Currently, home users' broadband access can be achieved through ADSL, LAN, HFCs, and PLC. Due to network restrictions, any broadband access service provider can only provide one or two access methods for users. In practice, these solutions vary in terms of network access methods, user costs, and service content that can be provided. When selecting a broadband access service provider, you must first consider which access method is more suitable for you

places such as the conference room. In this case, we should note that wired network interfaces must be provided to facilitate the implementation of these special applications. 3. For enterprises with both wireless and wired networks, it is best to adopt different IP address management policies for security and management convenience. We all know that IP address management policies are the most fundamental content of Enterprise LAN Management. Not onl

services. The CSMA/CD media access control method is still used. All nodes connected to a hub share a conflict domain.You can listen for packets in the link by stringing a hub in the network link. Multiple nodes connected to a hub cannot send data frames at the same time, and can accept data frames simultaneously.Hub in English is called "hub", that is, the meaning of "center", the main function of the hub is to connect the received signal to re-shap

connect to the corporate network using 802.1X authorization and auditing. If used with server authentication, 802.1X can also prevent users from accidentally entering the fake honeypot ap. Finally, it is necessary to perform wireless network data protection and access control options. Central Wireless LAN administrators can help reduce the error configuration of AP and speed up the system recovery after a

table ). 5. publicarp In publicarp mode, ettercap uses ARP spoofing to listen for the communication (Half Duplex) between a host on the Internet and all other hosts ). This method sends ARP responses in broadcast mode, but if ettercap already has a complete host address table (or the host on the LAN has been scanned when ettercap is started ), ettercap automatically selects the smartarp method and sends the ARP response to all hosts outside the m

The wireless local area network (WLAN) industry is one of the fastest growing industries in the whole data communication field at present. Because of its flexibility, mobility and low cost of investment, wireless LAN solution, as a supplement and extension of traditional wired local area network, has gained the favor of home network users, small and medium-sized office users, vast enterprise users and telecom operators, and has been applied rapidly. H

Check the NIC first when there is a problem In the LAN, the phenomenon of the network is often occurring, once encountered such a problem, we should first carefully check the network of the machine, network card settings are normal. When checking, we can open the Control Panel/System/device Management/Network adapter Setup window in turn by using the mouse. Check for interrupts and I/O address conflicts in this window (it is better to set the interrup

In the LAN dual-route settings of universal routing, we assume a LAN environment. Two universal routers are connected to six computers and use ADSL to dial the number. The setting method is as follows:1. First, set a vro to be able to access the Internet normally. Everyone may have already set it, so there will not be much to worry about here.2. Set the IP addres

address, then we need to manually allocate resources. For example, some early NICs used the interrupt address "3", which may conflict with the com2 serial port. If your com2 serial port is idle, you can disable the com2 serial port in "communication port → properties" (as shown in 1), or set "onboard UART port" to "Disable" in BIOS settings, in this way, the interrupt address "3" is used by the NIC. Some PCI NICs use the interrupt address "10", which conflicts with some graphics cards. You can

test must note all modules in use in the system. Even LAN switches with stackable switches or fixed ports may only use certain modules, which may potentially affect power consumption. In general, this option includes the uplink port and the stacked port used to connect a vswitch baseboard to another vswitch baseboard. 3. Influence of Power Supply For a system that provides multiple power supplies, when the

called multicast communication. The use of multicast communication technology can not only realize the function of communication between a sender and multiple receivers, but also can effectively reduce the burden of network communication and avoid the unnecessary waste of resources.Broadcast is also a mode of implementing a one-to-many data communication, but the broadcast and multicast are different in implementation mode. Broadcasting is the sending of data from a workstation, and all other w

Each layer of communication has its own unique security problems. Communication connections at the second protocol layer of the data link layer are relatively weak in terms of security. Network security issues should be addressed at multiple protocol layers for different vulnerabilities. In this article, we will focus on security issues related to wired LAN.In the communication at the second protocol layer, vswitches are key components and are also used for communication at the third protocol la

the number of access requests increases, the stability of wireless access will become a problem. However, there are more AP scenarios, at this time, the signal interference caused by multiple APS is difficult to control. Once the terminal moves from one location to another, switching between networks under the jurisdiction of each AP requires disconnecting, re-selecting, and connecting steps, which naturally interrupts the network applications at that time. Of course, it may be just a few dozen

Many companies use wireless networks to ensure easy and error-free communication between employees. Therefore, fault locating and troubleshooting in LAN is more important than ever. In the current business field, many meetings are conducted through the network rather than in the office. Maintaining the security and reliability of LAN is essential for companies of different types and sizes. The three most co

line distance of about 60 meters. The connection cannot be established when the window is closed, however, you can move the network adapter and AP to the window and open the window to establish a connection, but the data transmission is not stable. How can this problem be solved. Cause and solution: To make the transmission distance longer or enhance the transmit power, you can purchase a separate antenna. Otherwise, the signal transmission speed and stability of wireless products are greatly a

, resulting in a serious "Fever" of the core switch, which eventually leads to a slow Login Server failure. This factor rarely occurs, during the troubleshooting process, the network administrator ignores it and leads to twists and turns in the troubleshooting process. Now I will share it with you to discuss it! The network structure of the LAN in a building is very simple. About 100 computers are distributed on the sixth floor. The computers on each

concerned about the RF interface, its testing and troubleshooting technology should be completely different from the wired LAN. ” Integrate wired and Wireless LAN Security solutions, would anyone like to? Integrated integration systems such as SonicWALL and fortinet security companies can provide integrated solutions for small, simple companies. Security companies have expanded their UTM (Unified threat

professional and effective FTP solution. WINDOWS Lan problems have been plagued since the 95/98 era. When Using XP, WINDOWS Lan problems may occur more or less. Sometimes, when a file is urgently needed, it is forced to use MSN or TM for transmission, however, only one file can be uploaded at a time. You can choose to package or upload files one by one. This is a temporary solution, because it is a waste o
