In the ordinary process of surfing the internet often occur a variety of network failures, resulting in the Internet, this is the most depressing time. But to keep calm, in fact, as long as you carefully follow the steps described below to check, the problem is not difficult to solve.
1, first check whether other people can surf the internet, to determine whether the entire network has a problem. If other people can not access the Internet, check the hub, switch, or fool-like small routers are working properly. The main observation is whether their LEDs are lit. When all these devices are OK, check to see if your cat is working properly.
2. When you are the only one who cannot access the Internet, right click My Network Places to see if local Area connection is connected properly. If there is a fork, it can be judged that the network is not connected well. At this time check the RJ-45 interface (NIC interface) is loose, again plug again. If not, check if the network interface with the hub or switch is loose.
3, if you do not see the "Local Area Connection" in the above steps, then right-click on "My Computer"--> "management"--> "Device Manager" to see if there is a "network adapter", if not, you can be judged that your network card is broken, bad contact or the network card is oxidized. Solution: Take down the network card, with an eraser, and then reinsert, repeat the inspection method mentioned above, if not, then replace the new network card.
4, open "Run"-->cmd, in the CMD window, enter "Ping native IP address", such as not general network card problems, it can be a NIC driver is not installed.
5, continue to enter the cmd window "ping other host IP address" can not be the general rule is your IP address settings have problems, reset IP address. Workaround: Right-click the Network Places--> property, double-click the local Area Connection--> property--> Internet Protocol (TCP/IP)--> properties to configure the IP address, gateway, DNS server.
6, must ensure that your IP address and other people's IP address is different, otherwise there will be IP address conflicts, but the gateway to the same, DNS server the same.
The above is I encountered in the work of some of the network troubleshooting solutions and solutions, find the right method, I think you will succeed in half. Then in the process of looking up the problem to pay attention to a few small details, I think when you read this article, there is a network failure you will not be alarmed. Take care of it, 3 minutes!! Oh!
