how to secure unsecured wireless network

greatly enhanced; WPA enhances the algorithm for generating encryption keys, even if hackers collect and parse group information, it is almost impossible to calculate a general key. The emergence of WPA makes network transmission more secure and reliable. Wireless Network Security Settings 3: SSID Broadcast In short,

A loop problem occurs in the use of wireless networks. Where is the problem? Who is the culprit? The author of this article gives you a detailed description of how to set up your own experience. Unit A subnet has been working normally, but I found that workstations in subnet A recently cannot access the LAN server. After some careful checks, I can see that the new switch devices in subnet A are often unable to connect to the core switches in the LAN.

services. Retailers can choose places without communication lines, such as stadiums, trade fairs, concerts, and temporary commercial activities. B. Quick: after testing, the bill is printed from the magnetic card to the POS machine after receiving the confirmation data. The entire process is only 4 ~ 8 seconds, far less than the transaction time of the POS machine through the telephone line. C. Security: It is very secure and reliable. Using GPRS

speed will be improved to a certain extent. Open DMZ function In addition to using UPnP to solve the problem of extranet and intranet, we also need to use the DMZ (Demilitarizedzone) to solve the problem that the external network cannot access the Internal network server after installing the firewall. in order to ensure that the Peer-to-peer tools such as BT are not limited to the maximum degree of sm

general key. The emergence of WPA makes network transmission more secure and reliable. Wireless Network Security Settings 3: SSID Broadcast In short, the SSID is the name you give your wireless network. When searching for a

driver. If the overall wireless network of an enterprise runs well and the network is unstable on a single machine, the problem will inevitably occur on a single machine. First, the replacement method is used to check the running performance of the wireless network card. Wh

connect to the target wireless network smoothly through the scanned SSID information and WEP Key. V. Summary: This document describes how to use a boot disc in a Windows environment to directly crack and restore the WEP encryption key of the wireless network. This method has two main features, the whole process of th

security of this wireless network, and does not explain why this technology is secure. It is obvious that, as a potential customer, I was able to raise such a simple question. They even felt very ridiculous and seemed to have a bad attitude towards me, he does not want to answer any questions except for asking me to leave the booth. Of course, this exhibition st

mysql| Security | access | server | data | database | Network MySQL security system is flexible. It allows you to set user access rights in many different ways. Typically, the grant and REVOKE statements are used to modify the authorization table that controls client access. However, you may have an older version of MySQL that does not support these statements in the previous version of MySQL3.22.11 , or it may be found that the user's permissions do

After learning about the basic knowledge of wireless NICs, let's talk about the precautions for purchasing wireless NICs and the use of wireless devices such as wireless NICs and wireless NICs. First, we will focus on the three elements of

collect and parse group information, it is almost impossible to calculate a general key. The emergence of WPA makes network transmission more secure and reliable. It should be noted that the wireless encryption function is usually disabled when a wireless router leaves the factory, but if you give up this function, yo

security of your network, do not use WEP as much as possible in the future, because it is really not very secure. 　　The WPA-PSK (TKIP) The first security mechanism adopted by wireless networks was WEP (equivalent wired encryption). However, it was found that WEP was insecure, and 802.11 organizations began to develop new security standards, that is, the later 80

. When building a wireless network, the biggest problem encountered is the placement of the Wireless Broadband Router. You must select a suitable location. There is also no relationship between the IP address of the wireless router and the IP address of the access network, b

In the enterprise architecture wireless network, we need to prepare in advance to comprehensively investigate the enterprise environment and make a complete plan to develop a suitable wireless network solution. Now we will introduce a Cisco Aironet Series Wireless

Configuration options for common wireless hotspots:Wireless NameThe wireless (Wi-Fi) name of the router.Wireless passwordWireless encryption using WPA2-PSK/WPA-PSK encryption method, AES encryption algorithm, wireless password is 8-63 characters, preferably a combination of numbers, letters, symbols.ChannelWireless data signal transmission channels, it is recomme

The continuous deepening of the network application, people's dependence on the network has become more and more strong, has been the work and life of people are indispensable tools. But as the environment changes and the needs of the way to update, Mobile has become the trend of network office, and the current wired network
