Wireless network dies

[Steven Stern]

Since installing the latest kernel,  3.2.2-1.fc16.i686.PAE, my wireless
connection dies after several hours.  The access point is functioning
normally -- all other devices continue to work.

Once this happens, NetworkManager shows that wireless is enabled, but
shows no available networks. Stopping and restarting the service doesn't
help. It's necessary to reboot to restore the network connection.

Here's /var/log/messages at the time it went away.

and it repeats like this until I reboot.
