Problem with Wifi after sleep

syslog of wireless trying to reconnect
Description of problem:
Wireless connections work fine, until it wakes from sleep. I
see three "direct probes" (among other things), and then connection fails.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Go to sleep (suspend)
2. Wake up
Wifi cannot reconnect. Even disabling (hardware switch) and re-enabling does not bring it back. I have to shutdown (or hibernate), and then it works.
Also discovered that when it wakes up from sleep, it couldn't even see the
access point it was using before (according to Network Manager...or maybe it
had just removed it from the list since it couldn't connect). Disabling the
wireless by both software and hardware switches solved the visibility problem,
but did not resolve the connection issue.

"fail to flush all tx fifo queues" problem after resume from suspend.
Does the problem happen on updated kernel 3.10 ?
If it does, I'll request you for some more debugging information.
How might I go about installing said kernel? I have fedora-updates and fedora-updates-testing enabled and I do not have the option to install a 3.10 kernel.
Oh, seems repositories are not updated. You can download kernel from here:
and install by "rpm -ivh kernel*.rpm"
I downloaded the kernel and installed
After a sleep, the wifi comes up just fine! Woohoo! Thank you!
I put this through several cycles, and it came back every time. I think we can mark this one as resolved, pending new kernel.
I just realized: I am still running 3.9.10-200, which is working for some reason. It appears the kernel-3.10.4-100.fc18 package didn't set itself as the default to boot when it was installed.
I went through several cycles with the 3.10.4-100 kernel and it worked fine. Just so you know. :)
