ADSL access network troubleshooting guide

The development of ADSL Access networks is very rapid, and there are also many problems, especially in the aspect of ADSL speed measurement, acceleration, and detection, which are prone to some faults, here we will explain the solutions to these problems and hope to help you. The ADSL Access Network is a high-speed broadband Internet access method that runs on the original telephone line. It has the advantages of saving investment, fast Internet access, and simple installation. At present, many local networks, especially Internet cafes, use this method. So can the speed of Internet access reach the speed defined by the ISP service provider? How can we further improve the Internet access speed? How can I determine whether the ADSL Access Network works properly? How can I find and solve an online fault? Let's talk about these issues.

I. How wide is the bandwidth"

For example, if a broadband access service provider promises 1 MB of bandwidth, can it reach 1 MB? To verify its authenticity, you must test it. However, there are many factors that affect the test results. For ADSL access network users, it mainly includes the aging degree of telephone lines, the distance between users to the telecom data center, computer configuration, the performance of the server connected to the website, and the number of people accessing the server at the same time. For users connected through LAN, it mainly includes Nic configuration, number of connected users, server transit efficiency, and server performance of the connected website. To ensure the objectivity of the test results, it is best to choose different time periods for multiple tests to obtain an average number.

1. Use IE to download files and test the network speed
The simplest test method is to connect to the FTP download service provided by the ISP. Use IE to download larger files and view the download speed. For example, if I use a browser to connect to the ISP's FTP to download files, the speed is about 70 KB per second, which is equivalent to a transmission bandwidth of about kbps, which is half the size difference between 1 Mbit/s and 1 Mbit/s. However, this result is not necessarily accurate. The method for downloading files with IE is simple, but the test results are not very accurate. If you want to learn more about your network conditions, you 'd better use the two methods described below for testing.

2. Test the network speed on the website
There are many sites that provide the speed test. For websites that are slow in response to the test, the value obtained when testing your network speed will be smaller.

2. ADSL Network acceleration tools

Because Windows system parameters are designed for low-speed access, there is no problem when using Modem to access the Internet. However, when using ADSL, the speed has been greatly improved, and the Windows system parameters have not been changed, so it cannot be well adapted to the data transmission of ADSL access. What we need to do is to modify the default TCP/IP parameters originally set for "low-speed" access in the registry, so as to increase the bandwidth access speed.

Manually modifying the registry is not what cainiao can do. We recommend that you use software for automatic modification. There are two mature tools in this regard: ADSL overclocking and network frenzy.

ADSL Access Network
The "ADSL overfrequency qibing" is designed for ADSL. By modifying the default TCP/IP parameters originally set for low-speed access in the PC system registry, the "ADSL overfrequency qibing" is used to adapt to the PPPoE-based ADSL Access Network. After the software is running, go to the main interface, click the "ADSL Access Network overclocking" button on the left, and then click the "normal overclocking" button to restart the computer for acceleration to take effect, or click the "advanced overclocking" button, on the "advanced overclocking" page, click "Start MTU value verification" in the connected status. After the verification is completed, a dialog box is displayed, showing that the verification is successful. Then, click the "advanced overclocking" button to restart the computer and the acceleration will take effect. It should be noted that the software will modify the Registry in many places. Although the system has a recovery function, we still remind you to use the backup registry before.

After the overclock, I used the Internet Express to download software above kb/s, and solved the stagnation. Although it was not as high as the software author said, it was great. If you are using ADSL, try again. However, this software is only applicable to the PPPoE method of the ADSL Access Network Line and is not suitable for other dial-up access methods and the PPPoA of the ADSL Access Network. Currently, the popular ADSL Access Network Software is basically the PPPoE method, such as Enternet300, RasPPPoE, and WinPoET.
