Check wifi's working

lspci -k

Or for usb wifi:

dmesg | grep usbcore

... and hopefully it'll say the new interface is registered.

Check if a wifi interface has been created

ip link

iw dev

Assuming it's wlan0, bring it up with

ip link set wlan0 up

Error messages probably means your wireless chipset requires a firmware to function. In this case, check the kernel messages for firmware being loaded

dmesg | grep firmware

Utilities

iw doesn't do wpa/wpa2. wpa_supplicant does everything. iwd does everything except WEXT encryption.

Connecting

Get the link status:

iw dev wlan0 link

Scan for available points:

iw dev wlan0 scan

The connecting commands do not cover wpa2.

Fucking Hell

I really need to script this. Something like:

Auto-check wireless device.
Auto-check scan for devices and grab names
Display names
Prompt for name selection (e.g. '1').
Auto-connect to wireless associated with selection n.
Prompt for password.
Try to connect.
Ask if user wants a password copy stored in /tmp/.

Connection

This is a shitshow. Focus: netctl is the Arch project to get this going.

Okay - can't be fucked. Most of this is systemd based.
