Cracking the WEP Key process (Part 1)

can support a wide range of wireless network adapters, we recommend using a prism 2 Chip-based network adapter, this chip can be supported by all the tools we need to use during the cracking process. Wireless NICs generally have two types of antennas: External antennas and built-in antennas. If the purchased wireless NICs do not have built-in antennas, you must purchase another one. However, the advantage of an external antenna is higher gain and bet

A brief analysis of mobile communication jamming

CDMA networks, because the system uses Code division multiple access technology, all users use the same frequency band, mutual use of unrelated PN code as a spread code to differentiate, because of this feature, the existence of the same frequency interference is inevitable; at the same time, the amount of interference depends on the number of telephone users, the system capacity also changes (that is, soft capacity). From the subjective aspect, the main reasons for the same frequency interfer

wall blocking between them, especially the reinforced cement wall of the load-bearing wall ). We know that in order to reduce the radiation to the human body, the power of the wireless router is generally not large, so the capacity is subject to interference from nearby electronic devices during use, therefore, when setting the placement of wireless routers, we must remember to stay away from microwave ovens, refrigerators, and other household appliances. A good

Wireless Router transmission and Its Influencing Factors

A good antenna is also an effective way to ensure the wireless transmission distance and Stability of routers. Some high-end wireless routers use dual antennas, generally, multi-antenna products

Six simple settings ensure the security of wireless network applications

Why do we need to close the network line?The key to ensuring the security of wireless access points is to prohibit unauthorized users from accessing the network. That is to say, a secure access point is disabled for unauthorized users. Ensuring the security of wireless networks is much more difficult than ensuring the security of wired networks. Because the wired network only has a limited number of fixed access points, and the wireless network can be connected from any point in the range permit

Basic mobile phone R & D process

place the antenna in a relatively large area, and the distance from the battery is also far enough. HW also requires the id not to place any gold accessories near the antenna. We can imagine that the manufacturing cost of a mobile phone with a built-in antenna is 20-25% more expensive than that of a mobile phone with an external

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

Six simple measures for Wireless Network Security

than ensuring the security of wired networks. Because the wired network only has a limited number of fixed access points, and the wireless network can be connected from any point in the range permitted by the antenna. Design antenna placement The first step to keep the Wireless Access Point Closed is to place the antenna correctly, so as to limit the semaphores

Tips 3: Search for antennas and crack the network In this way, you need to pay a certain amount of money to purchase a "strong search antenna", but the effect is "immediate" and very effective. This kind of powerful search antenna is actually the "secondary network card" mentioned at the beginning of this article. The price of this kind of equipment is between-RMB. Its principle is ver

Six steps to ensure the security of wireless network applications

With the development of network technology, wireless network security has become more and more important. From what perspectives should we set up? Next we will introduce it to you. Why should I disable the network line for wireless network application security? The key to ensuring the security of wireless access points is to prohibit unauthorized users from accessing the network. That is to say, a secure access point is disabled for unauthorized users. Ensuring the security of wireless networks

, therefore, when setting the placement of wireless routers, we must remember to stay away from microwave ovens, refrigerators, and other household appliances. A good antenna is also an effective way to ensure the wireless transmission distance and Stability of routers. Some high-end wireless routers use dual antennas, generally, multi-antenna products are more secure than single-

Build a wireless LAN: adapt to local conditions

LAN has many incomparable advantages. For example, the layout of Wireless LAN is not subject to physical location restrictions, and the erection cost is not as high as that of wired LAN, the successfully deployed wireless LAN can be easily changed in the future. More importantly, the expansion of the wireless LAN network is very good. For example, it can be compatible with various network connection interface standards, supports and complies with all communication protocol standards. For common

How to display the wireless router rationally

transmission distance is not a problem. But the family environment has brought a new problem, that is the family space is more crowded, the space is not open, in which the walls of the room is the main obstacle. Because Wireless LAN uses the wireless microwave frequency band. The most characteristic of microwaves is that it is almost linear and the diffraction ability is very weak, so the wireless receiving device behind the obstacle receives a faint signal or does not receive a signal. What ab

How to make wireless internet fast and stable

Wireless AttacK Defense: detailed explanation of cracking WEP keys

machines use two PRISM chip-based 802.11b wireless NICs. Although many tools (such as Kismet) used in subsequent operations can support a wide range of wireless network adapters, we recommend using a PRISM 2 Chip-based network adapter, this chip can be supported by all the tools we need to use during the cracking process.Wireless NICs generally have two types of antennas: External antennas and built-in antennas. If the purchased wireless NICs do not have built-in antennas, you must purchase ano

Three guidelines for purchasing Wireless Network Interfaces

, flexible compatibility with desktop and laptop, this is the greatest temptation. We recommend that you do not consider the SD interface or Express card interface products for the time being. SD-interface wireless NICs require devices to have SDIO interfaces, which are only supported by a few PDAs and are expensive. As for the Express card interface, although it does not doubt the long-term trend of replacing the PCMCIA Interface, at least it is too advanced. Option 2 for wireless network adap
