Your system is not up-to-date. There were problems in older kernels with ath9k WiFi driver. Please consider updating to newest packages.
Running 2.6.38 what kernel do you recommend?
I'm having a very similar issue with the same chipset, so I am writing it here.
I'm using the same netbook with F16, and my issue is the following:
A newly booted machine works fine, it can connect to the router with no problem.
But after a while, while using the PC, or in a suspended state, the wireless is down. Network manager tries to reinstantiate the connection, but no luck, everytime as if the password didn't match, it asks me what the password to the router is.
Here's an excerpt of my /var/log/messages file, while this is the case.

There's a huge number of this in the log.
Also, when the wireless is shut down from the menu, (that good looking on-off switch) it can't be made "on" again, the wireless hardware becomes "unavailable".
I can give you more information, but I should be guided a bit.
Anil, your problem is caused by ath9k driver issue and I think it's a duplicate of bug 736435.
I'm not sure if the daren's issue is the same.
This message is a notice that Fedora 15 is now at end of life. Fedora
has stopped maintaining and issuing updates for Fedora 15. It is
Fedora's policy to close all bug reports from releases that are no
longer maintained. At this time, all open bugs with a Fedora 'version'
of '15' have been closed as WONTFIX.
(Please note: Our normal process is to give advanced warning of this
occurring, but we forgot to do that. A thousand apologies.)
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, feel free to reopen
this bug and simply change the 'version' to a later Fedora version.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we were unable to fix it before Fedora 15 reached end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora, you are encouraged to click on
"Clone This Bug" (top right of this page) and open it against that
version of Fedora.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
