NETWORK CONFIGURATION AND PLANNING14NETWORK CONFIGURATIONAND PLANNINGSMC’s EZ Connect Wireless Solution supports a stand-alone wireless network configuration, as well as an integrated configuration with 10/100 Mbps Ethernet LANs.The SMC2632W V.2 can be configured as:•Ad hoc - for small groups that only communicate with each other•Infrastructure - for wireless LANsNetwork TopologiesAd Hoc Wireless LANAn 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.Ad Hoc Wireless LANNotebook withWireless USB AdapterNotebook withWireless PC CardPC with WirelessPCI Adapter
NETWORK TOPOLOGIES15Infrastructure Wireless LANThe 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.FileServerSwitchDesktop PCAccess PointWired LAN Extensionto Wireless AdaptersPC with WirelessPC I AdapterNotebook with WirelessPC Card Adapter
NETWORK CONFIGURATION AND PLANNING16Setting the Communication DomainStationary 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.FileServerSwitchDesktop PCAccess PointNotebooks with WirelessPC Card AdaptersSeamless Roaming<BSS2><ESS><BSS1>PC with WirelessPC I AdapterPC with WirelessPCI AdapterNotebook with WirelessPC Card AdapterAccess PointWireless CellCoverage Area
SETTING THE COMMUNICATION DOMAIN17Before setting up an ESS for roaming, you need to choose a clear radio channel and ideal location for the access points to maximize performance. (Refer to “Troubleshooting” on page 18 for detailed information on installation and usage.)
TROUBLESHOOTING18TROUBLESHOOTINGCheck the following troubleshooting items before contacting SMC Technical Support.Adapter Installation ProblemsIf 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 notebook’s slot, a beep should be heard if the adapter is properly inserted. Check for any hardware problems, such as physical damage to the card’s 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.
NETWORK CONNECTION PROBLEMS19•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 ProblemsIf 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.
20If 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 can’t 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).

24TERMINOLOGYThe following is a list of terminology that is used in this document.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).
TERMINOLOGY25Ethernet – 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.
