It includes the following topics: • Overview of Wireless Networking • Airgo Client Utility • Navigating the User Interface Overview of Wireless Networking The Airgo Wireless LAN Client Adapter connects your PC to a wireless local area network (wireless LAN) by way of radio signals.
2 Introduction to the Airgo Client Utility Figure 4: Ad-Hoc Network A0018 Service Set Identifiers The Service Set Identifier (SSID) is a name that uniquely identifies a wireless local area network. Each device in the wireless network must have the same SSID configured in order to participate in the network. The SSID can be up to 32 alphanumeric characters in length and is also known as the wireless network name. The 802.
Airgo Client Utility The window shows the list of available networks. 3 Select your network, and click Advanced to open the Wireless Network Connection Properties window, Wireless Networks tab. 4 Clear the checkbox entitled Use Windows to configure my wireless network settings. 5 Click OK. You can now use the Airgo Client Utility to manage your wireless connections.
2 Introduction to the Airgo Client Utility Accessing the Airgo Client Utility If you followed the instructions in Chapter 1, the Airgo Client Utility is installed on your PC. To start the Airgo Client Utility: • Choose Start > Programs > Airgo Networks > Airgo Client Utility. The Airgo application icon will appear in the system tray. Using the Tray Icon When you start the Airgo Client Utility, a small signal icon becomes visible in the system tray on the Windows toolbar (Figure 5).

3 Configuration This chapter explains how to scan for and connect to wireless networks and how to set up a profile to store network configuration information.
3 Configuration Configuration Overview Figure 10 shows the Airgo Client Utility in Expanded View. Figure 10: Airgo Client Utility, Expanded View The Airgo Client Utility uses profiles to store information describing how your Airgo Wireless LAN Client Adapter connects to the wireless network. Each profile contains information about the type of network connection, security settings, and power settings.
Working with Profiles with the first access point it finds for which it can establish radio communications. Association normally happens automatically; however, it is recommended that you start the Airgo Client Utility once you are connected. This enables you to verify the configuration and confirm that the access point to which you are connected is a trusted component of your network. Whenever you open the Airgo Client Utility, the system performs an automatic scan.
3 Configuration You can edit any profile in the list, including the active one. If you edit and save the active profile, the system temporarily drops the network connection while implementing the changes. When the configuration change is complete, the network connection is restored. To edit a profile: 1 Highlight the profile name and click Edit. If the profile is active, the system requests confirmation that you want to continue. Click OK to open the profile window.
Profile Window Profile Window Figure 13 shows the Profile window, which opens when you double-click on an entry in the network list or highlight a listed profile and click Edit. This section provides an overview of the information in the Profile window. Profile Name The top of the window contains an area for the name of the profile. When you create a profile, select a name that clearly identifies the network.1 The default profile name is the SSID.
3 Configuration Figure 13: Advanced Profile Settings Network Settings The Network section shows the type of network (infrastructure or ad-hoc) and contains an area to enter the SSID (service set identifier), a name that uniquely identifies the network. • Select Infrastructure to connect to an existing wireless network, usually with an interface to a wired network, for Internet and email access, file sharing, and print and other services.
Wireless Security wireless communication standard, wireless security continues to evolve, as shortcomings of existing security solutions are uncovered and new solutions are adopted. The Airgo products provide a complete state-of-the-art security solution for 802.11 wireless networks, using the native wireless support in Windows 2000 and Windows XP where appropriate. Wireless security encompasses two major components: encryption and authentication.
3 Configuration Automatic key-generation methods rely upon digital certificates, which contain encoded user and encryption information to verify the identity of a user and match it with a database of secure user records. A certificate authority is the network service that manages digital certificates and guarantees their integrity. The IEEE 802.1X standard specifies certificate-based authentication using EAP (Extensible Authentication Protocol). EAP, in turn, comes in numerous variations.
Wireless Security Now use WZC to configure security settings: 1 Right-click the wireless icon on the system tray. 2 Select View Available Wireless Networks. 3 The window shows the list of available networks. 4 Select your network, and click Advanced to open the Wireless Network Connection Properties window, Wireless Networks tab. 5 Confirm that Use Windows to configure my wireless network settings is selected.
3 Configuration 6 Select the network, and click Configure. 7 Confirm the authentication and encryption selections exactly match those of the access point to which you are connecting. Enter a network key, if required. 8 If you selected AES for data encryption, open the Authentication tab and select the EAP type appropriate to your network. 9 Click OK as needed to close the WZC windows.

Glossary This glossary defines terms that apply to wireless and networking technology in general and Airgo products in particular. 802.1x Standard for port-based authentication in LANs. Identifies each users and allows connectivity based on policies in a centrally managed server. 802.11 Refers to the set of WLAN standards developed by IEEE. The three commonly in use today are 802.11a, 802.11b, and 802.11g, sometimes referred to collectively as Dot11.
Glossary Basic Service Set (BSS) The set of all wireless client stations controlled by a single access point. The BSSID, or identifier, for the basis service set can be assigned or default to the MAC address of the access point. Bridge A connection between two (or more) LANs using the same protocol. Virtual bridges are used as a means of defining layer 2 domains for broadcast messages. Each virtual bridge uniquely defines a virtual local area network (VLAN).
Glossary This establishes a secure channel over which the supplicant can be authenticated to the server. Extended Service Set (ESS) A set of multiple connected BSSs. From the perspective of network clients, the ESS functions as one wireless network, with clients able to roam between the BSSs within the ESS. ESSID Name or identifier of the ESS used in network configuration.
Glossary MAC address authentication Method of authenticating clients by using the MAC address of the client station as opposed to the user. Network Address Translation (NAT) The translation of one IP address used within a network to another address used elsewhere. One frequent use of NAT is the translation of IPs used inside a company, versus the IP addresses visible to the outside world.
Glossary measured, and improved. In a wireless network, QoS is commonly managed through the use of policies. Remote Authentication Dial-In User Service (RADIUS) A client/server protocol and software that enables remote access servers to communicate with a central server to authenticate users and authorize service or system access. RADIUS permits maintenance of user profiles in a central repository that all remote servers can share.
Glossary Static IP Address A permanent IP address assigned to a node in a TCP/IP network. Subnet Portion of a network, designated by a particular set of IP addresses. Provides a hierarchy for addressing in LANs. Also called subnetwork. Subnet Mask A TCP/IP addressing method for dividing IP-based networks into subgroups or subnets (compare with maskbits). Each triplet of digits in an IP address consists of 8 bits. To specify using a subnet mask, indicate the masked bits as an IP address.
Glossary or router to accomplish the same thing. Network management software of some sort is used to configure and manage the VLANs on a given network. Wi-Fi Protected Access (WPA) Security mode for wireless networks that improves on the authentication and encryption features of WEP. Wired Equivalent Privacy (WEP) Security protocol for wireless local area networks (WLANs) defined in the 802.11b standard.
