9. The method in accordance with claim 8 , wherein said first and third wireless devices transmit the random number to said second and fourth wireless device, respectively, as well as the identification information.

10. A method for establishing a wireless connection between a first wireless device provided in a first computer and a second wireless device, and between a third wireless device provided in a second computer which is different from the first computer and a fourth wireless device which is different from the second wireless device, said method comprising the steps of:

receiving a first group information that identifies said first wireless device in the first wireless device and setting the first group information for said first wireless device;

receiving a second group information that identifies said third wireless device in the third wireless device and is different from the first group information and setting the second group information for said third wireless device;

setting the first group information for said second wireless device;

setting the second group information for said fourth wireless device;

receiving identification information that identifies said second and fourth wireless devices with the first and second group information set in the first and third wireless devices, respectively, the identification information is identical in said second and fourth wireless devices;

setting the identification information for said second wireless device;

setting the identification information for said fourth wireless device

using the first group information and the identification information to specify said second wireless device to establish the wireless connection between said first and second wireless devices; and

using the second group information and the identification information to specify said fourth wireless device to establish the wireless connection between said third and fourth wireless devices.

11. A system for establishing a wireless connection between a first wireless device provided in a first computer and a second wireless device and between a third wireless device provided in a second computer which is different from the first computer and a fourth wireless device which is different from the second wireless device, said system comprising:

a first group information creating circuit for creating a first group information that identifies said first wireless device;

a second group information creating circuit for creating a second group information that identifies said third wireless device and is different from the first group information;

first and second storages for storing the first and second group information, respectively;

identification information creating circuits for creating identification information that identifies said second and fourth wireless devices, the identification information is identical in said second and fourth wireless devices;

third storage for storing the first group information and identification information; and

a fourth storage for storing the second group information and identification information,

the first group information and the identification information being used to specify said second wireless device to be wirelessly connected to said first wireless device to establish the wireless connection between said first and second devices, and the second group information and the identification information being used to specify said fourth wireless device to be wirelessly connected to said third wireless device to establish the wireless connection between said third and fourth devices.

12. The system in accordance with claim 11 , wherein the first and second group information is set at a startup of said first and third wireless devices, respectively.

13. The system in accordance with claim 11 , further comprising a first transmitter for transmitting the first group information and the identification information to said second wireless device to have said second wireless device set the first group information; and
