A method for switching access points of a wireless network via sharing communications is disclosed. A host computer and a client computer are connected to a first wireless network by a first communication system. The host computer determines a communication quality to the first wireless network. If the communication quality falls below a predetermined value, the host computer connects to a second wireless network to shift to a sharing communication mode to connect the client computer to the second wireless network. The host computer that has shifted to the sharing communication mode then connects to the client computer by a second communication system to connect the client to the second wireless network.

A method for switching connections between an IP-only phone and a soft phone to an IP gateway server is disclosed. An identical telephone number is allocated to the IP-only phone and the soft phone. When the soft phone has been moved such that a connection destination to a local-area network changes from a first connector to a second connector, a relay device is also changed from a first relay device to a second relay device. After recognizing its present position by a MAC address of the relay device to which it is currently connected, the soft phone issues a request to an IP gateway server to change an IP address to the soft phone when it is determined that the soft phone is located far away from the IP-only phone. When it is determined that the soft phone is located near the IP-only phone, the soft phone issues a request to the IP gateway server so that the IP address is changed to the IP-only phone.

A wireless station that includes an access point apparatus detection section which detects a usable access point apparatus from among a plurality of access point apparatuses; an allowance area calculation section which calculates an allowance area according to received signal strength indicator, frequency, and frequency bandwidth of a radio wave transmitted by a rogue access point apparatus whose frequency bandwidth overlaps with that of the usable access point apparatus, as well as according to received signal strength indicator, frequency, and frequency bandwidth of a radio wave transmitted by the usable access point apparatus; and an access point apparatus selection section which selects one access point apparatus based on the allowance area.

A System and Method provides for a connection to a predetermined access point in an optimal time even when a network name of the access point is hidden. A computer apparatus comprises a connection list table for storing the identification information of a wireless network and the information indicating that the access point for connection to the network is a 'hidden access point' having not issued the identification information in association with the identification information, and an access point switching software for confirming the connection by trying an actual connection to the 'hidden access point' after getting the information from the connection list table, and for acquiring the predetermined identification information by scanning the identification information for designating a connection partner.

Wireless network connection system and method

A portable notebook PC comprising a lid is able to avoid possible trouble during its transfer (as when a user carries the PC with him or her) and is able to reduce the time required to start up after the transfer. The portable notebook PC has a normal operating mode in which a user can utilize the notebook PC, a power saving mode in which an operation performed in the normal operating mode is saved to a predetermined memory so that power consumption can be reduced by using the minimum power required to retain data, and a transfer mode in which the system is temporarily disabled by stopping functions that may become defective during the transfer with a CPU remaining operative.

A method for controlling an external storage device connected to a computer by accepting an operation by a user and issuing an ejection request to the external storage device connected to the computer, including encryption techniques, is provided.

Method for data protection for removable recording medium

A system for controlling an external storage device connected to a computer by accepting an operation by a user via an acceptance means and encryption means for encrypting a predetermined data file stored in the external storage device, upon a particular event, is provided, is provided.
