The computer network connection is normal, the sending and receiving data is 0, and a line of Window

If you confirm that it is not a virus problem, you can see whether the data in the DNS option under the IP protocol is correct, if the MAC address can not be seen, you can consider reinstalling the network card, if you do not want to reinstall the network card, you can first disable the network card and then restart the machine, and then enable the network card. If this still doesn't work, you can use 360 or software tests such as Optimizer and Master Lu to fix it.

Enter cmd first

Then enter ipconfig all in cmd

First of all, let's talk about the local connection, when the system is normal, a local connection corresponds to a network card. So the average personal PC has only one local connection.

In addition to the local connection, the laptop also has a Wi-Fi connection, so it is normal for the laptop to have two connections.

Up to 3 local connections will be used, IP4 local connection, IP6 local connection, and wireless connection.

Redundant local connections, including IPv6 connections, can be deleted, as they are rarely used! Only one IPv4 connection is left, and if the wireless connection is not used frequently, it is recommended to disable it!

Well, the win7 system is like this. This is true for all of our company's notebooks. There may be fewer desktops with win7.

IP address is automatically obtained, subnet mask; Gateway Preferred Alternate DNS is obtained by entering ipconfig all.

Then the last digit of your local machine is set to not 1, and the gateway is changed to just that, and the subnet mask is correct.

I would like to know what brand of router your company uses? Is it a wireless or wired router? You said that you can surf the Internet with this IP?

This IP is generally the gateway of the router, how can I be set as an IP address? Then you said to set the same IP for the wireless, of course this is not possible, it is not allowed to have the same IP on the local area network, please complete the question and then answer.

The IP protocol is set to.

dns set.

2--254: It's best to see if the IP of the other 2 machines is not the same, and it is a problem that DNS is not set to connect to the Internet.

Win7 wireless network shows that it is connected but cannot be connected to the network, and there is a solution to a yellow exclamation mark.

If you go online in the company, you can set up automatic IP acquisition, or you can see how the DHCP server is configured and then set the IP, or you can't afford to access the Internet.

In this case, you may need to check the environment variables.

My computer right--Properties-Advanced-Environment Variables-System variables, check if the path variable has %systemroot% system32, if not, add %systemroot% system32;

After you are sure, reopen -cmd and run ipconfig all to view the IP information.

Slash Written incorrectly...

ipconfig all is slanted to the left...

What does it mean to take a picture?

This is to check the IP configuration information command, if not, it is estimated that the network card driver is not installed or broken.

The NIC driver is installed incorrectly.

I have encountered a similar problem, and the system shows that the network card is normal after the driver is installed!

The final solution is that the network card really does not match the brand model!
