Ok.. I installed and it worked right away for about a day and a half and then I wound up here as well. Yes it is annoying that it quits working but all I had to do to get going was
1. control panel - network and sharing center - (left panel) change adapter settings.
2. find connection that says Microsoft Virtual WiFi Miniport A.. -right click on it and press disable. (Take note of connection number) - close window
3. double click on your current connection you use to go online. - click sharing tab - make sure share connection is enabled. - if it already is uncheck and recheck box. - close window.
4. right click on Microsoft Virtual WiFi Miniport A.. once more and click enable. - close all windows
5. open virtual network. - choose the Microsoft Virtual WiFi Miniport A..as the network to share. should be the highest number network for most people.(connection number for you can be noted in step 2. if you forgot or didnt read all of this before doing these steps.....)
6. click connect and see if you have access to the internet once more. I can find more solutions to this problem as well if anyone needs. just let me know.
7. When it happens again now you know. - hope that helps - www.thelinuxmotion.org
