Hy there, I am having problem in connecting my raspberry pi to a wifi dongle. I have followed a lot of tutorials from internet but no success so far.

My WIFI dongle can scan the networks but it's not connecting to any network.Here is what my configuration file looks like

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev 

    psk=ead5b0b7e82e1a68f01e9a17a2a7719ec24575c89bb5b5805e4ae49c80daa983 }

Here are the results of my commands on Raspbian


wlan0     unassociated  Nickname:"<WIFI@REALTEK>"
          Mode:Auto  Frequency=2.412 GHz  Access Point: Not-Associated
          Retry:off   RTS thr:off   Fragment thr:off
          Power Management:off
          Link Quality:0  Signal level:0  Noise level:0
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

eth0      no wireless extensions.

lo        no wireless extensions.

Edit your wpa_supplicant.conf , change the following lines:

    ssid "noname"



save then run

wpa_supplicant -iwlan0 -D wext -c/etc/wpa_supplicant/wpa_supplicant.conf -B
dhclient wlan0

The error:

nl80211: Driver does not support authentication/association or connect commands

mean that the standard nl80211 doesn't support your device , you should use the old driver wext.

To correctly set up your wpa_supplicant.conf , it is better to use the wpa_passphrase command:

wpa_passphrase YOUR-SSID YOUR-PASSWORD >> /etc/wpa_supplicant/wpa_supplicant.conf

To automatically connect to your AP after restart edit the wlan0 interface on your /etc/network/interfaces as follow:

allow-hotplug wlan0
iface wlan0 inet dhcp
    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
  • Tried using wpa_passphrase YOUR-SSID YOUR-PASSWORD >> /etc/wpa_supplicant/wpa_supplicant.conf But here is the error imgur.com/a/TudGH Oct 24, 2017 at 10:27
  • after saving, when i tried>>wpa_supplicant -iwlan0 -c/etc/wpa_supplicant/wpa_supplicant.conf -B I see this error now imgur.com/a/wrDrh Oct 24, 2017 at 10:30

    Hey bro, it just worked. I thought, you asked me to use two different commands 1>>wpa_supplicant -iwlan0 -D wext -c/etc/wpa_supplicant/wpa_supplicant.conf -B 2>>dhclient wlan0 I didn't know that it's a single command. Now it worked great. I am doing ssh using wifi now. thanks bro Oct 24, 2017 at 12:30
