Hmm.. and the wireless card always appears on? Assuming the firmware isn't buggy (did you update it recently? have you booted other OSes, i.e. Windows or Linux that could be updating the firmware automatically on load?), it should keep the light for the wireless NIC properly lit. > Any particular commit you think I should try to back out? Not in particular (in fact if_bwn has been untouched after 9.0-BETA1 was cut), but as Adrian suggested you should bisect the source of failure.. it would be a wise idea to load if_bwn as a module after boot to see if the behavior persists; next I would try out a revision sometime between r222218 (9.0 Beta1) and your head revision. Some commits of interest that you might want to try backing out and testing are: - 224717 - 225139 HTH, -Garrett
