Stability of access to ADSL Optical Fiber Access Network

There are still many things worth learning about in the ADSL optical fiber access network. Here we will mainly introduce the analysis of problems such as unstable ADSL optical fiber access network lines. When you carefully check the status of the ADSL optical fiber access network MODEM, you will find that the dial-up login is successful. So what exactly is the problem? How Should ADSL users troubleshoot? Web pages cannot be opened, downloads are interrupted, or online video and audio streams are interrupted. These problems may cause many users to access the Internet through ADSL.

Unstable line

If the domicile is too far away from the Telecommunications Bureau (more than 5 kilometers), you can report to the telecommunications department. Ensure that the line connection is correct (the connection methods for different voice splitters are different. Please follow the instructions to connect correctly ). At the same time, ensure that the communication quality of the line is good and there is no interference with other devices that may cause line interference, such as telephone extensions and fax machines. Check whether there is poor contact between the junction box and the crystal head, and whether there is any link with other wires. It is best to use standard telephone lines if conditions are met. It is better to use twisted pair cables of category 3, Category 5 or category 5 of ITU standards. The telephone lines are separated after they are entered. The first line is telephone and the first line is computer. If you want to install a telephone extension in your room, you 'd better select a good distribution box. The PC is connected to the twisted pair Cable attached to the ADSL Modem. Note: The mobile phone must not be placed next to the ADSL optical fiber access network MODEM, because the mobile phone will automatically find the network every few minutes. In this case, strong electromagnetic interference is enough to cause the ADSL Modem to be disconnected.

Knowledge about Nic purchasing

Check your network card. If it is an ISA network card, you 'd better switch to PCI and select a good quality network card. A poor network card may be the cause of the problem. 10 M or 10 M/M Adaptive Nic. In addition, it is also worth noting that dual NICs cause conflicts. In this case, you should unplug the network adapters connected to the LAN or other computers and use only the network adapters connected to the ADSL optical fiber access network for Internet access testing. If the fault returns to normal, check whether two NICs conflict with each other.

Incorrect MODEM or Nic settings for ADSL Optical Fiber Access Network

The most common problem is that the IP address of the ADSL Modem is set incorrectly or the DNS server is set incorrectly. Because the user of ADSL virtual dialing does not need to set an IP address, it can be automatically allocated. Generally, TCP/IP gateways do not need to be set. In addition, make sure to set DNS correctly. If the operating system is Windows 9x, enter Winipcfg in the DOS window to get the DNS address, and enter ipconfig/renew in Windows 2000/XP, or ask the local telecommunications department. In addition, the TCP/IP settings are the most likely to cause the inability to browse the Web page. For example, if you have not changed the settings, you can always browse normally and suddenly find that the browsing is abnormal, you can try to delete the TCP/IP protocol and then add the TCP/IP protocol again.

An error occurred while synchronizing the MODEM of the ADSL optical fiber access network.

Check whether your telephone line is not in good contact with the ADSL connection, or the telephone line is faulty. If you suspect that the splitter is bad or the ADSL Modem is bad, try to directly connect the external line to the ADSL Modem without using the splitter. If it is determined that there is no problem with the separator, ensure that the connection between the separator and the ADS LModem should not be too long. If it is too long, it is very difficult to synchronize. If the above conditions are excluded, you only need to restart the ADSL Modem to solve the synchronization problem.

Operating system defects

Some operating systems may have compatibility problems with components related to the ADSL optical fiber access network. Taking Windows 98 as an example, its network components have major defects, which may cause inexplicable disconnection during network connection. In this case, the best solution is to patch the system. You can directly connect to Microsoft's official website and select the patch downloaded from the system. After the patch is installed, install the virtual dialing software.

Major patches include: Windows 98SE patch, Windows 98 dial-up network 1.3 upgrade 1.4 patch, Windows 95 was used at that time WinPoET, for software such as RasPPPoE that works on the * Operating System's dial-up network, first install "Microsoft dial-up network 1.3" to work normally, and Microsoft dial-up network MSDUN1.4.
