In fact, the installation of the ADSL Router is quite simple, because we have daily contact. Therefore, you have not paid too much attention to the installation details of the ADSL Router. Regarding network settings, how do I set up a total of ADSL Modem, routers, and switches ...? Connect and configure the vro and adsl Modem to the Internet !? ADSL Network disconnection problems-

When using ADSL to access the Internet, you may often encounter problems such as webpage disconnection, download interruption, online video, audio stream interruption, qq disconnection, and game disconnection. We may assume that the landlord uses ADSL to access the Internet. In fact, the reasons for frequent disconnection from the Internet in other ways are roughly the same as those below. Next we will analyze the causes of ADSL disconnection.
I. Line Problems
First, check the home line to see
Due to the use of Internet broadband connections, the dial-up modem is outdated, but there are still some situations that require dial-up access. a ppp server in the Office provides another method for users to access email and Internet when they are on a business trip. when a server or network problem occurs, the dial-up modem also provides an emergency connection for the system administrator. the following
The functions of the ADSL Broadband Router are very powerful, and its performance is also very good. Next we will mainly explain how the ADSL Broadband Router achieves Internet sharing among multiple computers. 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
With the popularization and application of computers, computer functions become more and more powerful and hardware devices become more and more powerful to meet people's needs, such as ISA, PCI sound card, modem, USB hard drive, mouse, and so on, and a variety of brands. So how should we use and set these devices in DOS?
In fact, many hardware devices do not need to install any drivers in DOS.Program, As long as the hardware or BIOS is set up, such
. The difference is that the LRP configuration method is relatively primitive, each step requires a command line or a configuration file to be modified. freesco provides an interactive menu wizard configuration program, making it easier to operate.Currently, the latest version of freesco is 0.3.2, based on the Linux 2.0.38 kernel. Available on the software Homepage.System RequirementsThe computer used as a router needs to have a CPU of more than 386, 8 MB of memory, a soft drive, a NIC connected
has a built-in modem for the ESS, will that be the problem? So the author in the resource manager carefully checked the built-in modem, did not find a yellow exclamation mark, However, when the author chose to "View the device by connection", and then click "Computer" to show all IRQ interrupts, but found that the original ESS built-in modem and USB devices are
Most of ADSL hardware faults are caused by connection looseness, network cable disconnection, Hub damage, and computer system faults. Generally, you can locate the problem by observing the indicator. In addition, the voltage is abnormal, the temperature is too high, and lightning strikes are also prone to faults. If the voltage is unstable, it is best to provide small-Power UPS for the equipment. The MODEM should be dry and ventilated to avoid water f

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.

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.
