First, answer common broadband questions.
1. Why do you often get disconnected when surfing the Internet?
ADSL disconnection involves several problems, including line failure (line interference), modem failure (fever, quality, compatibility), network card failure (slow speed, outdated drive) and so on.
When your ADSL is disconnected, you can do the following:
1) requires that a separator (filter) must be installed before each telephone extension, preferably no more than two extensions. Please don't use the telephone line that is not connected to the extension.
2) The quality of the network card is unstable. The fault phenomenon is that once the network is disconnected, it can't be connected again. If the line synchronization light of the modem is on all the time, the fault of the external line is basically ruled out, and most of the problems are on the network card. If the problems of network cable, microcomputer and slot are eliminated, the quality of network card is generally unstable, please replace the network card in time.
3) surfing the internet and talking cannot be done at the same time. The fault phenomenon is that the microphone network will be disconnected when it is lifted. Generally, the external insulation is poor or the connector contact is poor, or the quality of the separator is poor.
4) Incorrect telephone extension connection. Because the telephone extensions are not connected in series correctly, resulting in crosstalk and disconnection, generally do not connect the telephone extensions in front of the separator. If you want to connect, please connect the extensions from the back of the separator.
5) The modem is hot. Because the modem is not turned off for a long time, overheating of the modem will also lead to unstable internet access. It is suggested that when you are not surfing the Internet, try to turn off the power of the modem.
6) There are high-power electrical equipment beside the modem, which is easy to cause signal interference. It is recommended that you don't put some electrical equipment such as mobile phones and refrigerators next to the modem. Never put the turned-on mobile phone next to the modem, because the mobile phone will automatically search the network every few minutes, and strong electromagnetic interference is enough to cause the modem to lose power.
2. Why is ADSL not as fast as expected in download speed?
It's mainly about the rate unit. For example, the maximum download rate of the so-called 56K modem is only 5 ~ 6k. The unit of 56K is bit, and the rate display when downloading is byte. 1 byte = 8 bits. So when the download shows 120KB, it has actually reached 120K*8BIT=0.96Mbit, which is quite fast. In addition, the download speed is also related to the website server and the number of visitors. It is suggested that downloading tools should be used as much as possible when downloading large files, and do not choose busy network hours. Sometimes the webpage is slow, try to open another website first. If it is soon, it may be because of the website server you visited. Please try again later. If it is also slow, it is recommended to check the memory and cpu usage of the computer. If the usage rate is high, you may get a virus. It is recommended to kill virus first.
3. What is ADSL account binding and what is its significance?
ADSL account binding is to bind the ADSL user account (user name and password) to a fixed ADSL line, so that the account cannot be used on other ADSL lines, which is of great significance for ensuring account security and preventing others from stealing.
4. Why can't I surf the Internet or make a phone call?
Users should first check whether the telephone incoming connector is loose. If there is no fault, the telephone line may be blocked at this time. Please call China Telecom customer service hotline 10000 to report the fault in time.
5. Why can't I make phone calls and surf the Internet?
When users surf the Internet, don't dial the number as soon as the modem is turned on, otherwise an "Error 678" prompt will appear. This is because after the modem is powered on, there is a process of self-checking and negotiation with the terminal equipment of the telecommunications bureau, which generally takes more than 20-30 seconds. It's best to turn on the modem first, and then dial when the synchronization light is on. Please check whether the synchronization light on the modem is normal first. MODEM is widely used in Xuzhou market now.
Types are Alcatel, Daya, Putian, etc.
Putian modem: ten thousand "link" lights: the green light is always on to indicate synchronization; LAN "link/act": displays whether the connection between modem and network card or hub is normal. If this light is not on, it means that the modem and the computer are definitely not connected; "PWR" light: power supply display.
Alcatel modem:; Synchronization indicator SYNC: This indicator should always be green during normal operation, and LAN status indicator LAN: When data flows into or out of the LAN interface behind the modem, this indicator will flash green. Goose modem: the "link" light is always on, indicating synchronization. If the modem is synchronized, another common fault is that the network card is disabled or damaged. For users who use WINME, WIN2000, WINNT and WINXP, because they don't need to restart their computers to change the network properties, some users mistakenly disable their network cards and can't surf the Internet, so they just need to re-enable the local connection in the network and the dial-up connection of "My Network Neighborhood". If not, please reinstall the network card.
In addition, it takes 5 minutes to redial after abnormal disconnection (such as sudden computer crash and sudden power failure of modem). This is because the original record of normal communication is still kept in the machine of the telecom company, and the equipment will reset the signal after 5 minutes without detecting the user signal.
6. Why doesn't the dialing software work properly?
ADSL needs special dialing software, so RASPPPOE software is recommended. Under the Win XP operating system, you only need to use the dial-up software that comes with Windows XP to install it. The method is as follows: Start-Control Panel-Network or Internet Connection-Network Connection-Create a new connection in the network task-Select the first item to connect to the Internet-Select the second item to manually set my connection-Select the second item to connect with a user name and password-Enter the name and password-Finish; In other operating systems, to install RAS PPPOE, just double-click Install PPPOE095.EXE and select Yes.
After the installation is completed, the dial-up connection interface of "Connect to" will automatically pop up, enter the user name and password, and you can dial-up the Internet.
7. Why does the mobile phone have noise after installing ADSL?
It is required that a separator (filter) must be installed before each telephone extension, and it is best not to exceed two extensions. The following figure shows the wiring methods of various separators:
At present, there are two kinds of common filters in Xuzhou market, one is double-port and the other is three-port. For a splitter (filter) with three jacks, these jacks are: line port, telephone port and DSL (modem) port.
O-port: used to connect the telephone line of the telecom company.
O telephone port: user telephone interface.
O Modem port: connected with the modem interface.
For a separator (filter) with two jacks (or plugs), the two interfaces are line port and telephone port respectively.
O-port: used to connect the telephone line of the telecom company.
O telephone port: user telephone interface.
8. Why can I dial the Internet but can't open the webpage?
(1) Click "Start" with the left mouse button, then click "Run", then enter "ping202.102.13.141-t", and click OK to see if you can ping. If you can ping, the response message is:
Reply 202.102.13.141byte = 32 Time = 100 ms TTL = 249, then the IE browser is set incorrectly or the network card is set incorrectly. If you can't ping, reply to the message: the request timed out. At this time, it is best to restart the computer and the modem to redial. If it still doesn't work, please call China Telecom customer service hotline 10000. (In some win2000 systems, it takes several minutes to open a webpage after connecting to the Internet, which is the reason for win2000 systems. )
(2)ADSL dial-up users do not need to set IP. Telecom companies have configured preferred DNS and standby DNS in the access server. After the user's dial-up authentication is passed, the IP address and DNS address will be returned to the user, so no other configuration is needed when installing the user except PPPoE software.
(3) Some users use the Internet assistant in 372 1 and have an option to block advertisements. If ` is enabled, the secondary link cannot be opened, so just remove it.
(4) It is best not to upgrade or uninstall the programs that come with WINDOWS, which will make the system unstable. Restoring with the system installation disk should solve the problem.
(5) Users are advised to install anti-virus software on their computers to find and kill viruses in time.
9. What is a computer virus? The computer may be infected with a virus or attacked. What should I do?
Computer virus is only a very destructive program, which mainly affects the operating efficiency of the computer and will not have any impact on the human body. It is essentially different from the virus mentioned in human daily life.
When the computer is infected with virus or attacked, the network access speed may be reduced or even inaccessible, and the data on the user's computer will be destroyed and illegally stolen, which will also affect the normal internet access of other users in the same LAN. After a computer is infected with a virus or attacked, the following phenomena may occur:
(1) After the computer is turned on, it will automatically shut down and restart during or after startup.
(2) The running speed of the computer obviously slows down, and the CPU utilization rate rises rapidly to 100%, so some applications can't be opened.
(3) The computer crashed shortly after it started, and the hard disk light kept flashing.
(4) Strange images appear on the computer screen or some strange things are automatically prompted.
(5) After surfing the Internet, many secondary links can't be opened or some pages automatically open endlessly.
In order to avoid this situation. Ask users:
(1) Set a password for your computer and keep it safe;
(2) Go to Microsoft website to upgrade the patch operating system (Windows) in time;
(3) Turn off unnecessary protocols (such as NETBIOS) and * * * shared ports on the computer;
(4) Install personal software firewalls, such as "Skynet" and "Rising";
(5) Install antivirus software (such as Kingsoft Internet Security, Rising, KV, etc.). ) and timely upgrade regular antivirus.
The above methods can effectively protect the security of personal computers. If users have higher requirements for security, they can consult relevant network security consulting companies.
10, why can't I watch online movies?
If "Close" appears many times, it may be a new movie with too many viewers. It is recommended to order later; If a movie doesn't open at all, I suggest you try another movie. If many movies can't be opened, you can contact the telecom company to handle them. If you log on to the internet for the first time and find that you can't open any online movies, it may be that the user doesn't have a plug-in to play movies, or the version of the screening software is too low. Please go to Pengcheng Window (www.856 16.com) to download the related playing software. It may also be because the computer has insufficient memory or the sound card is not installed successfully. At present, the video source is generally compressed into 750K/S data stream, and the machine with CPU lower than PIII may not be able to watch it. When watching online movies, users occasionally have a short buffer, as long as it is not very frequent (for example, it will be interrupted every 3-5 minutes). In addition, too low computer configuration, improper software installation or too many junk files may cause movie buffering.
1 1. How to modify the service password and query password after surfing the Internet?
Log in to the online business hall or log in to Pengcheng Window-Password Bill-Service Password to modify the online password. Just fill in the xz phone number or 05 16 phone number @adsl (must be in lowercase) in the customer name column, and the internet password will be modified at this time. (After modification, you should also fill in the new password in your own dialing program). What is modified in "Query Password" is the password for users to query online time. (The user name entered is also xz phone number or 05 16 phone number @adsl must be lowercase).
Second, common broadband error codes and elimination methods
1, error code 69 1
Treatment method:
The prompt of 69 1 may be caused by the wrong user name and password. First, check whether your user name is: xz phone number @adsl (or 05 16 phone number @adsl, which must be lowercase), and then make sure that the password is not filled in incorrectly or modified by other family members. Passwords are case-sensitive, so pay special attention. If you forget your password, please bring your phone account holder's ID card to the telecom business hall to modify it or call China Telecom's customer service hotline 10000. If the same prompt 69 1 still appears, it may be caused by arrears of online banking accounts or dead accounts. You can call China Telecom's customer service hotline 10000 to make inquiries or declare obstacles.
2. Error code 678
Treatment method:
If you encounter the error prompt of 678 in the process of surfing the Internet, you can check it step by step according to the following steps.
1. First, check the status of the modem to determine whether it is normal.
2. Under normal circumstances, turn off the power of the modem for 5 minutes, then restart the computer and try again; When the modem is abnormal, please turn off the power supply of the modem first, and check whether the network cables between the modem and the network card and between the modem and the separator are connected correctly.
3. When restarting the modem is ineffective and the modem light is normal, it is recommended to uninstall the network card driver and dialing software and reinstall it.
4. If 678 is still prompted, please call China Telecom customer service hotline 10000 for fault repair, and we will send someone to check the line for you.
3. Error code 769
Treatment method:
The 769 fault usually occurs in xp operating system because the local connection in the computer is disabled. You just need to restart the local connection to get back to normal. First, please find an "Online Neighborhood" icon on your computer desktop. Next, click the online neighbor directly with the right mouse button, then click Properties with the left mouse button and then double-click the local connection, and the system will automatically enable the local connection. When the local connection is started, you can access the Internet by redialing.
4. Error code 6 19
Treatment method:
It is recommended to restart the computer and reconnect the modem line. If you still can't get back to normal, please uninstall all PPPoE software and reinstall it.
5. Error code 7 18
Treatment method:
The 7 18 error usually occurs when the server fails, indicating that the verification information has been successfully sent, but the response information returned by the server cannot be received, and the line connection is normal. It is suggested to try again later. It should only be caused by the busy server.
6. Error code 734
Treatment method:
It is recommended to restart the computer and reconnect the modem line. If you still can't get back to normal, please uninstall all PPPoE software and reinstall it.
7. Error code 797
Treatment method:
It is recommended to restart the computer and reconnect the modem line. If you still can't get back to normal, please uninstall all PPPoE software and reinstall it.
8. Error code 735
Treatment method:
The IP address set by the user conflicts with the IP allocated by the bureau. It is suggested that the user choose to automatically obtain the IP address or reinstall the dialing software.
9. How to judge whether the modem is in a normal state?
When dial-up cannot connect to the network, please check whether the modem is in normal state. When the modem is in a normal state, the modem will have two or three indicator lights in a long light state. They are power light, line light and network card light. The indicator lights of different models of modems may have different names and signs. The names and logos of some modems are listed below. For more information, please refer to the instruction manual of your modem.
If any one of the power lights and line lights goes out or flashes, it is not normal. Usually, you can turn off the power and restart the modem (some modems have a power switch behind them). After 2 minutes, when the lamp of the modem is stable, if it is abnormal, you can refer to the following solutions.
(1) power light: If it doesn't light up, it may be that the power supply is not turned on or connected well, or there may be something wrong with the modem.
(2) Line light: When ADSL is used, the modem at the customer end should establish a connection with the modem at the local end synchronously. If it can be synchronized, the line light will always be on, otherwise it will flash. If you find that the line light is flashing, it proves that the line is out of sync, which may have several reasons:
① Your telephone line is not connected correctly or has poor contact, or some telephones are not connected to the separator correctly; ② There is something wrong with the separator; ③ There is something wrong with the line.
At this time, I suggest you check whether the connection between devices is loose or falling off, and then restart the modem. If the line light is still flashing, it may be a line problem, and you need to call 10000 for repair.
(3) Network card light: indicates the connection status of modem and computer network card. If this light is off, it may be that your computer is not turned on, or the network cable connecting the network card and the modem is not connected properly, or the modem is faulty. Please make sure that the network cable is connected with the modem, network cable and network card. You can try to plug and unplug the network cable several times or replace the network cable. Another possibility is that the network card is loose or broken.
If the network card light still doesn't light up after the above steps are completed, please try a new modem, or take your modem to another place with ADSL to check if there is anything wrong with it. If the modem itself is normal, you need to seek professional help from the computer company.
