Windows 7 network settings profiles

I would like to have various "profiles" for my network settings -- one for work, one for home network, etc. Changing a "network profile" would change my IP address and DNS server address for a network adapter, and if possible add or remove a route.

Is there some free software for that purpose?

Here are some free products that can switch between configurations for network settings, including even printers and shared folders :

Eusing Free IP Switcher
NetSetMan

TCP/IP Manager seems to satisfy the reqirements. Netprofiles also seems to work, but just for LAN connections under Windows 7. Netprofiles could not start on Windows 7 x64
