Wireless network systems can cause serious security problems if they do not take appropriate security measures, whether the wireless system is installed at home or in the office. In fact, some providers of Internet services for residential areas have banned users and other unauthorized people from sharing networking services in their service agreements. An insecure wireless network can cause services to be lost or exploited to launch attacks on other networks. To avoid some of the similar wirele

There are several possible causes for this failure: (1) wireless network card distance from the wireless AP or wireless router is too far, more than the coverage of wireless networks, wireless signal to reach the wireless network card has been very weak, so that wireless clients can not be normal connection. (2) The wireless AP or wireless router does not power up or does not work properly, causing the wireless client to not connect at all. (3) When the wireless client distance from the wir

First of all, let's take a look at some of the wireless product hardware indicators: transmission power, acceptance sensitivity and antenna gain. At

wireless bridge connects an antenna to form a bridging relay to ensure high-speed wireless link communication. The two back-to-back APS can be in different frequencies and work in the wireless bridge mode at the same time, so that their functions can be expanded and the signal can be maximized during the forwarding process. Increase the bandwidth and speed to the maximum, so as to meet the high requirements of users, to ensure their smooth degree.

The starting point of establishing a secure wireless network access node (access point) is to prevent information leakage from unauthorized external access. This principle is often difficult to understand. The security settings of wireless networks are much more complex than those of ordinary cable networks, because the access nodes of the cable networks are fixed and within the signal sending and receiving range of wireless networks, all nodes can be connected. Problems caused by the characteri

The previous article introduced the basic introduction of the built-in wireless network card. I think you have some knowledge about some common types of built-in wireless NICs. Next we will talk about the selection and upgrade of the built-in wireless network card. Hope to help you. ◆ How to select and upgrade a built-in wireless network card If conditions permit, you can choose a laptop with a built-in wireless network card, which is more convenient to use. Of course, laptops with built-in wire

confidence, and it will never be "fooled ". These four aspects are: Brand and design, quality and performance, simple and easy to use, and the key is price. 1) brand and Design Needless to say, a large brand determines everything about the product, and network products are no exception. A good brand includes the product quality, quality, and after-sales service. Please note: do not purchase products from small factories. The products of small manufacturers cannot guarantee quality or provide st

GPRS card. I will explain for you how to install and use the wireless network card when using the hardware device: wireless network card is a product from South Korea's different show YISO, notebook is COMPAQ's EVO N800C. When I first selected yixiu YISO, the wireless network interfaces on the market were not as rich as they are today, and there were not so many products of domestic brands, and the price was high. Yixiu adopts the built-in antenna an

"service unavailability" or become a stepping stone to attack other networks ". To minimize the risks caused by security vulnerabilities, make sure that network technicians configure and test according to the following suggestions. Wireless Network Application configuration 1. Configure the antenna installation location This is the first step to achieve "non-leak" wireless access nodes. the wireless signal coverage is used to determine the location o

network nodes. These data streams reassemble the files at the specified receiver ." To meet these requirements, a network software stack must handle dynamically changing network configurations. As a result, the network is already focusing on their new research. Antenna design is the key The key to wireless body networks is the design of antennas. According to the school's website, the ideal antenna used by

Misunderstanding 1. The stronger the signal, the better. First, let's take a look at several hardware metrics of wireless products: transmit power, accept sensitivity, and antenna gain. At present, the main disadvantage of wireless networks is signal coverage and transmission rate. Generally, the method to enhance the signal is to increase the transmit power and antenna gain. Transmit power: wireless device

, and other Wi-Fi devices are automatically connected to the Wi-Fi network (even if these devices do not need to actually use the Wi-Fi network ), it also affects the performance experience of the entire network. The result of all this interference is that Wi-Fi network packet loss is serious, resulting in wireless devices have to resend data, which leads to further network congestion. Due to the insufficient wi-fi antenna performance of many mobile d

Do not place the antenna next to the window because the glass cannot block

used to set up a wireless network. In this way, network resources can be shared in a wireless mode with an existing wired architecture. Q3: Will WLAN interference or affect the operation of other devices? ANS: basically, the frequency band used by wireless networks is within the high frequency range of ISM 2.4GHz. It does not interfere with the electrical appliances used in daily life or office, because the frequency is quite different, in addition, the wireless network itself has 12 channels a

At the same time, using the CCA technology can automatically avoid channel interference and take full advantage of channel bundling.I'm interested in this dual-built antenna, so I took this guy apart and looked at the internal structure. 650) this. width = 650; "onclick = 'window. open (" http://blog.51cto.com/viewpic.php?refimg= "+ This. src) 'alt =" "src =" http://www.bkjia.com/uploads/allimg/131227/03
