP information has been
correctly entered in the Host Table and that the Access Point (AP) is functioning.
Managing Configurations
Config
If the AP selection is successful, the Config and View main menu items will be

Figure 26. AP Settings/IP
IP:
From the IP card you may view or modify the Access Point’s TCP/IP address,
configure its subnet mask, or add a default gateway (see the following note).
Note: An AP will transfer SNMP respond packets (confirmation packets) to its
APMS PC directly if it is within the same LAN (the same subnet mask). If an
SNMP respond packet from an AP is destined for an APMS PC on another
28 InstantWave High Rate 11Mbps Access Point
LAN, then the SNMP respond packet needs to go through a router-gateway.
The default gateway is the path to that router. If you set the correct default
gateway, then you can use a PC running APMS located on a different subnet
to manage this AP.
All InstantWave Access Points are delivered with a default IP of 192.168.1.1 and a
default subnet mask of 255.255.255.0. If you wish to change the defaults, set each
AP to its new IP address before introducing it to the open network.
Consult your network administrator for exact settings.
After making changes, click OK to return to the Config sub-menu and click the
Reset AP menu item to make the changes effective.
Filter:
The second tab on the box is Filter (Figure 27). This is a one-way protocol
filtering mechanism that prevents the AP from transmitting specified protocols
from the wired Ethernet LAN into the wireless zone. If you do not require
particular protocols on the wireless part of your network, you can save bandwidth
by enabling the protocol filter.
Figure 27. Filter (APMS)
InstantWave High Rate 11Mbps Access Point 29
From the Filter card, some, all, or none of the protocols listed may be selected for
filtering out:
•
IP protocol
•
IPX protocol
•
NetBEUI protocol
•
AppleTalk protocol
•
Other protocols
•
Internet Multicast Frames
Selecting a protocol to be filtered will activate the AP’s protocol filtering
immediately on clicking OK. Clicking Reset AP is not required. If, after filtering a
protocol, your network is not functioning as before, it’s likely the protocol is
required on the network and you should disable the filter for that protocol.
TFTP:
The Access Point supports remote firmware upgrades using TFTP (Trivial File
Transfer Protocol). You may customize TFTP services with the following options:
Figure 28. AP Setting/TFTP
30 InstantWave High Rate 11Mbps Access Point
Private Transfer:
TFTP currently has no provisions for user authentication. We suggest you keep the
‘Private Transfer’ option checked in order to prevent anyone other than the
network administrator using the APMS program to upgrade the AP firmware. If
you want to use a third party TFTP tool to upgrade the AP firmware, this option
should be disabled.
Timeout:
Specifies the number of seconds TFTP waits to make sure that the sender has
completed the transmission. The range is from 3 to 255 seconds.
SNMP Access Control:
SNMP Access Control is the next tab on the box (Figure 29). SNMP access
control is managed by a control table on the AP.
Figure 29. AP Setting/SNMP Access Control
The first time this box is opened, the table will be empty. This means that there are
no restrictions on who can access and reconfigure the AP and any user may modify
the AP’s operation. Access to the AP configuration should be restricted to only
those for whom it is absolutely necessary. First enter your IP address and then set
your own access rights to Read/Write (see the note below).
InstantWave High Rate 11Mbps Access Point 31
Note: Do not set all the stations in the Access Control table to Read. Once this is
set and enabled, it will be difficult to modify the AP. Should this situation
occur, use the AP COMFig utility to re-set the configuration.
Two levels of access are available. To set access rights, enter a station’s IP address
and community string (the community string must be the same as the AP’s in the
Host Table of the APMS manager terminal, i.e. the PC running APMS) and choose
Read or Read/Write.
Read
Read-only rights. The user may read everything

Suggested Solutions
1. Make sure the power adapter is firmly connected to
the power outlet and the AP power connector.
The InstantWave HR
APMS utility cannot
detect an InstantWave
HR AP on the same
network.
1. Make sure the AP is powered on and connected to
an Ethernet work.
Check the IP addresses assigned to the AP and APMS
terminal PC. They should be in the same subnet and
unique. For example, if the AP’s IP address is
192.168.1.5 with a mask of 255.255.255.0, then the
PC’s IP address should be 192.168.1.x with a mask of
255.255.255.0. Consult your network administrator
for exact settings.
The AP powers up, but Make sure:
