15Client Manager ConﬁgurationUse Client Manager to conﬁgure your wireless network. To assist in conﬁguring your wireless network, Client Manager consists of the Status page, the Survey page, and the Proﬁles page. You can access each page by clicking the corre-sponding button on Client Manager. In addition to these pages, several dialog boxes are available to meet specialized conﬁguration needs. You can access the Edit Proﬁle dialog box, New Proﬁle dialog box, IP Conﬁguration dialog box, or WEP Conﬁguration dialog box using the Client Manager pages. Status PageClick the Status button to open this page. By default, this page is dis-played when you start Client Manager. This page displays the status of the connection be-tween the wireless adapter and another wireless device. This page only displays connection information no changes to the connection can be made from this screen.This page includes the following components:Client Manager Conﬁguration

16Client Manager Conﬁguration• Rate – The speed that the two wireless clients are communicating at. If the Client Manager is not connected to a remote wireless device (access point or another client) then no rate will be displayed.• Channel – The channel that the two wireless clients are communicating at. If the Client Manager is not connected to a remote wireless device (access point of another client) then no channel will be displayed. The available chan-nels for use are 1-11.• Security– The type of encryption that the two wireless clients are communicat-ing with. If the Client Manager is not connected to a remote wireless device (access point of another client) then ‘No Encryption’ will be displayed.• IP Address – The IP address of the machine the Client Manager is installed on. If the Client Manager is not connected to a remote wireless device (access point of another client) or is not connected to a network with DHCP, then no IP address will be displayed.• MAC Address – The MAC address of the wireless client device inside the com-puter Client Manager is installed on. If no wireless device is present in the computer, then no MAC Address will be displayed.• Signal Strength – Displays the strength of the signal. Signal Strength is based on the peak signal level the wireless adapter receives from the wireless device to which it is connected. Next to the signal level is the wireless hardware type

17Client Manager ConﬁgurationSurvey PageClick the Survey button to open this page. Use this page to survey the area, dis-play available access points, and connect to available access points.This page includes the following components:• Wireless SSID – Displays the SSID as-sociated with each available access point. The SSID is the unique net-work name that functions as an iden-tiﬁer for your wireless devices. All wireless devices on a network must use identical SSIDs to successfully associate with other devices on the network. buffalo_test is an example of a valid SSID.• Mode – Displays the mode/rate set that the remote wireless device is offering.• Key – Displays whether the wireless network is using any sort of encryption.

18Client Manager ConﬁgurationOnce the ‘Connect’ button is pressed, you will be prompted to enter any encryp-tion related information.The ‘Acquire IP automatically’ checkbox tells the client device to obtain an IP automati-cally from a DHCP server. This is the rec-ommended setting.The ‘Encryption’ drop down list allows you to select the type of encryption for the net-work. By default the proper encryption type should already be selected. In the event that no encryption is used, leave the ‘No Encryption’ option selected.by the wireless network must be inputted. Please consult your wireless access point or router’s documentation for proper input of the encryption keys. Some wireless networks may require you to enter multiple keys, in this event, four separate ﬁelds are available for encryption keys.The ‘Save settings as a proﬁle’ option will store this wireless network in your pro-ﬁles. This means you will automatically connect to this network when inside

19Proﬁles PageClick the Proﬁles button to open this page. Use this page to access your proﬁles. Proﬁles allow you to save the information associated with a speciﬁc wireless network so you can quickly and easily connect to that network when you are in that loca-tion. The Proﬁles page allows you to add, delete, and edit your proﬁles, as well as import and export data.• Connect – Click the Connect button to connect to the selected proﬁle and return to the ‘Status’ page.• Edit – Click the Edit button to edit the selected proﬁle’s settings. The Edit but-ton also allows you to delete a proﬁle no longer used or required.• Add – Click the Add button to add a proﬁle manually. You will need important information such as SSID, encryption settings, and network type.Client Manager Conﬁguration

20New Proﬁle Dialog BoxUse this dialog box to create a new proﬁle.Client Manager Conﬁguration• Proﬁle Name – Enter the name you want to associ-ate with the new proﬁle.• Network Type – Select the network mode you want to associate with the new proﬁle. Select Infra-structure if your network consists of both wired and wireless devices that communicate through a central device, such as an access point. Select Ad-hoc if your network consists of only wire-less devices that communicate with each other directly.• Network Name SSID – Enter the SSID of your net- must use identical SSIDs to successfully associate with other devices on the network. myssid is an example of a valid SSID. • Channel – Displays the channel associated with the new proﬁle. The channel indicates what range of frequencies the radio waves emitted by the wireless device are occupying. Devices that meet 802.11b and 802.11g standards can use channels 1-11 within the 2.4 GHz spectrum.• Encryption Type – Displays the types of encryptions available. Once selected, you will be required to enter the Encryption Key Number and the Encryption Key as well. For the Encryption Key Number, it is recommended to use 1 unless speciﬁed to by an administrator.

23Wireless Zero ConﬁgurationWireless Zero Conﬁguration Service (Windows XP)Windows XP offers the Wireless Zero Conﬁguration Service to support 802.11b and 802.11g wireless networking. This service automatically polls the area for available wireless access points. If an available wireless access point is found, Windows attempts to connect to the access point. If no available wireless ac-cess points are found, you must manually add the access points.■ Note: The Wireless Zero Conﬁguration Service and Client Manager do not function properly together. If you want to use Client Manager, you must disable the Wireless Zero Conﬁguration Service.

26Troubleshooting / FAQTroubleshooting / FAQUse this section to locate answers to frequently asked questions.What should I do if I already have a version of Client Manager on my PC? Update your Client Manager to the version on the CD. If you do not update your Client Manager, there could be a loss of functionally, as some versions of Client Manager will not work properly with the G54 Wireless 54Mbps Desktop PCI Adapter. Before updating Client Manager, you must uninstall all previous versions of Client Manager. To update your Client Manager, load the Air Navigator CD and select Install Client Manager.Why won't all my network clients work? Some operating systems support only a limited number of network clients.Windows 98/Me: These operating systems support only four network clients. If you install more than four network clients, only the ﬁrst four clients you install will work.Will Client Manager support all operating systems? Client Manager and the G54 Wireless 54Mbps Desktop PCI Adapter currently support only Windows 98/ME/2000/XP. They do not currently support Windows NT, Mac OS, or Linux. For more information, refer to the Mac OS and Linux page
