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. Matt
