WiFi

Use WiFi without a separate network manager with this simple guide. Needs "dhcpcd" or "dhcpclient", "net-tools" or "iproute2", "wpa_supplicant", and the WiFi firmware for your wireless card (like "iwlwifi" and its "ucode").
NOTE: The "<DEVICE_NAME>" can be either "wlp3s0" or "wlan0". Change accordingly the following commands to suit your needs.

  • Create the configuration file (as "root", not "sudo"):
    wpa_passphrase <NETWORK_NAME> <PASSWORD> > /etc/wpa_supplicant.conf
  • Delete non hashed password from /etc/wpa_supplicant.conf

Each time you need to connect type the following command (as "root" or with "sudo"):

  • EXAMPLE 1: With "net-tools" and "dhcpcd":
    ifconfig <DEVICE_NAME> down
    ifconfig <DEVICE_NAME> up
    wpa_supplicant -B -i<DEVICE_NAME> -c /etc/wpa_supplicant.conf -Dwext
    dhcpcd <DEVICE_NAME>

  • EXAMPLE 2: With "iproute2" and "dhclient":
    ip link set <DEVICE_NAME> down
    ip link set <DEVICE_NAME> up
    wpa_supplicant -B -i<DEVICE_NAME> -c /etc/wpa_supplicant.conf -Dwext
    dhclient <DEVICE_NAME>

You can save either example in a script to activate Wi-Fi.

  • Note: As an educational tip, the name of a network is also called "SSID" in other places.
