I did the above changes and rebuilt my kernel. If I do sysctl > dev.ath0.txagg=1, sc_in_scan is 0 just as expected. If I do a manual scan > right after, it is still set to 0. right. Can you check the sc_in_scan value _during_ an ifconfig wlan0 scan ? (ie, whilst it's running.) You'll have to be ninja-fast. I just want to verify that it's actually working.. > ...or was I supposed to _only_ do ifconfig wlan0 scan once the interface has > died? The above is just to verify that it's working. Once that's done, check sc_in_scan once the interface has hung. I'm testing the hypothesis that the scan logic is "hung" somehow and that is why the interface never comes out of STA power save mode.
