Ask a question about network disconnection and what problems will cause network disconnection

If the firewall does not have attack logs, it means that it is not an external network attack.

LZ can vigorously troubleshoot the problem of the intranet, two-way binding can solve the earlier ARP virus, the current variant is not defensible, there may be other attacks on the intranet, such as the attack of the skull, the flood of UDP, etc.

It is highly recommended to use LZ.

Hehe... This is also the case in your company!

Our company used to use the pix firewall network to do two-way binding, and the network disconnection problem still appears! At the beginning, it worked when I did two-way binding, but after a while, it still didn't work, and the disconnection still existed.

Later, we looked up a device on the Internet that was said to be good (to be precise, it should be a set of intranet security solutions), called Xinxiang Immune Wall Router, they came to our company to help us install and debug, the effect was obvious, and now it has been almost a year, and there has been no droppage, and the speed is faster than before.

Through consulting them, they learned that since 07, a new ARP mutant virus has appeared, and ARP two-way binding is ineffective against this virus, so even if two-way binding is done, it is futile.

Their router has ARP innate immunity function, and it is very convenient to manage the intranet after turning on the "immune wall mode".

The switch can also cause network instability if it is used for a long time.

1.Voltage issues.

When there was a problem with the circuit in my house, it often dropped like this.

Problems with movie plugins.

3.**There is a problem with the line.

My family also had this problem, and then I called someone from the telecom to change a large section of ** line, and it was fine.

Replug the cable to go online? Do you want to wipe it?

There are 2 possibilities:

1. Your network card is loose, the crystal head is oxidized, and the solution to the collapse: reinsert the network card and redo the crystal head.

2. Your cat is broken, this is very likely, you replug the network cable is to reconnect the cat to your network card and successfully, change to a withered cat to observe. No shirts.

You've found a solution, it seems to be the problem of the interface.

It may be that there is a problem with the router, find a professional to help you take a look, the network cable is unplugged and unplugged, and it is easy to damage the crystal plug.
