I am trying to monitor wireless on Broadcom BCM43227, I used sudo airmon-ng to run the monitoring, i get command not found. I installed kismet, when i run, i get this

*uttam@UT:~$ sudo kismet Launching kismet_server: //usr/bin/kismet_server Suid priv-dropping disabled. This may not be secure. No specific sources given to be enabled, all will be enabled. Non-RFMon VAPs will be destroyed on multi-vap interfaces (ie, madwifi-ng) Enabling channel hopping. Enabling channel splitting. NOTICE: Disabling channel hopping, no enabled sources are able to change channel. Source 0 (addme): Opening none source interface none... FATAL: Please configure at least one packet source. Kismet will not function if no packet sources are defined in kismet.conf or on the command line. Please read the README for more information about configuring Kismet. Kismet exiting. Done. uttam@UT:~$*

I did check a blog about kismet on Broadcom that says about some binary drivers not allowing to do it...

I used iwconfig and it says no extension : what is that

well I need to give a hand on air monitoring............ help, how to do it
