Preserving Wireless Connections

Windows Embedded Standard includes a tool called Regpersistence.exe which is designed to configure wireless access in Write Filter Enable mode. When you configure wireless access with this utility, the authentication credentials persist across reboots, eliminating the need to re-authenticate each time the client systems are restarted. The utility preserves the service set identifier (SSID) for wireless connections across workgroup modes and domains. When Windows Embedded Standard clients restart, they are automatically connected to the desired wireless access point.

Windows Embedded Standard clients can connect to wireless networks using the following network authentication modes:

•Open mode with WEP

Note

This authentication mode requires the network key to be entered while the client is connected to the wireless network. Windows Embedded Standard clients are automatically connected to the wireless network after reboot.

•Shared mode with WEP

•WPA authentication with AES and TKIP

•WPA-PSK with AES and TKIP data encryption.

•WPA2 with AES and TKIP data encryption

•WPA2-PSK with AES and TKIP data encryption.

•PEAP authentication process

The session keys that are generated during the PEAP authentication process provide keying material for the Wired Equivalent Privacy (WEP) encryption keys that encrypt the data that is sent between wireless clients and wireless access points.

You can use PEAP with any of the following authentication methods for wireless authentication (PEAP is not supported for use with EAP-MD5):

•EAP-TLS, which uses certificates for server authentication and either certificates or smart cards for user and client computer authentication.

•EAP-MS-CHAP v2, which uses certificates for server authentication and credentials for user authentication.

•Non-Microsoft EAP authentication methods.

Note

PEAP is available as an authentication method for 802.11 wireless clients, but it is not supported for virtual private network (VPN) clients or other remote access clients. Therefore, you can configure PEAP as the authentication method for a remote access policy only when you are using Internet Authentication Service (IAS).
