Description of problem:

Network throughput is unstable on my eeepc 1001px using the ath9k moudule for the AR2427 wireless device.
After compiling and installing the ath9k module from compat-wireless-2010-07-08.tar.bz2 all seems to works fine.

Version-Release number of selected component (if applicable):

kernel-2.6.33.6-147.fc13.x86_64

How reproducible:

While browsing random requests never end or are really slow to respond
During a ping, +10% packets are lost.
When downloading throughput is varying a lot during the download.

Steps to Reproduce:
1. ping with default ath9k, and see packet loss.
2. update ath9k from compat-wireless-2010-07-08.tar.bz2.
3. ping with new ath9k loaded, and see no packet loss.
  
Actual results:

packet loss

Expected results:

no or accidental packet loss
 
Additional info:

First tried kernel-2.6.34.1-29.fc13.x86_64.rpm from http://kojipkgs.fedoraproject.org to check if 2.6.34 fixed it, same results.

Then tried wireless-2010-07-31.tar.bz2, but it did not compile, with the following error

net/wireless/core.c:937: error: storage size of ‘vaf’ isn’t known

here a report
http://forum.ubuntu-nl.org/internet-en-draadloos/asus-eeepc-1001-px/msg632534/
suggesting compat-wireless-2010-07-28.tar.bz2 has the same compile issue.

Just gambled and tried compat-wireless-2010-07-08.tar.bz2 which compiled and all seems to works fine.
