I confirm unstable work of AR9285: 04:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01)
Tested on clean air environments with high quality signals on access points from different manufacturers including mikrotik, cisco and even d-link equipped with atheros/realtek and other wlan modules. Currently: The strange thing is that somehow i often see the picture when ping is extremely unstable without any logical reasons, after few minutes of work it goes up to 2k miliseconds while logs keep silence and test from another laptops and mobile phones show that everything should be fine. I always had some problems related to stability of ar9285 work but current symptoms make it impossible to continue to work with it. I will try to get bleeding-edge compat-wireless and to build ath9k module with btcoex disabled, but it will take some time for me. By the way if i remember well current symptoms appeared after kernel update.
