7. That's because the line in your home is bad, and it's the same as that in my home at night, but my home is in the morning
when I use ADSL to access the Internet, I often encounter such phenomena as web page can't be opened, Download interruption, or online video and audio stream interruption, QQ disconnection, game disconnection, etc. We might as well assume that the landlord is using ADSL to access the Internet. In fact, the reasons why other ways of Internet access are often offline are roughly the same as the following reasons. Now let's analyze the reasons for ADSL offline
first, the line problem
first, check the line at home to see if the connector in the house is connected properly, and whether the line passes through any interference source, such as air conditioner, refrigerator, TV, etc., and try to keep a certain distance from these electrical equipment. It can also replace the indoor lines with more anti-interference network cables. Make sure the wiring is connected correctly. After entering the home, the telephone line is connected to the junction box, and then separated to the voice separator, one line goes to the telephone, one line goes to the modem (the separator is marked). At the same time, ensure that the communication quality of the line is good without interference, and no other equipment that will cause line interference is connected. And check whether the junction box and crystal head have poor contact and whether they are wound in series with other wires. If possible, it's better to use standard telephone line and connect PC with twisted pair attached to ADSL modem. Line is one of the important factors for the quality of image access to the Internet. Signal interference sources such as radio transmitting tower, electric welding machine, tramcar or high-voltage power transformer within 100 meters from the user's cable can make the user offline receive clutter (copper clad steel wire has weak shielding and strong signal receiving ability), causing strong interference to the user's line. The interfered signal is usually the unshielded offline part, because the relay cable has a shielding layer, so the interference and influence are very small. If you use some shielded downlines in places with large interference, it will rece the speed instability or disconnection caused by interference. In addition, the power line should not be paralleled with the ADSL line, in order to avoid crosstalk, resulting in ADSL failure. In addition, there are many other factors that cause network instability, such as signal interference, software conflict. The mobile phone, which has a large radiation, must not be placed next to the ADSL modem, because the mobile phone will automatically find the network every few minutes. At this time, the strong electromagnetic interference is enough to cause the ADSL modem to cut off the current
Second, the network card problem
the network card is usually PCI network card or on-board network card. When you choose, you must choose the one with better quality, otherwise the quality of Internet access may be poor. 10m or 10m / 100M adaptive network card can be used. In addition, many machines share the Internet and use al network cards, which also causes conflicts, which is also worthy of attention. At this time, you should pull up the network card connecting to the LAN or other computers, and only use the network card connecting to ADSL to test the Internet. If the fault returns to normal, check whether there is any conflict between the two network cards
Third, ADSL modem or network card setting problem
now modem generally has two working modes, one is the normal mode of using dialing software, the other is the routing mode of automatic dialing. In normal mode, you don't need to set modem, just use the default mode. The routing mode needs to be set. Modem has its own flash memory, which can save the account and password box settings for automatic dialing. The most common method is to set the IP address of ADSL modem or DNS server incorrectly. Because for ADSL virtual dial-up users, there is no need to set the IP address, which can be automatically assigned. TCP / IP gateway generally does not need to be set. But set DNS must be set correctly, DNS address can be obtained from the local telecommunications department. In addition, TCP / IP settings are most likely to cause the situation of not being able to browse web pages. Generally, it is set to automatically obtain the IP address, but DNS must be filled in. Other default can be used
Fourth, ADSL modem synchronization abnormal problem
check whether your phone line and the ADSL connection are in poor contact, or there is a problem with the phone line, the poor quality of the phone is particularly prone to drop, but this problem is not easy to check, so be sure to use a good quality phone line. If it is suspected that the separator is broken or the ADSL modem is broken, try to directly connect the external line to the ADSL modem without using the separator. The connection between the separator and ADSL modem should not be too long, otherwise it cannot be synchronized. To eliminate the above situation, as long as the ADSL modem is restarted, the synchronization problem can be solved
fifth, operating system, virus problems
in addition to the above-mentioned line conditions, there are also computer system problems. For example, the legendary killer caused the LAN to drop. This problem occurs in a large area all over the country. The virus will affect the Internet cafes (LAN) of host agent and router agent. Legend killer is a destructive software that can cheat LAN by ARP and create virtual gateway address to collect login information of Legend game in LAN and analyze it to get user information. Workflow: first of all, broadcast local Mac to LAN by ARP Cheating, so that the workstation in LAN mistakenly thinks this machine is gateway. This process will cause the connection between LAN and Internet to be interrupted, When the user restarts the game and logs in the account, the account information will not be uploaded to the proxy server directly through the gateway, but will be uploaded to the legendary killer software which is carrying out ARP deception, Attack situation: LAN and Internet link speed suddenly slows down or even breaks down. Online games break off the link, and after logging in again, the server will be prompted that there is no corresponding response. It is suggested to check and kill the virus first; If you have the ability, re install the system; If the machine has two network cards, unload one network card; It is suggested that users who are not familiar with computers should not install all kinds of firewall software at will. Incorrect settings will cause unstable Internet access. Some operating systems may have compatibility problems with ADSL related components, so you can go to Microsoft to upgrade the system or repair the system. If possible, it can be reassembled. If there is a conflict in the software, try to find out the conflict software, uninstall it or solve it by other methods< (6) the firewall and IE browser are not set properly.
although ADSL is less likely to be attacked by hackers and viruses, it does not rule out the possibility, especially web viruses and worms. If the virus destroys ADSL related components, there will also be a disconnection phenomenon. If it can be determined that it has been damaged and attacked by the virus, and there is a disconnection phenomenon, it is necessary to check the installed firewall, proxy server software for sharing the Internet, Internet acceleration software, etc. after stopping running such software, it is necessary to test the Internet to see if the speed returns to normal. If the Internet is not stable, you can try to turn off the firewall first, test whether it is stable or not, and then set it accordingly. In addition, firewall or IE browser failure can also lead to normal connection, but can not open the web page< Seven, static problem
static is an important factor affecting ADSL, and the power supply in the home is generally not grounded, coupled with the interference of various electrical appliances (such as refrigerators, TVS), it is easy to cause static interference, resulting in frequent disconnection of ADSL in use, please lead the grounding terminal of the three core socket out of the wire and make a good grounding, which can generally solve the problem of disconnection. General solution: add grounding wire to solve the problem of disconnection< Eight, software conflict problem
there are two ways for ADSL to access the Internet: virtual dial-up and private line access. Now most of the ADSL of indivial users are virtual dial-up. PPPoE (point-to-point protocol over Ethernet) virtual dialing software has its own advantages and disadvantages. After many tests on different operating systems, if the operating system is Windows XP, it is recommended to use its own PPPoE dialing software, which has less current interruption and relatively improved stability. If you are using Windows me or 9x, you can use the following virtual dialing software -- enternet, winpoe, raspppoe. Among them, enternet is now more commonly used, and enternet 300 is suitable for Windows 9x; Enternet 500 is suitable for Windows 2000 / XP. When you have problems with one PPPoE dialing software, you may as well uninstall the software and use another PPPoE dialing software. Please be careful not to install multiple PPPoE software at the same time to avoid conflicts. Because the telephone line is the main way of broadband access, so we must set up a virtual channel. If several kinds of dial-up software are mixed, it will cause conflicts, resulting in network instability. If there is a conflict in the software, try to find out the conflict software, uninstall it or solve it by other methods. For example, some friends BT download will lead to network offline. It may take too many threads to download, resulting in disconnection
in addition, besides the above reasons for your own computer, the reasons for QQ and game offline may also be related to their own server restrictions and server attacks or failures<
fault analysis
in general, there are several reasons for ADSL modem dropping: line quality problem, ADSL modem heat dissipation problem and excessive flow
first, check the line. The telephone connected with ADSL is clear without noise, the wiring is correct, and there are no high-frequency electrical equipment around. During the startup of ADSL modem (including the disconnection), the indicator light is normal, so the problem of line quality is eliminated. Secondly, when it is found that the ADSL modem is off-line, test its temperature immediately. It feels slightly hot and the temperature is normal. Because it is also connected to four computers, so unplug the connection with the other three computers, leaving only one computer online, the fault is still, which can eliminate the possibility of the fault caused by excessive traffic
is there something wrong with the routing of ADSL modem. I set ADSL modem as dial-up through configuration program, and then use computer dial-up to access the Internet, everything is normal. Is the route of ADSL modem broken? At this time, the author found that the software firewall is constantly alarming. It shows that there are multiple IPS continuously connecting to ports 135, 445, 2745, 6129, etc. The author has finally found out the cause of the failure. When the Internet is connected through routing, the IP address of the public network (Internet) is bound with the ADSL modem. Because the NAT (network address translation) is not turned on, the external connection request for this address actually acts on the ADSL modem. The ADSL modem is running at full load when it carries out data transmission and routing, When a large number of connection requests are encountered, the computing power will be insufficient, resulting in offline
solution
first, set the IP address of the computer and ADSL modem in the same network segment. Then enter the web management page of ADSL modem. Click the "NAT" option in "services" on the page, select "enable" and then click the "submit" button. Then, click the drop-down menu on the page, select "NAT rule entry", and then click the "add" button on the page. The window of adding NAT rules will pop up, and select "bimap" in the "rule flavor" column. In the "rule ID" column, fill in a number larger than the ID of the existing rule (ensure that this rule is the last rule, and the original rule does not need to be changed). In the "local address" column, enter an address that does not exist in the local area network, and then click the "submit" button
