## Introduction to Wireless devices

by the two important requirements, first by using `rfkill` (util-linux) and also
if the module of the device is currently well and complete supported hardware.
## Setup wireless on alpine Alpine Linux
## Wifi status on Alpine linux
AS any tech piece, we have hardware and software, this document only will cover
the software part, cos hardware support depends of the available modules and
reverse ingeniering that the linux community can made to the hardware.
As any tech piece, we have hardware and software, so then a "wifi setup" is made by two parts:
So then a "wifi setup" is made by two parts:
* the module manager from kernel .. (like compiling rtl8192eu-linux or r8169)
* hardware as the module manager from kernel .. (like compiling rtl8192eu-linux or r8169)
* and the software interface.. (like installing wpa_supplicant or iwd programs)
Most linux setup just configure `network-manager` package that oversimplified the things,
console setup it bit complicated but easyle covered, currently there is two options for,
the `wpa_supplicant` and the newer `iwd` from Intel, this last with less usage cases.

The `iwd` packages exits since 3.10 but only since 3.15 has support for right
autentications protocols. The package `networkmanager` and his applet are since 3.6 but
only working applet was noted since Alpine 3.12 due right setup of permissions.
> **Note** the `networkmanager` and `connman` packages has wifi management but
are only fronend interfaces and will relies over the `iwd` or `wpa_supplicant`.
Curently `iwd` aims to be the future of linux wireless, but such package needs dbus,
ironcally so how stupid is development, such pacakge is not in all install isos when
release it, if you in such stage dont have connection, so, how you can grab a complex set
of packages due dbus dependencies that apart still have a short (almost married)
relation with shitstemd?.
Also a key: `iwd` its pretty **still BAD for general purposes, its pretyy great
for normal common desktops and laptops, but bad for vaste rest of use cases,

the mayor feature of alpine is the mayor problem, minimalist and simplicity.
# Configuration of the wifi
Due the huge problem that represent the hardware, we only will covert software interface,
and we will assume you already have the modules already compiled into the kernel.
and we will assume you already have the modules already compiled into the kernel,
nowadays this is easily handled by installing the firmware packages and only few devices too
recents represents minor problems, such instalation is partialy covered as necesary.
**IMPORTANT** if in our telegram channel you called "driver" to a module kernel, you
will be punished.. **a driver is a person that drive a car! and a folder it to put papers in it, not a directory, ok?**
