This is basically a very new devices which received a lot of positive reviews. And linux people keep insisting that Atheros are one of the better Wifi choices to make on linux. But I'm not getting anywhere this device! I'm on the latest mainline with the newest firmware and the bleeding edge WiFi drivers and I get *frequent* connection losses and slow re-associates - and sometimes I associate but it takes minutes for routes to come up. This hasn't changed since day 1 I installed the device and went on for months. Virtually every internet page that has more than a "light textual" content renders the connection unusable. If I just leave it like that it takes a long time to get back on, usually I restart the interface which helps it reassociating a little quicker. As soon as there are several concurrent connections or just a moderate load on the device the connection fails, dmesg leaves me with nothing but: ieee80211 phy0: wlan0: No probe response from AP XX:XX:XX:XX:XX:XX after 500ms, disconnecting. cfg80211: Calling CRDA for country: CN wlan0: authenticate with XX:XX:XX:XX:XX:XX (try 1) wlan0: authenticated wlan0: associate with XX:XX:XX:XX:XX:XX (try 1) wlan0: RX AssocResp from XX:XX:XX:XX:XX:XX (capab=0x431 status=0 aid=1) wlan0: associated I'm getting a little desperate over this as it'S really frustrating. Thanks for your help
