I need to create a .bat file that will set a wireless connection, eg MyNetworkName, to a public network, so it won't be on Home or Work.

I have searched and I don't know how to do this.

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form.

Your question is ambiguous - do you want to be able to switch between available wifi networks or switch an existing connection from Home or Work mode to Public mode? – Shevek Oct 3 '12 at 10:32

Note this is not a definitive solution, but something that might get you or others well underway.

Whether or not a network is public is stored in the registry, which can be edited through batch files. For a static edit, the easiest method would be to prepare a .reg-file, then merging it with the registry using the regedit command, e.g. regedit.exe /s makepublic.reg.

One of the keys involved in telling a home network from a public one, is HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList\Profiles, appended by the GUID of the network connection you wish to alter. The important values here seem to be Category and CategoryType, the first being zero for public networks and one for private networks. An example 'makepublic.reg':

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList\Profiles\{01234567-89AB-CDEF-0123-456789ABCDEF}]

Unfortunately, but not surprisingly, these values are not the only ones set by the Network Center when a connection type is changed to public and as it stands, the .reg-file is insufficient; other keys would need to be added to the list.
