Analysis and treatment of four kinds of ADSL faults

In the use of ADSL, we often encounter a number of fault problems. Many of the questions look very "weird" and many friends don't know how to solve them. Here we summed up a few ADSL fault situation, to help you analyze and solve. ADSL fault 1.ADSL Modem "Sync" light does not light? ADSL Modem on the "Sync" light (usually the second lamp) is the most important ADSL, it is the first step to determine whe

Configuration of Internet shared access using the ADSL routing function

There are two common ways of Internet access through ADSL: server sharing and router sharing. If you don't want to waste a computer as a server, you can check whether your ADSL Modem has the routing function (the instructions are provided ), if the ADSL Modem with the routing function is used, the Modem itself can be used as a host. Let's take a look at the speci

Principles for Network Fault Diagnosis [transferred from www.cnitblog.com/wildon]

Diagnosis Technology 1. the physical layer and its diagnostic physical layer are the most basic layers in the OSI layered structure system. Based on the communication media, the physical interfaces of the system and the communication media are implemented to transparently transmit data link entities, provides services to establish, maintain, and remove physical connections between computers and networks. Physical Layer faults mainly occur when the physical connection mode of the device is corre

In fact, in addition to having a certain relationship with the customer's line quality, the stability and compatibility of the ADSL Broadband Modem are also a critical issue. To improve the performance of ADSL Internet access, You must select a broadband Modem with superior performance. The rea
