Error Messages
Error Message For the changes to take effect, please restart your WLAN card (or your
computer) NOW.
Explanation
The changes you made on the SIM Authentication Properties screen can take effect only
if you perform a complete reauthentication. Otherwise, your wireless network connection may
appear to be stuck in the “Validating identity” state.
Recommended Action Turn off your client adapter’s radio, wait a few seconds, and then turn the radio
back on. Refer to the “Turning Your Client Adapter’s Radio On or Off” section on page 9-15 for
instructions.
Error Message GetUserPin returned error.
Explanation
Windows encountered an error while prompting for or retrieving the PIN.
Note The eight-digit hexadecimal error code in the message may assist technical support in
troubleshooting your problem.
Recommended Action Wait until the system tries to authenticate the client adapter again
(approximately 30 to 60 seconds) and enter a valid PIN. Do not click Cancel or otherwise interfere
with the normal operation of Windows. If the problem persists, reboot your computer.
Error Message Maximum length of PIN is 8 characters.
Explanation
You tried to enter a PIN that is longer than eight characters. SIM card PINs are restricted
to a maximum length of eight alphanumeric characters.
Recommended Action Delete one or more characters from the PIN field or delete all of the characters
you entered and retype the complete PIN.
Error Message Network authentication aborted.
Explanation When you were asked to enter a PIN, you clicked the Cancel button and cancelled the
authentication process. The EAP-SIM supplicant will not attempt to authenticate to the network.
Note The system will try to authenticate automatically within 30 to 60 seconds.
Recommended Action If you want to authenticate to the network and establish a wireless network
connection, enter the valid PIN for your SIM card. If you do not want to establish a connection,
consider turning off or ejecting the client adapter; otherwise, the system will reprompt you every 30
to 60 seconds.
