InstantWave High Speed was designed with a “Maximizing the convenience of networking” philosophy in mind. You will find InstantWave High Speed very easy to configure and use. This User’s Guide gives comprehensive instructions on installing and using the InstantWave High Speed USB Adapters, and also explains how to install and use the InstantWave High Speed Utility Program. InstantWave High Speed Family The InstantWave High Speed USB Adapters are part of the InstantWave High Speed family of easy to use high performance wireless communication products. The family products include: • InstantWave High Speed PC Card (NWH610) • InstantWave High Speed PCI Card (NWH630) • InstantWave High Speed Access Point (NWH660, NWH650) • InstantWave High Speed USB Adapter (NWH640) System Requirements Hardware Platform A station must be an x86 compatible PC with a USB interface. The minimum system configuration is the same as that required to run MS Windows (Windows 95OSR2, 98, NT 4.0, 2000). Software Environment The stations operate in conjunction with most of the MS Windows (Windows 95OSR2, 98, NT 4.0, 2000). InstantWave High Speed USB Adapter v Glossary Wireless Network In the IEEE 802.11 definition, a wireless network is classified as an Ad-Hoc network or an Infrastructure network. Ad-Hoc Network An Ad-Hoc network is formed by a number of wireless stations (without an Access Point) communicating via radio waves. For the users, the shared resources on the wireless network appear exactly as they would on a regular wired network. The wireless operation of the network is totally transparent. Figure 1 depicts a typical Ad-Hoc network scenario. Wireless Stations Figure 1. An Ad-Hoc Network Infrastructure Network An Infrastructure network is formed by several stations and one Access Point (AP), with the stations within range of the AP. Figure 2 depicts a typical Infrastructure network topology. Wired Computers Server Access Point Wireless Computers (USB Adapter) Figure 2. An Infrastructure Network 2 InstantWave High Speed USB Adapter Group ID/BSSID A Group ID (the 802.11 standard uses the term BSSID) is the ID of a wireless cell. A wireless cell is usually made up of stations in an area that the radio signal can comfortably cover. In other words, any wireless station in the cell can communicate with any other within reach of the radio signal (Figure 3). Access Point Wireless Stations Figure 3. A Wireless Cell (Group) Domain Name/ESSID A domain is usually defined by the network administrator as a segment/subnet of a large network and may be made up of overlapping wireless cells. Wireless nodes can roam freely within the same domain without disconnecting from the network. Figure 4 depicts a common wireless network setup. Server Access Point Figure 4. Roaming in the Same Domain Roaming The convenience of a mobile PC is the ability to move freely. The concept is similar to that of a cellular phone moving from one base station to another. InstantWave High Speed offers built-in high performance seamless roaming capabilities. Carrier Set InstantWave products use the unlicensed ISM (Industrial, Scientific, Medical) band to communicate through radio waves. Different countries offer different radio frequencies to be used as the ISM band. There are four frequency bands defined by 802.11: Japan (2.471GHz – 2.497 GHz), USA, Extended Japan, Canada, and Europe (2.4 GHz – 2.4835 GHz), Spain (2.445 GHz – 2.475 GHz), France (2.4465 GHz – 2.4835 GHz). If a user wants to use InstantWave High Speed in a country not listed above, he/she needs to check with their government’s regulating body to InstantWave High Speed USB Adapter 3 find the correct frequency band to use. All InstantWave High Speed products are supplied preset to the country of sale’s frequency band. Access Point An Access Point (AP) provides a transparent bridged connection between a wired network and a wireless network and allows wireless stations to communicate with devices attached to a wired network. It manages the flow of data packets from the wired LAN to the Wireless LAN and vice versa. 4 InstantWave High Speed USB Adapter Getting Started This section explains how to quickly setup a wireless station.

Figure 23. Configuration • • Network Type - The 802.11 Wireless Specifications allow for two types of network, Infrastructure or Ad-Hoc (see the Glossary on page 2). Infrastructure is used when networking with an Access Point. The default setting is Infrastructure Domain Name - Stations and APs in the same group must use the same domain name. This field is defined in the 802.11 Wireless Standard as ESSID 18 InstantWave High Speed USB Adapter (Extended Service Set ID). Having the same Domain Name allows all wireless nodes in the same Domain (or Cell) to communicate with each other. The default setting is Wireless. InstantWave High Speed USB Adapter 19 • Transmission Rate – The transmission rate at which the data packets are transmitted by the client or AP. You can set this to Auto select 1 or 2 Mbps, Fixed 1 Mbps, Fixed 2 Mbps, Fixed 5.5 Mbps, Fixed 11Mbps or Full Auto(1 to 11 Mbps). • Carrier Set - This is preset to the U.S.A., Canada, Europe, Spain, France, or Japan depending on where the product is sold. The parameter shown indicates which Radio Frequency (RF) 802.11 specification is currently in use in the adapter(read only) • Channel – You can change the channel number. In case of the Ad-hoc Network Mode, the change in the channel number is effective. In case of the Infrastructure Mode, changing the channel number is of no concern as the channel is scanned automatically. The client will look for AP with the same ESSID, and automatically associated with the AP. Channels supported on every carrier set: Channel Center FCC/ Number Frequency Canada (MHz) ETSI Spain France Japan 2412 2417 2422 2427 2432 2437 2442 2447 2452 10 2457 11 2462 12 2467 13 2472 14 2484 Important: 20 InstantWave High Speed USB Adapter In a multiple cell network topology, overlapping and/or adjacent cells using different channels can operate simultaneously without interference if the frequency distance between the center frequencies is at least 30MHz. For example channel 1, 7 and 13 are non-overlapping frequency channels. • Power Saving – Power saving mode enable and disable Click OK to close the window. A pop-up screen will ask if you wish to reboot your computer to make the changes effective. Click Yes • Enable Roaming - Roaming can be turned on or off. When roaming is enabled, the station is allowed to roam to another Access Point in the same domain when the radio signal quality of the currently connected AP is below an acceptable level Advanced Information Click the Advanced Information tab to view the Adapter Properties (Figure 24). Figure 24. Wireless Adapter Properties The window is divided into three sections as described below: • Basic Information - This section contains the manufacturer’s name and the InstantWave High Speed MAC firmware version number.

Figure 25. Wireless Adapter Link Properties • State - Link State explains whether the client is connected to ESSID or not. It also shows the identification MAC address of the ESS to which this is connected currently. • Current Channel – Channel number is the channel avalable for the communication between the clients and AP or between the clients only. In case of the Infrastructure Network Mode, the channel number is scanned automatically. Need not to worry about setting the channel number. While in case of the Ad-hoc Network Mode, the channel number is set by the clent and can be changed by the client later. • Current Tx Rate - Shows the current transmission rate on the adapter. • Signal Strength - Displays the measure of the signal strength level. • Rescan – The client will rescan the access point with the same domain name on difference channel. WEP 22 InstantWave High Speed USB Adapter Click the Encryption tab to view the Adapter WEP Properties (Figure 24). Figure 26. WEP Security • Use WEP - The WEP stands for Wired Equivalent Privacy. WEP is an encryption scheme that provides the secure wireless data communications to the users. WEP uses a 40-bits key to control the network access. In order to decode the data transmission, each wireless client on the network must use the identical 40-bits key. • WEP Key Generation - There are two ways of generating the WEP key. The first is by entering any text in the Passphrase. And click on Generate. It will generate four WEP keys as Key 1, Key 2, Key 3 and Key 4. You can select any key for the security. If you do not select any key, key 1 is selected, as it is default key. Then click on Write and it will update the registry and driver. Another WEP key generation method is by inserting the key values directly from the keyboard. And click on the write to update driver and Registry. Select the Key InstantWave High Speed USB Adapter 23 number and use Key for accessing the Access Point. If the Key is not entered correctly, a client cannot access the resources. As the wireless channel is more prone to the illegal access, WEP provides users safe access. If the WEP key is enable on the AP, all client should be use the same WEP key with AP. Otherwise the client can not be association with the AP Troubleshooting Should a problem be encountered using the wireless adapter that cannot be resolved using the ‘Troubleshooting’ section of this manual, click the Troubleshooting tab (Figure 27). A diagnosis program will run and report the message. Send the diagnostic message together with a description of the symptoms to NDC’s technical support via email. Figure 27. Troubleshooting 24 InstantWave High Speed USB Adapter Network Watcher (Infrastructure) In an Infrastructure network, Network Watcher scans for all existing wireless cells in range and displays the AP names, the MAC address, the Domain Name, the Signal Strength, the number of stations currently connected to each AP, and the connection status. When Network Watcher is run, the program first reads and displays information stored in the database. The signal strength entry shows either Green (strong signal), or Yellow (average signal). The information is not dynamically updated. To refresh the data click the Scan button. Network Watcher also gives users the option of selecting an Access Point to join with manually. Figure 28. Network Watcher (Infrastructure) Scan Click Scan to obtain and display updated data. You may need to wait a short time depending on the number of wireless cell replies received. Join Selecting one of the APs from the list will enable the Join command. The Join command allows you to manually connect to a specific AP. If joining cannot be accomplished within 20 seconds (possibly due to an AP that has gone off the air since the data was last refreshed, to RF interference, or a busy AP), the operation will fail. If this happens, you may try joining with the same AP again, or select another AP to join. Network Watcher (Ad-Hoc) On an Ad-Hoc network, Network Watcher displays all the wireless nodes (with their Computer Name and Node Address (MAC ID)s) that are currently connected in the same Group as this station (Figure 29). The inactive timer counts the period that there is no traffic between it and the other connected stations. Figure 29. Network Watcher (Ad-Hoc) InstantWave High Speed USB Adapter 25 Refresh Click Refresh to obtain and display updated data. You may need to wait a short time depending on the number of replies received. Signal Quality Indicator Signal Quality Indicator dynamically displays the present radio signal quality (Figure 30). The quality level is indicated by colors. Green means the signal is good, Yellow indicates the signal is fair, Red denotes the signal is poor. When the signal color reaches the yellow to red border, the station will start to roam if roaming is enabled. Figure 30. Signal Quality Indicator Throughput Monitor This item enables users to monitor the throughput (transmitted and received bits) of the wireless station (Figure 31). Figure 31.
