Zoltan: can you collect some more data for me? Please download
http://people.canonical.com/~sforshee/wifi-debug, then open a terminal
and make it file executable ("chmod u+x wifi-debug" in the directory
where you downloaded the file). Run "sudo apt-get install iw trace-cmd
tcpdump" to install some needed tools, then run "./wifi-debug -t -p".
This will start collecting data. Leave it running until you experience
wireless problems, then press Enter to stop collecting data (this
collects a lot of data, so if this problem takes a long time to happen
you may want to periodically stop and restart wifi-debug as long as the
connection is stable as well).

Once the script finishes you should have a file named wifi-debug-
files.tar.gz. Please give me this file either via email or by uploading
it to some kind of online storage and providing me a link. I don't
suggest attaching it to this bug report.

Please note that this script will log your network activity and the
activity of other wireless clients on the same channel (though traffic
from other clients will be encrypted if connected to a protected
network), so anything you do on the wireless connection while it's
running will be captured. I won't be looking at the actual data sent
over the network, and anything sent over a secure SSL connection will
still be encrypted, but you may want to restrict your activity while the
script is running to avoid having any personal or confidential
information captured. If you aren't comfortable with having network
activity logged you can omit the -p option to wifi-debug. In that case
only mildly private information such as network addresses will be
collected, but that will also limit what I'm able to do to help you.

Thanks!
