As soon as I installed Ubuntu 11.04 64-bit (kernel 220.127.116.11 ) I noticed that aircrack does not work with my 2 wireless adapters Edimax 7318USg and ALFA AWUS036NH (fixed channel 1 error).
I used to get the same error since aircrack 1.0 but I fixed it installing the kernel 2.6.34. Unfortunately this kernel does not work on Ubuntu 11.04.
I tried to go back to aircrack 0.93 and it only works if I use my laptop integrate wireless card (only for WPA since the card is not able to inject). Edimax 7318USg and ALFA AWUS036NH are not compatible out of the box with aircrack 0.93. I remember I used to install drivers and play around with ubuntu 8.10 and 9.04 to make aircrack work with my Edimax 7318USg, but now I do not remember how to do it.
I have tried many patches and workaround posted on the internet but none of them has worked so far.
I hope some one will help me out because I have never had a problem making the edimax adapter work with aircrack since ubuntu 8.10.
This fixed channel 1 error is driving me crazy!
