First of all, I would like to say that as a student who has just finished the computer network class, and also finished the school's alleged and Stanford a difficulty level of the network experiment. I feel I'm barely getting started with the computer network. All kinds of TCP, HTTP, routers, switches, local area networks, WAN, etc. have been clearly understood, but ... Sure enough, the theory is still to combine actual combat, especially in today's complex multi-terminal network world of practical experience decisive important ah Ah.
Well, forgive me above the title of the BB, due to the computer appeared this problem. What I have learned is to use all the possibilities and solutions that I can think of. I have a feeling of being out of my wits ...
Been tortured for a very long time, just, just.
At last it was conquered, so here's a way to talk about my solution. In case someone has the same problem as me, don't be tortured so much. Because most of the online methods are still eggs ah.
。
My Computer system is win8, the problem arises:
1, plug the network cable, the Internet center shows Internet access. Can access through the campus network of Ruijie Login
2, TCP set their own initiative to obtain an IP address, their own initiative to obtain dnsserver and alternative dnsserver address
3, through the query network specific information, display IP address, dnsserver address to obtain the correct
4, DNSServer is available. Confirmed by the roommate's computer.
5, using the cheetah free WiFi diverging WiFi, the spread out of WiFi is able to connect to the network
6, Ping gateway, pass; Ping DNSServer, pass. Ping www.baidu.com directly, pass
7, the computer steward measured the speed. can be measured by
8. Proxy Server Disabled
But
But
1, a variety of browsers do not open
2, QQ login not on
3, the use of other applications on the computer is indicated. Network Connection Failed
、、、、、、
So, it started a variety of attempts.
1, somehow, the first reaction is to restart the computer, and then the egg
2, the Network Center TCP settings confirmed several times, and then the egg
3, manually set DNSServer, choose different DNSServer try, and then egg
4, computer butler, network repair, and then eggs
5, cmd Input command: Ipconfig/flushdns. And then the egg
6, remember the previous update of the computer. A recent update was uninstalled, and then the egg
7. Control variable ~ ~ ~ I can't connect my wifi, but my eggs
8, all kinds of Baidu, try a variety of programs, and then eggs
9, crazy.
。。 And then the egg
10, finally,. Finally found a command (there should be flowers applause):netsh winsock reset
The Winsock is restored to its default state and then restarted. Decisive connection to the net, so the computer appears above the phenomenon of the reason is very obvious, the computer system internal folder Winsock was changed, resulting in network configuration error, so even if the computer settings are not wrong. However, when Winsock transmits information to the network connection, the parameter changes, resulting in a failure to get the correct response. Nor does it make the right request.
Before the network programming is not associated with the system, directly is the implementation of the principle, so for the Windows network programming interface has not touched, through this time know that the Windows Network programming interface is Winsock. The reason why this command is practical is because through the above analysis of the various tests indicate that my computer is not connected to the Internet. Unrelated to the network, router-independent, and DNSServer, independent of various networking settings on the computer, and system-independent. So my guess is that some of the malware that I've been installing has changed the number of participants so I don't even have access to the Internet, but I didn't install any software when this problem happened. Just uninstalled a few, among them: Itudou, potato video, Storm audio, Chrome browser.
。 I don't want to study any of the changes. It's just. Sister can Ann you can not unload you!! The Wisp!. Really deserves the name of rogue software, inexplicably let people waste so much time and energy to find problems, although they will do it this line, but must remember to adhere to the moral bottom line, relying on technology to win applause and not other things
Windows can connect to the network, but cannot open the Web page, the DNS of the server cannot be resolved
