Power off the computer and open the case to access an available PCI Express slot. Insert the adapter into the slot and secure it with the bracket screw, then close the case and power on the system. Install the appropriate drivers according to the operating system prompts or the manufacturer's driver package so the operating system recognises the new PCIe wireless adapter.
