Is the local connection status packet only sent but not received?

Your computer can only broadcast to the outside world, and there is no response, which means that you are not connected to the internet at all. Or your network cable doesn't have networking capability.

In this case, we should check one by one:

1. Is the cable connector connected correctly? There are two pairs of cables, 1, 2 is responsible for transmitting data, and 3 and 6 are responsible for receiving data. This can happen if the cable connector is not connected correctly. Just try to connect the cable to another computer.

2. If it is available on other computers, please check the network card again. Poor contact between the crystal head and the network card will also occur. Insert it several times, or unplug the network card and try another slot.

3. If not, see if the network settings, such as IP address and DNS, are set up.

If all these places are normal, then the motherboard or system may be broken.

Several reasons for poor network:

First, the network itself (insufficient server bandwidth or excessive load)

Second, the network cable problem caused the network speed to slow down (twisted pair is not up to standard, which is manifested as: one case is that the network speed is very slow when it is first used; Another situation is that the network speed is normal at first, and it slows down after a while)

Third, the existence of ring road in the network leads to poor network.

Fourth, the broadcast storm caused by the hardware failure of network equipment leads to poor network?

Five, a port in the network formed a bottleneck, leading to poor network.

6. Does the influence of worm virus lead to bad network?

Seven, excessive use of firewalls

Eight. Insufficient system resources

The network difference is mainly caused by the above reasons. Personally, I suggest you clean up the garbage process of the computer first and optimize the system. Trojan horses are also pests!

Solution:

First, please go to another time or change the target website.

Second, check whether the twisted pair is qualified.

Thirdly, the method of partition and segmentation is adopted to gradually eliminate loop faults.

4. Test the involved computers one by one with the "Ping" command under DOS. Network cards, hubs and switches are the most likely devices to fail and slow down the network.

5. Replace the server network card with 100M or 1000M, install multiple network cards and divide them into multiple VLAN, and change the router configuration to increase the bandwidth.

6. The anti-virus software used must be upgraded in time; Computers should also upgrade and install system patches in time, uninstall unnecessary services, and close unnecessary ports to improve the security and reliability of the system.

If you can solve these problems, your network will be stable and the network speed will be fast!
