If a DHCP server is not found, it automatically configures an APIPA or alternate address.For Windows 2000 Service Pack 4 (SP4) or later or Windows 2000 Service Pack 3 (SP3) with Microsoft 802.1X Authentication Client, use the Ipconfig tool to display the adapter status and IP address configuration for the wireless network adapter.

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.When you repair a wireless connection, it is disabled and re-enabled, which clears many error conditions on wireless network adapters.When a wireless client running Windows XP with SP2 or Windows Server 2003 with Service Pack 1 attempts a wireless connection, it goes through the following authentication states, which are indicated as the status of the wireless connection in the Network Connections folder, and in the new wireless connection Status dialog box, and in the Wireless Network Connection dialog box: Once authentication has succeeded, a wireless client running Windows XP with SP2 or Windows Server 2003 with Service Pack 1 then attempts to obtain a valid IP address configuration and goes through the following states, which are indicated as the status of the wireless connection in the Network Connections folder, and in the new wireless connection Status dialog box, and in the Wireless Network Connection dialog box: These improvements give the user and the network troubleshooter more information about how the wireless connection is progressing, from the initial association to the allocation of a valid IP address.This article assumes background knowledge in IEEE 802.11 wireless LAN and associated security technologies and the components of a Windows-based authentication infrastructure.For background information, see Wireless LAN Technologies and Microsoft Windows.To obtain detailed information about the Wireless Zero Configuration service for Windows XP SP2 or Windows Server 2003 with Service Pack 1 and the EAP authentication process for all versions of Windows XP or Windows Server 2003, you must enable tracing by typing netsh ras set tracing * enabled at a command prompt.

To obtain detailed information about how the Wireless Zero Configuration service connected to a wireless network for computers running Windows XP with SP2 or Windows Server 2003 with Service Pack 1, try the wireless connection again and view the and files in the \Tracing folder.

If the wireless adapter has an Automatic Private IP Addressing (APIPA) address (169.254.0.0/16) or the configured alternate IP address, then authentication has failed and the Windows-based wireless client is still associated with the wireless AP.

If the authentication fails and the association is still in place, the wireless adapter is enabled and TCP/IP performs its normal configuration process.

For detailed information about a Windows-based authentication infrastructure, see Wireless Deployment Technology and Component Overview.

For detailed information about how to deploy a wireless LAN using IEEE 802.1X authentication, see Deployment of Protected 802.11 Networks Using Microsoft Windows.

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.
