Wireless NIC (Wifi / Bluetooth)
In order for a device to connect wirelessly to a network it must use a wireless network interface card. The industry standard is through the use of a WiFi NIC, though it is also possible to connect using Bluetooth to some networks.
Most modern portable devices such as mobile phones, tablets and laptops contain a built-in wireless NIC.
Desktop computers don’t always come with a built-in wifi NIC so you might need to install one.
