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 Page Click 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 16 Client 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 17 Client Manager Configuration Survey Page Click 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. 18 Client Manager Configuration Once 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 19 Profiles Page Click 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.
