The speed of the computer is only half that of the Internet 15

The megabyte in broadband speed is usually referred to as one million bits per second. bps (bits persecond), that is, bit rate, bit second, bit second, number of bits per second, and the common unit of data transmission rate.

And the megabyte of file size is usually 8mbyte. A byte is a unit of measurement used by computer information technology to measure storage capacity, and also represents data types and language characters in some computer programming languages.

The conversion relationship between bytes and bits is as follows:

1byte＝8bit

1kbyte=1024byte

1m=1024kbyte

The exact situation is not clear, but there are several ways to show the problem:

2. The router is receiving wifi, you can enter the background settings, that is, the advanced wireless settings, and remove the one with the "wmm" word option, which is useless and is to limit the speed. (And if you say it's the same if you don't connect the router, then this can only be used as an auxiliary).

There are a few common reasons why your broadband network is slow:

1. If the bandwidth of the ** server is narrow or the server is busy, you can try to change the time period to access or access other** to determine whether this problem is caused;

2. Computer reasons such as low computer configuration or weak system processing power;

4. The use of routers to share the Internet leads to slow network speed;

5. If the modem device is unstable, it is recommended that you replace the modem device for testing;

6. Line reasons (such as long line, noisy line, poor quality of the entrance line, change of the user-side line, etc.).

Under the same wifi, the computer network speed is only half of the actual one, but the mobile phone is normal, why is this?

Internet Geeks", a new perspective and new ideas, accompany you to travel in the magical world of science and technology.

Thank you for the Q&A invitation.

Test under the same wireless wifi to ensure that the wireless access power is different under the premise of different devices.

First of all, it is not due to the insufficient bandwidth of the router, the iphone7 test is 100 megabit bandwidth;

Secondly, in addition to bandwidth, the transmission speed of wireless wifi is also limited by the wireless protocol.

Netizen answer: The main question is: Some of the equipment under the wireless network meet the network speed standard, and some do not meet the standard, why?

If you want to meet the network speed standard, there are many restrictions, and all factors in the network must be commensurate with it, from the phenomenon described by the subject, the network to the wireless router is up to standard, but the network speed of each terminal is different, and it can be judged that the problem lies in the terminal equipment. The main reasons are as follows:

First, the terminal does not support the 5GHz frequency band.

The frequency band, the fastest 11n protocol, generally works at a speed of 150Mbps, and because of the transceiver mechanism, the connection speed is often 150Mbps 2 75Mbps. Coupled with the various reasons for wireless signal interference and speed reduction, the measured network speed is only 50Mbps, which is also normal. Generally, older devices, such as notebooks, do not support 5GHz, and now new devices basically do not have this problem.

Second, the performance of the terminal wireless network adapter is limited.

The wireless network adapter is what we often call the wireless network card, due to the hardware manufacturer or manufacturer, in order to save costs, according to the network at that time to adapt the network speed. In the early years, the broadband bandwidth was about 10 20M, and the manufacturer did not need to require the adapter to have such a high network speed, and the processing performance was about 50M, which was fully capable of meeting the needs at that time, which would cause the network bandwidth to be increased and the network speed of the terminal equipment could not be improved.

The third is poor terminal performance.

At present, network adapters need the CPU of the terminal device to do various computing and processing such as various computing protocol conversions, and use memory for caching. For example, if the performance of the mobile phone is poor, or if the mobile phone resides in the background of a large number of background programs, occupies a large amount of memory, and consumes a lot of CPU computing power, it will seriously affect the processing power of the network adapter, and then make the network speed unable to improve.

What should I do if the internet speed at home is too slow? Teach you a trick, you don't need to spend money to change to a new one, and the network speed can easily become fast.

The network speed has nothing to do with the computer, of course, the dual-core is compared with Ben 2, it has a relationship. Internet speed problems, it is recommended that you take a look at your cat's connection and **speed test,If you think the hardware is okay, call**10000。

Uninstall all the antivirus software, and leave Microsoft with the one.

For brother, you use 360 to clean up the system junk, and turn it on again after shutting down.

There are too many temporary files on my computer.

There are a few reasons for a slow internet connection:

First, the network itself problems (insufficient server bandwidth or excessive load) Second, network cable problems lead to slow network speed (twisted pair carelessly and meet the specifications, which is manifested as: one situation is that Li Lu's network speed is very slow when he first uses it.

The other situation is that the network speed is normal at first, but after a period of time, the network speed slows down) Third, there is a loop in the network that causes the network speed to slow down.

Fourth, the network speed slows down due to the broadcast storm caused by the hardware failure of the network equipment.

5. A bottleneck is formed on a port in the network, resulting in slow network speed.

6. The influence of worms causes the network speed to slow down.

Seventh, prevent the excessive use of the fire wall.

8. Insufficient system resources.

Try to choose a time when there are fewer people, for example, many people are on the same road, and it is also very crowded.

Other situations. 1. There are viruses or Trojan horses

If the network speed is very slow, it is a network problem, if there are too many programs running, it is recommended that you use 360 security guard to check it all, optimize the boot start item, and turn off the boot that you don't want! Clean up the next vicious plugins and system junk! Reboot it out! It's going to be a lot faster!

Sometimes the computer itself is slow and needs to be optimized. Sometimes the transmission speed is slow, such as 2G is not as fast as 4G; Sometimes there is a temporary problem with the broadband room.

Check to see if your Group Policy is restricted. It may also be that there are other software that is taking up traffic at the same time.

Then this has something to do with your computer. You change the network card. Give it a try.

Update the network card driver, the next driver wizard.

There is a problem with the computer's wireless receiving module or the router signal transmission is not good.

You can clean up files, speed up the network, and most importantly, clean up the C drive.

Simple, your computer is running too many processes, and it is very likely that it has already fallen into the junk plugin.
