Chapter 6 Using EAP Authentication
Using EAP-SIM
If You Are Prompted for the PIN
If you chose to be prompted for the PIN after a power-up or reboot or at every authentication request,
follow the steps below to EAP authenticate.
Note These instructions are applicable after profile selection, card ejection and re-insertion, reboot, or logon.
Step 1 Perform one of the following:
• If your computer is running Windows 2000, the Enter PIN screen appears (see Figure 6-16).
• If your computer is running Windows XP, a pop-up message appears above the Windows system tray
informing you that you need to enter your credentials to access the network. Click this message. The
Enter PIN screen appears (see Figure 6-16).

Step 2 Enter your PIN and click OK. The computer now retrieves information from the SIM card. If you enter
the PIN incorrectly, an error message appears.
Note If you exceed the maximum number of retries for entering the PIN, the card locks up.
Step 3 The client adapter should now EAP authenticate. To verify authentication, double-click My Computer,
Control Panel, and Network Connections. The status appears to the right of your Wireless Network
Connection. Click View and Refresh to obtain the current status. If the client adapter is authenticated,
the status reads Authentication succeeded.
Note ACU and the Windows Wireless Network Connection icon in the Windows XP system tray may
indicate a connection status when authentication is still in the pending state or the authentication
server fails to respond.
