The following content from: http://www.aikko.com/bbs/viewthread.php? Tid = 13417 extra = page % 3D1 With the popularity of ADSL, people enjoy the speed of broadband, and network security has been paid more and more attention. Have you ever thought that your ADSL account and password are actually exposed on the Internet? Using some tools and techniques, you can easily obtain your account and password to access the Internet, and even purchase products such as QQ coins, lianzhong monthly card, and

problem is resolved. If the problem persists, continue until the fault disappears.Layered Network diagnosis technologyPhysical 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 interface command

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

The internet will often encounter a drop in the line. The Web page can not open, download interrupted, or online video, audio streaming interruption, QQ off the line, the game out of line phenomenon. We might as well assume that the landlord is using ADSL Internet. In fact, other ways of surfing the internet often dropped the reason and the following reasons are roughly the same. Now let's analyze the reason for ADSL off line. 3lian Material One, line problem first check the home line, to se

Failure phenomenon: XP system, the normal dialing, IP address has been allocated, but is not online, QQ, browsing the web is not good, reload the cat's drive, with the dial-up software is not, the cat line and power indicators are bright, not hot, restart the computer and cat useless, can ping with their own IP, recently appeared many times, Strange is how not to do , no matter how well he's done for a while, ask for help. Solution: 1. Prompted that the search page could not be opened. This t

Troubleshooting Router Interface Serial Port Trouble Shooting Serial port connectivity problems, in order to eliminate the serial port fault, usually from show interface serial command, analysis of its screen output report content, to find out where the problem lies. The beginning of the serial port report provides the state of the interface and the status of the line protocol. There are several possible combinations of interfaces and line protocols: 1. Serial port operation, line protocol ope

digital signal into an analog signal, and the receiver uses the demodulator to convert the received analog signal into a digital signal, which is the modulation and demodulation of the signal.The device that implements the modulation and demodulation tasks is called a modem. When using the frequency band transmission, each side of the communication is connected to a modem, and the digital signal is sent to

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

is a dual-CPU architecture, as shown in figure 1. The main processor runs an open operating system and controls the entire system from the DBB (Digital Baseband Chip) where the processor is a wireless modem ), it mainly implements A/D conversion of voice signals, D/A conversion, encoding and decoding of digital voice signals, channel encoding and decoding, and timing control of wireless modem.

ADSL is today a relatively affordable broadband access scheme, its billing is currently generally used in the way of the monthly. If a user uses an account to surf the internet, it is bound to be a bit not cost-effective, how to achieve an ADSL multiple users online? The following is an exchange of experience. Sharing principle In view of the current market mainstream Ethernet interface External ADSL modem has a built-in router, with routing functions

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

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

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
