[Mirzet Kadic]

System: 12.04 x64 and up-to-date
Effected Hardware: USB D-Link System DWA-160 802.11abgn Xtreme N Dual Band Adapter(rev.A2) [Atheros AR9170+AR9104]

All couple of hours I loosing my wifi connection. A re-connection takes place automatically.

I can confirm that this problem is effected by this usb-wlan-stick because I have an other PC with a PCI-Wlan-Card with an other chip and I had replaced the both interfaces. The problem is always there where I using this usb-wlan stick.
