注釋：SSID

SSID/ESSID（Service Set Identifier）也就是“服務區標識符匹配”、“業務組標識符”的簡稱，最多可以有32 個字符，通俗的說，它就好比有線局域網中的“工作組”標識一樣或好比是無線客戶端與無線路由器之間的一道口令一樣，只有在完全相同的前提下才能讓無線網卡訪問無線路由器，這也是保證無線網絡安全的重要措施之一。

配備無線網卡的無線工作站必須填寫正確的SSID，并與無線訪問點（AP 或無線路由器）的SSID相同，才能訪問AP；如果出示的SSID 與AP 或無線路由器的SSID 不同，那么AP 將拒絕他通過本服務區/工作組上網。因此可以認為SSID 是一個簡單的口令，從而提供口令認證機制，實現一定的安全。

要更改無線網卡的SSID 除了在無線網卡配置程序中更改外，還可在操作系統中直接更改。
