Process:
: the first step is, of course, doubt yourself whether there is a network adapter and driver problem
(check card and drive a long time, the feeling is good, almost a new network card), the inspection way there are many online I will not dwell on, The second step: I repeatedly in cable and connect WIFI access web observation, I found a big problem
is under the WIFI, my network was interrupted, like, like in the same way as a request to intercept postman agent 
Step 3: start the try with a little mind bai, open the control panel, find a network share center, then find the Internet options, and find a local area network (LAN), clear the proxy IP and port, check the two box under the proxy server, OK, check again,
Wow, um,,,,, the network unlock success
Conclusion:
Encounter problems don't hurry-scurry, I doubt is network card problems from the start, all kinds of update reshipment, useless!!!!!!
There is a problem, the first rule out some physical factors, to consider other factors, more observation, if I don't see any web (have no access to the router management interface
) I wouldn't consider the question of agency, Finally, I wish you all have no bug, smooth ha ha ha ha,
