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).
