Fixed – wifi not resolving dns on laptop with Windows7

I had a strange case the other day at work when all of a sudden my laptop would fail to resolve dns queries for my wireless connection only – my wired card was not affected. Changing dns entries to another server did not fix the issue. Eventually I tried disabling the Microsoft Virtual Wifi Miniport Adapter (from device manager) and immediately I was able to resolve dns again. Once I discovered this fix I remembered something similar with this adapter. Looking back through my previous notes we had an issue with Shrewsoft’s vpn software – with the Microsoft Virtual Wifi Miniport Adapter enabled we were unable to get a vpn session working to a Cisco client.
So far, disabling this adapter does not seem to have caused any issues – apparently it’s purpose is to allow you to connect to more than one wireless connection at the same time – an unlikely requirement in most business situations.

    Not sure why this causes problems. Would be interested in finding out. I was having the same problem and this fixed the problem. Thanks!
