I've been using my Mainstage adapter to watch movies successfully for a long time and now it isn't working.
I updated a few drivers a month or so ago to resolve some other issues and while I'm sure I tested WiDi it isn't picking up the adapter now.
So I ran the Intel Driver Update Utility and performed the updates it recommended, but still with no luck. I also first updated my graphics driver from the manufacturer website (Intel HD Graphics 3000 version 8.15.10.2418).
I updated to ProSet/Wireless version 16.6.0 which I understand was supposed to automatically install My WiFi Dashboard but it didn't. I found a recommendation to click on Change in Windows Programs and Features to enable installation of My WiFi Dashboard, but it only provides 2 options - repair and uninstall, which suggests a problem. I get the same results after multiple successful Repairs and reinstalls.
I manually installed My WiFi Dashboard as it seems to be a requirement and it replaces My WiFi Technology. The latest available version was 15.06.0 and it installed the Lite version. I see a requirement for the version to match that of ProSet/Wireless so maybe this is an issue, although I can't find a higher version. If I click on My WiFi Dashboard in Windows Programs and Features it also displays a Repair option, which also ran successfully but continues to display as an option.
I updated WiDi to 4.2.21. I can run the application but the scan does not detect the Mainstage adapter. I can bring up My WiFi Dashboard but it displays the message that I need an upgrade ("This computer is capable of using Intel My WiFi Technology, however a supported version of the software is not installed").
I am at a loss and looking for help.
