I have my new Surface Pro 3 for over a week now. I love this device. Indeed it is a very nice piece of hardware and in my case, a great notebook replacement. With all the accessoires I never miss my notebook. Visual Studio 2013 runs smooth and great which was one of the most important points. There was just one annoying point until now which was kinda… confusing. After restarting the machine from sleep my WLAN was limited and no connection could be established. I’ve read through some blogs on the web where users reported similar issues. In my case only a restart helped. In my case that was caused by Hyper-V installation and activation which came with the Visual Studio installation.
You can find detailed information in this article which helped me a lot: Winsupersite Surface Pro 3 Tip
They explain in detail the cause and a fix for this. In fact the fix is currently to disable Hyper-V as long as it is not used and enable it again when needed. Since most of the time I’m working on web and app development instead of Windows Phone this is totally OK for me. Here are the magic lines from the article above (don’t forget to use the command prompt in admin mode):
bcdedit /set hypervisorlaunchtype off
bcdedit /set hypervisorlaunchtype auto
As the article states a restart might be required. This solution works fine for me but surely I hope that Microsoft will be able to fix this issue in future updates.
