A Wireless Fidelity (WI-FI) connection method and a mobile terminal for efficiently connecting to hidden access points. X parameters of a target Access Point (AP) are acquired, the X parameters at least includes the target SSID of the target AP, where X is a positive integer. WI-FI scanning is performed according to the X parameters. When the target AP is not found by the scanning, encryption schemes of one or more hidden APs are acquired to get the H encryption schemes, where H is a positive integer. WI-FI scanning is performed according to the target SSID and at least one of the H encryption schemes.
