Title:
  168c:0032 [Asus G75VX] Slow wireless with AR9485 ath9k

Status in The Linux Kernel:
  Unknown
Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  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.
