** Package changed: linux-signed (Ubuntu) => linux (Ubuntu)
** Changed in: linux (Ubuntu)
Status: Confirmed => Incomplete
** Summary changed:
- 168c:0032 Slow wireless with AR9485 ath9k
+ 168c:0032 [Asus G75VX] Slow wireless with AR9485 ath9k
** Tags added: needs-wifi-debug
** 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.
