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: [ 25.459573] iwlwifi 0000:03:00.0: RF_KILL bit toggled to enable radio.
