[PROBLEM] Wifi Issue

[abhiroopd]

I switched from Volumio actually, and it was working fine there, and I just verified the password once again.
When I go to raspi-config, system options -> wireless LAN, I get the following error message: 

Code:

Could not communicate with wpa_supplicant. There was an error running option S1 Wireless LAN

And then I tried the following commands - 

Code:

pi@moode:~ $ sudo killall wpa_supplicant
pi@moode:~ $ sudo wpa_supplicant -c/etc/wpa_supplicant/wpa_supplicant.conf -iwlan0
Successfully initialized wpa_supplicant
