In enterprises, the function of a wireless LAN switch is very powerful. For more information about the function of the switch in the network, see "network traffic police"-a wireless LAN switch.) here, let's take a look at how to use a wireless LAN switch to Efficiently build

Q: How to solve the network neighbor access response "slow" in the LAN? A: Did you come across this de situation? In Windows98 and Windows95 peer-to-peer networks, access to other computers through the network Neighborhood can sometimes be refreshed several times to connect. Access to other computers in Windows Server or Win dows Advanced server, especially wh

Get rid of irrelevant options In Windows XP, double-click Folder Options in Control Panel, click the View tab, and then scroll the mouse pointer to the bottom of the window to see an "Auto Search for network folders and printers" item that is selected by default and removes it. In this way, when we print, Windows XP does not take the liberty of looking for printers on the LAN and installing drivers to p

Java Network Programming and simple chat programs Network Programming technology is one of the mainstream programming technologies in Internet technology. It is necessary to understand some basic operations. This chapter mainly describes network programming, UDP and Socket programming, and a simple

This is the last part of the IP network design series. This article will discuss some problems encountered in the design of campus LAN. The advantages of Ethernet switches over the traditional hub environment will be described first. The motivation for applying a virtual LAN has been studied together with the problems encountered in planning and configuring a vir

I. Common LAN Topologies 　 Computers and other devices in the network need to be connected in a certain structure. This connection method is called "topological structure ", in general, how are these network devices connected together. Currently, the following network topologies are common: 1) Star Structure 2) Ring S

Detailed explanation of network interconnection devices used for LAN construction computer networks are often made up of many different types of network interconnection connections. If several computer networks are physically connected together and cannot communicate with each other, then this "interconnection" is meaningless. Therefore, when talking about "inter

In large-scale LAN networks, network channels are often severely congested. There are many causes of this fault, such as virus attacks on the network, hardware damage on the network device, and transmission bottleneck on the network port. However, according to the statistica

Authentication-password control We recommend using password control on wireless network sites-of course, it is not necessary to be confined to wireless networks. Network operating systems and servers such as Novell NetWare and Microsoft NT provide built-in multi-level security services, including password management. The password should be under strict control and should be changed frequently. Wireless
