I seem to recall you created your wlan interface named "mwl_wlan0", so you need to type wlandebug -i mwl_wlan0. I saw that, but that is hardcoded to expect wlan<x> (wlan0, wlan1, etc) for an interface name. Having seen that, I recompiled wlandebug without the hardcoded interface name check and it didn't work either, but it did toss an error for the sysctl it was trying to tweak. That made me look deeper at the code and see it was really just setting the debug sysctl based on flags that wlandebug was aware of. Handy, but the same thing could be done by hand with sysctl and some bitwise math in a pinch, assuming the interface has the right oids. (Which mine doesn't, for some reason...) Jim
