The popularity of broadband has greatly changed our network life and made it more colorful. However, the various faults and problems that followed have made it impossible for many netizens who first came into contact with broadband. The failure of the broadband network is very different from that of the conventional Modem. This article takes the city of Shanghai where the author is located as an example to describe various common faults. Line Fault Th

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

Broadband routers in China are developing very rapidly. Here we mainly introduce the access to ADSL Modem with routing functions, including the access to ADSL Modem + Broadband Router. 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, howe

difficulty in understanding SRP is in the case of a multifunctional class, which is not easy to understand the contradiction between versatility and single change. Let's take a look at a modem class example, modem has 4 functions: dial-up, hang up, send data, receive data: class　Modem　{ 　　　　 public　void　Dial(string　aPno)　{…} 　　　　 public　void　Hangup()　{…} 　　　　 p

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

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
