I have no internet access on my Windows Phone 8emulator that I run in Windows 8 through the Visual Studio 2012. I know this because for one, I cannot open any website in the Internet Explorer within WP8 emulator.
The desktop on the other hand (on which the Windows 8 is running) has Internet access (I can browse websites without any problems in Windows 8). So, I have internet in Windows 8 instance I’m running, but I don't have in the Windows Phone 8 emulator that is run on that OS.
I don’t have any router in my home. I have the ethernet cable that I got from my internet provider connected directly to my network card in my PC. My IP is set staticaly, and is public.
Now all I did so far, was open Visual Studio and run an emulator. Once it loaded, I quit my mock application, picked Internet Explorer tile and tried to open couple known websites, all failed to load. I did not change any settings in an emulator, nor did I do anything else with the emulator image.
What I expected, was same behavior as with Windows Phone 7 (7.0 and 7.1) emulator. I ran emulator and I had instantly internet access on it, as long as my desktop internet connection was working. Here is not the case.
I would like to repeat one thing. I don't have a router. I did not change any settings in Windows 8 concerning network, all I did was run emulator and notice that it doesn't have internet access within it.
