What to do with broadband dial-up outages?

In the use of ADSL sharing dial-up networking environment, there are often inexplicably download interrupt phenomenon, the Web page can not open the phenomenon or the phenomenon of online multimedia streaming suddenly interrupted, and so on, these phenomena are believed that most users who use broadband dial-up often encounter.

However, when these phenomena occur to the ADSL modem for careful examination, we will see the dial-up login is in a successful connection state. What is the problem that causes the above phenomena to occur frequently? In fact, the above several dial-up Internet failure is caused by the flow of the process of broadband dialing, we just follow the following methods to conduct a multi-angle, all-round to the investigation, can effectively avoid the strange on the Internet fault!

Check the network card quality is perfect

Regardless of the way the Internet is used, the quality of the NIC directly affects and determines the performance of the network connection is stable. In order to ensure that the network card work as stable as possible, we would be better to use the ISA network card has been used to replace the PCI card, in the purchase of network card when possible to choose the brand products, can not excessively pursue low price products, after all, the brand influence of the network card or the price is too All have the potential to cause the emergence of various network failures. In addition, in the same workstation, try not to install two or more than two network card devices at the same time, because more than one network card installed when the resource conflict is very easy to occur, once this phenomenon, network card equipment Even if it can barely work, its working status is not very stable. Therefore, when we encounter dial-up Internet instability phenomenon, we must check whether the workstation installed at the same time a number of network cards, if it is the case, we should connect LAN or other workstations to remove the network card from the system, only to connect ADSL modem network card equipment for online testing, If the phenomenon is resolved immediately, it means that the flow of the broadband dialing process is the result of multiple network card conflicts.

Of course, the degree of contact between the NIC and the motherboard slot can also affect the stability of the dial-up connection. To ensure that the network card is able to contact closely with the motherboard socket, we have to install the network card before, we must first check whether there is dust or foreign body in the corresponding slot of the motherboard to prevent the plug in the slot to affect the smooth insertion of the network card, even if the network card can be reluctantly inserted into the slot, the network card will not be close contact with the bottom This makes it easy to cause the NIC to not work properly. If the computer board is "in service" for a long time, its slot may accumulate a thick layer of dust, the two sides of the reed elastic may also be gradually lost, these will affect the network card and slot close contact; In addition, if the network card is inserted into the slot of the angle of the wrong words or force more fierce words, It is possible to bend the reed on either side of the socket to affect the smooth insertion of the NIC.

Check that the connection line is stable

As the internet signal needs to be transmitted through the connection line, if there is bad contact in the connection line or frequent outside interference, then the process of broadband dialing is more likely to occur.

Generally speaking, the reason that the dial-up connection line is unstable, mostly is the network connection line contact unreliable cause, this includes network connection line own problem and crystal head problem. To this end, in the elimination of this fault phenomenon, we should first use the network wire detector to connect the cable connectivity performance test, if the line connectivity performance is not good, it is likely that the twisted-pair quality or cable in the middle of disconnection or short connection phenomenon, at this time must be reconnected with other good connectivity cable to connect the computer; If the test found that the crystal head loose caused by the instability of the dial-up connection, we can replace a crystal head. And the contact between the Crystal Head and network card if it is not good, it may also cause dial-up connection instability of the phenomenon. Of course, in the specific line connection operation, we must pay attention to the use of different voice separator, their specific connection operation may not be the same, we must strictly follow the instructions to the operation of the correct connection, and can not be based on their experience at random connection; Moreover, in order to prevent the communication connection line is interfered by the outside communication, we try not to connect the telephone extension, the facsimile machine and so on in the dial-up connection line the equipment.

Check to see if the operating system is working

The operating system mentioned here is normal, mainly refers to the current workstation is used by the operating system is compatible with ADSL dialing related devices. For example, if a workstation has a Windows 98 operating system installed, the ADSL modem device connected to the system is prone to disconnection, which is the result of the Windows 98 operating system's incompatibility with ADSL network components. In order to improve the working stability of ADSL modem equipment, we should choose the workstation with Windows XP SP2 operating system as the dial-up host, because the system has the best compatibility to ADSL related equipment, and the stability of ADSL modem equipment is the best when working under the system. Of course, if we do need ADSL dial-up Internet access under the Windows 98 operating system, it's best to download a dedicated stop-through patch on the web, which can be downloaded directly from Microsoft's official website, and then properly installed in the Windows 98 operating system. As a result, we will not be able to easily stop the flow when we make a broadband dial-up operation in the future.

Check to see if the dialing program is disturbing each other

In general, through the ADSL device to connect to the Internet network mainly has a dedicated line access and virtual dial-up, and most ordinary users are using virtual dial-up this way to the Internet, the use of this way on the internet when the job stability of the dialer has become a key factor. After the operation test in the different system environment, we found that in the Windows XP system environment chooses its built-in PPPoE dialing program, the broadband dial-up is very few to have the cut-off phenomenon, the dial-up network stability is also relatively high;

In the Windows 98 or Windows Me system environment, we try to choose a virtual dialer such as WinPoET, Enternet, where we try to choose EnterNet300 Programs in Windows 98 environments, in Windows 2000 system environment, as far as possible choose Enternet 500 program. If ADSL does not successfully dial the Internet when using a particular dialer, we may consider uninstalling the dialer completely from the system and then selecting another appropriate virtual dialer, and never install multiple virtual dialer in the workstation system. In this way, it is easy to cause the dial-up Internet to appear strange trouble phenomenon.

In addition, we often use a number of applications also easily lead to ADSL dial-up disconnection phenomenon, such as the frequent use of QQ 2000b program, it is easy to ADSL dial-up Internet stability caused by interference, in order to avoid this interference we'd better remove the program from the system clean. As for what other software will cause the dialing cut-off phenomenon, we need to further detect, test.

Check the ADSL settings are correct

If we use the ordinary ADSL modem equipment, and the device built in the routing function enabled, then we use Peer-to-peer software from the Internet to download information, it is very easy to dial off the phenomenon, the reason for this phenomenon, mainly ordinary ADSL Modem equipment with its own routing function can not meet the Peer-to-peer software needs of the network performance, so dial-up when the internet is often a cut-off, drop the phenomenon. In order to avoid the dialing cut-off caused by this factor, we can before using Peer-to-peer software, first login to the general ADSL modem Equipment Background Management interface, the device to temporarily shut down the routing function, and the ADSL modem equipment restart, In that case, when we use peer-to-peer software to download information from the Internet, it is not easy to stop the flow of trouble. In addition, we in the ADSL modem Equipment Background management interface, as far as possible the device's IP address set to static address, at the same time its own DHCP function off, in order to prevent the occurrence of IP address conflicts caused by the Internet often drop line.

Check if network virus exists

If the above operation we have successfully checked, ruled out, ADSL modem equipment still appear cut-off, drop line phenomenon, then we estimate most likely is the local workstation system appeared network virus, because some viruses can easily lead to ADSL modem equipment cut-off, drop line phenomenon. To this end, we can regularly use the latest version of anti-virus software to the workstation system for a thorough virus killing operations, after the virus is finished, but also need to install the local system on the original security firewall, in order to prevent network viruses attack ADSL modem equipment, affecting the stability of our dial-up Internet.
