◆ During dialing, the system prompts "Modem" to be used by another program 1, and whether the modem works, such as sending and receiving faxes. 2. When the system is started, whether the automatic telephone answering symbol or the program for automatically sending and receiving faxes is automatically loaded. If so, you can turn off these automatic add-ins. 3. The dial-up program or other programs using the modem terminated abnormally and the resources were not released, so it is necessary to restart the computer.
◆ There is no terminal display after dialing. The problem lies in the dialing settings. In the properties, "Terminal window appears after dialing" is not selected. You can generally choose. In the dial-up connection properties, select "Terminal window appears after dialing", and then click OK. 2. What simple faults can be judged from ADSLMODEM equipment?
According to the display of the signal lamp on the ADSLModem panel, we can make a preliminary judgment on the problem: the "synchronization" lamp is used to display the synchronization of the modem, and the constant light indicates that the modem and the local terminal can synchronize normally; Blinking indicates that synchronization is being established. At this time, check whether there are quality problems in indoor lines or too many telephone extensions. "LAN( 10M— 100M)" light is used to show whether the connection between modem and network card or hub is normal. Always on indicates that the connection is normal; If this light is off, there must be no connection between the modem and the computer. There are network cables, network cards and modems that need to be checked. When there is data transmission in the network cable, this light will blink slightly. "Power" light, power display.
The "synchronization" light on the third floor is on. ADSLModem is not on?
The "synchronization" light (usually the second light) on ADSLModem is the most important indicator light of ADSL, and it is the first step to judge whether ADSL can communicate. The "synchronization" light has several states: If the "synchronization" light is on all the time, it means that the modem of the client has established a physical connection with the modem of the telecommunication bureau. It is also the most important step. If the "synchronization" light goes out or flashes, it means that the modem of the client is trying to establish a connection with the modem of the telecommunication bureau, that is, synchronization is in progress. When the user energizes the ADSLMODEM for dozens of seconds, the "synchronization" light will change from "off-flashing-on" to "on". A connector on the telephone line is not connected correctly, and there is looseness or other line fault. Solution: ①. ADSL lines cannot be extended in parallel, and the telephone can only be led out from the telephone port of the separator, otherwise ADSL will be out of step. (2). The connector on the line must be connected. If the subscriber line is iron core, it needs to be replaced with copper core. ③ The telephone line from the junction box of the telecommunication bureau is too long, so twisted pair should be used instead of parallel lines to improve the anti-interference ability of the line.
4.ADSL is often dropped, how to solve it?
Reasons ① Poor line quality, aging of the line, too long external distance, too many connectors and poor contact of the connectors, resulting in excessive signal attenuation. (2) The modem is not turned off after working for a long time, which leads to overheating of the modem and affects its normal work. (3) There are too many telephone extensions in the user's home, and the distributor is not installed correctly. Solution: ① Rectify the line. If the distance of the outside line is too long, you should change the parallel line into twisted pair and try again. ② Restart the modem or replace it. (3) If the user wants to connect the extension, it must first connect the ADSL splitter, and then connect all voice equipment, that is, the external line is directly connected to the line port of the splitter, and then divided into two roads, and the telephone line connected to the Modem port is connected to the adslModem；; The telephone line connected from the telephone port is connected to other voice devices.
5. Is 5.ADSL service dropped as soon as you make a call?
Cause: ① The subscriber line separator is installed incorrectly. ② The lines are reconnected. For example, voice and signal are simultaneously multiplexed on the same trunk line, and multiple modems are installed on the same external line. ③ Fault of line separator. Solution: ① The line separator must be installed at the front end of all terminal equipment on the line. ② Only one adslModem is reserved on the same line, and all voice equipment must go through the line separator. ③ Replace the line separator. 6. Slow Internet access (especially in the evening rush hour)?
(1) ADSL technology requires high quality of telephone lines, and most of the ADSL currently used is a RADSL (Rate Adaptive ADSL). If a telephone line between a telecom company and users has quality problems or is interfered by external factors, RADSL will dynamically adjust the access speed of users according to the line quality and transmission distance. (2) The modem is not turned off for a long time, which makes the modem chip overheat. As a result, its performance can't be played normally, which affects the internet speed, especially for users who use the modem to dial automatically, which may cause the modem to crash and unable to access the internet. (3) Poor contact between the equipment and telephone lines and network cables will affect the speed of users surfing the Internet. ④ The failure of the user's computer operating system and the use of internet software will also affect the user's internet access speed. Whether the network card of the user's computer runs normally, whether its driver is installed correctly, and whether the TCP/IP protocol is installed correctly; Do users install multiple firewalls, set up proxy servers and run online antivirus software at the same time? ⑤ There is a gap between the network demand of users and the network bandwidth currently provided. Solution: ① If the user's indoor line is iron core line, there are too many line connectors, poor contact of the connectors, serious oxidation of the connectors and high noise, the internet access speed can be greatly improved after the line is rectified. ② Restart the modem and pay attention to the heat dissipation of the modem. ③ Carefully check whether the interface between the telephone line and the distributor is in good contact, and whether the interface between the MODEM of the user's computer and the Ethernet card is in good contact. ④ Close unnecessary programs or firewalls and delete proxy settings. ⑤ At present, the theoretical bandwidth we provide to users is 640Kbps upstream and1024 kbps downstream; The local download speed is over 70 kb/s-120 kb/s (1b = 8bit). As far as the current situation is concerned, the speed we provide can satisfy users' local high-speed download, access to foreign websites, VOD on demand, live online TV, online radio stations, online MP3 players, large-scale online games, video conferences and other broadband access to local networks. However, for large-scale games such as remote VOD and Legend, and broadband services such as Internet TV live broadcast and video conference such as ESPN, users may not be able to reach the required speed or connection due to the limitations of remote transmission bandwidth, access bandwidth of service providers and processing capacity of servers.
7. After installing broadband, the computer starts very slowly, which is several times slower than usual.
Install the network card. If the IP of the network card is not set, the computer should look for a DHCP server to configure its own IP address during the restart process. If found, DHCP will select an IP from the address pool that has not been assigned to the requesting client in the network. If the DHCP server cannot be found, the client will automatically configure its IP address and subnet mask with the address selected from Microsoft reserved address type 169.254. *. * The subnet mask is 255.255.0.0. The client continues to check the DHCP server every 5 minutes in the background. If the DHCP server is subsequently discovered, the client will give up its automatic configuration information and use the address provided by the DHCP server. Otherwise, customers will keep trying. Now everyone knows why the computer is so slow. The solution is just to set an IP for the network card (for example, 192. 168.438+0.2). In addition, some computers with WindowsXP Professional Edition will start very slowly, even reaching 1 min for 40 seconds! The system seems to have crashed. After logging into the system, the desktop icon does not appear, and the machine image stops responding 1 minute before it can be used normally. This is due to the use of the Bootvis.exe program, in which the mrxsmb.dll file adds 67 seconds to the machine startup! To solve this problem, just stop enjoying folders and printers: select Start → Settings → Network and Dial-up Connections, right-click Local Area Connection and select Properties. In the window that opens, uncheck the check box "Files and printers on Microsoft network * * *" under "This connection uses the following selected components", and then restart your computer. In the future, to enjoy folders and printers with * * *, just repeat the above steps, and then select the * * * Enjoy files and printers on Microsoft networks check box.
