The contents of /bin/dmesg for one of these 1-minute downtimes
Description of problem:
Every so often (it seems like once every 10 minutes or so) my upload and download rates will drop to zero for about a minute. Checking /bin/dmesg, it's flooded with various messages, repeated several times (see attached)
Version-Release number of selected component (if applicable):
Kernel version 3.3.2-1.fc16.x86_64
Connect to a WiFi network and eventually experience a sudden lack of connection for about a minute.
No sudden loss of connection.
It looks like your link is going up and down rather quickly. Is it possible that you are near some source of intermittent interference (like a public microwave oven in a breakroom)?
please answer John's queries and provide us with as many debug data, lspci -vvvxxx

This is at home, and there are no non-wifi radio devices I am aware of besides a microwave which is definitely not in use when this happens. If this is radio interference, I have no idea what's causing it.

Results of lspci -vvvxxx attached. I will attempt to install the modified kernel at a later point.
Also, I have a Windows computer that doesn't seem to have this problem. Could it possibly be hardware-created interference? If that's a reasonable possibility, how would I tell?
