Hello.I am using Kali Linux Sana in my hp af006ax notebook.I was fascinated in trying the aircrack-ng for my wireless access point.It shows wireless extension for wlan0. My wireless chipset is Realtek 8723be. Everything works fine.I can put my card in monitor mode.But when I run airodump-ng command it shows nothing. Even in wifi network manager it shows no networks. First I thought its a driver problem. But it shows drivers are installed. When I keep my laptop just next to the router then it shows fair signal strength in network manager. It doesnt show distant networks.Please look forward to this issue.
