Abstract: A method of accessing a wireless network and associated computer system. The computer includes a memory, a wired network media access circuit for accessing a wired network, and a wireless network media access circuit, connected to the wired network media access circuit through a specific interface, for accessing a wireless network. A transmission memory space and a receiving memory space are allocated in the memory. According to a descriptor, the wired network media access circuit can access a control data and a packet data stored in the memory space allocated in the memory. The control data is for controlling the wireless network media access circuit, and for reflecting statuses of transmission and receiving of packet data.
