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 
country=GB 
update_config=1


network={
    ssid="noname"
    #psk="zong4gisbest"
    psk=ead5b0b7e82e1a68f01e9a17a2a7719ec24575c89bb5b5805e4ae49c80daa983 }

Here are the results of my commands on Raspbian

iwconfig

wlan0     unassociated  Nickname:"<WIFI@REALTEK>"
          Mode:Auto  Frequency=2.412 GHz  Access Point: Not-Associated
          Sensitivity:0/0

Answer

Edit your wpa_supplicant.conf , change the following lines:

network={
    ssid "noname"
    psk"zong4gisbest"

to:

network={
    ssid="noname"
    #psk="zong4gisbest"
    psk=ead5b0b7e82e1a68f01e9a17a2a7719ec24575c89bb5b5805e4ae49c80daa983
}

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
