Public bug reported:

I experience very frequent wireless network deconnections on my laptop.
A typical case is when I close the screen : when I open it again, the
network is systematically gone.  Sometimes it's just that the wifi
options won't show up in NetworkManager dropdown menu, but on other
occasions the menu says that the wifi has been turned off with a
hardware switch (there is no such switch on the laptop).

Syslog shows crashes related to iwlwifi (search for "Trace" in the
attached file).

Sorry for the poor report, but I don't have much time to narrow down the
issue.  Of course I can add whichever information is needed.
