vendor. The ZoomAir Wireless LAN Card adheres to the IEEE 802.11 DSSS specification to ensure interoperability with other 802.11 DSSS wireless LAN systems. Why Wireless? With a wireless LAN product like ZoomAir, you no longer have to choose between the inconvenience and expense of running wires and the expense of older, nonstandard wireless devices. -
Page 7: How Does The Zoomair Work
How Does the ZoomAir Work? The radio transmitter in the ZoomAir Card sends a radio signal in the 2.4 GHz (gigahertz, or billion-cycles-per-second) part of the radio spectrum. This is one of the “ISM” bands that are reserved for general use and require no license to use. (For instance, most cordless phones also operate in a different ISM band.) When a computer adds data to this radio signal, it modifies, or “modulates”... -

Page 13: Planning Your Wireless Network
Planning Your Wireless Network The installation of any new computer hardware or software is more likely to be successful with a little planning. This chapter covers the following: • Simple Ad-Hoc Network • Infrastructure All-Wireless Network • Infrastructure Network with Access Point to a Wired LAN Simple Ad-Hoc Network If you are setting up an all-wireless ad-hoc network in a home or small office, there is not much planning to do. -

written, wireless bridging between Access Points was not sup- ported for all-wireless networks. Infrastructure Network with Access Point to a Wired LAN If you are installing an infrastructure wireless network to connect to a wired LAN, you will need one Access Point for each 100 to 300 linear feet (about 30 to 90 meters) in typical indoor environ- ments;... -
Page 15: Access Point(S) First
The advantage of this plan is that you install the simplest ad-hoc network first and troubleshoot it. It also makes the most sense if you have been operating an ad-hoc wireless network for a while and want to join it to a wired network later. Access Point(s) First Install your Access Point(s) first, according to the instructions in the ZoomAir Access Point Software Manual. - Page 16 Another consideration to keep in mind for both ad-hoc and infra- structure networks is that you may want to keep one or more computers in a fixed location and running all the time: • Any computer with a resource that must be regularly shared, such as a printer, a drive or file folder, or a modem.

Page 32: Next Steps
Next Steps Your installation is now complete. If you are installing a wireless ad-hoc network, all of your network clients should be connected to each other. The next step, for both ad-hoc and infrastructure networks, is for each client to determine whether it will share its printer, if any, and its files. -
Page 33: Sharing Printers And Files
Sharing Printers and Files The printer connected to any network member’s computer, and the files on its hard drive, must be explicitly shared so that other network members can use them. This sharing is established through the Windows operating system on each computer. - Page 34 Click on the Shared As radio button. You can change the name in the Share Name space if you want to. You can add a comment, which will appear in other network members’ lists in Network Neighborhood. If you want everyone on the network to have access to this printer, you can leave Password blank.
-
Page 35: Files
Important: Network members who want to share another member’s printer must install the printer driver for that printer on their own computer. Consult the Windows Help file and the printer’s own documentation for details. Files When you specify a folder or an entire drive to be shared, other members of your network will have access to the files inside it. -

print this file”; “Please turn on your computer so I can read your report.” In larger organizations, you may find it desirable to keep one or more computers and printers running all the time, or at least dur- ing business hours. The computer with a shared printer is certainly a candidate. -
Page 38: Changing Security Settings
Changing Security Settings A wireless network installed in a home or a small, stand-alone business is probably as secure it needs to be. To eavesdrop on your network, an outsider would have to install identical ZoomAir wireless equipment, using only the default settings, and be well within 300 feet of your network. - Page 39 Click on the Configuration tab. The following dialog box will display: 4 Changing Security Settings...
- Page 40 In the SSID space, type in a group name that will be shared by every member of your wireless network. This identifier must be the same for all computers that will be in the same wireless network. It is case-sensitive. Members of your network should regard the SSID as a password and keep it secret.
-
Page 41: Wired Equivalent Privacy (Wep)
Wired Equivalent Privacy (WEP) Although your ZoomAir wireless LAN is fairly secure using a unique SSID, you may desire an additional measure of security. The IEEE 802.11 standard includes provisions for software en- cryption called Wired Equivalent Privacy, or WEP. WEP is a method of scrambling data before it is sent and reconstructing it as it is received. - Page 42 • Mandatory—Members for which WEP is enabled will have access only to other members with WEP enabled. • Dynamic—Intended for infrastructure networks using an Access Point. Do not use it for an ad-hoc network. When Dynamic mode is in use at an Access Point, the Access Point can communicate with either Mandatory or Dis- abled WEP members.

Page 44: Advanced Settings
Advanced Settings The ZoomAir PC Card is intended to be installed without your having to customize its settings. If you accept the default settings for each ZoomAir PC Card you install, you should have a functioning wireless ad-hoc network with no further work. If security is a concern, the few changes you make (following the instructions in Chapter 4) should be all that you need. - Page 45 This is the first screen of the configuration utility. You may have already seen this screen if you changed the security set- tings (see Chapter 4). Link Info tells you whether this PC is linked to another PC on the ZoomAir network and gives some information about that link.

Page 50: Solving Common Problems
Solving Common Problems The most common problems with wireless networks are likely to involve mis-matches between how the ZoomAir PC Cards are set up: Protocols, SSID, Workgroup name, and so on. Users should also be sure they have set up sharing correctly and— perhaps the most obvious and easiest to miss—that the networked computers are running. - Page 51 The network seems to be set up and operating correctly, but some members do not show any shared folders or printers. • Each member of the network controls what can be shared. If a member has not set up a folder or printer for sharing, nothing will show up in Network Neighborhood beyond the icon for his or her computer.
- Page 52 • If data transfers with one or more of the network members is noticeably slower than the rest, that member may be close to the limit of its effective range. Data sent over networks is bro- ken down into smaller units called packets. The networking software checks the packets in various ways and may request that missing or damaged packets be re-sent.
- Page 53 Your wireless LAN’s performance has been fine until re- cently; then performance deteriorated rapidly. • Double-check all installations and settings. Some members may have been experimenting with the network or may have installed communications software that affected the network settings. •...

Searching the computer for new hardware may take a few minutes. You will eventually see the message Windows has finished detecting hardware and is ready to install sup- port for all detected devices. • If you do not see this message, it is likely that the card was not installed properly. - Page 58 Scroll down to the Pcmcia entry and click on it to highlight it: Click on Startup. The Device dialog box will display: Click on Automatic; then click on OK. Back in the Devices dialog box, click on HW Profiles. A De- vice dialog box will display.
