airmon-ng = no interface after macchanger

[richtfunk]

I have that hardware:
http://www.backtrack-linux.org/forum...supported.html

which worked perfect with Linux Mint (my main system) and BT. I tried to use BT for my Wifi and did changed the mac-address. I can't see the interface any more with airmon-ng. Can I somehow reset the adapter?

What commands are you using ? It's pretty hard to help you out, if we have to guess that ...

[richtfunk]

I'm using

airmon-ng

as written in the headline. I can remember to have seen an interface there the 1st time, but there is none now. It says only the head of the list: "Interface Chipset Driver" but nothing else. It's empty.

ifconfig

gives me "eth0" which is the wire and "lo" loopback. I guess there should be wlan0 listed as well?

Are you running Backtrack inside VMware/VBox ?

[richtfunk]

Yep, but the wifi-adapter worked before within Vbox as well. It doesn't work in Vbox (BT/XP) and on a real system (Mint).

[sickness]

Try plugging the adapter out than connect it back to the VM.

[richtfunk]

Still same problem.
How can I reset the hardware? Maybe the Firmware is looking for a certain MAC-address and can't initialize itself?
On XP I can, at least, see the hardware but its got the problem which tells me that the adapter can't be activated.

The adapter worked fine before with all systems.

'lsusb' gives me:
Bus 001 Device 003: ID 0cf3:9271 Atheros Communications, Inc.
Bus 001 Device 002: ID 0cf3:9271 Atheros Communications, Inc.
don't know why 2 devices(?) but it can see the Hardware itself and it is obviously somehow running but:

root@bt:~# dmesg | grep ath

I can't interpret the problem :-(

Could you please post the exact commands you are using in sequential order. It may also be helpful if you told us what network card you are using.
Last I knew macchanger needed to bring the interface down then it could change the hard coded mac address.
You will need to do something like this:

ifconfig wlan0 down
macchanger -r wlan0
ifconfig wlan0 up
airmon-ng start mon0

All commands I just typed were off the top of my head and I may have made a mistake but you should get the idea.

[richtfunk]

As defined in post #1 my network card is the WN722N.

Again, I plug in my hardware, I can see the hardware with

lsusb

but I DON'T have an interface wlan0 or wlanx. The interface-list is empty.

Yesterday I posted a comment with

dmesg

. I hope it will be online soon. It tells me I have to wait for the admin to check my comments and it usually takes 1 or 2 days.
