You might want to try disabling the Msoft virtual mini port adaptor then test to see if the problem persists. It may also help to stop using the shared wireless network with the following command.
Stop the wireless hosted network:
netsh wlan stop hostednetwork


If you still need to use the virtual mini port for the shared wireless connection you can always enable the virtual mini port again if you need it. Connectify has decent software for setting up a shared wireless connection. You can also use the manual method which is outlined in the following link.
