The use of ADSL modem fault

1, why the ADSL modem in the link lamp has been flashing state?

Answer: ADSL modem in the flashing state of the link lights, indicating that the line signal is not stable, if after a period of time to return to normal, it shows that the flashing state of the link lamp is part of the telecommunications parts of the adjustment caused by the local line. If the link lights have been flashing state and can not return to normal, it is connected to the ADSL modem communication line has failed; At this time we can check whether the telephone line has a signal, if the line has a signal, it means that the phone line is normal, if not detected line signal, To indicate that there is a problem with the line, you must ask the line maintenance staff to help troubleshoot the line; If the line signal is normal, the link lamp in the ADSL modem is still blinking, it is a port problem, we can contact the staff of the telecommunications department, let them reset the network port, In general, reset network port will have a signal, if through the above processing, can not solve the problem, you need to consider the replacement of ADSL modem equipment.

　　2, why the ADSL modem signal illuminated steady, you can dial the normal situation, not normal browsing page?

Answer: Since the ADSL modem can be normal dial-up connection, it means that there is no fault on the Internet equipment, because once the device problems, we will not connect to the success of the dial. Web page content can not be opened, it is likely that the network settings issues. At this point, you can use ping to check the network card and modem IP address, to see the parameters of the network card is correct, under normal circumstances, these two IP addresses should ping, if there is a can not ping, it shows that network equipment failure; If you can ping the IP address above, if you can't open the Web page, check the current DNS network parameters to see if the DNS server is set up correctly; Some users can solve the problem by this method, and if some users have a firewall installed in the system, they should try to turn it off. If the above method still can not solve the problem, then check whether to enter the ADSL Modem Equipment Control Interface, if you can not enter the setting interface, it is a system problem, you can try to reinstall the system, and correctly configured the relevant network parameters, including IP address and DNS server; Generally speaking, as long as the reinstall system and set the network parameters, can access to the ADSL Modem Equipment Control interface, and as long as can enter the ADSL Modem Equipment Control interface, generally can open page page.

　3, why ADSL modem signal is in the normal working state, but is not dial-up Internet?

Answer: Because ADSL modem signal light is in the normal working state, indicating that the line of the home has signal transmission; At this time we should check the ADSL modem equipment LAN lights status, if the LAN light is not bright, on the ADSL modem equipment and network card connection problems, This will not be able to dial correctly, in this case, you can try to change the network card. If you find the LAN light illuminated steady and cannot dial correctly, you can completely uninstall the original dial-up software from the system, and then reinstall the Dial-up software in the correct way, and make sure that you use the correct username and password. If you can not make a dial-up connection, you will need to reset the ADSL modem equipment down, so that the ADSL modem all the network parameters back to the default settings. On the ADSL modem, we find a round hole about 2 mm in diameter, then in the case of power, with the ball-point pen core things such as poke in, so that we can feel a button was pressed down, so that the state lasts more than 10 seconds, you can restore the parameters to the original factory value. If the reset button is not correct to restore the parameters, you can open the ADSL Modem Equipment Control Interface, the implementation of the "Reset to factory default" command for software reset. Because many users in the operation of ADSL modem process, often appear incorrect shutdown or other improper operation, such as the ADSL modem when the switch is not through the button and unplug the power cord, it is easy to make ADSL modem internal software generated confusion, so about ADSL Many faults in modem can be solved by the method of resetting.

　　4. Why is it very slow to access a Web page when the dial-up connection is normal?

Answer: Generally encountered this type of failure of the user is basically those 1MB users, download the speed of only 20KB below, and the normal download speed should be 80KB to 100KB between; To solve such problems, we should ask telecom engineers to test the line for themselves, If the line is too long over 3 kilometers, it can't be measured. When the confirmation line is not faulty, we can use the laptop home to the Internet, to see how the download speed in the end; if you download the Web page with a notebook, the speed is normal, it means that their original computer system has problems; if the speed of downloading pages with a notebook is not up to normal standards, So we're going to the measuring station to find the port that connects to your home, directly from the port jumper out, and then in situ at the measuring table on the download speed test, if the test on the measuring table is not normal speed, it is the telecommunications sector port problems, as long as the replacement of a new port can solve the problem. If the test at the measuring table to download the speed is very normal, it will indicate that the problem is in their own home line; You may wish to consider rewiring.

　　5, why in the ADSL modem signal is in illuminated steady state, dial-up connection is frequent drop line?

Answer: If the frequent drop is only a recent accident, perhaps the telecommunications sector in the line adjustment, you may wish to wait a few days more patiently. If this phenomenon has not been improved, it is necessary to carry out a specific analysis. For example, the Internet time more than 2-3 hours before the line off, I think this situation is quite normal, after all, ADSL is connected to the Internet through the telephone line, so this situation is inevitable to drop the line. If you just go online and drop the line, it means that there is a problem with the line, if we can not correct, the author suggested that the staff of the telecommunications department to come to the line to test, if found to be faulty lines on the wiring, if the modem has a fault should be replaced by the new modem.

　　6, why after the successful installation of ADSL, found that a phone came in, the line will automatically fall off and there is a lot of noise appear?

Answer: The reason for this failure is likely to be used in the home is the extension, and connected to the extension of the telephone line has not been connected through the separator, you may wish to connect the extension of the line to install a separator, if the line is connected with a separator, Members of the telecommunications department can be asked to check whether there is a problem with the separator, if there is a failure, you should replace the new separator.
