Thanks Gustau!

For some reason I sometimes had to do ifconfig wlan0 up && sleep 2 &&
ifconfig wlan0 scan sometimes. As though it needed a moment of
initialization to scan. You also have a different RF than I have, so
anything's possible.

Unfortunately I've been very busy lately, but I can assure you that
anything that happens with ral probably won't use that code anymore.
I've been working on and off in a direct port from OpenBSD. It's become
clear that either the rt2860 mentioned by Michael or OpenBSD's ral or
(both if they are the same?) will probably be the path.

I won't get to even look at OpenBSD's ral again until a week or so from
now, but I do intend to give it another shot, I just wouldn't hold your
breath.

My recommendation is to try the code offered by Michael, it sounds as
though it is working.
