I don t know why the network is so slow

Broadband disconnection and slow network speed are caused by three reasons: 1. Responsibilities of operators (transmission and switching network failures).

Operators must ensure that the signal quality to the user (bandwidth, bit error rate, signal-to-noise ratio, transmission rate, signal level, input and output impedance, signal stability, input and output impedance stability) in line with national standards); Specific**: Telecom 10000 Netcom 10060 Tietong 10050 Second: User (responsibility) The following factors will lead to your current state, if there is no problem with the above-mentioned operators after detection, the next is your user's own problem; If you don't have the following problems, you can directly call the operator** and ask the operator to deal with the operator's own related matters.

The other ** is very good, and a certain ** is particularly bad, which is the problem of ** itself, and has nothing to do with the operator and the user.

The reasons for slow network speed are: device problems, cache usage, hardware problems, and network cable problems.

1. Equipment problems

In fact, the router needs to be turned off, when using electrical appliances, there is often the phenomenon of aging of electrical appliances, and the router is also a late rise without electrical appliances, there will also be aging phenomenon, if the router is not turned off for a long time, for some small parts inside, it will cause great damage, resulting in various faults of the router, especially in summer, when the weather is hot, the degree of damage is greater, resulting in slower network speed.

2. Occupy cache

The working principle of the router is to accept the signal and then output the signal, so it needs a large memory to cache these signals, if the router is not turned off for a long time, it will make the router accept the signal laughing limb and the output signal is not smooth, which will affect the network speed.

3. Hardware problems

Poor computer hardware will also cause the illusion of slow network speed, for example, the network card is 100M, but its own broadband is 200M, the network cable is more than six categories, the router is Gigabit dual-code nanofrequency, but the speed is still slow, the network speed bottleneck lies in the computer network card.

4. Network cable problems

When the broadband speed is increased to more than 100m, the speed is still at the speed of 100m, and the gigabit router cannot be improved, it is necessary to consider the problem of network cables, most of the network cables sold by the commissary are 5 types of lines, not even more than 5 categories, the maximum transmission speed can only provide 100m, at this time, even if the broadband speed is increased to 500m, then affected by the network cable, the actual **speed will not exceed 13m per second.
