In schools or in some cases where a LAN is made up of a switch router, some computers will not be networked if a power outage occurs. Let's talk a little bit about the solution
Steps/Methods
Such a failure of the network generally does not appear all the computer can not be networked, so first you have to go to the network of people's computers to obtain IP address. First into the Control Panel
Select the network connection option.
Double-click on the local connection to view the tab.
The contents of the tab are as follows, and we can see the IP and gateway in the support. We will then follow the above method to enter your own computer's local connection, select View Properties
And then the Properties Pop-up dialog box, select the IP option
The next thing you need to do is to fill in the IP and gateway address you copied. As for the DNS server address I'll tell you a better address is 8:8:8:8. The final click is OK.
Tips: The above problems are relatively common also relatively good to solve, encountered a router restart to cause the network connection can not be hurried to follow the steps of the above procedures to try it!
