Thank you for documenting this. I have not tested power-save mode yet. The OpenBSD clients I use do not support it. It sounds like this is something that needs more work. > Is there anything I can try to get 802.11n stable? Unless you wish to debug and fix the code yourself, it sounds like the best you can do for now is to disable power saving.
