Network Type Set the station operation mode to Ad Hoc for network configurations that do not have an access point, or to Infrastructure for configurations with an access point. 13 USING THE SMCWPCI-G2 UTILITY PROGRAM Security Tab Go to the security tab to set the security features for your adapter. Click on this security button to turn on/turn off the security function. Turn on the security function, and set detail parameters for your adapter. To prevent unauthorized access, this adapter supports WEP

(Wired Equivalent Privacy), and WPA/WPA2-PSK (Wi-Fi Protected Access). 14 USING THE SMCWPCI-G2 UTILITY PROGRAM WEP WEP implemented in the SMCWPCI-G2 is based on the RC4 encryption algorithm. The security keys provided to ensure data confidentiality are four 10-bit keys for the 64-bit WEP setting and one 26-bit key for the 128-bit WEP setting. WEP security protects your wireless LAN against eavesdropping and unauthorized access by intruders. Security Type WEP (Wired Equivalent Privacy) and WPA(2)-PSK (Wi-Fi Protected Access-Pre-Shared Key) are implemented in the SMCWUSBS-N2 adapter to prevent unauthorized access. Key Type Select 64-bit encryption, 64-bit encryption (ASCII), 128-bit encryption,or 128-bit encryption (ASCII). Default Key Choose one key, 1~4, for encryption. Use Passphrase Check this box to auto-generate keys for encryption. First, check this box, then enter a string of characters into the space. Encryption keys will be generated automatically. When Key Type is set to 128-bit, only one key will be generated. If Key Type is set to 64-bit, four keys will be generated. Note that you must use the same passphrase and default key on all the other clients in your network. How to set up WEP:

If you are transmitting sensitive data across wireless channels, you should enable Wired Equivalent Privacy (WEP) encryption. WEP provides a basic level of security, preventing unauthorized access to the network and encrypting data transmitted between wireless clients and the access point. WEP uses static shared keys (fixed-length hexadecimal or alphanumeric strings) that are manually distributed to all clients that want to use the network. 15 USING THE SMCWPCI-G2 UTILITY PROGRAM WEP is the security protocol initially specified in the IEEE 802.11 standard for wireless communications. For more robust wireless security, the SMCWPCI-G2 provides Wi-Fi Protected Access

(WPA) for improved data encryption and user authentication. Only one key is needed for WEP to function. However, the IEEE 802.11 standard specifies that there must be four keys for each device. For security purposes, the key should be changed on a regular basis. Multiple keys are supported to allow the user to change keys with minimal disruption of the network. To set up the WEP function, take the following steps:

Select 64-bit encryption, 64-bit encryption (ASCII), 128-bit encryption,or 128-bit encryption (ASCII) in the Key Type field. To automatically generate keys, check the Use Passphrase box, and type in a string of characters in this field. In the Default Key field, select one key as the default key that you want to use for encryption. Or Select 64-bit encryption, 64-bit encryption (ASCII), 128-bit encryption,or 128-bit encryption (ASCII) in the Key Type field. In the Default Key field, select one key as the default key that you want to use for encryption. Manually type in a string of characters in the corresponding key number field that you selected in step 2. Click Apply Change to allow the settings to take effect. 16 USING THE SMCWPCI-G2 UTILITY PROGRAM When setting up WEP without using the Use Passphrase function, if the Key Type is set to Hex, only Hexadecimal characters (range: 0~9 and A~F) can be used. When encryption is set to 64-bit, a maximum of 10 Hex characters can be entered in the Key field. When encryption is set to 128-bit, a maximum of 26 Hex characters can be used. If the Key Type is set to ASCII, and encryption is set to 64-bit, then 5 ASCII characters can be used in the Key field. For 128-bit encryption, 13 ASCII characters can be used. WPA-PSK/WPA2-PSK How to set up WPA/WPA2-PSK:

Wi-Fi Protected Access is a standards-based, interoperable security enhancement that strongly increases the level of data 17 USING THE SMCWPCI-G2 UTILITY PROGRAM protection and access control for existing and future wireless LAN systems. It will be forward-compatible with the upcoming IEEE 802.11i standard. WPA employs a combination of several technologies to provide an enhanced security solution for 802.11 wireless networks, including TKIP (Temporal Key Integrity Protocol) for data protection and 802.1x for authenticated key management. WPA provides a simple operating mode that uses just a pre-shared password for network access. The Pre-Shared Key mode uses a common password for user authentication that is manually entered on the access point and all wireless clients on the network. To use the WPA function, take the following steps:

1. Select Security Type, WPA-PSK/WPA2-PSK from the drop-down menu. 2. Type in the WPA Passphrase (Pre-Shared Key: PSK). 3. Choose Encryption method for data protection of the WPA-PSK. 4. Select ASCII or Hex in the Key Type field 5. Click Apply Change to allow the settings to take effect. Note: The WPA Passphrase character limit needs to be between 8-63 characters. Manual Pre-Shared Key supports up to 64-Hex characters. If there is no authentication server on your SOHO network, you can issue the Pre-Shared Key to the adapter that is connected to the access point. Be sure to use the same key for the wireless access point and the connected adapter. 18 USING THE SMCWPCI-G2 UTILITY PROGRAM Advanced RTS Threshold This sets the packet size threshold at which a Request to Send (RTS) signal must be sent to the receiving station prior to the sending station starting communications. Devices contending for the wireless medium may not be aware of each other. The RTS mechanism can solve this problem. The larger the threshold, the faster the speed. 19 USING THE SMCWPCI-G2 UTILITY PROGRAM Fragment Threshold Sets the minimum packet size that can be transmitted from the adapter without being fragmented. Fragmentation can increase the reliability of transmissions because it increases the probability of a successful transmission due to smaller frame size. The larger the threshold, the faster the speed. Preamble Type The preamble is used to acquire the incoming signal and synchronize the receiver. If all the clients in your service area support the short preamble or can automatically set the preamble type, then setting the preamble on the access point to short can boost your throughput. (Options: Short & Long, Long only, Short only; Default: Short & Long) Quality of Service (QoS) The QoS function allows you to differentiate traffic types and provide high-priority forwarding service for applications such as VoIP or gaming. Transmit Power Move the slider bar up and down to select an appropriate transmission power. Lower power reduces interference, higher power gives more range. 20 USING THE SMCWPCI-G2 UTILITY PROGRAM Link Information The Link information screen displays information on the current wireless network to which you are connected. Network Name This is the Service Set ID (SSID) for the wireless network to which you want to connect. Base Station Name ID The MAC address of the access point to which the card is connected in an Infrastructure network. In an Ad Hoc network, this ID is a random number generated by the first station that communicates with other stations in the network. The BSS ID of the other stations will then be set to the same value. 21 USING THE SMCWPCI-G2 UTILITY PROGRAM Channel This is the radio channel through which the access point communicates to stations within the same network. A Basic Service Set (BSS) consists of a group of wireless PCs and an access point that is directly connected to the wired LAN. To establish an Ad Hoc network, make sure the Channel is set 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, the adapter will automatically use the same channel as that used by the access point. The available channel settings are limited by local regulations that determine the number of available channels. Current Connection Speed Shows the speed of the current wireless connection. Throughput Shows the total number of data packets transmitted and received. Signal Strength Shows the relative strength of the wireless connection.

The SMCWPCI-G2 can be configured as:

Ad hoc - for small groups that only communicate with each other Infrastructure - for mixed wired/wireless LANs Network Topologies Ad Hoc Wireless LAN An Ad Hoc wireless LAN consists of a group of computers, each equipped with a wireless adapter, connected via radio signals as an independent wireless LAN. Computers in a specific Ad Hoc wireless LAN must be configured to the same radio channel. An Ad Hoc wireless LAN can be used in a SOHO or temporary environment. 26 Ad Hoc Wireless LAN Notebook with Wireless USB Adapter Notebook with Wireless PC Card PC with Wireless PCI Adapter NETWORK TOPOLOGIES Infrastructure Wireless LAN The SMCWPCI-G2 also provides 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 USB/PC Card Adapter Access Point PC with Wireless USB/PCI Adapter 27 SETTING THE COMMUNICATION DOMAIN 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 Service Set Identifier (SSID) for the wireless card to the SSID of the access point to which you want to connect. Check with your network administrator for the SSID. 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 SSID and to the same radio channel.

Adapter Installation Problems If your computer cannot find the Wireless PCI Adapter, or the network driver does not install correctly, check the following:

Make sure the adapter is securely seated in the PCI slot. Check for any hardware problems, such as physical damage to the cards connector.

Try the card in another PCI slot. If this also fails, test your computer with another PCI adapter that is known to operate correctly.

Make sure your computer is using the latest BIOS.

If there are other network adapters in the computer, they may be causing conflicts. Remove other adapters from the computer and test the wireless adapter separately. Check for a defective computer or PC connection by trying the adapter in another computer that is known to operate correctly. 30 NETWORK CONNECTION PROBLEMS Network Connection Problems If the Link LED on the SMCWPCI-G2 does not light, or if you cannot access 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 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. 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 that the station is associated with is powered on.

If you still cannot 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 BSS configured on the access point, or the same as that used by the access points in the extended service set (ESS). 31 NETWORK CONNECTION PROBLEMS SMCWPCI-G2 Maximum Distance Table Important Notice Maximum distances posted below are actual tested distance thresholds.
