Title:
  Atheros AR9285 wireless working badly on Ubuntu 13.10

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  at the request of penalvch I've used ubuntu-bug linux to repost the
  bug originally reported in
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/947697/

  Please refer to the other bug report for other people suffering from
  the same problem.

  The problem: 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.

  Moving closer to the wifi receiver improves quality and sitting next
  to the wifi receiver I have an excellent and uninterrupted connection,
  so generally speaking, the driver works, but the problem is simply a
  much more limited range than I have in windows 7 (again, this is a
  dual boot system).

  This problem has existed ever since I bought the laptop (A lenovo
  b570e, running kubuntu 12.04 at that time, now kubuntu 13.10). The
  behavior is consistent across all wifi networks. I've conducted quite
  a bit of web searching, tried to install alternative drivers, etc but
  to no avail.

  If I can run any additional tests or anything else that will help you
  fix this issue, just let me know . My daily frustration using ethernet
  cables or my daily hunts for buildings's wifi receivers results in
  considerable motivation to help fix this :)
