I made a test with v3.11-rc5-saucy:

# md5sum linux-*
ecb40827ad3979c503cc0c2d1972317e  linux-headers-3.11.0-031100rc5_3.11.0-031100rc5.201308112135_all.deb
fee51a20890c8f040ad5cf8f9b34cfc1  linux-headers-3.11.0-031100rc5-generic_3.11.0-031100rc5.201308112135_amd64.deb
1e8feff839613a7ecee2ed6d2ea8e722  linux-image-3.11.0-031100rc5-generic_3.11.0-031100rc5.201308112135_amd64.deb
#

The problem is still exists.

One question: If i upgrade to 13.04, then i must open a new bug ID, or
can continue with this?

Title:
  168c:002b Atheros AR9285 Wireless on Ubuntu 12.10 is slow, unstable
  and has a weak signal.

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:

  room0: here is my AP
  room1: there is one wall between room0 and room1
  room2: there is two wall between room0 and room2

  If i use my new Lenovo G580 (Atheros 9285) with Windows 8  or my old
  notebook (HP NX6310 (Broadcom wifi) with Kubuntu 8.04 ) the signal is
  stable in every room.

  If i use my new Lenovo G580 with Ubuntu 12.10:
  room0: no problem good signal
  room1: poor signal, signal lost very frequantly

  I probe the kernel from http://ppa.launchpad.net/canonical-kernel-
  team/ppa/ubuntu too. But the problem still exist.
