SSID是Service Set Identifier的缩写,意思是：服务集标识。许多人认为可以将SSID写成ESSID,其实不然,SSID是个笼统的概念,包含了ESSID和BSSID,用来区分不同的网络,最多可以有32个字符,无线网卡设置了不同的SSID就可以进入不同网络,SSI...SSID是Service Set Identifier的缩写,意思是：服务集标识。许多人认为可以将SSID写成ESSID,其实不然,SSID是个笼统的概念,包含了ESSID和BSSID,用来区分不同的网络,最多可以有32个字符,无线网卡设置了不同的SSID就可以进入不同网络,SSID通常由AP广播出来,通过XP自带的扫描功能可以查看当前区域内的SSID。出于安全考虑可以不广播SSID,展开更多
