Is the sudden slowdown of the network a problem with the switch?

Reason 1: The fault of local viruses and Trojans.

This is the answer that many netizens think of for the first time. Yes, infection with certain viruses and Trojans can indeed cause slow internet speeds. However, how many netizens will verify it?

Verification Step 1: Use anti-virus software to check for viruses thoroughly. This is the easiest way to do this, but it doesn't always work out.

Verification Step 2: Observe the CPU operation and network conditions. If the CPU is running non-stop for no reason, and the network connection is constant, it is possible that a virus Trojan is the cause.

Verify Step 3: Dos commands. Ping under DOS to see how responsive the network is.

Cause 2: Server issues.

Surfing the Internet has to go through many servers to reach your destination. Therefore, the server directly affects the user's network speed. Network congestion can also slow down internet speeds.

Cause 3: Network viruses targeting the server.

Network viruses that target servers tend to slow down or bring down networks. However, it is not the user's business to solve this problem.

Cause 4: Local system issues.

The system takes a long time and often fails. If the internet speed slows down suddenly long after the device is turned on, you may want to restart it to see if it solves the problem. Sometimes, it is even necessary to reinstall the system to solve the problem.

Reason 5: The CPU is busy working.

The CPU is busy working and will directly affect the network and computer speed. So it's necessary to check how your CPU is working when the internet is slow.

Is there a worm in the LAN? It's also possible that the switch is broken, try another one.

The problem of the network cable, the crystal head of the network cable has been redone, and the side line is tested to it

No, it won't. Because the switch is equivalent to the original hub (hub), let it have exclusive bandwidth for each port, if the switch is a 100 Gigabit switch.

It means that each port on your switch is the same rate of 100 megabits, and the switch plays the role of ** data packet in a local area network, and the router is a device across the network segment, which is equivalent to a gateway.

Summary. Dear, I'm glad to answer for you, after using the switch, if the network speed slows down, it is caused by the following reasons:1

Switch bandwidth issues, if you are using a low-bandwidth switch, it can become a bottleneck and slow down the network speed. High-bandwidth switches need to be replaced to increase network speeds. 2.

If you use a switch that can implement load balancing, but improper configuration or improper use will cause the network speed to slow down. You need to check the load balancing parameter settings and make adjustments. 3.

If the unreasonable structure design will affect the efficiency, latency, and transmission rate of the switch, the network topology should be adjusted and improved according to different scenarios. 4.Network environment problems, if the network environment is relatively bad, the transmission of equipment will be affected, interference, noise.

Ensure that the environment where the switch is located is appropriate to avoid interference to the switch. 5.If the parameters of the switch are not properly configured, the network speed will slow down.

You need to check and optimize the configuration of the switch. STP, MAC binding, VLAN configuration. 6.

Network equipment issues, which can lead to network congestion if the user device is not configured for local use. Network devices need to be configured to avoid congestion. <>

In addition, if you are sure that there is no problem with the xingxing energy and configuration of the switch, but there is still a problem of slow network speed, it is recommended to replace new network equipment or upgrade network hardware to improve network bandwidth and efficiency. <>

Your switch address is specified as, your IP is automatically obtained, and then try, otherwise which device do you turn on?

The best way to detect is to connect the dragged cable to your computer first, then check if there is any problem with the router settings, then connect your computer to the switch first, first set the IP address of the switch and clone the MAC address, then check the settings, and finally plug the dragged network cable into the switch and try.

Is the switch 100 Gigabit? Also, if your neighbor is modem Internet or fiber, whether the switch settings have set restrictions, etc., if the other party is using modem, you should set the switch to a secondary switch when you connect it, so that there will be no conflict.

0 hard work.

1. Check the network cable connecting the switch and the computer, and press the network cable according to the international standard line sequence (take it to the computer city and use the straight-through network cable standard).

2. Check whether these two computers are virus-proof. It is recommended to install antivirus software, Kaspersky (free trial for one month) is recommended

3. It may be a problem with the switch, try another one (since only 2 computers are added, it is recommended to use a 5-port small switch, about 50 yuan).

After connecting to the switch, the network speed is very slow, you can disconnect the switch, so that the network speed is relatively fast, probably because the local network is poor, so it will be like this.

Hello, in this case, first of all, it is possible that the network speed you are using is not high, and secondly, it may be that there is a certain problem with your switch.

After connecting the switch, the network speed is slow, you can turn off the switch and restart it to check it.

If this happens, it's a good idea to check if your internet speed is slow.

If the route bai

There are many outs. It doesn't matter if you use the integrated DAO switch of the extra zhi router, it is best to turn off the DHCP function of the router within it, otherwise some machines without IP may use the DHCP function of this router to obtain IP after booting, so that the gateway of the computer will automatically point to this router, so that the computer will not be able to access the network. You also need to change the IP of this router, if it is the default, it may conflict with the existing router, which will cause the Internet to be extremely unstable.

Two points: 1. Change the IP of DI-504, the default is or, if the existing router uses the default, change the DI-504, such as or.

2. Turn off the DHCP function of DI-504.

Adding network devices won't make the network lag, and if I don't do the two things I said, there may be problems with the network.

Of course, it is the first type, and it is better to connect to the router when four BAI switches are connected to the same DU than zhi. But beware of router DAOs

The distance between the switch and the switch is dedicated.

The shorter the better, preferably not more than 70 meters, because the maximum transmission distance of twisted pair is 100 meters.

The second method is called cascade, which will generate a data storm within the network, affecting the stability of the entire network.

There is no way to solve it, in addition to increasing the bandwidth, if the switch is fine, that is, there are more computers connected after adding the switch, and the network speed will naturally be slow, unless the speed is limited, otherwise the network speed will definitely not be available.

It may be a problem with the wireless router, because it's summer, and many routers will have the problem of performance degradation after heating, try a new one, it should be good.

Each port of the switch is independent, it is a 10m network, so the network speed of the computer connected by the switch is very fast, and the router connected by the switch is also a 10m network, but its 10m network speed is distributed to everyone in your unit who uses the wireless network, and there are more people who use it, and the network speed shared by everyone is less.
