encryption and WPA encryption functions. WEP generally includes 64-bit and 128-bit encryption types, you only need to enter 10 or 26 hexadecimal strings as the encryption password to protect the wireless network. The WEP protocol encrypts data transmitted wirelessly between two devices to prevent illegal user eavesdropping or intrusion into the wireless network. However, the WEP Key is generally stored in Flash, therefore, some hackers can use vulner
vro through the assigned IP address, so it is necessary to disable the DHCP function.
Wireless Network Security Settings II: Encryption
Nowadays, many wireless routers have the wireless encryption function, which is an important protection measure for wireless routers. Data Encryption in radio waves ensures the security of transmitted data information. Generally, wireless routers and APs have the WEP encryption and WPA encryption functions. WEP gener

the trouble for others to use. It should be noted that, after hiding the network, Windows Vista users need to set the connection device to "connect even if the network is not broadcast ". You can find this option in the Network Connection Properties in the "manage wireless networks" window.
Step 3: Configure "security mode ". A new vro can have up to three options: WEP, WPA, or wpa2. The difference between the three options is that WEP is an old-fash
"wireless network" tab, and some models have wireless options in "Advanced Settings. However, the settings are similar.
Wireless route security settings Step 02
Set security options. The security option is very important. It allows others to affect the network speed, while others can intrude into your computer through the wireless network, so you can do whatever you want. Therefore, security must be ensured.
1. The main point of this step is to select the correct security mode. We recommend tha
maintain a list of MAC addresses that are allowed to access the AP to filter physical addresses. This scheme requires the MAC address list in the AP to be updated at any time, with poor scalability. In theory, MAC addresses can be forged, so this is also a low level of authorization authentication.
Physical address filtering is a hardware authentication rather than user authentication. This method requires that the MAC address list in the AP be updated at any time. Currently, it is performed ma

It is divided into two parts: one is the server side here refers to a Wireless AP or wireless router with DHCP service function), and the other is the client user's personal computer and other wireless client devices ). All IP network settings are centrally managed by the DHCP server and are responsible for handling the DHCP requirements of the client. The client uses the IP Environment Information allocated from the DHCP server.
If the DHCP function is enabled on the Wireless AP or

Anti-rub first trick: WPA encryption
Using
The attack and prevention of wireless network has always been a hot topic, because wireless signal can be received by anyone within a certain range (including dead black width), which brings a security hazard to WiFi; router manufacturers and Network service providers (ISPs) are mostly configured to have WPS enabled by default, in this environment, Wireless networks are often an important breach of security penetration testing. With these 10 WiFi attack tools, we can test our wireless network fo

WEP cracked
If your home router's wireless encryption is configured for WEP encryption, then you have to change it right away because the WEP encryption system is flawed, and the net-rubbing can be used to restore the password by collecting enough handshake packets (that is, the packet in the authentication process between the computer and the wireless router). The attack success rate of this kind of encryption method is nearly 100%. The more common attack tactic is to use M
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
network device has a unique ID called a MAC address, typically in this format: 00-d8-a1-40-9f-62. You can use him to come outside the door of the intruder. Many routers allow you to set a range of MAC addresses that can be plugged into the Internet. This way you can tell the wireless router which is the MAC address of your own PC, and not be excluded from this range.
