15Software setupInstalling the supplied softwareThis section explains how to install the Wireless LAN PC Card driver andWireless Panel.Before you startMake sure that you can use your CD-ROM drive.ImportantComputer Firewall FunctionsWhen using Windows XP’s “Internet Connection Firewall”Enabling the Windows XP “Internet Connection Firewall” may prevent you frombeing able to access your computer through wireless communication. (This functionis inactive under Windows XP default settings.) Because of this function, you maynot be able to connect to your network when you change your Access Point settings.If this happens, deactivate the “Internet Connection Firewall” function, connect tothe network, and then reactivate the function. For details, refer to Windows XPHelp.NoteNetwork security is an important issue. You are urged to consider carefully how best to protect yourcomputer.When using a personal firewall function provided by virus scanningor network security softwareVirus scanning and network security software sometimes includes a function calleda “personal firewall” that is designed to prevent illegal access by outside entities.Depending on the software, the security level of this function may be initially set toa high level. If this high security level setting is left in effect, it may be impossiblefor an outside entity to access your computer. This can cause problems such as notbeing able to connect to the network when changing the Access Point’s settings. Inthis event, lower the security level in order to permit the network connection. Fordetails, refer to the manuals provided with your software.Notes•Pay special attention to security issues.•For questions regarding firewall functions, please contact your firewall software manufacturer.

19Wireless LAN connection3Configure the “Network Name (SSID)” and “WEP” items.1Network Name (SSID)This is a unique ID used to identify wireless networks. The settingcan be made individually for Access Point Network connectionmode and Peer to Peer Network connection mode. When connectingto an existing network, consult your network administratorregarding the proper settings. For Peer to Peer Network connectionmode and when changing an existing Network Name, you can useup to 32 alphanumeric characters (including symbols).z Hints•Opening the “Network Name” drop-down list will show the Network Namesof any Access Points within range. You can then select a Network Name fromthe list.•When using the Sony 5GHz Wireless LAN Access Point PCWA-A500, thedefault Network Name (SSID) of the Access Point is shown on the ID label ofthe Access Point. For details on the position of the label and other information,refer to the manuals provided with the Access Point.An explanation ofthe respective itemis shown here.21

202WEPIf Data Encryption (WEP) is enabled for the Access Point to whichyou connect, check this item. When this item is checked, you alsoneed to enter the encryption key (WEP key) in the “Key” field.The data encryption function serves to prevent unauthorized accessto the network. For security reasons, it is strongly recommendedthat you enable this feature. The setting can be configuredindividually for Access Point Network connection mode and Peer toPeer Network connection mode. When connecting to an existingnetwork, consult your network administrator regarding the propersettings.

You cannot modify settings whenlogged on with any other account.•On a computer running Windows XP, communication setup and network switching arenot performed with the Wireless Panel but with built-in functions of Windows XP.However, the Wireless Panel can be used to check the communication status.Opening the Wireless PanelTo open the Wireless Panel, proceed as follows.Double-click the signal level indicator in the taskbar.The Wireless Panel appears.z Hints•For information on the signal level indicator, see “Checking the wireless signalstrength” on page 39.•When you move the mouse pointer over an item in the Wireless Panel screen, a shortdescription of that item appears.

422StatusShows the communication status of the wireless network.“Network Name”Unique ID for the wireless network to which the computer isconnected. Also called SSID.“Frequency”Indicates the communication channel and frequency currently beingused.“Signal Level”Indicates the signal level as a bar graph.Install the computer and Access Point so that the signal leveldisplayed here is as high as possible.“IP Address”Indicates the computer’s IP address.In Access Point Network connection mode, if an IP address startingwith “169.254. ...” or if “0.0.0.0” is shown here, the Access Pointand computer are not linked, or the Access Point is not connected tothe Internet. For details, refer to the “Wireless LAN Quick Guide”or the “Troubleshooting Guide”.“Frames Sent”Shows the total number of network data frames that have been sent.“Frames Received”Shows the total number of network data frames that have beenreceived.“Link Rate (TX)”Shows the transmission rate.“Link Rate (RX)”Shows the reception rate.“Throughput (TX)”Shows the current transmission rate and maximum transmission rateof the session in the format “Current Mbps/Max. Mbps”. Themaximum value update frequency corresponds to the time width ofthe status graph.“Throughput (RX)”Shows the current reception rate and maximum reception rate of thesession in the format “Current Mbps/Max. Mbps”. The maximumvalue update frequency corresponds to the time width of the statusgraph.

43Wireless LAN connection3Wireless ON/OFFWireless signal transmission can be switched on/off independently forthe 802.11b (2.4 GHz) and 802.11a (5 GHz) bands. Select the On/Offstatus according to the environment you are in. Take special care if youare using your computer in locations where radio emissions areprohibited, such as outdoors (802.11a band) or within an aircraft(802.11a and 802.11b bands). Be sure to set wireless signaltransmission to Off with these buttons in such cases.4“Streaming Mode” buttonThis button is shown only when using Windows XP. It allows you totemporarily suspend the Windows XP wireless configuration functions(Wireless Zero Configuration service) in order to optimize throughputfor real-time playback of streaming data.5Graph scaleThis is a scale for transmission and reception link rate and throughput.Normally, the transmission and reception throughput will be about halfthe link rate.6Status indicator graphShows the signal level, RX link rate, and TX throughput. Theseparameters are useful for finding the optimum location of computerand Access Point, and for measuring throughput.7“Renew IP” buttonClicking this button causes the computer to release the currentlyassigned IP address and obtain a new IP address.Notes•When a fixed IP address has been assigned to the computer, this function cannotbe used.•Under Windows Me, this function cannot be used.

448“AP Setting” buttonClicking on this button starts your Web browser and displays theAccess Point home page (setup page). This page lets you configure theAccess Point and display status information. In Peer to Peer Networkconnection mode, this button cannot be used.NoteThe “AP Setting” button can only be used when you are using the Sony 5GHzWireless LAN Access Point PCWA-A500* or another 5GHz Wireless LAN AccessPoint which supports this feature. (* As of February, 2003)9“Show Graph/Hide Graph” buttonLets you turn the status graph on an off. The default setting is off.“Network List”The “Network List” tab shows a list of 802.11a/b wireless networksoperating within communication range of the computer. You can select anetwork from this list to connect to, and you can register networks for thecomputer.12 3 4

46“Network Name (SSID)”Shows the unique network ID.z HintThe Sony 2.4GHz Access Point PCWA-A100/A200 can be configured not to showthe Network Name (SSID). (This is referred to as a “closed system”.) For a closedsystem Access Point, the “Network Name (SSID)” field in the network list will beblank.To connect to a closed system, obtain information about the Network Name(SSID) and encryption key (WEP key) from the network administrator and use thisinformation to register the network. When connected, the Network Name (SSID) isshown in the network list.“Signal Level”Shows the signal level (field strength) of the received radio signal.Higher numbers mean a better signal.“Channel”Shows the channel used by the respective network. If multiplenetworks use the same channel, communication may be impaired.2Wireless ON/OFFWireless signal transmission can be switched on/off independently forthe 802.11b (2.4 GHz) and 802.11a (5 GHz) bands. Select the On/Offstatus according to the environment you are in.
