That was Pierre, who started this thread. For me, I have two AR9287 cards in two almost identical laptops. For one of them (wife's), the wireless has never worked well. The other (mine) has been pretty good. Recently I swapped the wireless cards. Mine started giving all sorts of trouble, but the wife's was no better. When I upgraded from kernel 3.3.1 to 3.3.2, mine got a whole lot better, whereas the wife's didn't. I suspect there are two problems, one of which got fixed in 3.3.2. > Try looking at the xmit, interrupt, and recv ath9k debugfs files. Thanks I will. In the case the card becomes unassociated, is there a way of finding out the reason why? Mitch.
