My home has 1m of Internet access, why does the network speed test show that the access speed is 512

The theoretical speed is 1m 1024kbps and 128kbytes s can actually meet the following standards, which is quite good.

If you can't reach it yet.

1. You have been fooled by the operator.

2, I was indeed fooled!

3, no way, I was fooled!

A lot of Internet speed tests on the Internet are messed up, and each one is different

Measure it several times, theoretically it is 1m, but in practice it is impossible to reach 1m, different time periods, different network speeds, it is recommended to test again at 2 o'clock in the middle of the night.

Do you use telecommunications, or do you use Netcom? Either you have a problem with your computer, or it doesn't have 1m with your own

1M broadband: The speed is 65KB or more.

2M broadband: 135KB or more 3M broadband: 256KB or more.

4M broadband: the speed is 384KB or more 10M broadband: the speed is 500KB or more.

Data is worn out during transmission, so a part of the traffic will be scrapped to keep the data intact! So the network speed is pulled to 1m, and the actual speed is not that much!

1: What kind of speedometer are you using?

Install a 100m broadband at home, and the staff said that it was 100m when handling and installing, but after their own speed measurement, they found that it was only about 10m, a difference of nearly ten times, why? After looking for the staff theory, I finally understood that there was no fraud on the part of the operator, which was really misunderstood.

Your network card should be 100 Gigabit network card and it is not supported. You need to configure a NIC larger than 500M.

Doesn't the speed say 433, it should be 500.

Kbps is a 4M broadband speed.

3. The network speed is the speed of data transmission referred to by 512kbps, and bps represents the number of bytes (bits) that can be transmitted per second. 512kbps means that 512kb of data can be transmitted per second. Theoretically, this is the case, but in practice there will be a lot of differences, saying that the network speed is 512kbps, but in fact it cannot be reached.

5. Internet speed generally refers to the length of time it takes to request and return data when the computer or mobile phone is connected to the Internet, when uploading and returning data. To improve the (computer) network speed, it depends on the access network of the ISP (network service provider), which is generally divided into three types, ADSL access, FTTB-LAN access, and FTTH access, generally without changing the network access mode, increasing the network bandwidth, and will not directly improve the network speed, in other words, in the case of the same 4 trillion network bandwidth, ADSL access network speed is less than FTTB-LAN access less than or equal to FTTH access. The network speed mentioned in the telecommunication service is 1m, 2m, 3m, 4m, etc., which is calculated in the unit of data communication.

512kbps means that 512kb of data can be transmitted per second, and the network speed is the speed of 512kb of data per second. bps is the abbreviation of bits per second, which means "bits per second" in Chinese, indicating the number of bytes that can be transmitted per second.

There are generally three types of network speed, namely ADSL access, FTTB-LAN access and FTTH access, which cannot be directly improved without changing the network access mode.

The formula between m and kb: 1m = 1024kb

The formula for calculating the downlink speed of 4M bandwidth is: 4M 8=

The formula for calculating the uplink speed of 4m bandwidth is: 4m 8 10=

The downlink speed of a 400M bandwidth is calculated as follows: 400M 8=50Ms = 51200KBS

The formula for calculating the uplink speed of a 400m bandwidth is: 400m 8 10=

One trillion is equal to 128 kb, and you're about 4 trillion or so. However, if you use Thunderbolt speed measurement, you have to think carefully, Thunderbolt's speed is sometimes inaccurate, and the speed of two trillion it sometimes shows you 500-600kb

According to your data is megabytes. The theoretical network speed of 1 megabyte broadband is 128 kbps (note lowercase), and 1 megabyte broadband = 1024 kbps.

The exact point should be the megabyte of internet speed

If it's 500kb s, it should be 512k, that is, at most, 1m. Internet speed is unstable and will fluctuate up and down the nominal Internet speed;

If you make a clerical error and want to say 500kb s (b is uppercase), the speed is about 4m, the reason is very simple, 500*8=4000kb s.

The formula between m and kb: 1m = 1024kb

The formula for calculating the downlink velocity of 4m bandwidth is: 4m 8=4m bandwidth uplink velocity: 4m 8 10=400m bandwidth downlink velocity: 400m 8=50m s=51200kb s

The formula for calculating the uplink speed of a 400m bandwidth is: 400m 8 10=

Normal.

Why do broadband operators limit the upstream bandwidth of users?

In fact, in the final analysis, it is the restrictions imposed by broadband operators. The main reason why broadband operators limit the uplink broadband of home users is to save money.

As a result of netizens' long-term network usage habits, the uplink bandwidth usage is less than the downlink bandwidth, and if broadband operators give the same speed to the uplink and downlink, it will cause a waste of resources. On the other hand, selling uplink bandwidth resources to enterprise leased customers in the data center will provide more benefits. The server hosted in the computer room needs a lot of uplink bandwidth, and does not need too much downlink bandwidth, and the bandwidth is very expensive, often the cost of renting the 10m uplink line in the computer room is twice the cost of the family 100m, therefore, the downlink bandwidth to the home user, the uplink bandwidth to the enterprise user in the computer room, it has become a means for broadband operators to make profits.

Therefore, if broadband operators do not restrict home uplink broadband, one of the main reasons is that they are afraid that users will build *** in home fiber optics and affect their enterprise private line leasing services, and many enterprises may use home fiber to build *** instead of going to the computer room to host the host, resulting in the loss of interests of broadband operators. Therefore, broadband operators will not only not increase the uplink broadband of their homes, but will also prohibit home fiber users from building them privately by means of dynamic IP and limiting 80 ports.
