whether the problem is resolved. If the problem persists, continue until the fault disappears. Layered Network diagnosis technology Physical Layer faults mainly occur when the physical connection mode of the device is correct, the connection cable is correct, and the configurations and operations of devices such as Modem, CSU, and DSU are correct. The best way to determine whether the physical connection of a vro port is intact is to use the show int

Early domestic ADSL line access are bridge mode, by ADSL modem and computer, in the computer to allocate fixed IP address, boot can access to the local terminal equipment into the Internet. However, when the user does not boot on the Internet, IP is not to be exploited, will cause the current increasingly scarce public network IP resources waste, so there has been a PPPoE dial-up ADSL access. PPPoE dial-up can enable the user on the power-on dial-up

In the use of ADSL sharing dial-up networking environment, there are often inexplicably download interrupt phenomenon, the Web page can not open the phenomenon or the phenomenon of online multimedia streaming suddenly interrupted, and so on, these phenomena are believed that most users who use broadband dial-up often encounter. However, when these phenomena occur to the ADSL modem for careful examination, we will see the dial-up login is in a success

dial-up Internet access To facilitate the management and maintenance of the ADSL Modem device during Internet access in the future, many manufacturers often set the "80" port of the ADSL Modem device to its backend Management port, however, if an attacker or hacker knows the default IP address of the ADSL Modem, the administrator password of the ADSL device may

ADSL is a very common broadband access method. However, since one user has only one ADSL account, how can we achieve multi-user sharing of ADSL? Here we will introduce the implementation method. ADSL is an affordable broadband access solution. Currently, it is billed on a monthly basis. if a user uses an account to access the Internet, it will be a bit uneconomical. How can one ADSL user access the Internet? The following are some experiences. Sharing principle: in view of the current mainstream

There are a variety of wireless Internet access methods. We often see wireless network interfaces and wireless network interfaces for wireless Internet access. For today's wireless trends, the wireless access of infrared seems a little retro. It cannot be said that it has been out of the stage, at least in terms of choice, it has gradually been forgotten by everyone. Next we will introduce a wireless Internet access solution through infrared rays. This method is based on GPRS traffic to access t

routers on this side of the WAN port are plugged in, but not connected to the modem, LAN access is not connected to the wall modules. 2, network cable connectivity failure, mainly the quality of the network cable is poor, or the line sequence is not correct. Modem access to the router, usually the modem distance from the router is not far, as long as the line s

ADSL is an affordable broadband access solution. Currently, it is billed in monthly subscription mode. If a user uses an account to access the Internet, it will be a bit uneconomical. How can one ADSL user access the Internet? The following are some experiences.　　 Sharing principle　　 In view of the current mainstream Ethernet interfaces, the external ADSL Modem has built-in routers and routing functions, and also has a large-capacity ROM chip (includi

At present, ADSL permeate every corner of our lives, whether it is enterprises, Internet cafes, or home users using ADSL to access the Internet, usually, an ADSL line can only support one computer to access the Internet, however, after using a networking device, you can implement an ADSL line to support Internet access shared by multiple computers. Generally, devices that implement the shared networking of ADSL include ADSL Modem, Broadband Router, an

wireless router, we have to do the physical connection operations related to the wireless router: First of all, the ADSL modem device is connected to the WAN port of the wireless router, and then the common twisted pair connects the LAN port of the wireless router with the normal workstation. After completing the physical connection operation, we go to the Windows system interface of the normal workstation and open the system's TCP/IP property Setti

Shanghai Bell Company's Cablelink Cable modem system provides high-speed asymmetric data communication services to users through the fiber coaxial hybrid network. The asymmetry of its connections requires high-speed communications in one direction, such as network browsing, Internet file transfer, and ideally in the opposite direction with a lower-rate delivery service. The TDMA access method used in Cablelink 2000 system can make the system more flex

1.ADSL modem or NIC Setup problem Modem generally has 2 modes of operation, one is the normal mode of using dial-up software, one is the routing mode of automatic dialing. In normal mode, you do not need to set up your modem, use the default. While the routing mode needs to be set up, modem with its own flash memory,

ADSL can provide users with more than 6Mbps of data transmission bandwidth, this condition is enough to achieve Internet access, video on demand and access to the local area network. ADSL can achieve bidirectional transmission rate of 640 Kbps in interactive mode. ADSL technology has increased the bandwidth of the existing public telephone network data transmission 50 times times. The transmission of voice, text, and low-resolution images is no longer limited by bandwidth. ADSL technology can b

China's broadband routers are developing very fast and their technology is also very mature. Many people may not know the application of broadband routers in the access technology. It doesn't matter. After reading this article, you will certainly have a lot of GAINS, I hope this article will teach you more things. At present, ADSL permeate every corner of our lives, whether it is enterprises, Internet cafes, or home users using ADSL to access the Internet, usually, an ADSL line can only support
