Communication apparatus and network search method thereof

摘要

A network search method for a communication apparatus connected to a network is disclosed. The method comprises the following steps. The communication apparatus enters a sleep mode when the communication apparatus loses signals from the network. Then, power status of the communication apparatus is detected. A trigger signal is automatically sent when a change in power status of the communication apparatus is found. Next, a radio frequency module is enabled to search for the signals from the network according to the trigger signal so as to reconnect to the network.
