Ah, maybe I answered the wrong question -
The WIFI_NO_NET_PROBE **will not** prevent the Kindle from accessing the Internet.
It only prevents the WiFi from failing if it otherwise can not access the Internet.
To use the WiFi on the Kindle **without** connecting to the Internet, you will have to block its Internet access in your access point or router.
= = = =
For instance, my router can filter on MAC addresses, and the filter is set to block the Kindle from accessing the Internet by its MAC address.
At least for some of my Kindles others just stay in 'Airplane mode'.
The week or two wait for the 'closed Kindle' jail break release will give you time to read all of the threads about using the Kindle as a remote computer screen.
