There are many reasons why Ethernet still can't access the Internet. The specific solutions are as follows:
First, check the network cable.
Make sure there is nothing wrong with the network cable. If there is a big red cross on the network icon in the lower right corner, first check whether the network cable is plugged in. If the network cable is plugged in and works normally, the yellow light will always flash next to the place where the desktop computer is plugged in and the laptop computer is plugged in. If the indicator light doesn't flash, it means that the network cable is not plugged in or plugged in, and it doesn't work.
Second, get the IP address information again.
When the network can't connect, the first thing that comes to mind is to check your own IP address information. We can enter ipconfig or (ipconfig /all for details) at the command line (cmd) to view it.
If we get the IP address of the normal network segment of our company, or the IP network segment set by the router at home, this is normal. If the IP address information is not the network segment set in your own environment, this is an abnormal situation, and you need to reset the IP or get the IP address again.
Third, diagnose the network connection.
To solve network problems, there is a good tool in Windows called "Windows Network Diagnosis", which can help us find out the causes of some problems. Turn on the network adapter of our computer. If the laptop is wirelessly connected to the network, it will open our wireless network adapter. At this time, you can click "Diagnosis" on the lower right to open the "Check" of Windows network diagnosis:
A wizard will pop up for automatic diagnosis. In some cases, it will be repaired automatically, and some problems can be solved by using Windows diagnosis.
If related problems are detected, they can be repaired according to the problems found.
Fourth, broadband connection.
If the broadband connection is not normal, you may not be able to connect to the network. The solution is to open the control panel-Network Connections, find the current local connection, right-click, select Properties, double-click Internet Protocol (TCP/IP) in the General tab, and choose to use the following IP address. Generally, fill in "192.65438" in the IP address. If the problem is not solved, please note that IP must be on the same network segment as the IP address of ADSL modem. If the current computer joins a workgroup or domain, it should be set according to the situation. Sometimes, you can delete the "Notify me when this connection is restricted or disconnected" option from the "Properties" of the local connection of the network connection.
Verb (abbreviation of verb) network card driver
When upgrading from Windows7 to Windows8, sometimes the network connection will be limited or unable to connect. At this time, it is necessary to ensure that the driver of the upgraded network card is correct.
Six, network operators
When you can't get online, you might as well call the operator of your choice. It is also important to remember all kinds of codes, such as 65 1, 678, 69 1, when you can't access the internet or have problems with dialing, which are important basis for us to troubleshoot.
