Any clue on by when the 802.11n support in FreeBSD will be > available for Athero's chipset? Hi, The main thing that's left is TX aggregation. Everything else (especially surrounding powersave) isn't on my personal radar at the moment. The only answer I can give you for TX aggregation is "when someone's coded it." :-) I'm going to sit down now and try to fix the TX path a bit. A bunch of stuff is needed before TX aggregation is possible (mostly surrounding implementing per-TID software TX queues, handling hardware-filtered packets and software TX retries.) I've created a new branch in FreeBSD SVN for the initial tidying up I'm doing. If you'd like to help out then please contact me privately and we can discuss how to break down the work. :) Thanks, Adrian
