Can you try these and post the log ? Will do. The second one did not apply though. You have a line: if (!(sc->hw->conf.flags & IEEE80211_CONF_OFFCHANNEL) && start) { While my kernel has: if (!(sc->sc_flags & (SC_OP_OFFCHANNEL)) && start) { I've manually added your code below it and will test with that unless you shout no quickly. > If you are willing to move to a more recent kernel, then current > wireless-testing would be a good choice since it has various driver fixes. > There are a few pending ath9k patches which have not been merged yet, you > can find it here: > > http://sujith.github.com/patches/wl/wl-ath9k-May-29-2012.patch I can do that, but ideally I need to find a set of fixes which will make a released kernel work. compat-wireless also works for us. I'll test the above patches first and then we'll see.
