# 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
or
> 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:
1. Auto-check wireless device.
2. Auto-check scan for devices and grab names
3. Display names
4. Prompt for name selection (e.g. '1').
5. Auto-connect to wireless associated with selection n.
6. Prompt for password.
7. Try to connect.
8. 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.
