Because clients connected to a &quot;hidden&quot; SSID broadcast -in cleartext- that AP&#x27;s SSID in many frames that they and the AP transmit as a normal part of operation, [0] deactivating SSID broadcasts gains you no security, a <i>fair</i> bit of inconvenience, and -potentially- reduced battery life when you move out of range of the AP as the client spams &quot;are you here?&quot; messages, rather than taking the absence of SSID broadcasts as a sign that it&#x27;s out of range of the AP.<p>Now, you <i>could</i> &quot;hide&quot; your SSID to reduce the number of SSIDs that appear in a WiFi network browser in a congested area... but that&#x27;s a thing that -IMO- doesn&#x27;t get you much for the hassle.<p>For security, either use WPA2-Personal in AES&#x2F;CCMP-only mode with a long, randomly-generated password, or WPA2-Enterprise [1] in the same mode.<p>[0] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Network_cloaking#False_Sense_of_Security" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Network_cloaking#False_Sense_o...</a><p>[1] Maybe even with client authorization through certs! :D
