Hi Joe,
Being that we have up to 50 users per computer, of which there are 16,000, there is a lot of wasted time in our organization having to click the hotspot assistant. Your solution would have each user click multiple times to disable a feature that requires only one click to dismiss and not come up again. We are going in the opposite direction.
Fortunately I have a contact from dell who provided this working solution. If you add HOTSPOT=DISABLE to the properties section of setup.xml, it seems to disable this feature and not ask any questions of our users. This is the final solution we came up with to make intel WiFi cards work correctly with Cisco access points and not bother our users.
