Click on the “Monitor” tab to view the network status of the wireless adapter. USING THE SMC2632W WLAN UTILITY Click “Change” to configure the “Operating Mode,” “Channel,” “SSID” and “Tx Rate.” After making a configuration change, the Submit button will become enabled. Click “Submit” to save the changes. Operating Mode – Set the station operation mode to “802.11 Ad Hoc” for network configurations that do not have an access point, or to “Infrastructure” for configurations with an access point (“Infrastructure” is the default setting.) Channel – If you are setting up an ad hoc wireless LAN (See “Network Topologies” on page 14.), set the channel number to the same radio channel as that used by the other wireless clients in your group. However, if you are connecting to a network via an access point, then the channel is automatically set to the channel of the access point to which the adapter connects. Note: The Channel can only be set when the Operating Mode is “802.11 Ad-Hoc.” SSID – Input an SSID string for the wireless network to which you want to connect (“WLAN” is the default setting.) If you will be roaming among multiple access points with different BSSIDs, set the SSID to “ANY” to allow connection to any access point. Tx Rate – Indicates the data transmission rate. Select an appropriate transmission speed. Lower speeds will give better range. (Default: Auto.) Status - Shows the MAC address of the associated access point (BSS ID). Signal Strength – Shows the relative strength of the wireless connection to the access point. Link Quality – Shows the relative link quality (e.g., lack of frame errors) of the wireless connection to the access point. USING THE WIRELESS LAN UTILITY Statistics The Statistics screen displays “Data Frames” and “Management Frames.” Site Survey The Site Survey screen displays all access points in the wireless LAN. You can choose one of them to connect to by double-clicking on an entry. Encryption Encryption – Wired Equivalent Privacy (WEP) is implemented in the adapter to prevent unauthorized access. For more secure data transmissions, set encryption to “128-bit” or “64-bit”. The 128-bit setting gives a higher level of security. The setting must be the same for all clients in your wireless network (Default: Disabled). The WEP (Wired Equivalent Privacy) implemented in SMC’s EZ Connect Wireless PC Card is based on the RC4 encryption algorithm. The security keys are four 10 digit keys for the 64-bit WEP setting and one 26-digit key for the 128-bit WEP setting. WEP USING THE WIRELESS LAN UTILITY security protects your wireless LAN against eavesdropping and unauthorized access by hackers or intruders. WEP Key – Security keys for WEP encryption are generated from your encryption string, so you must use the same key on all the other stations in your network. Authentication Type – Set this to the same as the other devices in your network. SMC devices use “Shared Key.” Devices from some other vendors use “Open System.” (Default: Auto) To use the WEP function, take the following steps: 1. Select “128-bit” or “64-bit” in the “Encryption” field. 2. Choose Key #1 ~ Key #4 from “WEP Key to use.” 3.

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 Ad Hoc Wireless LAN consists of a group of computers, each equipped Notebook with Wireless USB Adapter with one wireless adapter, connected via radio signals as an independent wireless LAN. Computers in a specific Notebook with Wireless PC Card ad hoc wireless LAN must therefore be configured to PC with Wireless the same radio channel. An PCI Adapter ad hoc wireless LAN can be used in a SOHO or temporary environment. 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. File Server Desktop PC Switch Wireless Cell Coverage Area Notebook with Wireless PC Card Adapter PC with Wireless PCI Adapter Access PointAccess Point PC with Wireless PC I Adapter Notebooks with Wireless PC Card Adapters 16 Seamless Roaming SETTING THE COMMUNICATION DOMAIN Before 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.) 17 TROUBLESHOOTING TROUBLESHOOTING Check the following troubleshooting items before contacting SMC Technical Support. 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: 18 • 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 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: 20 • 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).

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: From U.S.A. and Canada (24 hours a day, 7 days a week) (800) SMC-4-YOU; (949) 679-8000; Fax: (949) 679-1481 From Europe (8:00 AM - 5:30 PM UK Time) 44 (0) 118 974 8700; Fax: 44 (0) 118 974 8701 INTERNET E-mail addresses: techsupport@smc.com european.techsupport@smc-europe.com Driver updates: http://www.smc.com/index.cfm?action=tech_support_drivers_downloads World Wide Web: http://www.smc.com/ http://www.smc-europe.com/ FOR LITERATURE OR ADVERTISING RESPONSE, CALL: U.S.A. and Canada: Spain: UK: France: Italy: Benelux: Central Europe: Switzerland: Nordic: Northern Europe: Eastern Europe: Sub Saharian Africa: North Africa: Russia: PRC: Taiwan: Asia Pacific: Korea: Japan: Australia: India: (800) SMC-4-YOU; 34-93-477-4935; 44 (0) 118 974 8700; 33 (0) 41 38 32 32; 39 02 739 12 33; 31 33 455 72 88; 49 (0) 89 92861-0; 41 (0) 1 9409971; 46 (0) 868 70700; 44 (0) 118 974 8700; 34 -93-477-4920; 27-11 314 1133; 34 93 477 4920; 7 (095) 290 29 96; 86-10-6235-4958; 886-2-2659-9669; (65) 238 6556; 82-2-553-0860; 81-45-224-2332; 61-2-9416-0437; 91-22-8204437; Fax (949) 679-1481 Fax 34-93-477-3774 Fax 44 (0) 118 974 8701 Fax 33 (0) 41 38 01 58 Fax 39 02 739 14 17 Fax 31 33 455 73 30 Fax 49 (0) 89 92861-230 Fax 41 (0) 1 9409972 Fax 46 (0) 887 62 62 Fax 44 (0) 118 974 8701 Fax 34 93 477 3774 Fax 27-11 314 9133 Fax 34 93 477 3774 Fax 7 (095) 290 29 96 Fax 86-10-6235-4962 Fax 886-2-2659-9666 Fax (65) 238 6466 Fax 82-2-553-7202 Fax 81-45-224-2331 Fax 61-2-9416-0474 Fax 91-22-8204443 If you are looking for further contact information, please visit www.smc.com or www.smc-europe.com. 38 Tesla Irvine, CA 92618 Phone: (949) 679-8000 Model Number: SMC2632W V.2 Revision Number: F1.0 E042002-R01
