Hi, After 2 days of testing with ifconfig ath0_wlan0 -ampdutx I must say that the situation has not improved. The system is running exactly the same way like before which regards the stability. I have a lot of stuck beacon messages as well. When normally WiFi is not working then from my laptop I can see the ssid, I can connect (but it always connect with 15mbps) and disconnect from it but by pinging the router I am not receiving reply. I think the WiFi became unstable after I generate a heavy traffic by my torrent client from my laptop.
