ok , that aireplay-ng -9 wlan0 command seemed to indicated that the injection drivers are working.

i disabled mac security on my router and selected a random mac address for my n900 via the gui.

i was able to authenicate without a problem which confirmed mac security was off.

but my injection screen still shows no packets sent and no arps received. it took 15 minutes to collect 14 iv's, so 5k iv's seems a long way off!

does everyone else's screen show packets being sent?

my router is only a few days old, so it may defend against this kind of attack, so the f/aireplay show seems over before it's begun..
