FCC (Communications Commission full name of the U.S. Federal Communications Commission) July 24, 2010 for the word "broadband" a definition, the FCC that broadband means that the download rate of 4Mbps, At present, a wide variety of broadband in China is the telecommunications sector ADSL access (via telephone lines), broadband network company's LAN access (through the broadband Company's fiber network) and radio and television cable Modem (through the CCTV line) access. To achieve broadband ac

Now the development of the function needs to jump directly to the dial-up, contact, SMS interface and so on, looking for a lot of information, I organized a bit. 1, jump to the Dial-up interface, the code is as follows: 1) Direct dialing Intent Intentphone = new Intent (Intent.action_call, Uri.parse ("Tel:" + phonenumber)); StartActivity (Intentphone); 2) jump to the

Broadband Router Setup method: If you buy a broadband router price is relatively cheap or buy the time is relatively early, then he is relatively low-end in function. We can only achieve his automatic connection network functions, other advanced features can not be achieved, the specific methods are as follows. The first step: through the broadband router's management address to connect, enter the correct username and password into its management interface. The second step: the author's broa

Open the Ubuntu application-system tool-terminal to open a terminal, enter the command: sudopppoeconf, and then proceed. Enter the adsl user name and password in the middle. In the future, you need to manually dial, open the terminal, and enter the command: sudopondsl-provider. In general, after one dial, the system will automatically dial the Internet after logg

In the RIP routing protocol, slow convergence is a special feature. What slow convergence? Here we will introduce it in detail. In addition, we will explain how to use the RIP routing protocol for dial-up networks. I hope the summary in this article will be helpful for your learning. Slow convergence Split horizon update can be used to solve the slow convergence problem. when the range separation technology is used, the router records the interfaces t

Originally in Ubuntu 15.10 with dial-up Internet no problem, but upgraded 16.04 LTS found the original DSL connection is not on. The main performance is:1, in NetworkManager the choice DSL connection can try to dial the connection, even after two or three seconds on the broken;2, after many times in accordance with the online method to modify the strange configuration, ultimately not even at all;3, delete t

How to set up automatic dial-up Internet access is a common user to use a broadband network account to achieve multiple computers together to access the most commonly used method, then how to build a shared Internet environment? Let's take a look at the details below. Set up their own share of the Internet after the problem is also followed, users want to achieve each start of the computer can automatically connect the function of the network, rather

For wireless data networks, voice is a "killer application ". The high-performance Wi-Fi mesh network system is a killer IP wireless network. However, not all mesh networks are identical. As wireless mesh networks become increasingly popular-almost every day, people announce the newly deployed public and private networks. To add voice applications to business needs, the network needs to improve overall perf

1 Introduction In recent years, with the rapid development of Internet and Intranet, the demand for high-speed user lines with fixed connections has become increasingly urgent. xDSL technology based on twisted pair wires is emerging because it achieves high-speed user lines at a low cost, this breaks the situation where high-speed communication is exclusively controlled by optical fibers. Adslasyuncrical Digital Subscriber Line, asymmetric Digital user Ring Line) uses a pair of telephone lines t
