注释:SSID
SSID/ESSID(Service Set Identifier)也就是“服务区标识符匹配”、“业务组标识符”的简称,最多可以有32 个字符,通俗的说,它就好比有线局域网中的“工作组”标识一样或好比是无线客户端与无线路由器之间的一道口令一样,只有在完全相同的前提下才能让无线网卡访问无线路由器,这也是保证无线网络安全的重要措施之一。
配备无线网卡的无线工作站必须填写正确的SSID,并与无线访问点(AP 或无线路由器)的SSID相同,才能访问AP;如果出示的SSID 与AP 或无线路由器的SSID 不同,那么AP 将拒绝他通过本服务区/工作组上网。因此可以认为SSID 是一个简单的口令,从而提供口令认证机制,实现一定的安全。
要更改无线网卡的SSID 除了在无线网卡配置程序中更改外,还可在操作系统中直接更改。
