Why is one of the two computers connected from the same switch slow?

Is it normal to take the switch ? Check if your cascade line is good.

There may be a problem with the network cable from the router to the switch.

If the ping route has the phenomenon of packet dropping, that is, you have a problem with the intranet, and you do not consider the switch, line, or crystal header. How can the problem be solved? Connect it with an external network cable alone, a computer, and then use an external network cable to connect the router and then connect to the switch, bring a computer, and test the reason.

This cabling will affect the response speed of the network, but it will not affect the belt of the network.

The network response speed of the computer on the last switch will be a little slower than the network impact of the computer on the first switch before it will be a little slower (not really).

Here's why: the switch has a processing chip that processes the data. Transmit data from n lines to receive on 1 line. In terms of the principle of the switch, in fact, this wiring will not affect any network speed and so on. It is equivalent to connecting to the first switch at the same time.

But! In actual use, the processing capacity of the switching processing chip is limited. When the data passes through the switch, it is actually consumed in milliseconds or 0A few milliseconds. It depends on the ability of the chip of your switch to process data.

Normally, if all computers are pinging to test the response speed of the DNS. The computer of the first switch is suppose it is 10 msThen the computer on the last switch is estimated to be around 20 60ms.

It depends on the processing power of the chip and the amount of network load).

Of course, if you play the game, you will be almost impaired. But the bandwidth is the same (that is, the maximum speed of the next thing), and as long as the network cable is not stretched too long, the interference is not too large. The drop rate is not too high.

At last. There is another disadvantage of this wiring method.

Traffic jam And if the computer on the last switch uses btSince the data goes through all the switches. This data is double-counted by all switches. Therefore, it will cause the network of all computers to freeze

However, due to the fact that the processing power of the router is also extremely limited. So even if all the switches are connected directly to the router. As long as you have one of the computers with BT

It can cause the entire network to lag (in fact. Switches process data as simple consolidation. The router also has a routing function.

So basically, the probability of router lag will be much higher than that of the switch. So it's not too much of a problem).

A little slow, it is recommended that you connect the 3, 4, and 5 switches directly to the router.

Will be slower Signal response delay 1: It is not recommended to wire this way Ideally the router is routed side-by-side on the 4 switches behind the street.

2: The speed of the Internet will definitely affect especially if you are using this method in the connection mode, according to your needs, it is recommended to use the side-by-side connection method.

It's going to be slower, but it's not going to have a big impact.

1. There are 108 kinds of intranet attacks!

It is possible that someone uses P2P terminator, network law enforcement officer, Jusheng network management and other software to limit the speed of others and do ARP deception.

Or maybe the intranet has a flood packet attack, and the spam packets clog the entire network, and a computer can send 80 megabytes of data per second, believe it or not?

The immunity wall is specifically for LAN security and management, and we can think of the immunity wall as such.

1. It is a set of intranet underlying firewall: it completely solves the network attack of viruses and Trojans, disconnection and stuck problems (especially for the processing of layers). Solving the problem of ARP (Innate Immunity, ARP Exploration) is unmatched.

2. It is a set of real identity access system: strict and effective management of the identity of the terminal computer in the network (real IP, MAC, CPU hard disk, motherboard, genetic). Completely solve IP spoofing (private cables, cloning, IP conflicts).

3. It is a set of network bandwidth management equipment: fine intranet bandwidth management, load balancing, and traffic statistics (intranet and intranet, server, application delivery).

4. It is a comprehensive network management software: observe the internal protocol process of the network, remote debugging management (monitoring center, audit).

4. It is a comprehensive network management software: observe the internal protocol process of the network, remote debugging management (monitoring center, audit).

In this case, it is very likely that there is an attack in the intranet, or the junk data in the intranet is blocking the port! It's better to upgrade the immune network.

。。。It is recommended that you change the network topology.

Drag one to the other.

Change to find a switch with a larger backplane bandwidth as the core layer switch, and use it specifically for routers connected to the external network or other Shemar devices, as well as several other switches, and don't connect PCs to them

The other switches are only connected to the PC and the switch at the core layer, so I guess it will improve the network somewhat.

I guess it's too many switches, I haven't tested 3 switches, I'm only 2 at most.

You can try connecting the third switch to the first switch with a longer cable.

How many layers of switches are there? Set a trunk port between the switches to see if the speed is limited.

First of all, you should be talking about a computer switch here that is used by a home Ethernet switch or other smaller network switches, which are generally fool-proof. So how do you use this kind of small Ethernet switch for home computers?

It's actually very simple, in a word: plug it in and you can use it. Just plug it in, plug it into the network cable and you're ready to go.

The following is a detailed description of its purpose and how to use it:

General Purpose of Switches:

If you want to get more computers online at home, and you don't have enough router or modem interfaces, you can use one or more switches. Connect the outdoor network cable to the router or modem (modem), dial on the router or modem (cat), then connect to the switch, and then connect to the computer, so that the computer on the other port of the switch can access the Internet.

How to use: Switch interface description.

a. Generally, the back of the switch is the slot of the network cable;

b. The side of the switch is usually the interface of the power cord, of course, the possible position of different switches is slightly different, but it is generally on the side.

c. The front of the switch, mainly the indicator light of the switch, etc., can be determined through the flashing of the corresponding indicator light of each interface here.

Switch settings.

a. Plug in the power supply: After the power cord of the switch is successfully connected, there will usually be an indicator light on the front of the switch.

b. Plug in the network cable

First connect the external broadband network cable to one of the interfaces of the switch, and then use the network cable to connect the switch and your computer.

To this Liang Ranli is basically successful. Nowadays, the use of switches is relatively simple, and the computer can be automatically connected to the LAN or the Internet after the connection is successful.
