A computer peripheral device wireless linking method and system is proposed, which is designed for use in conjunction with a wireless peripheral device and a computer platform for the wireless peripheral device to be linkable via an access-point device to the computer platform; and which is characterized by the use of a wireless LAN searching and linking technology for the wireless peripheral device to be linked via the access-point device to the computer platform without having to use Ethernet ports, input devices, and monitor screens as in the case of prior art. This feature allows the wireless peripheral device to be linked to the computer platform with an instant play capability, such that the use of the wireless peripheral device is more convenient.
