I have a dell vostro 1014 Laptop, which runs a ubuntu 12.04. My wireless is enabled, but the LED doesnt glow and its also unable to find the connections nearby. When i was trying to sort out this issue with RTC, someone told me that it is an "rfkill soft-off" issue. Previously, someone told me that there are many interfaces created which is creating a problem for wifi. i am not sure, what that meant. Anyway, thats all i know about the problem. my wireless driver is an AR9285, by Atheros Communication Inc. Help me out guys!!
