communication protocol operation. The MAC address is expressed in three bits, that is, eight devices can be addressable in one micro-network (the number of connected devices is actually unlimited, but only eight devices can be activated at the same time, one of them is primary, and seven are slave ). Figure 1 shows the topology of a Master/Slave Device in the micro-network. In addition, the Bluetooth system supports point-to-point communication to form a distributed network, that is, one master

Analysis of the problem: Why is the ADSL connection disconnected? Web pages cannot be opened, downloads are interrupted, or online video and audio streams are interrupted. These problems may cause many users to access the Internet through ADSL. However, when you carefully check the status of the adsl modem, you will find that the dial-up login is successful. So what exactly is the problem? How Should ADSL users troubleshoot? ADSL Network disconnection

save investment; it can enjoy ultra-high-speed network services to provide users with asymmetric upstream and downstream transmission bandwidth; it saves costs, you can call the Internet at the same time without affecting each other, and you do not need to pay additional phone fees when accessing the internet. The installation is simple, and you do not need to apply for additional lines. You only need to install an ADSL Modem on a common telephone li

Cause of failure This problem may occur if one of the following conditions is true: • Line noise is present on the telephone line connected to the modem. • The modem appears to behave abnormally. • A timing problem occurs between the computer and the modem. Warning: If you modify the registry incorrectly by using Registry Editor or other methods, you may have

At present, wireless router has become a home wireless sharing and Internet application of the mainstream, about the use of wireless router is also a lot of users are very interested in, we will pick some of the more representative of the wireless router problem, for you one by one to explain its fault solution, I hope you can analogy. The wireless router's red diagnostic or power light has been flashing. Wireless router does not work properly, how to solve? A: This is generally because the wi

Preface You can use the test TCP Program (TTCP) to measure the TCP throughput through the IP path. Use it to start the receiver at one end of the path, and then start the transmitter on the other side. The transmitting end sends the specified number of the TCP information package to the receiving end. At the end of the test, both parties display the number of transmitted bytes and the time passes so that the information package can consume data from one end to the other. You can then use these g

Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. Chapter 7 serial line IP The serial line protocol SLIP and PPP provide Internet connections for those who lack funds. In addition to a modem and a FI In addition to the serial board (card) of the FO buffer, other

What is the difference between broadband and ADSL Internet access? With the explosive development of the Internet, commercial applications and multimedia services on the Internet have also been rapidly promoted. To enjoy various services on the Internet, users must access the network in some way. Fiber-to-user FTTH is an inevitable direction for the development of the user's network in order to achieve digital and broadband access for users and improve the user's Internet access speed. However,

completely different. There is an ISDN signal in the line. When the telephone and data are together, the ISDN must change the number, which is also a small advantage of ADSL.Can I use a dial-up Modem as an ADSL Modem?A: No. The ADSL Modem is different from the current dial-up Modem. The modulation method and network s

Enter sudo gedit/etc/ppp/options on the terminal and change lcp-echo-failure 4 in the pop-up document to lcp-echo-failure 40. This is because Ubutnu's default settings have obvious defects, lcp-echofailure is set to 4, and lcp-echo-interval is set to 30 seconds. That is to say, if no echo-reply signal is returned when the ADSL dial-up Internet access server is configured within 120 seconds, Ubu
