Just so you know, that aspect of the system (drivers) is beyond the skill set that I am willing to provide insight into. Perhaps someone else will help you out but I, unfortunately, can not.
Once you've got the --test working, you should be able to test yourself against WEP with no issue (and WPA de-authing). In the meantime, you can just hold out with an airodump-ng session running - on a moderately trafficked network you're going to need roughly 3 days worth of solid capturing to get enough IV's - the arp replay attack is just to speed things along significantly.
A good time to read through the entire set of documentation I should think.
