Wireless network connection system and method

An apparatus comprising:

• non-volatile storage device which stores the information of a network to make a wireless LAN connection;
• determination unit which determines whether the connection to the network having its information stored in said non-volatile storage device is possible;
• and
• radio control unit which powers off a transmitting and receiving radio used to make the wireless LAN connection while the power of a system is turned on, only when said determination unit determines that a connection to any of the networks having their information stored in said non-volatile storage device is not possible.

A apparatus comprising:

• a radio which makes a wireless communications via a predetermined access point;
• a connection candidate list storing unit which stores a connection candidate list which includes an information of a network connection;
• a connection unit which attempts a connection to a network included in the connection candidate list stored in said connection candidate list storing unit;
• and
• a set-up unit which sets the information indicating the hidden access point in the connection candidate list when a network name for identifying the network is not confirmed for the network to which the connection is attempted by said connection unit.

An apparatus comprising:

• a radio which makes a wireless communications via a predetermined access point;
• an attitude fluctuation sensing unit which senses an attitude fluctuation of said apparatus;
• and
• radio control unit which powers on a transmitting and receiving radio which makes the wireless communications on the basis of the attitude fluctuation of said apparatus sensed by said attitude fluctuation sensing unit.

An apparatus comprising:

• a radio which makes a wireless communications via a predetermined access point;
• an attitude fluctuation sensing unit for sensing an attitude fluctuation of the apparatus;
• and
• a scan executing unit which executes a scan for the access point on the basis of the attitude fluctuation of said apparatus sensed by said attitude fluctuation sensing unit.

A method comprising the steps of:

• connecting to a predetermined wireless network through a connection point;
• acquiring a network name by scanning for an access point in an environment where an apparatus is placed;
• acquiring an information of a hidden access point having issued no network name from a connection candidate list of the wireless network stored in a predetermined memory;
• comparing the network name acquired by the scan and the hidden access point acquired from the connection candidate list in an order of priority for the wireless network;
• and
• connecting to the named network which has a higher priority as determined in said comparing step.

A method comprising the steps of:

• connecting to a predetermined wireless network through a connection point;
• acquiring information indicating that an access point for connecting to the wireless network is a hidden access point where an identification information for a connection list table storing the identification information of the wireless network for use by an apparatus to connect to the wireless network is not present;
• and
• confirming the connection to the wireless network by attempting an actual connection to the hidden access point.

A method comprising the steps of:

• connecting to a predetermined wireless network connection;
• confirming whether there is any access point for connection to a wireless network by an apparatus;
• stopping a wireless transmitting and receiving radio when an access point for connection to the wireless network does not exist;
• sensing an attitude fluctuation of the apparatus;
• and
• resuming the wireless transmitting and receiving radio that is stopped on the basis of the sensed attitude fluctuation.

A method comprising the steps of:

• connecting to a predetermined wireless network connection;
• sensing an attitude fluctuation in the apparatus;
• and
• executing a scan for an access point according to a profile on the basis of the attitude fluctuation of the apparatus.

• acquire information of a hidden access point having issued no network name from a connection candidate list of the wireless network stored in a memory;
• compare the wireless network from the name acquired by the scan and the wireless network of the hidden access point acquired from the connection candidate list in an order of priority;
• and
• execute the connection to the access point with the network name of the wireless network acquired by the scan, when the wireless network with the network name acquired by the scan has a higher priority by said comparison in the order of priority.
