Having problems with Airmon/Backtrack etc

[Gel]

I managed to locate and crack two wep keys two nights ago with Backtrack 2 and my laptop (built in Atheros)

Last night went to do it though, same equipment, same conditions and nothing, zip, nadda, not a bean, even tried Backtrack 3 also...as it's a live CD that doesn't change I find it odd?

Anyway, here is the experience so far:

Firstly, proof of signal (Sky is my one)



Attempt with Backtrack 3, I get this far:

Airmon-ng stop ath0
Airmon-ng start wifi0 9
iwconfig
(Problem - Access point not associated....but it did every time the previous night)



On to Backtrack 3

Airmon-ng stop ath0
Airmon-ng start wifio 9
iwconfig



Then I type:

airodump-ng -c 9 --bssid 00:16:CF:5B:95:3B -w output ath0
(My guide actually uses the bssid 00:14:6C:7E:40:80 but I tried that too)

I also tried leaving out {-c 9} but to no avail

This is all I get, left it overnight and absolutely nothing so something is wrong somewhere, I just can't figure it out and I'm a new one to linux also.



If anyone can help that would be great.

ON BT3 I use the following

airmon-ng start wlan0
airodump-ng wlan0

take wep essid from the above and stick into

wesside-ng -i wlan0 -v <essid>

My old thinkpad t23 usually takes a few minutes if the signal is good.

I don't use iwconfig

I'll just have to wait for my card to turn up for the PC along with the high gain aerial, laptop doesn't want to know although Driftnet is providing no end of amusement

Cheers for the help
