Power managing method applied to a wireles network apparatus and power management thereof

摘要

A power managing method applied to a wireless network apparatus (610) includes the steps of periodically detecting whether the wireless network apparatus (610) is operated in a non-link status to determine whether to enter a first power-saving mode when the wireless network apparatus (610) powered on; and determining the wireless network apparatus (610) whether to enter a second power-saving mode according to an information of a beacon received by the wireless network apparatus (610) when the wireless network apparatus (610) is operated in a link status. When the wireless network apparatus (610) is detected to be operated in the non-link status, control the wireless network apparatus (610) to enter the first power-saving mode by a power mode controlling circuit (670). The first power-saving mode is an inactive power-saving mode, and the second power-saving mode is a linked power-saving mode.
