** Description changed:
With the latest raring kernel image (linux-signed-image-3.8.0-18-generic) my
wireless connection becomes very slow after a few minutes (ping to my AP
increases from < 1ms to ~ 900ms).
Kernel 3.8.0.17.27 is still fine, other wireless devices continue to work
fine if the problem occurs.
HW is AR9485 (ath9k) 1x1 802.11n in Asus G75VX laptop, AP is Asus RT-AC66U.
