A sales rep reports that her Android phone suddenly stopped connecting to the office Wi-Fi network after IT changed the wireless passphrase earlier that morning. The handset sees the SSID and tries to join, but after a few seconds it shows "Saved, secured" and displays an APIPA address in the 169.254.x.x range. Other employees using the new passphrase have no issues. Which action should the technician try first to restore Wi-Fi connectivity?
Forget the saved Wi-Fi network and reconnect, entering the new passphrase
Toggle Airplane mode off and on to refresh the wireless radios
Disable randomized MAC addressing for the SSID
Reset the phone's VPN settings and retry the connection
Because the phone still holds the old, now-invalid credentials, the access point rejects its authentication attempt, preventing DHCP from assigning an address and leaving the handset with an APIPA address. Removing the stored profile forces the device to discard the cached PSK and prompt for the new one, allowing a normal handshake and DHCP lease. The other options do not address the incorrect credentials that are blocking association.
