VAP destroyed/ ERROR while getting interface flags: No such device

[fnderguitarist]

So I'm trying to do a WEP crack and I'm getting the error message:
"ERROR while getting interface flags: No such device"
Here's what I've been entering into the Shell-

bt ~ # airmon-ng

Interface Chipset Driver
wifi0 Atheros madwifi-ng
ath0 Atheros madwifi-ng VAP (parent: wifi0)


bt ~ # airmon-ng stop ath0

Interface Chipset Driver
wifi0 Atheros madwifi-ng
ath0 Atheros madwifi-ng VAP (parent: wifi0) (VAP destroyed)

bt ~ # ifconfig ath0 down
ath0: ERROR while getting interface flags: No such device


Can someone explain to me what I am doing wrong?

ath0: ERROR while getting interface flags: No such device

Isn't this error message self-explanatory? You try to put an interface ath0 down that does not even exist as you destroyed it in the previous step!

Not sure what you'd like to do (this is not obvious), but if you'd like to have an interface ath0 in monitor mode to work upon, I'd try (assumed you have one ath0 NOT in monitor mode before)

# wlanconfig ath0 destroy
# wlanconfig ath0 create wlandev wifi0 wlanmode monitor
