The network is disconnected, very annoying and irritable

Check whether the single machine is connected to the cat or whether the router is connected to multiple computers. If the stand-alone machine is connected to the external line, test the external line and the computer and the cat. If multiple computers are connected to the router to access the Internet, it is likely to be an intranet problem.

Like some networks often drop, stuck, slow and other problems, several factors are related to 1, the external network bandwidth is insufficient 2, some people use BT, Thunderbolt crazy**, the network speed of other machines is occupied 3, some people use P2P terminator, network law enforcement officer, polyworm and other software to limit the speed of others 4, some computers are hit by ARP virus (due to the process of opening web pages, ** virus) to attack other computers, resulting in disconnection 5, some network cables or crystal head poor contact problems and so on.

The probability of instability of a hardware router is very small short, the probability of network cable connection problems is also small, and the possibility of insufficient bandwidth is not large. 80% of intranet disconnections are caused by intranet attacks. A company with dozens of computers must be connected to the switch, many ARP attacks do not go through the router, directly through the switch to other computers, there are some attacks on the intranet that almost no hardware router can solve.

The patrol immune network solution solves the problem of intranet attacks from the network card with immune wall technology, and sends a "policeman" on each network card to record the MAC address (DNA of the network card) when the network card leaves the factory, and any intranet virus attack is directly "arrested" at the network card, only legitimate data packets are allowed to pass, and harmful data packets are directly intercepted at the network card. It also monitors the intranet without an IP, monitors the Internet access information of each PC, intercepts information, alarms information, and evaluates and blocks these problems. Solve the problem that the intranet is disconnected due to the connection of intranet ARP to other virus attacks directly from the network card, and the intranet is difficult to manage.

Problems with telecommunications rooms. I tried it too.

It is possible that there are too many people on the Internet, causing the network to crash, and you can report it to the network center of the school.

1. It is likely that there is a computer that uses Thunderbolt and BT** to seize bandwidth 2. It may be that his computer has software to limit the speed of your ARP attack 3. It may be that the computer's system is poisoned and the virus attack clogs your network. To solve these intranet attack problems, the current solution for you is the immune wall technology, and the immune network solution is deployed through the immune wall technology. Immunity network solution, you don't need to make major changes to your network, you can use the immune wall to set up a policy, do not install a driver, do not let the Internet, and intercept it when it is installed.

It can directly intercept the virus attack sent by each computer from the network card, carry out unified management, there is only one network administrator, and it can also monitor the Internet access status of the entire intranet computer, and accurately locate and alarm if there is an abnormality.

You're Wi-Fi and wired! The first thing to do is to see if your cat is off when the light is abnormal! If there is an anomaly, such as a flashing light! Explain that there is a problem with the line, you can find a maintenance person to maintain it@!

I've also encountered this problem, and I always asked you to check this, that, and finally let them come to check the results for a month, the network was broken, and he came! In the end, it was explained that it was caused by the overheating of their computer room! Speechless!

In your case (the connection is dropped at 9:50 p.m., and then you can get on it at about 10:20 p.m.), if several people share a network cable, someone may be using P2P! There is also an update of the network card driver! Hope it helps!
