A wireless communications device with a wireless module and a controller module is provided. The wireless module is arranged for performing wireless transmission and reception to and from a service network. The controller module is arranged for receiving a first ciphered data packet from the service network via the wireless module, and deciphering the first ciphered data packet according to a first deciphering parameter. Also, the controller module is arranged for deciphering the first ciphered data packet according to a second deciphering parameter in response to unsuccessful deciphering of the first ciphered data packet according to the first deciphering parameter. Particularly, the second deciphering parameter is for deciphering a second ciphered data packet received prior to the first ciphered data packet from the service network. |
