I can confirm that this bug still exists and have therefore put the
status back to incomplete. I've been experiencing it day in and out (to
my great frustration) for the past 18 months or so. The behavior is
consistent across maybe 2 dozen wifi networks in equally many locations.

My wifi range and stability is still many times better in Windows than
it is in Kubuntu Linux (this is a dualboot system). In many places like
public libraries, where the laptop can be quite far from the actual wifi
receiver, I still have good signal and multi-MB/s download speeds in
windows while in ubuntu I cannot see the network, cannot connect to the
network or sometimes can connect but it drops every minute or so.

If I sit right next to a wifi receiver I have an excellent and
uninterrupted connection for hours on end, so I'm quite convinced that
generally speaking, the driver works well, but that the problem is
simply a much more limited range (transmission power?) than in windows.

I'm running Kubuntu Linux 13.10 with kernel 3.11.0-18-generic. 
My laptop is a Lenovo b570e. 

I hope that this bug will eventually get fixed, as I still prefer Linux
as an OS but find myself needing to switch to Windows in most public
locations or being the weirdy who insists on running an ethernet cable
across the room because I don't have decent wifi in Linux :-/

If there is anything I can do to assist in fixing this bug, just let me
know! I'd really to help this get solved but I'm completely unfamiliar
with linux/kernel/driver programming.

Title:
  Atheros AR9285 Wireless on Ubuntu 12.04 is slow, unstable and has a
  weak signal.

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  In Windows 7 the signal is excellent, stable and strong. I use the
  netbook for every home, but in Ubuntu you can only connect a few
  meters away. In my university can not connect because the signal is
  too weak. In Windows 7 is okay. Everyone in my building at the
  university can connect very well with Windows. Who uses computer ath9k
  driver, no.

  Just search on Google to know that everyone who uses Atheros AR9285 have problems, even with computer hardware certified by Canonical:
