My network will drop 10, my network will go down

One is that your network is unstable, there are many factors, such as switch hardware, network routing, etc., and the most critical disk is to see if there is an ARP virus, resulting in IP change, so that the exam results are likely to be lost, because the accounting software will be interrupted once the service connection is lost.

You're going to be like this if the switch is aging. And you have a clean intranet there.

Otherwise, you need to use the immune gateway to do a good job of intranet security. If there is a machine on the intranet that sends a large number of broadcast packets, ARP packets, you can use that kind of software, which must be very influential.

I don't know if you're screencasting there or not, if it's the same when you do other operations, such as using a simple open**ah or something. Is this also the case with the machines below? If this is the case for such a small operation, it means that there is an intranet problem.

If it's a small one that's very smooth, it's a different Spider handle. There are a lot of people who use it. There's also the problem of someone copying on the intranet and transferring files will also affect you there.

It turns out that our company's network situation is the same as yours, and the network speed is also very stuck when the connection is not dropped. I did the following checkup:

1. Check whether the network equipment and network cable are damaged, and eliminate the hardware equipment failure.

2. Check whether there are often a large number of people on the intranet or use attack software such as P2P terminators. Through observation and visits, it was found that it was not caused by this reason, the company's colleagues knew very little about computer technology, and the company had clear regulations that it was not allowed to look at **and** things during working hours.

3. Check whether there are network viruses and network attacks on the intranet. Sniffer packet capture is used to analyze network traffic and find that the intranet is flooded with a large amount of abnormal data, and there are ARP attacks and DDoS attacks. At this point, it can be determined that the network problem is caused by an intranet attack.

Later, it was solved using an immune security gateway. In the monitoring interface of the immune wall, I saw that many network attacks were blocked, and now the network is very stable, and there has been no disconnection. The landlord can try it.

It can be said that ARP spoofing will have this situation, but it has nothing to do with the IP address, but it has to do with the MAC address, that is, the network card address, you can encyclopedia ARP spoofing, the content is very detailed, and there are solutions.

Of course, this will also be the case when the network load is severe, which requires the server to be well configured, and you can try to connect only a few to see if it will drop.

If the network is unblocked, have you observed the CPU and memory usage of the teacher's machine, and besides, try a different set of screen broadcasting programs!

1. Eliminate the problem of network cable or the problem of contact between the crystal head and the connection.

2. It may be a problem of voltage that causes the broadband cat to be heavy and cause the connection to drop, find a multimeter to test the voltage to see if it is normal.

3. Excluding the above two reasons, it may be caused by the incompatibility of the speed configuration of the computer network card and the Ethernet port of the up-connected device, you can try to change it as follows:

Right-click Neighbor on the Net Attribute Right-click Local Connection Attribute General Configuration Advanced Connection Speed and Duplex Mode, change the original "Adaptive" to "10M Full Duplex", and the problem can be solved.

Here's how:

1. First of all, we should check whether there is a problem with our network cable, first detect whether the connection between the network cable and the chassis is loose, and then see if the network cable is damaged, such as aging the network cable or being bitten by rats.

2. After making sure that there is no problem with the network cable, go back to the computer desktop and find the "Computer" icon, and then right-click and select the "Manage" option.

3. After opening the "Manage" window, we click on the "Device Manager" option from the list below.

4. After opening the option, then find the "Network Adapter" option and turn it on.

5. Select the network card we use from the drop-down table opened by the "Network Adapter" option, and finally right-click on the properties, click "Advanced" navigation in the pop-up interface, and select "Connection Speed and Duplex Mode" in the attribute list below, and then select "10Mbps Half-Duplex" in the "Value".

6. Restart the computer and turn it on to see if the network will be disconnected.

Your network environment says whether it's dial-up or if several computers share a router.
