I followed the same steps in this Adafruit Wi-Fi Setup but I am not Getting Connection in Pi

This is output during lsusb and iwlist scan

    lo        Interface doesn't support scanning.

    eth0      Interface doesn't support scanning.

enter image description here

This is /etc/network/interfaces

auto lo
 iface lo inet loopback
 iface eth0 inet dhcp

 allow-hotplug wlan0
auto wlan0

 iface wlan0 inet dhcp
        wpa-ssid "SSID"
        wpa-psk "PASSWORD"

And Also I tried Like this Post wifi setup for multiple networks 2nd answer i.e USER ppumkin's answer

It is showing the Wi-fi Connection when I

sudo wicd-curses 

Even I Configured the Same Way, but When I click "C" it is disconnecting From LAN As Specified By [USER]ppumkin, but It is not Connecting to Wi-Fi. enter image description here

I am Checking it with a webserver.. I've Installed Apache In Pi. Using Wired Network I will Get Index.Html but with Wi-Fi I am Not Getting the Index Page

  • What does dmesg report for the wifi dongle? The contents of /etc/network/interfaces would probably be useful.

  • @joan I have added the /etc/network/interface... I've Removed My SSID and Password

  • See what dmesg says when the dongle is plugged in. So remove the dongle, wait a couple of seconds, reinsert the dongle. Have a look at the last few lines of the dmesg command output. What does it have to say about the dongle?

I think that, like most of us, you have ended up with a confused set of configuration statements. I expect you've fixed it by now, but others may find this useful. This assumes a modern WPA2 setup.

/etc/wpa_supplicant/wpa_supplicant.conf should be:


For an older system proto could be WPA and pairwise could be TKIP. Then in /etc/network/interfaces

auto lo
iface lo inet loopback
iface eth0 inet dhcp
allow-hotplug wlan0
iface wlan0 inet dhcp
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
iface default inet dhcp
