Patent ID: 8290488

Claim:
A scanning method for wireless networks for use in an electronic device, comprising: receiving an operation initiating a wireless network scanning procedure; in response to the operation, changing at least a waiting time corresponding to the wireless network scanning procedure from a default time length to a predefined time length; performing the wireless network scanning procedure according to the predefined time length, wherein the step of performing the wireless network scanning procedure according to the predefined time length comprises the steps of: determining whether a specific wireless access point detected in a second scanning operation is also detected in a first scanning operation, wherein the second scanning operation is performed preceding the first scanning operation; if the specific wireless access point detected in the second scanning operation is not detected in the first scanning operation, subtracting an alive count corresponding to the specific wireless access point by a predefined value; determining whether the alive count corresponding to the specific wireless access point equals to a specific value, wherein the specific value is a preset integer; and if the alive count does not equal to the specific value, displaying the specific wireless access point having the alive count not equal to the specific value and at least one wireless access point detected in the first scanning operation via a user interface; and when the wireless network scanning procedure is terminated, changing the waiting time from the predefined time length back to the default time length.
