Why are some Wi-Fi networks hidden?
Show answer & explanation
Answer: Reduce unauthorized access
Save router power — Wrong. Broadcasting SSID uses negligible power. Hiding networks is about security—making them harder to find and access.
Reduce unauthorized access ✓ — Correct! Hidden networks don't broadcast their SSID (network name) in beacon frames. This 'security through obscurity' makes networks invisible to casual users scanning for Wi-Fi. However, it's weak protection—determined attackers can detect hidden networks monitoring traffic. Better security: strong WPA3 passwords, MAC filtering, disabling WPS. Hiding SSIDs adds minor barrier but shouldn't be sole protection!
Extend wireless range — Wrong. SSID visibility doesn't affect range. Hiding networks is a mild security measure making them less obvious to unauthorized users.
