Can't Put My Network Card into Monitor Mode

Ok...I'm using Kali 2.0. A few days ago, in an attempt to hack an asshole neighbor's Wifi password, airmon-ng gave me rage quit. Instead of putting my wifi card into mon0 and wlan0 seperated, it put my card into wlan0mon! airodump-ng couldn't recognize it and...you get the idea. Can't kill it, either. airmon-ng said that I was attempting to kill something that wasn't monitor mode and blah blah blah. I looked up the Internet and the result were quite disappointing. Can anyone help me with that issue? I would be very thankful
