I have been testing aircrack beta 4 and 5 with a nl-2511 and a wg511 on linux kernel 2.6.11. I find when starting airodump and aireplay -1 with my nl-2511 card it will never associate and I get "fwrite failed, no such file or directory". This only happens when I try the association attack and it happens if I start aireplay 1st then airodump or viceversa. Also, the wg511 with the same command will associate and the fwrite error is never seen. Not sure if this is a known issue or not. The nl-2511 now does the same thing with hostap driver and the wlanng driver.
