Obtain a Client Authentication Certificate

To secure your WLAN connection you need a certificate approved by a Certificate Authority. Both WLAN client and RADIUS server must use a trusted Certificate Authority. Make sure to use a certificate request template for Client Authentication.

Cryptographic Service Provider selection:
During certificate request you need to select the Cryptographic Service Provider to be used by your certificate.
  • If you want to authenticate yourself, select a User CSP (Infineon TPM Cryptographic Provider or Infineon TPM RSA and AES Cryptographic Provider).
  • If you want to authenticate your computer, select the Platform CSP (Infineon TPM Platform Cryptographic Provider).
    To use the Platform CSP, you must be an administrator or a member of the Administrators group.

Set up the WLAN Software

Please refer to your WLAN vendor's documentation regarding the overall WLAN setup. Your vendor's software may include a client software to configure WLAN connections.

You can also use your operating system's Network Connections to configure WLAN connections:
  • Configure a wireless network connection on your WLAN client as described in the Microsoft Windows Help (search for "wireless networking").
  • Make sure to use the following Authentication settings:
    - Select Enable IEEE 802.1x authentication for this network.
    - In EAP type, select Smart Card or other Certificate.
    - In Properties, select Use a certificate on this computer.
    - If you want to select the certificate each time you are starting a wireless connection, then uncheck the option Use simple Certificate Selection.
