I just uninstalled AVG but still have the same problem. My HP Laptop is running Windows 8. IE, Netflix, and other APPS that require internet work fine from the APPS page, but once I open Desktop no Internet access using any program, IE, Mozilla, TeamViewer, etc.
First, this has absolutely nothing to do with IPv6, which by the way, always says no internet access because it's only used internally with Windows at this point. Do not ever disable IPv6 as there are components in Windows that rely on it's functionality.
This problem is usually from either Winsock or the TCP/IP stack requiring a reset which is a very common problem.
Run the following two commands one at time, use an elevated command prompt, hit enter after each command "in bold". Then restart your machine.
