Have you tried using Windows Wireless zero configuration, or also knows as Wireless auto configuration?
actually not, because I like ProSet und would like to use it further. When there is no way to make ProSet show me the button for "Device to Device (ad-hoc)", then I may think about it. That's why I came to the intel forum.
I am sorry, the best suggestion is using Windows* Wireless Zero Configuration since newer Intel® Proset versions do not support such option anymore.
Please note the available user guide(s) were published for older software versions.
I apologize for the inconvenience.
