In-depth analysis of Wireless Router Network keys and SSID Broadcast

Wireless routers have been widely used by the masses. It does not matter if many people do not know the wireless router's network keys and SSID broadcast. After reading this article, you must have gained a lot, I hope this article will teach you more things. Major brand manufacturers have added methods such as keys and forbidden SSID broadcasting in the configuration design of wireless routers. Are these security settings really effective?

As more and more friends enter the "wireless School" family, the security of wireless networks has attracted much attention. Relatively speaking, wireless networks are more difficult to protect than wired networks, because the number of fixed physical access points in a wired network is limited, and any point that can be achieved by the wireless network signal may be used. Therefore, major brand manufacturers have added methods such as keys and forbidden SSID broadcasting in the configuration design of wireless routers. Are these security settings really effective? The following uses wireless devices that support the IEEE 802.11g standard as an example to illustrate how to solve the problems one by one.

Set network key

The wireless encryption protocol (WEP) is a standard method for encrypting data transmitted in wireless networks. Currently, most wireless devices only have WEP encryption, and more secure WPA encryption is not widely used. Currently, there are two key types for a wireless router or AP. For example, the used wireless router has a 64-bit and 128-bit encryption type. Enter 10 or 26 strings as the encryption password () respectively ().

We would like to remind you that the data transmission encryption function is disabled when many wireless routers or APs are leaving the factory. If you use it without further settings, then your wireless network becomes a "undefended" decoration. Therefore, it is extremely important to set encryption for your wireless network. Test results: the 64-bit encryption method is used. During the test, the existence of the wireless Network is found through software such as Network Stumbler. However, the wireless Network cannot be used because the password cannot be obtained.

Disable SSID Broadcast

In general, the SSID is the name you give your wireless network. Note that the wireless routers or APS launched by the same manufacturer use the same SSID. Once attackers attempt to connect to the wireless network using a common initialization string, it is easy to establish an illegal connection, which poses a threat to our wireless network. Therefore, it is recommended that you name the SSID as a personal name.

A wireless router generally provides the "allow SSID broadcast" function. If you do not want your wireless network to be searched by someone else using the SSID name, you 'd better "Disable SSID broadcast ". Your Wireless Network can still be used, but it will not appear in the list of available networks found by others. TIPS: After the SSID broadcast is disabled, the efficiency of the wireless network will be affected. However, in exchange for improved security, it is worthwhile. Test results: because no SSID is broadcast, the wireless network is ignored by the wireless network adapter, especially when Windows XP is used to manage the wireless network, it achieves the goal of "Hiding eyes and ears.
