Im trying to connect to my Wireless router but not having any luck. Could someone give me a few pointers?

skay@raspberrypi ~ $ sudo wpa_supplicant -iwlan0 -c/etc/wpa_supplica/wpa_supplicant.conf
rfkill: Cannot open RFKILL control device
ioctl[SIOCSIWENCODEEXT]: Invalid argument
ioctl[SIOCSIWENCODEEXT]: Invalid argument
wlan0: Trying to associate with xx:xx:xx:xx:xx:xx (SSID='Cerberus' freq=2462 MHz)
wlan0: Associated with 00:00:00:00:00:00
wlan0: CTRL-EVENT-DISCONNECTED bssid=xx:xx:xx:xx:xx:xx reason=0

This is my wpa_supplicants config:

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

sudo -H gedit /etc/wpa_supplicant.conf

Inside the file add the following for WPA2

        psk="ASCII PSK Password in Quotes"
        proto=RSN WPA
        pairwise=CCMP TKIP
        group=CCMP TKIP

My Example : ssid="A-B-C-D" & Password is = psk="abc12345"

Then Remove network-manager-gnome

sudo apt-get purge network-manager-gnome

Setting the Wireless Interface to Connect at Boot

sudo -H gedit /etc/rc.local

Add the following lines

ifconfig eth0 down
ifconfig wlan0 down
dhclient -r wlan0
iwconfig wlan0 essid "A-B-C-D"
iwconfig wlan0 mode Managed
ifconfig wlan0 up
dhclient wlan0

Then restart networking... I did a reboot

Note: I have already configured my router for Static IP (Reserved IP from Router) & DNS

  • Hi Insafian, thanks for the answer, Can you explain me this "ASCII PSK Password in Quotes" from the file /etc/wpa_supplicant.. Do I need wpa_passphrase of my network here? – Mujtaba Haider Nov 13 '13 at 3:34
