A wireless NIC enables a computer to connect to a wireless network. Wireless NICs use PCI and PCIe expansion slots on the motherboard. Some wireless NICs are installed externally with a USB connector.
To install a wireless NIC, follow these steps:
Step 1. Align the wireless NIC to the appropriate expansion slot on the motherboard.
Step 2. Press down gently on the wireless NIC until the card is fully seated.
Step 3. Secure the wireless NIC mounting bracket to the case with the appropriate screw.
