Wi-Fi-driver lifecycle reference
How wireless adapter identity, radio management, network interfaces, and package metadata relate without collapsing them into one layer.
Wireless is a layered identity
A Wi-Fi adapter has a host-side device identity and a network interface identity, while its radio and firmware handle wireless-medium behavior. A wireless network name is a property of a network environment, not the identity of the adapter or its package.
Driver and firmware meet
The host driver exchanges commands and data with adapter hardware and may coordinate with firmware that runs on the device. Their release records, trust boundaries, and responsibilities can differ even when a vendor publishes them together.
From radio to interface
Association, link properties, packet handling, and host interface state belong to different parts of the stack. A driver can expose capabilities and state to the network stack without owning every policy or protocol above it.
Package records describe scope
A wireless package can declare supported hardware identifiers, platform architectures, radio features, and related services. A version number should be read alongside those declarations rather than interpreted as a universal statement about all wireless behavior.

Questions and answers
Is a Wi-Fi network name a driver identifier?
No. It identifies a network service or access point context, while the adapter and package have separate identities.
Does a wireless driver include the radio firmware?
Not necessarily. Firmware is device-resident code with a distinct lifecycle, even when a package coordinates with it.
Why distinguish link state from interface state?
The interface is a host-software representation; link state describes properties of the wireless medium. They can change independently.
