The “Scan Wi-Fi” Button: A Small Feature with Big Convenience

Most modern smartphones, from Android to iPhone, come with a built-in feature to scan for public Wi-Fi. Simply go to Settings > Wi-Fi and then choose “Scan for Networks” or tap the refresh icon – this “little button” wonder will help your phone discover all the Wi-Fi networks around you.

Some phones even have an “Auto-Connect to Open Wi-Fi” feature, which means your device will automatically connect to password-free public networks like those in cafes, supermarkets, bus stations, and parks without any extra steps from you.

On Android Phones:

  • Go to Settings > Connections > Wi-Fi

  • Turn on “Connect to open networks” (Auto-connect to open networks)

  • Tap the scan/refresh icon in the corner to update the Wi-Fi list

If your device detects a public network that doesn’t require a password, it will connect automatically.

On iPhones:

  • Go to Settings > Wi-Fi

  • Choose “Other Networks…” to find more Wi-Fi options nearby

  • Or simply pull down to refresh the network list, and your device will display all available Wi-Fi networks close by

iOS also has an Auto-Join Hotspot feature, which automatically connects your device to public networks when no private network is available.

Apps to Help You Find Free Wi-Fi

Besides the traditional method, you can use trusted apps that share community-provided passwords for Wi-Fi hotspots, such as:

  • WiFi Map

  • Instabridge

  • OpenSignal

  • Wiman Free WiFi

These apps rely on crowd-sourced data to provide passwords for free Wi-Fi hotspots worldwide.

Precautions When Using Public Wi-Fi

  • Do not enter sensitive information on unfamiliar websites

  • Use a VPN, if possible, to encrypt your data when accessing public networks
