The SMC2632W V.2 can be configured as:
Ad hoc - for small groups that only communicate with each other
Infrastructure - for wireless LANs Network Topologies Ad Hoc Wireless LAN An ad hoc wireless LAN consists of a group of computers, each equipped with one wireless adapter, connected via radio signals as an independent wireless LAN. Computers in a specific ad hoc wireless LAN must therefore be configured to the same radio channel. An ad hoc wireless LAN can be used in a SOHO or temporary environment. PC with Wireless PCI Adapter Ad Hoc Wireless LAN Notebook with Wireless USB Adapter Notebook with Wireless PC Card 14 NETWORK TOPOLOGIES Infrastructure Wireless LAN The SMC2655W access point can also provide wireless workstations with access to a wired LAN. An integrated wired and wireless LAN is called an infrastructure configuration. A Basic Service Set (BSS) consists of a group of wireless PC users, and an access point that is directly connected to the wired LAN. Each wireless PC in this BSS can talk to any computer in its wireless group via a radio link, or access other computers or network resources in the wired LAN infrastructure via the access point. The infrastructure configuration not only extends the accessibility of wireless PCs to the wired LAN, but also extends the effective wireless transmission range for wireless PCs by passing their signal through one or more access points. A wireless infrastructure can be used for access to a central database, or for connection between mobile workers, as shown in the following figure. Wired LAN Extension to Wireless Adapters File Server Desktop PC Switch Notebook with Wireless PC Card Adapter Access Point PC with Wireless PC I Adapter 15 NETWORK CONFIGURATION AND PLANNING Setting the Communication Domain Stationary Wireless PCs The Basic Service Set (BSS) is the communication domain for each access point. For wireless PCs that do not need to support roaming, set the domain identifier (SSID) for the wireless card to the SSID of the access point you want to connect to. Check with your administrator for the SSID of the access point you should connect to. Roaming Wireless PCs A wireless infrastructure can also support roaming for mobile workers. More than one access point can be configured to create an Extended Service Set (ESS). By placing the access points so that a continuous coverage area is created, wireless users within this ESS can roam freely. All wireless adapters and access points within a specific ESS must be configured with the same SS ID and to the same radio channel.

Adapter Installation Problems If your computer cannot find the EZ Connect Wireless PC Card or the network driver does not install correctly, check the following:
Make sure the adapter is securely seated in the PCMCIA slot. When you insert the wireless adapter into the notebooks slot, a beep should be heard if the adapter is properly inserted. Check for any hardware problems, such as physical damage to the cards connector.
Try the card in another PCMCIA slot. If this also fails, test your computer with another SMC2632W V.2 Wireless PC Card that is known to operate correctly.
When operating under Windows NT, make sure a PCMCIA card and socket services driver is installed in your computer. Also check for resource conflicts using the Windows NT Diagnostics utility.
Make sure your computer is using the latest BIOS.
If there are other network adapters in the computer, they may be causing conflict. Remove all other adapters from the computer and test the wireless adapter separately. 18 NETWORK CONNECTION PROBLEMS
Check for a defective computer or PCMCIA connection by trying the adapter in another computer that is known to operate correctly.
If it still does not work, take out the wireless adapter. Delete CW10.sys from c:\windows\system. Then go to Control Panel and delete the adapter from your network configuration menu. Restart your PC and reinstall the card. Network Connection Problems If the Link LED on the PC Card does not light, or if you cannot access any network resources from the computer, check the following:
Make sure the correct software driver is installed for your operating system. If necessary, try reinstalling the driver.
Make sure the computer and other network devices are receiving power.
The access point you want to attach to may be defective. Try using another access point.
If you cannot access a Windows or NetWare service on the network, check that you have enabled and configured the service correctly. If you cannot connect to a particular server, be sure that you have access rights and a valid ID and password.
If you cannot access the Internet, be sure you have configured your system for TCP/IP. 19 If your wireless station cannot communicate with a computer in the Ethernet LAN when configured for Infrastructure mode, check the following:
Make sure the access point which the station is associated with is powered on.
If you still cant connect, change the access point and all the stations within the BSS to another radio channel.
Make sure the SSID is the same as that used by the acess point for a station with roaming disabled, or the same as that used by the access points in the extended service set (ESS). 20 NETWORK CONNECTION PROBLEMS SMC Networks 802.11b Wireless Product Maximum Distance Table Important Notice Maximum distances posted below are actual tested distance thresholds.

Access Point An internetworking device that seamlessly connects wired and wireless networks. Ad Hoc An ad hoc wireless LAN is a group of computers, each with LAN adapters, connected as an independent wireless LAN. Backbone The core infrastructure of a network. The portion of the network that transports information from one central location to another central location where it is unloaded onto a local system. Base Station In mobile telecommunications, a base station is the central radio transmitter/receiver that maintains communications with the mobile radiotelephone sets within its range. In cellular and personal communications applications, each cell or micro-cell has its own base station; each base station in turn is interconnected with other cells bases. BSS BSS stands for Basic Service Set. It is an Access Point and all the LAN PCs that are associated with it. CSMA/CA Carrier Sense Multiple Access with Collision Avoidance. ESS ESS (ESS-ID, SSID) stands for Extended Service Set. More than one BSS is configured to become an Extended Service Set. LAN mobile users can roam between different BSSs in an ESS
(ESS-ID, SSID). 24 TERMINOLOGY Ethernet A popular local area data communications network, which accepts transmission from computers and terminals. Ethernet operates on a 10 Mbps baseband transmission rate, using shielded coaxial cable or shielded twisted-pair telephone cable. Infrastructure An integrated wireless and wired LAN is called an Infrastructure configuration. Roaming A wireless LAN mobile user moves around an ESS and maintains a continuous connection to the Infrastructure network. RTS Threshold Transmitters contending for the medium may not be aware of each other. The RTS/CTS mechanism can solve this Hidden Node Problem. If the packet size is smaller than the preset RTS Threshold size, the RTS/CTS mechanism will NOT be enabled. WEP Wired Equivalent Privacy is based on the use of 64-bit or 128-bit keys and the popular RC4 encryption algorithm. Wireless devices without a valid WEP key will be excluded from network traffic. 25 TERMINOLOGY 26 FOR TECHNICAL SUPPORT, CALL:
