Ping the network after touching your finger

In Runtime, enter ping -t or any **.

You can ping a ** at will, if the return is not time out, it means that the network is open, and you can surf the Internet.

2. Win7 can also find "Run" in the attachment, enter cmd, and press enter to open the command line. The XP system can be found running in the start menu, enter cmd to enter the command line.

3. After entering the command line, you can directly enter the ping command, for example, to check whether you can access the Internet, you can enter it.

4. If the current network is connected normally, the following information will be displayed, and there will be no data loss. If the current network cannot be reached, the request cannot find the host. If you want to check the current network communication, you can enter "ping -t" to hit enter, and it can continue.

5. Test the network status. The following information is displayed on the network, and there is no packet loss. If the network is unstable, a request timeout occurs, indicating that the network speed is too slow, and the network cable port or switch port may be faulty.

If there is a "general fault", it may be that the network cable is not plugged in properly. After the network is configured or just connected to the network cable, it is useful to use the ping command to test the network.

First ping for the local test, if you pass, it means that your system settings are normal, ping the local IP to see if the network card is normal, and then ping the gateway, if you pass, it means that your computer to the gateway is normal. Ping local routing IP communication side system settings network card crystal head network cable routing are no problem ping external network IP general means that you can access the Internet, if not, you have to call Unicom**, and report for troubleshooting.

Start Menu - Run - Enter cmd - Enter ping IP, there is a space after ping.

Is your ping address intranet?

There is no such legal address on the Internet! So it definitely doesn't work!

The packet didn't go out, a loop was formed, try it with tracert.

tracert

Isn't that ping? lost = 0.

First, make sure that the network is connected. Second, make sure that it has enabled the ping service, not only the computer in the computer room has the ping service, but also the firewall and router connected between the computer room computer and the external network must also trust the ping service. Third, you need to make sure that the IP of the computer in the computer room you know is a real IP or an IP that has been converted by the router to trust the external network, which is the key.

If this still doesn't work, it depends on the situation.

If the computer in the student computer room is equipped with a private IP address, you can't ping.

i.Student dormitories, you can ping the address of its gateway IITo check the mail host, you can enter .

replay from : bytes=32 time=2ms ttl=254b.To close the screen, press the Ctrl - C keys 4...

Program execution screen (2) aIf there is a problem, there will be different messages as follows, and the reasons for this are:

iii.destination is offline.b.

To close the screen, press the Ctrl - C keys 5Application of ping aSituation 1 The use of the school Internet service is suddenly interrupted For example, even the beautiful girl suddenly disconnected, but it is usually normal because other ports on the same set of hubs as you suddenly have a large number of transmitted data and grab a large amount of bandwidth, and you are crowded.

At this point, you can ping a host on campus, and his response will be intermittent, maybe five or six times before replying.

Nonsense with dns what, others say that the LAN is not passable, if the network card and network cable are fine, check the interface of the switch, connect the computer with the problem to other interfaces to see if there is no problem, if it is normal, it means that there is a problem with the passing interface, the switch generally does not need to be set, if there is still a problem, check whether the IP address is correctly configured.

The speed of the network card, duplex mode and the peer device may not match, try to force the full duplex 100m to see, if it is a private line, some co-conversion ethernet ports are 10m full duplex.

According to your description not in detail. It is initially believed that your network card is in conflict with the computer in your network or the computer name conflict. Or a problem with the CIDR block setting. You check it out.

If you can know your network settings in detail. There may be other understandings.

"The network is not available from time to time, and then the network connection of the network card is disabled, and then the network is restored. ”

This sentence doesn't make sense, huh? I don't really understand.

But you can try it and ping the gateway first. Take a look at the extranet under ping.

In the case of dual network cards, the external network is shared with the intranet by setting up soft routing.

Materials required: computer, cmd.

Second, after a certain number of times the keyboard press "CTRL+C key" to view the results, the packet loss rate does not exceed 10%, and the average response speed does not exceed 100 milliseconds, which are normal speeds, if the data here is not normal, you need to find a telecommunications company to repair the broadband line (Note: in the test, only the local computer is connected to the broadband to avoid inaccurate testing).

5. Then click "Limit Upload Speed" of the device to give a certain speed limit, so after the speed limit of the device is completed, there will be no more intermittent situations when using the network again.

Click Start in the bottom left corner and click Run.

Typing ping -t is generally the data that is reversed is reply from : bytes=32 time<1ms ttl=128

This indicates that the NIC is installed correctly.

Enter ping -t or 192...T (gateway) generally reverses data as time<1ms ttl=128

This indicates that the connection between the computer and the network device such as the router is normal, and if the time out occurs, the connection between the two is faulty.

Enter ping -t (**) to generally return the data time<21ms ttl=128, etc., indicating that the network is normal, if the time out occurs frequently or the time value is large, the network has a problem.

Ping ipconfig first to show your own IP address, and then ping your own IP address, 0 loss is ping.

Start-run-cmd-

First, ping

Ping your IP again

Ping the default gateway again.

Ping the remote host and DNS server.

There are many ways to test whether the network is connected, as shown below:

1. LAN test method: If you are testing whether the network equipment in the LAN is connected, you need to know the IP address or computer name of the other party. If you know the name or IP of your computer, open the Start Menu - Run Enter cmd.

After entering cmd, run the ping command to check whether the device is connected. In cmd, enter: ping IP computer name -t

Use the ping command to test if you can surf the Internet: open the Start Menu - Run, and enter cmd in Runtime. Enter cmd and type: ping -t or ping some commonly used DNS address.

Ping ipconfig first to show your own IP address, and then ping your own IP address, 0 loss is ping.

You first check your local Netcom IP on the Internet, and then ping, but now you say this, I can't give you a certainty, and ping your own IP will definitely not work.
