Computer broadband is often disconnected from the server. What is the reason? Is it network or computer?

Why is your computer always disconnected from the Internet? The line is disconnected every few minutes.

What's going on here? " `? ``/Help me/"? "? Everybody! !

It may be a problem with the network provider.

Is your computer cable a network cable or a network cable?

I don't need to say ``` haha.

Let's talk about the network messenger.

Line problem

First, make sure the lines are connected correctly. After the telephone line enters the home, it is connected to the junction box and then separated by the voice separator. One line is connected to the telephone and the other line is connected to the modem (marked on the separator). At the same time, ensure the communication quality of the line is good, free from interference, and do not connect other equipment that will cause line interference. And check whether the junction box is in poor contact with the crystal head and whether it is entangled with other wires. If possible, it is best to use a standard telephone line to connect the PC to the twisted pair of ADSL modem. Line is one of the important factors that affect the quality of image browsing.

Network card problem

Network cards are generally PCI network cards or onboard network cards. When you choose, you must choose a better quality, otherwise the quality of the internet may be poor. You can use 10M or 10M/ 100M adaptive network card. In addition, many machines * * * like surfing the Internet and use dual network cards, which also causes conflicts. It is also worthy of attention. At this time, you should unplug the network card connected to the LAN or other computers, and only use the network card connected to ADSL for online testing. If the fault returns to normal, check whether there is any conflict between the two network cards.

Improper selection or mixed installation of dialing software

There are two ways for ADSL to access the Internet: virtual dialing and private line access. At present, ADSL of individual users is mostly virtual dialing. 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. Because telephone line is the main way of broadband access, a virtual channel must be established. If several dialing softwares are mixed, there will be conflicts and network instability.

ADSL modem or network card setup problem.

At present, modems generally have two working modes, one is the normal mode of using dialing software, and the other is the routing mode of automatic dialing. In normal mode, you don't need to set up a modem, just use the default. The routing mode needs to be set, and the modem comes with flash memory, which can store the account number and password box settings that are automatically dialed when the computer is turned on. The most common method is to set the wrong ADSL modem IP address or set the wrong DNS server. 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. But DNS must be set correctly, and the DNS address can be obtained from the local telecommunications department. In addition, TCP/IP settings are most likely to cause web pages to be unable to browse. Generally, it is set to automatically obtain the IP address, but DNS must be filled in. Others can use the default settings.

Abnormal synchronization of ADSL modem

Check whether your telephone line and ADSL connection are in poor contact, or there is something wrong with the telephone line. Poor-quality phones are particularly easy to drop, but such problems are not easy to find, so you must use a better quality phone line. If you suspect that the splitter or ADSL modem is damaged, please try to connect the external line directly to the ADSL modem without using the splitter. The connection between the splitter and ADSL modem can't be too long, otherwise it can't be synchronized. Excluding the above situation, the synchronization problem can be solved by restarting the ADSL modem.

Operating system problems

Some operating systems may have compatibility problems with ADSL-related components, so you can go to Microsoft to upgrade or repair the system. Conditional can be reloaded.

Firewall (virus) settings are incorrect.

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, the network will be disconnected. If it can be confirmed that the network is still disconnected due to virus damage and attack, it is necessary to check the installed firewall, * * * * proxy server software, Internet acceleration software, etc. After stopping running this kind of software, test it online to see if the speed returns to normal. If the internet is unstable, you can try to turn off the firewall first, test whether it is stable, and then make corresponding settings.

In addition, there are many other factors that lead to network instability, such as signal interference and software conflict. Mobile phones, which radiate a lot, must not be placed next to ADSL modems, because every few minutes, mobile phones will automatically search the network, and at this time, strong electromagnetic interference is enough to cause the ADSL modems to lose power. If the software conflicts, try to find out the conflicting software, uninstall it or solve it in other ways.

Finally, there is a virus called magic wave phenomenon: it prompts many error messages such as memory errors, and automatically hangs up in about 20 minutes.

If there is a route, there are many kinds of pull.

Poor power contact, right?
