Wi-Fi is inherently vulnerable to hacker attacks and eavesdropping. However, if you use the correct security measures, Wi-Fi can be safe. Unfortunately, the site is full of outdated advice and misunderstandings. Here are some of the things you should do and shouldn't do in Wi-Fi security. 　　1. Do not use WEP WEP (Wired Equivalent encryption protocol) security has long been dead. Most inexperienced hackers can quickly and easily break through basic encryption. Therefore, you should not use WEP

Know how to rub the network card "Rub network card" is a WiFi Wireless LAN network card, compared with the standard wireless network card, mainly has the following characteristics: 1. High transmitting power China does not appoint the antenna gain less than 10dBi of 2.4GHz Wireless LAN products equivalent total radiation power (EIRP) must be less than or equal to 100mW, the EU CE Certification standard also stipulates 2.4GHz Wireless LAN products equivalent total radiated power (EIRP) to be l

In practical application, there are some problems in the SP1 of wpa/wpa2de compatibility. There will still be an inability to connect to the de situation. Upgrade the operating system. Either Windows 7, Vista, or XP SP3. They p

, network fraud. VPN can also be used to protect wireless network traffic for Wireless LAN transmissions if the virtual personal network (VPN) has been used to protect enterprise data in the public network. This ensures the security of data transmission away from the office point and extends the area of security. Others use VPNs to protect wireless networks in the field-especially those that were earlier using the WEP (Wired Equivalent Privacy) protocol. Fortunately, all wireless network-licen

unauthorized access through a network security key. To set up your network security key, follow these steps: Open Network and Sharing Center by clicking the Start button, and then clicking Control Panel. In the search box, type Network, and then click Network and Sharing Center. Click Set up a new connection or network. Click Set up a new network, and then click Next. The wizard will guide you through the creation of a network name and security key. If your router supports it, the wizard

WEP-based encryption describes D-Link Wireless route settings. For vrouters of various models, the following is a Q A topic on D-Link Wireless route settings, we hope to include all questions about the use of vro upgrades. DI-624 + A, DI-724UP + A is two super high-performance wireless router, can easily build A small and medium-sized enterprises at the same time the Internet environment, and has A strong firewall security characteristics, can be based on MAC address, filters IP addresses, URLs

only crack WEP encryption, for the use of WPA-PSK/WPA2-PSKAES encryption wireless router is powerless, so as long as you choose the appropriate encryption method, it can prevent malicious network attacks. Second, how can we prevent network attacks? The above describes the features of the "ENI" and it is easier to prevent network attacks. All TP-LINK wireless routers support WPA-PSK/WPA2-PSK security when y

others to know what they have written, in this way, only emails with protection level can be seen only when the envelope is damaged. This is like cracking the wireless network password. Then, EMS is like high-level wireless network encryption mode, it can greatly protect the security of wireless network information transmission. Wireless encryption options in wireless routers Currently, the wireless router has the following encryption modes: WEP, WPA-PSK (TKIP),

Failure phenomena:The two SSID emitted on the same AP, but the two SSID is in a different network interface, but it is found that the user will have a 54M rate when connected to the SSID1, but if the client is connected with SSID2, then the 11n or 11a rate will occur.Problem Analysis:First of all, see why all users Only connect to SSID 1 will appear 54M, because the network protocol is connected to 11a, and the connection to the SSID 2 will occur after the rate of 108m, because the network proto

Wifi Analyzer | Local download Wifi Analyzer is a free Android app. You can find an AP on a mobile terminal of the Android platform. It lists all the details of the ap in the GHz channel and supports other devices in the 5 GHz channel. You can also share AP details in XML format by email or other applications or screenshots. It is

small and medium-sized enterprise networks or home users, WPA also provides a simplified mode that does not require dedicated Authentication servers. This mode is called "WPA pre-shared key (WPA-PSK)", which requires only one key in advance on each WLAN node (AP, wireless router, Nic, etc.This key is only used for authentication, not for data transmission encryption. The data encryption key is dynamically generated after authentication. The system will ensure "one user and one password". There

(3) Use the corresponding Internet access control software, such as the P2P Terminator. Generally, the software displays all the computers connected to the same vro and the download speed. Next, let's briefly talk about the methods used by the network owner! Generally, wireless routers and APS support WEP, WPA, and wpa2 encrypt

Hostapd introduction: To put it simply, hostapd can switch the wireless network adapter to the master mode and simulate the AP (which can be considered as a router) function, that is, the soft AP we call it ). As an AP authentication server, hostapd is responsible for controlling and managing the access and authentication of stations (usually a PC with a wireless network card. You can use hostapd to switch the wireless network adapter to the AP/master mode. By modifying the configuration file, y

Let's look at how to set up the Network Wizard to guide you through the process of setting up the security key. Click the Start button-and then click Control Panel-to open set up network. In the search box, type Network-and then click Network and Sharing Center-"Set up a new connection or network"-"set up a new network." 　The encryption method of wireless network There are currently three types of wireless network encryption: WI?

HOSTAPD Introduction: Simply put, HOSTAPD can make the wireless card switch to master mode, analog AP (usually can be considered as a router) function, that is, we say the soft AP (Soft AP). The function of HOSTAPD is to be the AP's authentication server, which is responsible for the access and authentication of the management stations (which can usually be considered as a PC with a wireless network card). By HOSTAPD, the wireless network card can be switched to Ap/master mode, and an open (unen

With the development of business at full speed, the related wireless LAN (WLANs) is also moving towards a larger and faster direction. Therefore, many factors need to be considered, including security issues. 802.11n can expand network coverage and performance, but it also needs to consider the same or better security as in the past. A brief history of past wireless IEEE802.11a/B/g Standards Like the original 802.11a/B/g standard, the 802.11n high throughput standard has the robust security (rob

page, you can choose whether to disable the wireless security function. A. If you do not need to enable the wireless security feature, check the disable wireless security option to disable the wireless security feature. B. If you need to enable wireless security, select one of the three security types on the page for wireless security settings. This page provides three wireless security types: WEP, WPA/WPA2, and WPA-PSK/
