I just wanted to try out how to connect to my WIFI WPA2 via terminal.

Therefore I created "/etc/wpa_supplicant"

network = { 
  ssid = "nameOfWifi"
  psk = "passwordNumberThatIFoundOnTheWifiHardware"
}

Then I started following command

sudo wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant.conf -D nl89211

No Errors thrown. Up to the last step

Launching command to connect to my Wifi now

sudo dhclient -v wlan0

Output:

//Meta infos...
Listening on LPF/wlan0/00:1e:65:bb:4e:ee
Sending on LPF/wlan0/00:1e:65:bb:4e:ee
Sending on Socket/fallback

DHCPDISCOVER on wlan0 to 255.255.255.255 port 97 interval 3 (xid:0x18018e53)
DHCPDISCOVER on wlan0 to 255.255.255.255 port 97 interval 4 (xid:0x18018e53)
DHCPDISCOVER on wlan0 to 255.255.255.255 port 97 interval 5 (xid:0x18018e53)
//repeating

What do I miss here? If there're wrong credentials - how can I figure out some error message for that case? Is there a more detailed debug/verbose?

You need to use wpa_passphrase when creating a configuration file for a WPA network. wpa_passphrase is included with the wpa_supplicant package.

Example: wpa_passphrase "nameOfWifi" "password" > /etc/wpa_supplicant.conf

  • Thanks you made my day! Wasn't aware that my psk is a generated passsword - just thought its the plain password I enter when I use the GUI aswell :D

  • You are welcome :) Before the GUI sends your password to a WPA network, it actually encrypts it also!
