Completely solve the problem of frequent disconnection instability of ADSL MODEM

At present, adsl modem is widely used. Many people may not understand the problem of frequent disconnection instability of adsl modem. It does not matter. After reading this article, you will certainly have a lot of GAINS, I hope this article will teach you more things. In last October, I installed the ADSL MODEM in both my unit and home to access the Internet. Surfing the Internet on the computer in the office is very effective, fast, and never dropped. When accessing the Internet on the home machine, the network speed is slow, and the connection is often unavailable, that is, the connection is connected, and the connection is often dropped.

I cannot solve this problem because there are no hardware or software problems with the two machines. I have installed them myself, and the operating systems are all installed with genuine Windows XP. When installing the adsl modem, the Telecommunications Bureau is also on site, and the hardware and operating system NIC have not been installed ). The distance between my home office and the office Office is no more than 200 meters from the Telecommunications Bureau's transmission data center. The distance should be the best. The sub-computers in the House cannot access the Internet.

One day, I got online on my office computer. I went back to my home and went online with my computer. I opened my browser, entered the "SOHU" URL in the address bar, and press Enter, "This page cannot be displayed" is displayed on the screen. The page cannot be connected, and the website can be used for trial. after repeated attempts, the page still does not work. When I call my colleagues, I say I can access the Internet, however, my computer cannot be mounted, and the hardware and operating system are okay. The signal lines are normally connected. I thought it was difficult to solve the problem that the ADSL MODEM was faulty. Restart it and unplug the power cord of the ADSL MODEM, after waiting for a few seconds, plug in again, open the browser, enter the "SOHU" URL in the address bar, and press enter, the "SOHU Homepage" page appears immediately on the screen, and you can access the Internet, I tried several other websites again, and it was okay. I thought this time, but after running for more than an hour, I got disconnected again, and restarted the ADSL MODEM to connect again.

After the device is disconnected, restart the adsl modem to connect to the device. If there is a problem with the adsl modem Hardware, then restart the device to connect to the device. There is no problem with the hardware. That is, the running environment problem. The environment is mainly about power supply, because the power supply in the home is not installed as well as the power supply in the unit data center. It is estimated that it is caused by static electricity, connect it to the ground line on the power outlet, and the other side is connected to the iron column on the windowsill. There is no problem when you start the system and access the internet. After several days of continuous operation, no fault has occurred, in order to confirm whether the fault is caused by static electricity, I took the wire and ran the Internet. As a result, the above fault occurred again. I used a multimeter to measure the "Zero Ground" voltage of the power outlet over 40 V, the static power of the chassis is 25 V, which proves that the judgment is correct. After the ground wire is installed, the static electricity of the test Chassis is only about 3 V, and the disconnection fault is solved.

In addition, to solve the problem of slow speed and instability on the adsl modem, we found that using the adsl modem to access the Internet has certain requirements on the telephone line. First, each connection of the line should be properly connected, second, no devices can be connected before the adsl modem splitter, such as telephone extensions and anti-theft tools. After knowing these requirements, I have made corresponding changes to my own telephone line. First, I need to re-connect the wiring column of the corridor cabling box. When re-connecting, I 'd better use fine sandpaper to wipe the telephone line and the wiring post, when wiring, the telephone line on the wiring column more than a few laps, and then tighten the screw, so that good contact. Remove a telephone outlet from your home, and use a direct wiring method. It is best to use welding when connecting the cables and cables, and pack it with insulating adhesive tape. No equipment can be connected before the separator, this ensures good line contact between the distribution box and the adsl modem separator, and ensures the quality of signal transmission.

Through installation of Ground Wires and transformation of telephone lines, the speed and stability of sub-computers in the home have all met the requirements. Using software testing, the author's local network speed to Beijing is: 778.21 Kbps (97.28 KB/second), and the network speed to Hong Kong is: 1069.52 Kbps (133.69 KB/second ). The speed of surfing the internet to watch movies, play games, download software, and visit webpages is very fast. It has never been dropped in three months and runs very stably.

If your organization and the adsl modem at home often have unclear online disconnection or instability, except for computer hardware or software), you do not need professional technical personnel, check your power supply and telephone lines by yourself, and you will not be able to think about it.
