8. A computer provided with a wireless communication module, including:
-
a scanning controller that controls access point scanning; and
a detection unit that detects whether or not communication with an access point is enabled; and
said scanning controller, when said detection unit detects that communication with said access point is disabled, sets an idle time until the next access point scanning begins, longer than when said detection unit detects that said communication with said access point is enabled. - View Dependent Claims (9)

10. A wireless communication module that sends/receives data to/from an access point, comprising:
-
a scanning unit that scans an access point;
a detection unit that detects whether or not communication with said access point is enabled according to a result of scanning; and
an operation mode controller that controls an operation mode that selects a unit to be supplied with a power in said wireless communication module according to the decision of said detection unit. - View Dependent Claims (11, 12, 13)

14. A wireless communication module connected to a computer and used to enable said computer to connect another device for wireless communication, comprising:
-
a first mode operation unit that operates said wireless communication module in a first mode when an AC power supply is used to power said computer; and
a second mode operation unit that operates said wireless communication module in a second mode when said AC power supply is not used to power said computer. - View Dependent Claims (15, 16)

17. A method for controlling a wireless communication module that sends/receives data to/from an external network, comprising:
-
a step of scanning an access point;
a step of detecting whether or not communication with said access point is enabled; and
a step of setting t1 as an idle time until the next scanning begins when communication with said access point is enabled and sets t2 as an idle time until the next scanning begins when communication with said access point is disabled; and
said t1 and said t2 satisfy the condition of t1<
t2. - View Dependent Claims (18, 19)

20. A program that enables a computer to execute:
-
a function for setting a first mode as an operation mode of a wireless communication module when an AC power supply is used to power said computer; and
a function for setting a second mode as said operation mode of said wireless communication module when said AC power supply is not used to power said computer. - View Dependent Claims (21, 22)

23. A recording medium that records a program to be executed by a computer so as to be read by said computer,
wherein said program enables said computer to execute: -
a function for detecting whether or not an AC power supply is used to power said computer; and
a function for setting a first mode as an operation mode of a wireless communication module when said AC power supply is used
to power said computer and sets a second mode as said operation mode of said wireless communication module when said AC power supply is not used to power said computer. - View Dependent Claims (24)
