I wasn't actually even aware of doth, but now looking at wiki, it indeed is there. As an interface level attribute it is a bit strange, though, as the channel is set at the device level. DFS support depends also on the country code, which is a device level attribute as well. I also think that 'dfs' is a more obvious name for DFS support for the casual user :P >From your trac ticket I got the impression that you were able to enable DFS even without enabling the ATH9K_DFS_CERTIFIED -configuration option. Is that really the case? Have you witnessed whether it actually changes channels? Matti
