Usually when we surf the Internet, we will encounter slow speed, but the cause of slow speed is many, need careful examination to determine the cause and solution, the more familiar to the computer more easily learn to solve the problem, if the computer has some problems to be solved, it is very boring. such as the computer network slow such problems will often be encountered, then we will explain the details of the slow speed of the solution.

, documentation. In the above links must establish a sound document, as part of the acceptance.(Excerpt from: David's wiring bulletin board)Common mistakes in line playingThe common error of the line is open, short circuit, reverse connection (two of a pair of lines crossed, such as 1 corresponding 2,2 corresponding 1). Another error is bridging, such as 1, 2 corresponds to 3, 6. The main causes of this error are two. One end of the cable uses the T568A standard, while the other end of the cable

Computer network failure is unavoidable. Network fault diagnosis is an important work of network management. Generally when the network occurs information is not available, can not browse the Web, and other connectivity failures, the phenomenon is relatively clear, easy to observe and locate the fault point, such a fault is not difficult to solve. But the most troubling thing is that the internet is a pass, but the network speed slows down.When faced with this kind of "soft" fault for the first

Fault analysis of local area network speed slow de In many network failures, the most vexing is that the network is pass, but the speed is slow. The first face of this kind of "soft" failure, often some people will be helpless, this article for you to cause such "soft" fault common causes and elimination methods, improve the ability to deal with practical problems. 1, network cable problem We know that twisted pair is made by 4 pairs of lines strictly and reasonably tightly twisted together t

need to transfer data through a hub or vswitch. However, when connecting two NICs, you cannot directly use the express Connect line, but you must use the cross-type network line. When creating a cross-type network line, you must use the T568A line sequence to connect one end to the other, the other end uses the T568B line sequence connection. If the crossover network cable is not created in accordance with such standards, even if the two computers ca

For the first two kinds of errors, the general test equipment can be easily found, the test technology is also very simple, but it is difficult to find the string around. The error occ

; mFirst, make sure that the network environment of A and B has been set up, that is, the ADSL line is connected to the ADSL cat, the cat is connected to the router, the router is connected to the switch, and the switch is connected to each terminal. Make sure that the local networks of A and B are shared successfully and can access the Internet. (It should be noted that it is better not to directly connect to the terminal on the vro. It is not stable after it is connected. In fact, I will conne

two types: shielded and unshielded. If it is used outdoors, The Screen Shield is better. Generally, it is enough to use non-shielded five-category cables in the room. Because no Screen Shield is provided, the cables are relatively soft, but their connection methods are the same. In general, there are four pairs of lines twisted together in the cat5e category and marked with different colors.

The XG system shielding SL module launched by Tyco electronic AMP uses 360. The module adopts a metal shielding shell for overall shielding. It is easy to install and can effectively ensure the good connection between the cable shielding layer and the module shielding layer. The slim shape is compatible with the SL s

A. The status indicator of the NETCORE router lan interface corresponding to the physical connection error is abnormal) Solution: 1) check whether the network cable is strictly compliant with the

Faults in computer networks are inevitable. Network fault diagnosis is an important task in network management. Generally, when the network encounters a connectivity fault such as information failure and cannot browse the Web, the fault phenomenon is clear and easy to observe and locate the fault point. It is not difficult to solve such a fault. However, the biggest headache is that the network is accessible, but the network speed slows down. When faced with such "soft" faults for the first time

The network cable is already inseparable from our life. Because we often use the network cable, we need the network cable to access the Internet. Therefore, we need to learn how to make the network cable so that we can better control our life in Russia, Okay. Let's just talk about the network connection methods. This is the network connection method of two national standards. Generally, we use the second It may be difficult to remember this. I will teach you a simple method. Let's talk abo

twisted-pair and six-type twisted-pair line. Maximum bandwidth of up to 1000Mbps. Twisted pair of the only drawback is that the transmission distance is shorter, can only reach 100 meters, so in the wiring, if the use of star topology structure, covering the range can only reach 200*200 meters. 1000M network card data transmission is two-way, need to use four pairs of lines, that is 8 core wire. 100M below, generally use 1, 2, 3, 6, four root line.
