Troubleshooting Tools in Windows Wireless AP Troubleshooting Tools IAS Troubleshooting Tools Troubleshooting IAS Authentication and Authorization Summary Related Links The tools for troubleshooting wireless connections in Windows XP and Windows Server 2003 are the Network Connections folder and tracing.
This article assumes background knowledge in IEEE 802.11 wireless LAN and associated security technologies and the components of a Windows-based authentication infrastructure.
Abstract This article describes the tools used to troubleshoot a Microsoft Windows XP or Windows Server 2003-based wireless client, a wireless access point (AP), and the Internet Authentication Service (IAS) when using Institute of Electrical and Electronic Engineers (IEEE) 802.1X authentication for IEEE 802.11-based wireless connections.
This article also describes the most common problems with IAS authentication and authorization, certificate properties, and the process of certificate validation for both wireless client and IAS server certificates.
Within the Network Connections folder, the text under the name of the connection corresponding to the wireless network adapter indicates the status of the connection.
Figure 1 shows the information available for a wireless connection in the Windows XP Network Connections folder.
When you repair a wireless connection, it is disabled and re-enabled, which clears many error conditions on wireless network adapters.
