12SMC2862W-G UTILITYTo communicate with other SMC 802.11g or 802.11b devices, you need to configure the SMC2862W-G adapter first. Double-click the SMC2862W-G Utility icon on the desktop to launch the configuration utility, or you can access it from the Start menu.Note that the screen shots were taken from Windows XP and will not look exactly the same in all operating systems.Icon on the desktop:Icon on the toolbar:

Configuration15Transmit Rate – Indicates the data transmission rate. Select an appropriate transmission speed. Lower speeds will give better range.Power Save Mode – To use this funtion, select the Enabled or Disabled in the Power Save Mode drop-down menu, then click the Apply Change button.SecurityThe Security ON/Security OFF button indicates whether the security function has been enabled or disabled. Click the Security ON/Security OFF button to enable the security function. (Default: Security OFF)

SMC2862W-G Utility16Authentication Type – WPA-PSK (Wi-Fi Protected Access-Pre Share Key) and WEP (Wired Equivalent Privacy) are implemented in the SMC2862W-G adapter to prevent unauthorized access.WPA-PSKHow to set up WPA: Wi-Fi Protected Access is a standards-based, interoperable security enhancement that strongly increases the level of data protection and access control for existing and future wireless LAN systems. It will be forward-compatible with the upcomingIEEE 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 Authentication Type, WPA-PSK from the drop-down menu.2. Type in the Pre-Shared Key (PSK).3. Click Apply Change to allow the settings to take effect.Note: The PSK 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.

Configuration17For enterprise deployment, WPA requires a RADIUS authentication server to be configured on the wired network. The 802.1x client and RADIUS server should use an appropriate EAP type - such as EAP-TLS (Transport Layer Security), EAP-TTLS (Tunneled TLS), or PEAP (Protected EAP) - for strongest authentication. Working together, these protocols provide “mutual authentication” between a client, the access point, and a RADIUS server that prevents unauthorized users from joining your network, and also prevents users from accidentally joining a rogue network. Only when a RADIUS server has authenticated a user’s credentials will encryption keys be sent to the access point and client.Note: To implement WPA on wireless clients requires a WPA-enabled network card driver and 802.1x client software that supports the EAP authentication type that you want to use. Windows XP provides native WPA support, other systems require additional software. Note that Microsoft now has an 802.1x authentication client for Windows 2000 that you can download from their web site.

SMC2862W-G Utility18WEPAuthentication Mode – Choose Open or Shared.Default Key – Choose the key for encryption.Key Type – Select 64-bit encryption, 64-bit encryption (ASCII), 128-bit encryption,or 128-bit encryption (ASCII).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.

Configuration19How 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. WEP is the security protocol initially specified in the IEEE 802.11 standard for wireless communications. For more robust wireless security, the SMC2862W-G provides Wi-Fi Protected Access (WPA) for improved data encryption and user authentication. Note: 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: 1. Select 64-bit encryption, 64-bit encryption (ASCII), 128-bit encryption,or 128-bit encryption (ASCII) in the Key Type field.2. To automatically generate keys, check the Use Passphrase box, and type in a string of characters in this field.3. In the Default Key field, select one key as the default key that you want to use for encryption.4. Click Apply Change to allow the settings to take effect.

SMC2862W-G Utility20Or 1. Select 64-bit encryption, 64-bit encryption (ASCII), 128-bit encryption,or 128-bit encryption (ASCII) in the Key Type field.2. In the Default Key field, select one key as the default key that you want to use for encryption.3. Manually type in a string of characters in the corresponding key number field that you selected in step 2.4. Click Apply Change to allow the settings to take effect.Note: 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.

Configuration21AdvancedRTS 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/CTS mechanism can solve this problem. The larger the threshold, the faster the speed.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.

SMC2862W-G Utility22Preamble 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, Short; Default: Short & Long)Transmit Power – Move the slider bar up and down to select an appropriate transmission power. Lower power reduces interference, higher power gives more range.

30NETWORK CONFIGURATIONAND PLANNINGSMC’s EZ Connect g Wireless Solution supports a stand-alone wireless network configuration, as well as an integrated configuration with 10/100 Mbps Ethernet LANs.The SMC2862W-G can be configured as:•Ad hoc - for small groups that only communicate with each other, without access points•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. Notebook withWireless USB AdapterNotebook withWireless PC CardPC with WirelessPCI AdapterAd Hoc Wireless LAN

Network Topologies31Infrastructure Wireless LANsThe SMC 802.11g access point (SMC2870W) 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.FileSer v erSw i t c hDesktop PCAccess PointWired LAN Extensionto Wireless AdaptersPC w i t h W i r e l essUSB/PCI AdapterNotebook with WirelessUSB/PC Car d Ad apt er

Network Configuration and Planning32Setting 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 to which you want to connect. Check with your administrator for the SSID of the access point to whick you are connecting.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.You can configure the wireless client to connect to a specific wireless network or to the first available wireless network. •If you configure the client to connect to a specific wireless network, the client establishes a radio connection to the AP in the specified wireless network that provides the best communications quality. APs in a different wireless network are ignored. •If you configure the client to connect to the first available wireless network (the SSID = ANY), the client establishes a radio connection to the AP that provides the best communications quality. Be aware that if there are multiple wireless networks, the client could connect to an AP that is not in the network you want to join.
