Network Shell (Netsh) is a command-line utility that makes it possible to work with various server roles and operating system components in Windows, and have been available since Windows 2000. It`s commonly used to change network interface information such as IP-addresses, as well as for resetting the TCP/IP stack. For a complete overview of the capabilities of netsh, have a look at the Netsh Command Reference on Microsoft TechNet.

Starting with Windows Vista/Windows Server 2008, netsh provides commands for Wireless Local Area Networks (WLAN). This makes it possible to import and export WLAN profiles, which can be useful when re-installing your computer or maybe when deploying corporate computers where WPA Enterprise is not used.

In combination with Windows PowerShell it`s easy to import and export WLAN profiles using netsh. I`ve provided a script containing two PowerShell functions:

• Export-WLAN
• Import-WLAN

The script is available here.

Note that Windows Vista/7 has a concept of all-user and per-user WLAN profiles:

All-user profiles is the default, and the functions are not customized to work with per-user functions.
