Error message when you use SmartCard-only authentication to log on to a Windows Vista-based client computer in a wireless network environment: “Cannot connect to [SSID]: Please contact network administrator”

Consider the following scenario:

  • Your computer is in a wireless network environment that uses Extensible Authentication Protocol-Transport Layer Security (EAP-TLS).
  • You use SmartCard-only authentication for the wireless connection authentication.

In this scenario, when you log on to a Windows Vista-based client computer, you may receive the following error message in the toolbar:

Cannot connect to SSID: Please contact network administrator.

Note: In this message, the SSID placeholder represents the wireless network connection.

Therefore, you cannot connect to the wireless network. In this case, you must manually reconnect to the wireless network.

This problem does not occur when you log on to the computer for the first time. When you log on for the first time, you receive the following message:

Wireless Network Connection:

Please click here to select the certificate for the following network connection or other qualification information.

After you provide the correct information, you can successfully connect to the wireless network.

Note: This problem does not occur in Windows XP. In Windows XP, you are prompted to provide the related smart card information. Then, you can successfully connect to the wireless network.

There is a download that resolves this issue. See Hotfixes for details.
