Title:
  ath9k wireless connection extremely slow

Status in linux package in Ubuntu:
  Won't Fix

Bug description:
  I'm not quite sure which package this bug belongs to, but it's a major
  problem I'm experiencing with Ubuntu Natty.

  I have a wireless-n wireless adapter on my computer, which uses the
  ath9k driver.  Network Manager says that I'm connected with a speed of
  130 MB/s.  However, my network connection is incredibly slow.  I did a
  test, transferring a large file over my wireless LAN, and the average
  speed was 25 kB/s.

  Let me repeat that.
  File transfer.  Wireless LAN.  25 KILOBYTES per second.

  However, if I compile and install the ath9k driver from compat-
  wireless-2.6, found at wireless.kernel.org, my speeds increase
  drastically.  With the compat-wireless ath9k driver, my wireless LAN
  file transfer test gets an average speed of 4.2 MB/s.

  Regular Ubuntu ath9k driver: 25 kB/s
  compat-wireless ath9k driver: 4.2 MB/s

  Something is very wrong with the ath9k driver that comes with Ubuntu.
