网速慢的原因及解决办法（Reasons for slow speed and Solutions） ! (quote) Collect relevant reasons about slow speed and how to improve it! I hope we can help!! There are additions and changes, if there is a mistake, I hope the expert corrected. First, the network itself problems The server that you want to connect to is not full or too large. The solution is simple. Please change it at another time or change your target site. Two, network problems lead to slow network We know that twisted pairs are tightly twisted together by four pairs of wires in strict accordance with the rules to reduce crosstalk and background noise. At the same time, using only a pair of 1, 2 and 3, 6 and four lines, in the T568A standard and T568B standard in the 1, 2, 3, 6 for sending, receiving, and for 1, 2 must be from a pair of winding, 3 and 6 must be from a pair of winding. Only in this way can the crosstalk be avoided maximally and the data transmission is guaranteed. In practice, I find that there is a great deal of hidden danger in the network cable which is not produced according to the correct standard (T586A, T586B). The performance is: one situation is that the network speed is slow when it is first used; the other is to start the network at normal speed, but after a period of time, the network speed is slow. The latter situation is very obvious on a desktop computer, but the speed is normal when checked by a laptop computer. For this problem, I have many years of practice found that the network speed caused by the failure to produce the correct standards is related to the quality of the network card. General computer card performance as the notebook computer, therefore, in troubleshooting exchange method, using a notebook computer does not rule out the detection speed of normal cable does not make this problem according to the existence of standard. We are now required to press T586A, T586B standards to suppress the network, in the detection of failures can not all use notebook computers ins
