Dear all,
thanks to your advices I solved all my problems.
I had more of one service that tried to manage the wifi, it wasn't a bug
in the driver.
I solved with:
systemctl disable NetworkManager-wait-online.service
systemctl disable net-auto-wired.service
systemctl disable net-auto-wireless.service
Thanks for your advices and for your work on the Linux kernel.
Best regards.

Dear Developers,
my name is Paolo Zaffino and I'm an Italian GNU/Linux user.
I have an asus NV56 with an Intel Corporation Centrino Wireless-N 2230
(rev c4) wifi card.
I installed Arch Linux at 64 bit, my kernel version is the 3.8.7-1 and
I use Gnome with Network Manager.
I am facing a strange bug in the wifi driver.
I am able to get a working connection to many wifi networks (open and
wpa), but in other cases I can not connect to them or I connect but
every 30 seconds (more o less) the connection drops.
In this last case dmesg return this:

I'm here for further infomations about hardware or configurations.
Unfortunately this is a nasty problem for me and for a plenty of other
users that are in the same situation.
Thank you very much for your great work!
Regards.
