Error code 630, indicating that there is no appropriate network card or driver error cause: Hardware error, may be damaged network card or network card driver failure, or do not install network card solution: Check whether the network card is working, networking line is plugged in, reinstall the NIC driver and determine that the network card is working properly.

Error 633 problem: Dial-Up Networking network cannot connect due to device installation errors or is in use: Raspppoe not fully and correctly installed: Uninstall any PPPoE software and reinstall

Error 638 problem: After a long time, unable to connect to the ISP's ADSL access server cause: ISP server failure In the bad connection created by Raspppoe, you mistakenly entered a phone number to resolve: Run its create dial-up Raspppoe.exe check to see if the ISP service is listed to determine if the ISP is working properly, or if the phone number in the dial-up connection used is cleared or only one 0 is reserved.

Error code 645 and phone book entry not Found error reason: 1. The dial-up network adapter 3 is not installed under 2.windows98 on the Windows98 platform with more than one NIC installed. My Network Places-Properties-configuration to see if the PPPoE protocol is installed 4.windows2000 appears in "Phone book entry not found" WORKAROUND: 1. Only one network card (used to dial PPPoE instead of other network cards) on the corresponding PPPoE driver, remove the PPPoE driver on the other network card; 2. If the computer does not have a Dial-Up Networking adapter installed, you will need to install a dial-up network adapter in Windows (98 discs required), in the following directory: Control Panel-Add Add/Remove Programs-windows Setup-Communication, select all the options in this directory. 3. If the PPPoE protocol is not installed, reinstall the PPPoE protocol. "Phone book entry not found" appears in 4.windows2000 because the PPPoE software has "no" at the point of initializing the digital signature and requires the PPPoE removal to be reinstalled.

Error 650 problem: The remote computer is not responding, disconnect reason: Adslisp server failure, network card failure, abnormal shutdown caused by error resolution: Check whether the ADSL signal can be correctly synchronized, call the ISP to inquire; Check the NIC, remove all network components and reinstall the network.

Question: This refers to your computer's network device Problem resolution: Open "My Computer" → "Control Panel" → "Network connection" to see if the local connection is in the "disabled" state, if so, just double-click on the local area connection and see the status changed to "Enabled". If you don't have a local connection, you have a problem with your NIC 100%-either it's not installed or it's broken. Please contact your computer vendor, or resolve it yourself.

Error 797 problem: ADSL modem connection device did not find the reason: Adslmodem power is not turned on, the network card and Adslmodem cable problems, the software installed after the corresponding protocol is not properly state, in the establishment of a dial-up connection, established the wrong empty connection to solve: check power, The connection line; Check the network properties, Raspppoe the relevant protocol is properly installed and correctly state (related protocol), check whether the network card appears or no! number, set it to enable; Check the properties of the dial-up connection, whether the connected device uses a " Isdnchannel-adapter Name (XX) "Device, the device is an empty device, if you use cancel it and select the correct PPPoE device instead of it, or re-create a dial-up connection

Windows98, the connection cannot be established and the "prompt is connecting device" error cause: A bug that may be Windows98se is a workaround: Install WINDOWS98SE Dial-Up Networking patches.

The system prompts "Modem" to be used by another program during dialing

1, whether the modem is in a working state, such as: is sending and receiving faxes.

2, when the system starts automatically loaded the phone automatically should sign or automatically send and receive fax programs. If so, you can turn off these automatic add-ons.

3, the dialing device or other program that uses the modem terminates abnormally, the resource is not released and the computer needs to be restarted.

No terminal display issue after dialing the problem is that when the dialing setting is not selected in the properties, the "terminal window appears after dialing" is generally selected. In the dial-up Connection property, select "Terminal window after dialing" and then click "OK" button.

2, from the ADSL modem equipment can be carried out what simple fault judgment? Can be based on the display of the lights on the Adslmodem panel of the initial judgment: "Synchronous" light: Used to display the modem synchronization, solid indicates that the modem and the local side can be normal synchronization; flashing indicates that synchronization is being established, In this case, check the indoor line for quality problems or excessive telephone extension effects.

A "LAN (10m-100m)" Light that shows whether the modem is connected to the network card or hub properly. Solid means that the connection is normal, if the lamp is not bright, then the modem and the computer will not pass, you need to check the network cable, network card and modem. This lantern flashes slightly when there is data transfer in the network cable. "Power" light, power display.

Does the "Sync" light on the 3.ADSL modem not light? The "Sync" light on the ADSL modem (usually the second light) is the most important indicator of ADSL, it is the first step to determine whether ADSL can communicate. " Synchronization "Lamp has several states": "Synchronous" light if long light, indicating that the client modem and telecommunications port Modem has established a physical connection-----This is called "Synchronization", which is the first step of the normal work of ADSL, but also the most important step. Sync "If the lamp is not lit or flashing, it indicates that the modem on the client side is trying to establish a connection, that is to say, synchronous. When the user adds adslmodem to power for a few 10 seconds, the "Sync" light changes from "not lit----flashing----long", which is the process of establishing synchronization. If the "Sync" led has been flashing in the adslmodem, it means there is a strong interference on your phone line at this point, and a connector on the telephone line is not picking up, there is a loosening phenomenon or other line failure.

Solution: ①. ADSL line can not and extension, the phone can only from the splitter phone port, or it will cause the ADSL lost step.

②. The connector on the line must be connected, if the user line is iron core, you need to change to copper core wire.

③. If the telephone line is too long from the distribution box of the Telecommunication Bureau, the parallel line should be replaced with a twisted pair to improve the anti-jamming ability of the line.

④.ADSL are sometimes disturbed by weather conditions, such as heavy rains. The user can wait for a few hours to recover naturally.

4. ADSL often drop line, how to solve? Reason

① line quality is poor, line aging, outside the distance too far, too much connector, bad contact, resulting in signal attenuation too large.

②modem long time operation does not shut down, causing the modem overheating, affecting its normal work.

③ There are too many telephone extensions in the user's home, the line splitter is not installed correctly.

Solution: ① to the line rectification, outside the distance too far to change the parallel line to twisted pair and try again.

② Restart the modem, or replace the modem.

③ user telephone to connect to the extension, the ADSL line splitter must be connected to all voice equipment, that is, the line directly into the lines of the cable splitter, and then divided into two ways, the modem port to connect the telephone line to the Adslmodem;phone mouth to connect to other voice devices.

5. A phone call ADSL business will appear off the line?

Cause: ① User Line splitter installation error.

There is a complex phenomenon in the ② line. For example: the same trunk on the same time to connect the voice and signal, the same outside the installation of more than one modem.

③ Line separator failure.

Solution: The ① line splitter must be installed on the front end of all terminal devices on the line.

② only one adslmodem is reserved on the same line, all voice devices must go through the line splitter.

③ Replace the line splitter.

6. Slow Internet access (especially at night Peak)?

①ADSL technology for the quality of the telephone line, and most of the current ADSL is a RADSL (Rate adaptive ADSL), if the telecommunications company to the user between the telephone line in a paragraph there is a quality problem or by external factors interference, RADSL will dynamically adjust the user's access speed based on the quality of the line and the distance from the transmission.

②modem long time operation does not shut down, so that the modem chip overheating. Cause its performance is not normal to play, affecting the Internet speed, especially the modem automatic dialing users, may cause the modem to crash and unable to surf the internet.

Poor contact between the ③ device and the telephone line and the network cable affects the user's Internet speed.

④ user's computer operating system failure and the use of online software will also affect the user's Internet speed. Whether the network card of the user's computer is working properly, whether the driver is installed correctly, whether the TCP/IP protocol is installed correctly, whether the user installs multiple firewalls, whether to set up a proxy server, and whether to run the online anti-virus software.

There is a gap between the network requirements of the ⑤ user and the network bandwidth currently provided. Solve:

① If the user indoor line for the iron core line, too many lines, joint contact bad, the joint oxidation is serious, the noise is large, after the rectification of the line can greatly improve the speed of the Internet.

② Restart the modem, pay attention to the modem heat dissipation problem.

③ carefully check the telephone line and line separator interface is good contact, modem and the user's computer Ethernet card interface is good contact.

④ Disable unnecessary programs or firewalls and remove the proxy server settings.

⑤ at present, we provide the user with theoretical bandwidth is upstream 640Kbps, downlink 1024Kbps; its local download speed more than 70 kb/s---120 kb/s (1b=8bit) in the current situation, we provide speed can meet the user to achieve local high-speed download, access to foreign sites , VOD on Demand, online TV live, online radio, online MP3 playback, large online games, video conferencing and other local network broadband access. But for the remote VOD, legends and other large-scale games, ESPN and other online TV live, video conferencing and other broadband services, due to remote transmission bandwidth, service provider's access bandwidth, server processing capacity limits, may not reach the speed required by users, or can not connect.

7. When the broadband is installed, the computer starts very slowly and is several times slower than it normally starts. Install the network card, if not set up the IP card, the computer in the process of restarting to find a DHCP server to configure its own IP address, if found, DHCP will be selected from the address pool in the network has not been assigned IP to the request of the client. If the DHCP server is not found, the client uses the IP address and subnet mask automatically configured from the Microsoft reserved address type of 169.254.*.*, which is the subnet mask selected in 255.255.0.0. The client continues to check the DHCP server every 5 minutes in the background. If a DHCP server is subsequently discovered, the client discards its automatic configuration information and uses the address provided by the DHCP server. Otherwise, the client will continue to retry, and now everyone knows why the computer is so slow. The solution is to only set up an IP card (such as 192.168.1.2) for the NIC. In addition, some installed windowsxp Professional version of the computer will also appear to start very slow problem, even reached 1 minutes 40 seconds of many! The system seems to crash, after logging into the system, the desktop icon does not appear, the machine like stop reaction 1 minutes before normal use. This is due to the use of the Bootvis.exe program, where the Mrxsmb.dll file for the machine start added 67 seconds time! To resolve this issue, simply stop sharing folders and printers: select start → settings → network and dial-up connections, then right-click Local Area Connection and select Properties. In the window that opens, cancel the "File and Printer Sharing for Microsoft Network" check box under "This connection uses the following selected components" to restart your computer. Later, to use shared folders and printers, simply repeat the steps above, and then select the File and Printer Sharing for Microsoft Networks check box.

8. Internet often suddenly no data flow, pause for a period of time after self-recovery of normal data transmission (usually said the cut-off)

(1). Line problems

Solution: Ensure that the line connection is correct, while ensuring that the line and communication quality is not disturbed, the line connector is not bad contact, the separator is not connected to other devices that will cause line interference, such as small switchboard, crossover, anti-theft, etc., and check the line is not in contact with other wire string around. Telephones are best used with standard telephone lines, and can be used in three categories, five classes, or Super five twisted-pair lines that meet international standards. After entering the household, separate lines go. On the first line of the phone, the first walk computer. Connect the ADSL line with the cable that comes with the adslmodem.

(2). WINDOWS98 system problems

Workaround: Fix the patch. Windows patches can be found at the following URLs: Http://download.microsoft.com/download/win98SE/Update/Q243199/W98/CN/243199CHS8.EXE

(3). Network card problems, including faulty NIC or some problems with the ISA network card

WORKAROUND: The ISA NIC is best replaced with PCI, the replacement of good quality network card installation, upgrade the latest drivers.

(4). Dialing Software issues

Solution: Software are more or less always have their own advantages and disadvantages and bugs, when you use a PPPoE dialing software has a problem, you may wish to uninstall this software and swap with a different PPPoE dialing software, please be careful not to fashion multiple PPPoE software, so as not to cause conflict.

(5). System Software Setup Issues

WORKAROUND: Set the error, the longest is not set the IP address of the network card, or set the DNS server incorrectly. For ADSL virtual dial users, if the Adslmodem does not have the DHCP server function, you need to set the IP address of the ADSL network adapter. Because if the network card IP is not set, the system will check the DHCP server every few minutes to automatically assign an IP card, at the time of checking the DHCP server, some computers will be like the crash did not respond. In addition DNS to set the correct, such as Quanzhou's DNS server is: 202.101.107.55, do not set the wrong. The TCP/IP gateway that binds the ADSL network card generally does not need to be set.

(6). TCP/IP issues

WORKAROUND: TCP/IP issues are most likely to cause the inability to browse the Web page, for example, you have not changed the settings, has been able to browse, and suddenly found that browsing is not normal, you can try to remove the TCP/IP protocol and re-add TCP/IP

(7). Software issues

Workaround: Uninstall the software that is likely to cause a disconnection. It is now found that some software accidentally caused the internet interruption, under what conditions will be triggered, and further testing. When you find that opening some software is a stop phenomenon, shut down the software is normal, uninstall the software to try.

(8). Improper setup of firewalls, shared Internet software, network acceleration software, etc.

WORKAROUND: If you install a firewall, shared Internet Proxy Server software, Internet acceleration software, etc., remember not to run this kind of software to test the Internet to see if the speed is back to normal

(9). Dual NIC Conflict

Workaround: Unplug the LAN or other computer network card, only use the network card connected ADSL test, if the failure to return to normal, check two network card has no conflict

(10). Problems with modems

Workaround: Try restarting the modem.

9. ADSL sometimes does not normally surf the internet. ADSL is a technology based on twisted-pair transmission, twisted pair is two insulated copper wire with a certain regularity intertwined with each other, so as to effectively resist the external electromagnetic field interference. Most of the telephone lines are parallel lines, from the Telephone company junction box to the user phone line is mostly used parallel lines, which is very unfavorable to ADSL transmission, too long non-twisted wire transmission will cause the connection instability, ADSL lamp flashing, and thus affect the Internet. Because ADSL is in the ordinary telephone line of the low-frequency voice superimposed HF digital signal, so from the telephone company to the ADSL filter, the connection of any device will endanger the normal transmission of data, so in the filter before the phone, telephone, such as anti-theft devices.

10. ADSL synchronization is stable, but also has a drop-off phenomenon, and restart the modem can be normal. This situation occurs when there are no proxy servers, no firewalls, or network users without routers. This is because there is a "lobase-t" port on the Adslmodem, this port is the hub port of LAN. Although it is a 10mb/s port, the uplink bandwidth of ADSL is only hundreds of kb/s. If the user LAN is directly connected to the ADSL Hub,hub the following client, the network of many ADSL-independent packets will occupy the ADSL uplink channel, ADSL can not control the broadcast storm in the LAN; if the ADSL uplink transmission capacity is exceeded, the packet will be loaded into the ADSL cache If the amount of data continues to increase, the cache overflows, causing the ADSL to "hibernate" phenomenon. This is the only way to restart the modem. The solution is to do a two-card proxy server, which can be separated from the modem and local area Network direct communication, to avoid the above problems.

11. Raspppoe. EXE run Prompt no Nic selected.

①. Check if there is a network card related item in Device Manager (the system has found a network card device). If not, it may be that the NIC is not plugged in or fails.

②. Check the network card driver is correct (Device Manager in the network card item is mark or exclamation point, there is a re-installed NIC driver), the problem is still please reinstall the relevant software to try.

③.windows2000, check that the status of the local Area Connection object that is connected to ADSL is disabled and enabled.

④.windows2000 Check the network properties for each PPPoE-related item binding is selected.

12. Why is ADSL data traffic relatively large when it is easy to crash? We generally believe that this is the quality of the network card or compatibility is not good, especially the old ISA bus 10M network card, because PPPoE is a relatively new technology, this type of network card compatibility may be problematic, and slow, resulting in the collision of the final line deadlock or even panic. WORKAROUND: Replace the ISA NIC with the 10-100m adaptive NIC and update the latest driver.

13. When you play a movie, the screen is broken and choppy. Upgrade the player version and the latest drivers for the video card after you have determined that the speed can reach the movie's requirements.

14. Network connectivity but not open the page in MS-dos window ping www.sanxia.com.cn or www.sina.com.cn and other domain names, can be connected, indicating that the network is not a problem. FIX: Click the IE browser menu "Tools"-"Internet Options"-"General"-"check for newer versions of saved pages" and change "automatic" to "no check". If the webpage is still not open, you will need to reload or upgrade your browser or computer system.

15. Open Outlook on the Internet when the user can browse the Internet, open Outlook automatically disconnected, the detection found that the user set the automatic dialing function and selected "Complete send and Receive disconnect" Resolved: Remove the above two items can be normal use of Outlook. What to do: Open the outlook-menu "Tools"-"Options"-"Connect"-remove the hooks in front of "disconnect after sending and receiving". Then click "Change" to select Never dial-up connection.

16. The internet is automatically disconnected after a certain period of time. It was checked that the user selected "disconnect when idle for 20 minutes" when setting up the dialer. Workaround: Remove the "disconnect from idle 20 minutes" option to remove the error. In particular, "IE browser"-"Tools" menu-"Internet Options"-"Connections"-"Settings"-"Advanced"-"disconnect in idle 20 minutes" option remove the previous tick and make sure to exit.

17. When the information is not completed when accessing a webpage, it is no longer transmitted. When you visit a website, when you call up a homepage, the information is not passed, it stops transmitting, and the Documentdone prompt appears. Resolution: Check the modem connection status, whether it has been disconnected, if disconnected, reconnect, if not disconnected, and then refresh. The problem may be that the page you are visiting is too slow, causing a pause, and it will be better to have a different network without congestion.

18. Dial the Internet after some network software can not use the device has been connected well, can also dial the Internet, but what software is not used, including IE, Outlook, QQ. Workaround: In the Control Panel---network, if the TCP/IP protocol is more than 2, the data will not be transmitted after the Internet. Therefore, generally in the "network" only need to add the dialing network adapter, TCP/IP and other protocols. Sometimes the data transmission after the Internet is not normal because the TCP/IP protocol is compromised, it is necessary to delete the protocol and add another protocol.

19.　　How to quickly determine whether the Internet can not be caused by the wrong computer settings. Step One: Enter MS-DOS mode (Windows2000 as "command Prompt"); Step two: type: route print, a large number of numbers appear after the carriage return, If the first row of the networkdestination and netmask entries is not 0.0.0.0, then there must be a problem with the computer setup.

20.ADSL dialing shortcut keys are not available. Double-click the dial-up connection on the desktop without the Dial-up window. WORKAROUND: Reload the dial-up software after uninstalling, then create a new connection.

21. Can connect to the network, but cannot open the webpage. Dial success, QQ can also be used, but IE can't open all pages. Solution: Re-install IE try, or swap with other browsers that do not need to use the IE kernel, such as opera or Netscape.

22. Individual websites cannot be accessed. Resolution: Because the ADSL network does not have any access restrictions, so if this problem occurs, the cause of the other site.

23. PPPoE software installs and works fine, but cannot list ISP's service items? First check that the hardware connection is correct, the ISP is providing services, these can be observed by observing the Adslmodem Sync work light display status to determine if the sync work lights display normal work, then check the computer other devices interfere with the work of ADSL, and upgrade their drivers, We came across a sound card. The old version driver causes the PPPoE software to not list the service items correctly. Also need to pay attention to is whether the ISP has opened your service, because ADSL also has some special number bundled in the telephone switch, the ISP needs to certify these numbers only to think your line is legally available, also has the ISP's ADSL access server not open, then you also cannot list the server project.

24. Why is my PPPoE software not properly installed? In general, to check from the following aspects, the driver of the network card is installed correctly, before the installation of other PPPoE software uninstall clean, the system is installed with other network software such as shared Internet software, if there is a best uninstall, PPPoE installation after installing them, For WinPoET (Raspppoe) It is also necessary to check whether the operating system Dial-Up Networking components are installed correctly.

25. After the Windows2000 installation protocol is complete, no related items are found in the network properties when the PPPoE protocol software is not installed in the network properties for PPPoE related items. FIX: Right-click My Computer-Properties-hardware-digital signatures to close the Prohibit unsigned driver files item.

26. I have entered the account number and password, why the prompt password is incorrect?

The correct format for the user name is: [[email Protected]][email protected][/email] (ADSL user) or [[email protected]][email protected][/email] (LAN user).

If you are prompted with a bad password, there are two possibilities:

① your account is being used by someone else.

② The password you entered is wrong, please dial 10000 to reset the password.

27. Why does the first dial-up fail after Winpoe boot? Analysis of the Windows operating system should be a problem, the boot will not fully drive the WinPoET PPPoE driver, can not complete the dial-up, there is also a situation is WinPoET error will also cause the first dial failure, it is estimated that the drive management is compromised, Reinstalling Windows and WinPoET will generally solve the problem.

28. Why installed ADSL and Enternet300 after the Web page especially slow? This is due to the Internet Connection Wizard of Windows to specify the access Internet interface error caused by IE, Enternet300 using the Local area network type virtual dial, and IE default to use normal dialing, when browsing the first time IE look for dial-up interface, Can not find the dial after the LAN there is no proxy server, finally will find Enternet300 this interface, so it will be very slow. WORKAROUND: Only need to rerun the Internet Connection Wizard, select the Local area network mode, and cancel the automatic search proxy server can be resolved.

ADSL (China Telecom \ Telecom) Common fault codes ...
