Cannot connect through wireless after Windows 8 upgrade

    Windows 8


    Didn't have any problems signing on with a computer on a domain ever before. I did find something very interesting this morning though. I turned on the Hyper-V feature and configured an "External" Virtual Switch to use the host OS network card. Suddenly, communication with the router ceased (or started timing out to be more accurate) when on the wired connection. And miraculously, the wireless now worked with no hitches. This was odd; so to experiment more, I went back to Hyper-V manager and reconfigured the virtual switch to use the wireless network adapter instead of the NIC. Sure enough, the problem switched back over to the wireless adapter (communication being suppressed when on wireless connection). Next experiment, I changed the virtual switch to an "Internal" type. Now, both the wired and wireless connections work just fine. The only inference I can make (at least since I turned on Hyper-V) is that whatever underlying adapter the virtual NIC happened to leverage was hampered (can't think why or probably don't understand Hyper-V deeply enough). I still have no idea why the problem existed before I turned on Hyper-V. Just very confused at this point.

    If I knew there was a virtual switch involved I would have instantly placed the blame firmly on that. Been there done that.
