Abstract: Implementations of the present disclosure relate to setting a system time of an access point (AP) for server certificate validation. A method comprises obtaining a default time as a system time of the AP after an AP boots up. The method also comprises obtaining a memory time from a flash memory of the AP. The method also comprises updating the system time with the memory time obtained from the flash memory. The method also comprises validating a server certificate received from an authentication server based on the system time. The system time is synchronized with a network time if the server certificate is successfully validated based on the system time. The synchronized system time is then written into the flash memory. In this way, the authentication can be performed based on a reasonable system time even if the AP reboots.
