While debugging recent wireless problems, I gave the aircrack suite a

Thanks Maxim!
How about this patch to fix this issue:
I will definitely find some testers, the problem is that I have been
unable to reliably reproduce the "channel -1". Since I don't know the
exact conditions this happens under the best I can do is have a few
people test it and make sure no one sees the error.
Mister_X, how does this look to you? I assume you are familiar with the
issue.
Thanks,
Rick Farina
