Laptop Wi-Fi and network driver reference
The adapter, radio, firmware, network interface, and package layers behind laptop wireless connectivity.
The laptop adapter has several identities
A wireless adapter can have a bus identity, radio or firmware identity, network-interface identity, and package identity. A network name belongs to the surrounding wireless environment, not to the laptop driver. Keeping those nouns separate makes the reference portable across internal and external adapters.
Power and platform matter
Laptop wireless components participate in platform power states, antenna or radio controls, firmware communication, and network stack interfaces. Those relationships can be represented by drivers, firmware, services, and policy. No one friendly name describes the full path.
Interface and link are distinct
Host software exposes a network interface with properties and state, while the wireless medium has its own link and association records. Packet handling, radio state, and application communication are related but belong to different layers.
Package scope is declared
A package can identify supported hardware, platform architecture, radio capabilities, and companion components. A version field should be read within that declared scope rather than used as a universal statement about all laptop networking.

Questions and answers
Is a wireless network name part of the laptop package?
No. It identifies a network environment; the adapter and package have separate identities.
Does the Wi-Fi driver contain radio firmware?
Not necessarily. Firmware is device-resident code with a separate lifecycle, even when a host package coordinates with it.
Why separate interface state from link state?
The interface is a host-software abstraction, while link state describes a wireless-medium relationship.
