COMPUTER NETWORK PROBLEMS AND SEVERE PING PACKET LOSS

There is another possibility, that is, there is an ARP virus on a certain station, which will also cause packet loss!

In the next ARP firewall, you can see which machine keeps sending packets, and then let that machine kill the poison!

The ping of the computer game is very high, and the serious packet drop can be solved by installing the game accelerator on the computer, and the specific operation steps are as follows:

1. First of all, open the installer of the game accelerator on your computer

<>3. After completing the installation, click the Finish button

4. After that, the accelerator will start automatically, register one, and click OK:

5. Finally, start the game, so that there will be no problem of high latency when playing the game:

Summary. 2. After ping the DNS, please check the ARP -A table to see if the corresponding gateway is correct, if not, it is determined that there is an intranet attack and ARP spoofing. Right.

What should I do if the company network pings the telecom DNS packet loss?

Hello, for packet loss, you can solve it in the following ways: 1. Please check whether the bandwidth allocation is reasonable and sufficient! There was no such situation before when there was not such a large number of machines, but as the number of machines increased, the demand for applications would also increase.

2. After ping the DNS, please check the ARP -A table to see if the corresponding gateway is correct, if not, it is determined that there is an intranet attack and ARP spoofing. Right.

3. Network problems, network solutions. For intranet attacks, they should be suppressed from the source and guarded from the gateway. That's how it can really be solved.

In order to ensure the security and stability of the intranet, the patrol immune network solution uses terminal driver + system monitoring + intranet security protocol + gateway inspection.

On the left, ping telecom dns behind the core switch also loses packets, and fiber optic directly plugged into the laptop does not lose packets.

Hold on. 1. Take the switch and the finished switch network cable out of the switch and take it to another place to access the network separately to see if the computer can access the Internet normally.

2. If there is no problem in the front, continue to check up, do a good job of incoming network cables, re-press once and use a line tester to measure through, first directly if the host does not lose packets, connect to the switch to see if the problem is solved. If you still lose packets, see below.

3. Directly from the new root into the network cable bar, see here you will think that there is no need for it, the line is good, you can connect to the computer alone, then I tell you, the network cable must be changed, 80% of the root will be good, as for why I can't say why, it will be good to change the root.

Suggestion: (1) Don't be greedy for cheap network cables, buy good ones, (2) It is best to connect the crystal head to the ceiling before wiring, (3) If you don't worry, you can use a switch to test it well.

Isn't the bandwidth too small here.

It must be that the larger the bandwidth, the better<> as long as it is enough according to the actual needs.

Ok afternoon I'll try again. Good.

Change a network cable to test, otherwise add a network card to try, you can also change the router or the port on the switch to try, the switch reboots, or get a direct connection to another computer to test, generally is the network cable, network card, switch or a single port of the problem, the system problem may also be the cause of the driver, anyway, these have to be compared and analyzed.

It is recommended that you restart the router, and the problem can be basically solved.

Happy New Year!

If you can ping, but the packet loss is serious, it is recommended to try a new crystal head

1. If it is a software problem (such as a firewall or setting problem), it should be completely unpingable instead of packet loss, and the same problem should occur on the desktop at home;

2. If there is a problem with the network cable or router, your laptop should also have the same problem.

So what's the problem? There are only possible interfaces for network cards and network cables. Maybe some of your network cable crystal head has been oxidized, and your desktop network card interface has also been oxidized, and there is only one device interface with a large impedance, which may not have an impact on the Internet speed (so your desktop is connected to your neighbor's network, or your laptop is connected to your home's network, no problem).

However, if the impedance of both device interfaces is relatively large, the network speed may be slow or unstable.

To solve this problem, you can change the crystal head of a network cable or change a network card. But in terms of cost, the cost of changing the crystal head is the lowest, so you might as well try it first.

The above is my speculation, I hope it can be helpful to you.

The line is good, but unstable. It is highly recommended to try a different network cable, and the crystal head oxidation on the first floor makes sense.

The problem is very clear, there is a problem with the desktop, first reinstall the system, if not, you can basically determine that the network card is broken.

Obviously, there is a network virus on the intranet. It is recommended that your company learn about the Patrol Immune Network solution. Upgrade your network from a normal network to an immunity network by deploying a patrol immune network solution.

On the surface, these network problems are caused by network viruses, but at a deeper level, they are caused by the inherent defects of Ethernet and the difficulty of management.

Method: 1. First, use the keyboard to type Windows + R keys to open the "Run" window.

2. Enter the "cmd" command in the "Run" window.

3. After entering the command, click the "OK" button.

4. After clicking the "Confirm" button, you can enter the command prompt window (i.e., the cmd window).

5. After entering the command prompt window (i.e. cmd window), enter the command where the cursor flashes"ping"and enter a space.

6. After the space, enter the **** that needs to be detected for packet loss rate, and enter the format of ** as, "www.".**com" or"www.

*.cn", where "** represents a specific ** name. Take the homepage of the 360 official website as an example, then enter""。

7. Enter ** and click the Enter key (i.e., Enter key) to view the network packet loss rate.
