Wireless network cards for computers require control software to make them function (firmware, device drivers).This is a list of the status of some open-source drivers for 802.11 wireless network cards.
Wi-Fi microcontrollers enable Wi-Fi connectivity for devices so that they can send & receive data and accept commands. As such, Wi-Fi microcontrollers can be used for bringing otherwise ordinary devices into the realm of the Internet of things. Wi-Fi microcontroller chips:

IEEE 802.11ac-2013 or 802.11ac is a wireless networking standard in the IEEE 802.11 set of protocols (which is part of the Wi-Fi networking family), providing high-throughput wireless local area networks (WLANs) on the 5 GHz band. [d] The standard has been retroactively labelled as Wi-Fi 5 by Wi-Fi Alliance. [9] [10]
Wi-Fi 6, or IEEE 802.11ax, is an IEEE standard from the Wi-Fi Alliance, for wireless networks . It operates in the 2.4 GHz and 5 GHz bands, [ 9 ] with an extended version, Wi-Fi 6E , that adds the 6 GHz band. [ 10 ]
A wireless network interface controller (WNIC) is a network interface controller which connects to a wireless network, such as Wi-Fi, Bluetooth, or LTE (4G) or 5G rather than a wired network, such as an Ethernet network. A WNIC, just like other NICs, works on the layers 1 and 2 of the OSI model and uses an antenna to communicate via radio waves
^A In the 2.4 GHz bands bonded 40 MHz channels are uniquely named by the primary and secondary 20 MHz channels, e.g. 9+13. In the 5 GHz bands they are denoted by the center of the wider band and the primary 20 MHz channel e.g. 42[40] ^B In the US, 802.11 operation on channels 12 and 13 is allowed under low power conditions.
