The computer can t get on the Internet, it s not the cat s problem, it s not the network cable s pro

Generally in the local area network, there are several possibilities for those who cannot access the network:

1. Internet Explorer has been maliciously modified.

2. IP address conflicts.

3. The network cable interface is loose.

4. System problems.

The above situations are my experience when I was working as a network administrator, and 80% of the 4 possibilities are that the Internet Explorer has been maliciously modified. 10% are address conflicts. 5% is the loose network cable interface. 5% is a system issue.

When you can access the Internet, you ping the dns of the telecom to see, whether there is a drop in the line, you can not access the Internet when you dial, see what appears**, 678** is generally a problem with the cat, or a problem with telecommunications, if not, you can change the broadband password, now there are a lot of people who steal broadband, maybe you can solve the problem, or change the network card to try.

First look at my computer right-click has a property -> hardware-> device manager,See if the network card driver is installed,If there is no next driver installed,If the network card driver is installed, you will change a network cable,If the network cable is good, you can only change the network card。

This may be a problem between the slot of the motherboard and the network card, try to clean up the gold finger of the network card and change the slot, or if it doesn't work, change the network card, and then it will be the motherboard.

It is recommended to change the attributes of the network card, click the network neighbor attributes, then click the local connection attributes, click the configuration, and then in that auto....Try to change him to a 10m one.

There is a network on the connected cat, a router wifi has a network, and the computer network cable has no network.

1. First of all, make sure that the network cable is connected correctly. That is, the network cable from the external network is connected to the WAN port of the router or the cat, and the network cable of the computer is connected to the LAN port. 2. After the network cable is connected correctly, be sure to set the correct Internet account and password in the router WAN settings.

3. When the WAN connection is correct and the account is configured correctly, you can check the running status of the WAN port in the "Running Status". If you get a DNS server, it's fine, otherwise there's a problem. 4. After the network connection between the router and the service provider is successful, if there is still a problem with the network, it is a computer problem.

5. First of all, the router needs to enable the DHCP service. On the left, select DHCP Server, and then select DHCP Service. 6. Set the "DHCP Server" on the right to "Enable".

7. Then, when setting up the wireless, it is recommended to set the wireless channel to the commonly used, and then restart the computer after leaking lead.
