1 Introduction 1.1 Overview The Madge advanced Smart Wireless Access Point (advanced AP) enables IEEE 802.11b client computers to access the resources on an Ethernet network. Because it supports IEEE 802.1x and RADIUS (Remote Authentication Dial-In User Service) for user-based authentication and dynamic encryption key distribution, it is suitable for enterprises that need strong data security and WISPs (Wireless Internet Service Providers) that need accounting and billing support. In Sect

2.3 Preparing for Configuration For the user (or administrator) to configure an advanced AP, a managing computer with a Web browser is needed. For first-time configuration of an advanced AP, an Ethernet network interface card (NIC) should have been installed in the managing computer. For maintenance-configuration of a deployed advanced AP, either a wireless computer or a wired computer can be employed as the managing computer. NOTE: If you are using the browser, Opera, to configure an advan

2.4 Configuring the Advanced AP After the IP addressing issue is resolved, launch a Web browser on the managing computer. Then, go to “http://192.168.0.1” to access the Web-based Network Manager start page. TIP: For maintenance configuration of an advanced AP, the advanced AP can be reached by its host name using a Web browser. For example, if the advanced AP is named “advanced AP”, you can use the URL “http://advanced AP” to access the Web-based Network Manager of the advanced AP. 2.4.1 E

1. Launch the configuration/monitoring utility provided by the vendor of the installed WLAN NIC. 2. Check if the client computer is associated to an access point, and the access point is the advanced AP. If the check fails, see Appendix B-1, “Wireless Settings Problems” for troubleshooting. 2.7.2 Checking if the TCP/IP-Related Settings Work To check if a client computer can access the Internet: 1. Open a Windows Command Prompt window on the client computer. 2. Type “ping advap”, where adva

The IEEE 802.1x functionality of the advanced AP is controlled by the security mode (see Section 3.4.2). The advanced AP supports two authentication mechanisms—EAP-MD5 (Message Digest version 5) and EAP-TLS (Transport Layer Security). If EAP-MD5 is used, the user has to give his or her user name and password for authentication. If EAP-TLS is used, the wireless client computer automatically gives the user’s digital certificate that is stored in the computer hard disk or a smart card for authe
