When i open a new Unity 5 project i get the error: "Socket: bind failed, error: An attempt was made to access a socket in a way forbidden by its access permissions. (0)" And then my internet drops. (I still have a network connection but all internet connected apps get disconnected and my browsers gives a error when i try to browse). 15 seconds after i close Unity, my internet works again. Should be noted that Unity 4.x works perfectly on my machine.
