So I also keep Baidu, the answer is probably some try the answer is not effective, probably hook off the IPv6, or in the top of the hook to something, are not said the midpoint of the answer.
So how to get rid of this automatic configuration IPv4 this culprit.
later by sister accidentally tried to modify the local IP, incredibly found to be able to surf the internet, and Ipconfig under the normal, automatic configuration of the IPv4 disappeared. Later sister understand come, in fact, is the local IP address and LAN someone set up the IP conflict, as long as we bypass reset a new IP on OK, and we are thinking how to remove automatic configuration IPv4 on the detour.
summed up, in the resolution of the problem can not be a hit in a corner of the dead in the turn, perhaps out of the question, in fact, after the detour.
