Multi-WLAN port router Principle AnalysisAt present, there are many vrouters with multiple WAN ports (WAN interfaces) on the market. Many people ask if the multi-WAN port vro is better than a single WAN port vro? In which scenarios do I need a multi-WAN router? What is the purpose of a Multi-Wan port router? How to use it? What are the benefits of using it? Below we take TP-LINK dual WAN port router TL-R480 + and multi WAN port router TL-R488 as an ex
confused about the network to be connected, which may cause a lot of trouble.
In short, because the SSID can be easily detected, hiding the SSID is almost impossible to provide security opportunities. It can be said that it is not so much a hindrance to attackers as it is a hassle for legitimate users in their own units.
Iii. time slice wireless Intrusion Detection
There are two main methods to perform Intrusion Detection for configuring wireless networks. One is through a dedicated detector, a
Intel Wireless Network deployment
The irresistible charm of wireless networks has prompted intel to start deploying 802.11b-standard WLAN for 80 thousand employees across the company ). The 802.11b wireless standard is favored by Intel because it provides seamless wireless connections, which can significantly improve network access performance and improve the company's productivity.
This has become more practical as more and more Intel employees begi
There are still many things worth learning about wireless LAN. Here we will mainly introduce the Selection Guide for WLAN products related to wireless LAN. Experts believe that to purchase a wireless LAN product, we must first clarify the protocol types of the wireless LAN, then consider the performance of the wireless LAN gateway, and consider the security performance of the wireless product, finally, you can purchase a suitable Wireless LAN product
to the relevant instructions. Note that the wireless network card must be in the same IP segment as the wireless router.
Next, open your browser and enter the address of the wireless network node in the address bar, such as http: // 192.168.254.254/. view the manual and obtain the management password of the wireless network node, after correct input, you can enter the management interface of the wireless network node. For a new router that has not been set up, some will also display the Setup W
. Then went down to get the short feeder, after the new connection. Field test signal strength changed to-45 or so, very good. Call the customer to start the new computer and try again. The customer reflects or does not have a signal to search. This analysis is the problem of the client computer itself. 3. then came to the customer's home, using our notebook test everything is normal. Wireless Zero Configuar Wireless Configuration service is not turned on with the customer's computer, resulting
1. In the Windows 7 system we clicked on the "Wireless Network icon" on the taskbar and then we clicked on the Open Network and Sharing Center on the opening screen as shown in the picture.
2. Then we click to open the "Network Sharing Center window" and there is a "manage wireless network" on the left and then we click again.
3. It will then show all the wireless networks that have been successfully connected to the current computer, select the network that is not currently connected, and
With the rapid development of intelligent terminals and operators, mobile data traffic is exploding, which brings unprecedented data transmission pressure to 3G network.
Wireless LAN is designed for indoor environment and can withstand quite high data throughput, so wireless LAN can meet the needs of indoor mobile data service. 3G Network in the outdoor area to provide users with wide coverage, high mobility, high service quality of the business; Wireless LAN in the indoor area to provide users
In our daily computer office, the most can not suffer from the network problem, in the Windows system, the cause of network failure There are many kinds, if it is a win7 system, when a network failure, in the lower right corner of the system taskbar, will show a red fork or network icon display yellow exclamation mark, For this problem we usually troubleshoot the WLAN AutoConfig service process, but there are some Win7 users to open the service, there
In the development of Wired Network (hereinafter referred to as LAN) in the ascendant, wireless local area network (hereinafter referred to as WLAN) with the technology gradually mature and product costs continue to reduce, unknowingly has crept into our work and life.
The widespread spread of WLAN and broadband also makes related failures happen, so let's take a look at common wireless LAN failures.

Compared with wired networks, wireless network security issues have the following characteristics: (1) open channels cannot prevent attackers from eavesdropping, malicious modification, and forwarding; (2) transmission media-the propagation of radio waves in the air may cause signal attenuation due to various reasons (such as obstacles), resulting in unstable or even lost information. (3) mobile devices (especially mobile users) are often needed, and devices are pr
software firewalls. Of course, broadband access is certainly indispensable. 3 floors are shown in the figure 8-50 ). There are 6 IEEE 802.11a or 802.11g standard AP bridges on each floor, and the AP bridge is placed on the aisle ceiling. Generally, a main aisle requires two or more wireless access points, the antenna of the AP bridge must be down, so do not be blocked by the ceiling or other objects ).
