SSID(Service Set Identifier)

SSID(Service Set Identifier) technology may put a wireless LAN is divided into several need different identity authentication son network, every one statures network all need separate identity authentication, it is only through the identity authentication user is allowed to enter the corresponding son network to prevent unauthorized users access to the network
What is the SSID?
SSID can also write for ESSID, used to distinguish different network, a maximum of 32 characters, wireless network card set up different SSID can enter in different network, usually by SSID broadcasting out, through the AP own scanning function can XP check the current regional SSID. For security reasons can not, then the user will broadcast SSID manually set SSID can enter the corresponding network. Simply said, SSID is a LAN, the name of the same name only Settings for the computer to the value of the SSID write to each other.
Disable SSID broadcasting
Popularly say, SSID is you give yourself the wireless network's name. Note that the same producer introduced wireless router or AP used the same SSID, once those who attempt to illegal connect the attacker to make use of universal initialization string to connect to wireless networks, is extremely easy to establish a illegal connection, to give our wireless network pose a threat. Accordingly, the proposal is best can will SSID named some more have character name.
Wireless router usually provide "allow SSID broadcasting" function. If you don't want to let oneself of wireless network by others through SSID names search to, so best "prohibited SSID broadcasting". Your wireless networks are still can use, but others do not appear on the available Internet search list. Tip: by banning SSID broadcasting after setting, wireless networks efficiency will be affected by certain effect, but in return for the improvement of safety, the author thinks that are worth it.
Test results: because no SSID broadcasting, the wireless network by wireless card ignored, especially in using Windows XP management wireless network, reached the "camouflage" purposes.
