OL-1394-06

Chapter 5 Configuring the Client Adapter

Setting Network Security Parameters

• Let me give my PIN to the computer now and never ask me again; PIN will be encrypted and

stored on computer (not recommended)—You need to enter the PIN only once, in the Enter PIN

edit box below this option. The software stores the PIN in the registry and retrieves it from there

when required. If you select this option, you must enter the PIN now. The PIN is validated when an

authentication attempt is made.

Note This option is not recommended because it enables others to use the SIM without knowing

the PIN.

Step 4 Click OK twice to save your settings. The configuration is complete.

Step 5 If you are prompted to restart your client adapter, 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.

Step 6 Refer to Chapter 6 for instructions on authenticating using EAP-SIM.
