i want to post about my test with BT3beta and Alfa 500mw

when i run the backtrack 3 beta on my old Dell Latitude D400

it works great and the alfa works just great...inject/deauth/connecting to wep encrypted APs all is working very well

but when i run BT3beta on my new acer aspire 2920 it will catch the alfa but inject + connecting to the encrypted wep access points is just giving error

maybe something with the usb drivers of the laptop

thats it for now
