network failure, so when the fault encountered, nature will be suspicious of the eyes turned to the virus program or Trojan program. The virus causes ADSL to drop the line In order to check whether there is a virus in the workstation, the author immediately hands-on to find the latest version of the anti-virus software, and the workstation of each "corner" of a thorough virus killing operation, after a long time after the antivirus wait, the author from the workstation system has really found

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. Master-slav

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

1. Shared Internet access (1) network connection If you want to add an additional computer to share the Internet with ADSL, You need to purchase two more NICs, one installed on the Internet access computer, the other is installed on the computer to be shared (hereinafter referred to as the client. We recommend that you purchase a 10/100 Mbps white adaptive Nic. It is worth mentioning that if the ADSL modem is an external Ethernet interface, there will

Now there are more and more users using the ADSL Broadband Network, and the maintenance of the ADSL equipment has become a problem that cannot be ignored. Only by maintaining it well can you not only save your "Broadband Journey", but also prolong your life. Routine Maintenance The necessary routine maintenance for ADSL equipment can not only reduce unexpected faults, but also ensure smooth network and improve the service life of the equipment. The main routine maintenance includes the following

Asyuncrical Digital Subscriber Loop Asymmetric Digital user line Loop (ADSL) is a member of the xDSL family and is hailed as "express on modern information highway" by Western countries ". Because of its high downlink speed, high frequency bandwidth, and excellent performance, it is favored by many users and has become another new and faster and more efficient access method after MODEM and ISDN, it is also the most widely used access method in China.

, especially the latter. They have different transmission features, market positioning, physical location, and problems to be solved, in the future, many technologies may coexist in actual access networks. This article will introduce some major Wired Broadband Access Technologies. At present, the main wired broadband access technologies include: ordinary Modem, N-ISDN narrowband integrated business Digital Network), Cable

used to debug the kernel running on the target computer. For better performance, you can use a well configured computer as your development computer. 0 Modem cable (Null modem cable) A 0 modem (Null modem) is a means of communication using a RS-232 serial cable to connect two computers. The original RS-232 standard

hard disk devices in this computer is not a conflict of the problem, then where is the problem? So the author again installed the flash drive driver, The problem is still unresolved.The author once used in some old machine on this flash drive, can be used normally, in this machine should also have no problem. So I think there may be a problem with the flash drive, in order to verify the flash drive, the author will be inserted into the latest computer flash drive, the results of the flash drive

Recently too busy, there is no time to write about the ucos-ii transplant, first of all the work is easy to make a mistake in the knowledge points recorded, about the CTS and RTS. In RS232 the CTS and RTS have a clear meaning, but since Hayes (HAYES) introduced smart Cat (SmartModem) is a bit confusing, but now this meaning for the mainstream, the main chip manufacturers of the UART controller flow control basic use HAYES Modem flow control interpreta
