Windows 8.1 cannot connect to internet

    Question

  • I have installed Windoqw 8.1 (with Hyper-V feature) on my Win7 laptop (ASUS B43S). Win 8 is installed as a second OS, on its own partition. Things went relatively well until I tried to connect to the internet.  Using the "Manually connect to a WiFi network" Wizard, the system connects to my local network just fine, but does not connect to the internet.  To eliminate the possibility of ISP issues, I tried running the "Connect to your Internet Service Provider by dial-up or broadband".  As expected, it didn't make any difference.  I tried the "install a new driver from this computer, as suggested elsewhere in this forum.  Finally, I ran the troubleshooter wizard, which gave me the following message:

    If you're connected to a hotspot or domain network, contact the network administrator. Otherwise: 1. Unplug or turn off the device. 2. After all the lights on the device are off, wait at least 10 seconds. 3. Turn the device on or plug it back into the power outlet. To restart a router or modem that has a built-in battery, press and quickly release the Reset button.

    It seems to me that the problem has something to do with Hyper-V, but I don't have enough experience to trouble-shoot further.  Suggestions?

  • Please remove all hyper-v virtual switch from hyper-v manager console, and try connect to Internet again. You also can delete the network adapt driver from Device Manager and restart the PC for a test.

    If issue persists, collect ipconfig /all information for me.

  • Hi,

    Please be aware that this issue can be caused if the VM Network Adapter doesn't setup correctly.

    Please check following articles and try solutions there and let me know what’s going on:

    If the issue still persists, please post back the result by running “ipconfig /all” in command prompt.  

    Hope these could be helpful and keep post.

  • I'm going to try some of these fixes in Windows 8 and let you know.  Since I do not yet have a working internet connection in Windows 8,  I have to keep rebooting to Win7. 

    Whether the workaround works or not, the amount of frustration in these blogs tells me that Hyper-V just does not work in Windows 8.  Microsoft has already released a lot of Win 8.1 RTM code, and the rest is imminent.  If it goes to GA with this still broken, MS will "have a lot of 'splainin' to do"  THIS IS SERIOUS.  One more black eye could be the death of Windows 8, which would be a great pity.

    Kate, you really should escalate this to someone who can verify the 8.1 RTM before it's too late. 

    Get it together, Microsoft!
