Hi Mick,

I have te same thing when using kismet, after starting kismet if I use airmon-ng to look at my interfaces, I have this:

$ airmon-ng
wifi0           Atheros         madwifi-ng
ath0            Atheros         madwifi-ng VAP (parent: wifi0)
kis0            Atheros         madwifi-ng VAP (parent: wifi0)

Then if I want to shootdown kis0, I will use airmon-ng like this:

$ airmon-ng stop kis0

And kis0 will be destroyed.
So I think you can destroy any child of wifi0 by doing this with airmon-ng

For enabling monitor mode I do like you:

$ airmon-ng start wifi0

It will create a new child of wifi0, ath1 in my case.
Then starting 'airodump-ng ath1' will let me capture packet coming on ath1, if of course any AP are active in my
neighbourhood

To destroy ath1 you do like for destroying kis0

$ airmon-ng stop ath1

Hope it help
