Windows 7 DNS Not Resolving: WiFi Miniport Adapter Issue

I had a computer running Windows 7 that had an odd issue with the DNS would randomly resolve and then other times it wouldn’t.  I wasn’t using a local DNS server, it was the ISP’s and the DNS would resolve perfectly fine on other computers.  It took me a bit to figure out that this was what was causing web pages to only intermittedly load, but once I figure it out a quick search on google turned up someone with the same problem.  The solution that worked for us was to disable the Virtual WiFi Miniport Adapter.  You can do this by going to Start -> Control Panel -> Network and Sharing Center -> Change Adapter Settings (on the left sidebar) and then right click on the Miniport Adapter and click disable.  Your DNS should start resolving without issue (hopefully).
