i have my router no more than 20 feet away i have an acer aspire 5720 with the atheros 5007 wireless

i have tried the injection test it says it works fine

i done the airodump-ng etc its fine gets the AP and starts writing.

i then done the aireplay-ng -3 -b etc

its reading packets fine

when i do the aireplay-ng -1 0

it will authenticate and it will work fine but not a single IV will be collected and the data bit on airodump stays at 0 so everything works but no IVS are collected

any help appreciated!!!!
