There is also a web page to test the network speed, which needs to refer to the local server.
All the faults of ADSL speed measurement, acceleration and detection have been solved.
ADSL is a high-speed broadband internet access mode running on the original telephone line, which has the advantages of saving investment, fast internet access and simple installation. At present, many LANs, especially Internet cafes, adopt this method. So can this internet access speed reach the speed that ISP service providers say? How can we further improve the speed of surfing the Internet? How to judge whether ADSL works normally? How to find and solve Internet faults? Let's talk about these issues for everyone.
1. How wide is the broadband?
My broadband was installed at the end of 2002. I remember that the customer service staff blew the internet speed very fast at that time, but I found it greatly discounted in actual use. For example, the broadband access service provider promises 1M bandwidth, can it reach 1M? To verify its authenticity, of course, we have to test it. However, there are many factors that affect the test results. For ADSL users, there are mainly the aging degree of telephone lines, the distance between users and telecom room, computer configuration, the performance of connected website servers, the number of people accessing the servers at the same time and so on. For users accessing through local area network, there are mainly the configuration of network card, the number of users accessing, the efficiency of server transfer, the performance of connected website servers and so on. In order to test the objectivity of the results, it is best to choose different time periods for multiple tests and get an average number.
1, use IE to download files to test the network speed.
The simplest test method is to connect to the FTP download service provided by ISP. Download large files with IE, and check the download speed. For example, I use a browser to connect to an ISP's FTP to download files, and the speed is about 70KB per second, which is equivalent to the transmission bandwidth of about 500kbps, which is half as bad as the customer service staff said1m. However, this result is not necessarily accurate. Although the method of downloading files with IE is simple, the test results are not very accurate. If you want to know more about your network, you'd better test it in the following two ways.
2. Go to the website to test the network speed.
There are many websites that provide network speed testing, and Tianxia.com is a very good network speed testing website. It includes many test servers, and its website is www.linkwan.com/gb/broadmeter/SpeedAuto/.. Choose the server you want to connect to, and you will see the test results immediately. This is a cool internet speed thermometer. The test results and the comparison between the results and the standard bandwidth are clear at a glance.
In order to use the test results more objectively, you can first enter the www.linkwan.com/gb/broadmeter/speed/responsespeedtest.htm website to test the response speed of the website. For example, if I want to test the internet speed through Beijing Cocoa Software and point to Cocoa Software with the mouse, I will find that its IP address is 2 10.75.207.52 in the IE status bar. Enter the IP in the test box, and then click the "Test" button to get the response speed of the website. For websites with slow response speed test, you will get a smaller value when testing the network speed.
3. Test the network speed with special tools.
The latest version of SpeedText is 1.3, which is free software. The size of the software is 1. 1MB, and the download address is www.raccoonworks.com/Downloads/SpeedTestInstall.exe.. It can be used to test the connection speed between your computer and a website or server, and the result will be expressed in the form of a histogram: fill in the website address in the "server" column of the main interface of the software, such as www. 163.com, and then press enter to get the test result. If you click the Connect button on the toolbar, you can also test the connection. If you want to compare the result with the standard speed, just select the detailed item in the menu "Compare", such as 786KB(DSL), and you will get a more intuitive result.
Second, ADSL network acceleration tools add fuel to the fire.
Because the system parameters of Windows are specially set for low-speed access, it is no problem to use Modem to surf the Internet. However, when using ADSL, the speed has been greatly improved, and the parameters of Windows system have not changed, so it can not adapt to the data transmission of ADSL access well. What we need to do is to change the default TCP/IP parameters originally set for "low-speed" access in the registry, so as to improve the speed of broadband internet access.
Manually modifying the registry is not something that novices can do. It is suggested that you use software to modify it automatically. There are two mature tools in this respect: ADSL overclocking strategy and netspeeder.
(A), ADSL overclocking Indiana Jones
ADSL Overclocking Raiders is specially designed for ADSL. By modifying the default TCP/IP parameters originally set for low-speed access in the PC system registry, ADSL access in PPPoE mode can be adapted.
After the software runs, the main interface is shown in Figure 4. Click the "ADSL overclocking" button on the left, and then click the "Ordinary overclocking" button, which will take effect after restarting the computer. Or click "Advanced Overclocking" button to enter the "Advanced Overclocking" page, and click "Start verifying MTU value" after network connection, and a dialog box will pop up to show that the verification is successful. Then click the "Advanced Overclocking" button directly, and it will take effect after restarting the computer. It should be noted that the software will modify the registry in many places. Although it has the function of system recovery, we still remind everyone to back up the registry before using it.
After overclocking, all the software I downloaded from flashget was above 200KB/s, and the stagnation phenomenon was solved. Although it is not as double as the software author said, it is excellent. Friends who use ADSL might as well give it a try.
However, this software is only applicable to PPPoE mode of ADSL lines, not to other dial-up Internet access modes and PPPoA of ADSL. At present, the popular ADSL internet software is basically PPPoE mode, such as Enternet 300, RasPPPoE, WinPoET and so on.
ADSL overclocking strategy is a free software. The application platform is Win9x/2000/XP, and the download website is www.worldfax.net.
(2), the network speed (NetSpeeder)
Netspeeder is also a very useful network acceleration tool! Use the automatic settings recommended by the "Netspeeder" wizard to easily improve your network speed, and use the "speed test" function to test and compare the network optimization effect before and after the software application. For various types of network connections (DSL, optical cable, wireless), Netspeeder can fundamentally improve the download speed. DNS Accelerator will update the host name and IP address according to IE favorites and history, which will improve the speed of connecting to common websites.
Optimize actual combat: The main interface of NetSpeeder after running is both simple (guided) and complex (manual).
1, automatic optimization
Using the optimization wizard, you can easily complete the optimization of the network. Click the "Optimization Wizard" button on the left side of the main interface, then click "Next", and then select your network connection type: modem dial-up connection, ADSL connection or cable modem connection. I use ADSL connection, so I choose ADSL connection, click Next, and select Network Interface in the pop-up dialog box. This parameter must be set. This is because the MTU of different interfaces will be stored in different locations in the Windows registry. If you don't know which port to choose, you can select the "All Ports" option, click "Next" and then click "Finish" to save the set optimization parameters in the registry. After restarting the system, you will find that the network speed has been greatly improved. What? You don't believe it? Then please click the "Speed Test" button to test the download speed, and you can see the optimization effect immediately!
2. Manual optimization
If you know TCP/IP parameters very well, you can also set specific optimization parameters by manual optimization, which will definitely have better optimization effect according to local conditions.
Click the "Precise Adjustment" button on the main interface to pop up a dialog box, and select the interface to be optimized in the "Interface" column. In the "MTU" column, you can select a predefined value from the drop-down list, such as "1492- Recommended ADSL", or click the MTU detection button, and the software will automatically find the optimal MTU from the Internet location. Of course, you can also select "Custom" from the drop-down list and set the parameter values yourself.
For dial-up Internet access, the recommended value of MTU is 576, so the MTU probe will specify a value of 576 or less for the Internet location. In case of ADSL, the recommended value is below 1497, and the recommended value of optical cable modem or LAN is below 1500.
Next, set the "TCP receiving window", that is, the size of TCP receiving packets. It is best to set it to an even multiple of the more efficient MSS recommended by the software (such as 2x, 4x, 8x). Generally speaking, a larger received value can better improve its potential performance and obtain higher network bandwidth. The recommended value of general software is MSS * 44 * scaling 4.
Finally, set the "lifetime", which determines the longest time for online storage of IP packets that fail to reach the destination. This is an effective dividing line to determine the number of routers through which IP packets can pass without being discarded. Due to the continuous expansion of the Internet, the suggested parameter is 128. Generally, the value of TTL is less than 128, but if the parameter you set is 0, you can't connect to the network normally.
After all the settings are completed, click the "Apply" button to restart the computer, and you can enjoy faster Internet access.
3.DNS accelerator
The DNS accelerator speeds up by converting the host name of the Internet into an IP address. Click "DNS Accelerator" to pop up the dialog box, click "Add" to increase the host name, and click "Modify" and "Resolve" to correct it.
If you browse the web through IE, Netspeeder can also automatically get the host name from favorites and history and add it to the DNS accelerator. If you want this function, click the Settings tab, and then select the options of Enable DNS Optimization, Automatically Add Hostnames from IE History and Automatically Add Hostnames from IE Favorites in the pop-up window.
Next, we need to set the number of records saved, because Netspeeder will continue to add sites to the DNS accelerator list after we choose to add sites from IE favorites and history. In order not to increase the amount of data, it is best to add only the sites you frequently log in to the list. Finally, don't forget to set the "update frequency", which usually takes 5 days.
According to my test, after using Netspeeder to optimize the network, the speed of broadband (optical cable modem and ADSL) has increased by 2 times, while the speed of ordinary dial-up Internet access can basically increase by about 1 time.
Internet speed is a * * * software, and the download address is www.superhunter.net.
Third, ADSL fault diagnosis and troubleshooting solutions
There are many problems with ADSL Internet access (after all, compared with LAN mode, it is normal for problems to occur due to the addition of ADSL equipment and improper telephone connection). Let's talk about the troubleshooting methods of ADSL first.
1. Factors leading to ADSL failure
The common hardware failures of ADSL are mostly loose connectors, broken network cables, damaged hubs and computer system failures. Generally, you can observe the indicator light to help you locate.
In addition, abnormal voltage, high temperature and lightning strike are also easy to cause faults. In places where the voltage is unstable, it is best to equip the modem with low-power UPS. Modem should be kept dry and ventilated, avoid water shower and keep clean. In thunderstorm weather, be sure to unplug the modem and all connections. Too long line distance, poor line quality and unreasonable connection are also the reasons why ADSL can't be used normally.
2. Find the method of ADSL fault
The fault location of ADSL needs some experience. The general principle is: pay attention to indicator lights and error messages, first hardware, then software, first internal, then external, first local, then external network, first test the host, then test the customer, and declare after full inspection. The fault statement should be accurate and concise, and the problems encountered should correspond to the faults mentioned in the user manual as much as possible. When reporting faults to the computer room, the port number and user name should be reported first according to the user manual. Users should record common faults and mention them when reporting.
(1). Check whether the power indicator is normal.
The power indicator is located at the far left of the three indicators of the user's modem, and it will continue to light normally. If the power indicator goes out, the user can solve the power problem by himself.
(2). Are the data indicators normal?
The data indicator lights are located in two of the three indicator lights on the right side of the user's modem, which continuously lights normally, indicating that there is no fault in the line from the DSLAM client to the local terminal; If the indicator light is not on, it means that there is something wrong with the line, which needs to be solved by the telecommunications department on the spot.
(3) Whether the user network card and network cable are normal.
After the user's PC network card is connected to the modem through the network cable, its indicator light will flash. If the indicator does not flash normally, it means that the user's network card or network cable is faulty.
(4) Check the IP settings of ADSL modem and network card.
The IP address of ADSL modem is set incorrectly, or the DNS server is set incorrectly. Because for ADSL virtual dial-up users, there is no need to set an IP address, which can be automatically allocated. TCP/IP gateway generally does not need to be set. In addition, if the DNS settings are correct, if the operating system is Windows 9x, type Winipcfg in the DOS window to get the DNS address, type ipconfig /renew in Windows 2000/XP, or ask the local telecommunications department.
In addition, TCP/IP settings are most likely to cause the situation that web pages cannot be browsed. For example, you can always browse normally without changing the settings. If you suddenly find abnormal browsing, you can try to delete the TCP/IP protocol and add it again.
(5). Check the dialing software.
There are two ways for ADSL to access the Internet: virtual dialing and private line access. At present, ADSL of individual users mostly adopts the former. And PPPoE (Point-to-Point Protocol over Point-to-Point Protocol over Ethernet) virtual dialing software has its own advantages and disadvantages. After many tests of different operating systems, if the operating system is Windows XP, it is recommended to use your own PPPOE dialing software, which has less disconnection and relatively improved stability. If you are using Windows ME or 9x, you can use the following virtual dialing software-Enternet, WinPoET and RasPPPoE. EnterNet is commonly used now, and EnterNet 300 is suitable for Windows 9x;. EnterNet 500 is suitable for Windows 2000/XP. When you have problems with a PPPOE dialing software, you might as well uninstall this software and replace it with a PPPOE dialing software. Please be careful not to install multiple PPPOE software at the same time to avoid conflicts.
