Wifi setup on Arch Linux

The following steps are showing how I did setup my wireless connection with an static IP on my ArchLinux driven RaspberryPi. You need to have installed sudo to uses this instructions:

  1. Update all packages:
    $> sudo pacman -Syu
  2. Install dialog package:
    $> sudo pacman -S dialog
  3. Install wpa_supplicant package
    $> sudo pacman -S wpa_supplicant
  4. Run wifi-menu:
    $> sudo wifi-menu -o

    This will start the Wifi-Setup dialog.

  5. Select your network:

  8. The dialog will close automatically.
  9. Edit the generated config file (/etc/netctl/YOUR-ENTERED-PROFILE-NAME):
    $> sudo nano /etc/netctl/wlan0-Valhalla
  10. Set IP-type static, IP-Address, Gateway and DNS server like this:
    Description='Valhalla at home'
    Interface=wlan0
    Connection=wireless
    Security=wpa
    ESSID=Valhalla
    IP=static
    Key=\"aaddggeeejjenneggtssskkkekddwsdsaduawvwddvgvdgvasdg
    Address=('192.168.1.4/24')
    Gateway=('192.168.1.4')
    DNS=('192.168.1.1')
    

    The relevant lines are:
    – IP=static
    – Address=(‘192.168.1.4/24’)
    – Gateway=(‘192.168.1.4’)
    – DNS=(‘192.168.1.1’)

  11. Now you can enable the profile, so that your pi starts with it:
    $> sudo netctl enable wlan0-Valhalla
    $> sudo netctl start wlan0-Valhalla
  12. Reboot the system:
    $> sudo reboot
