Hello,
I have an HP Elitebook 8460w laptop containing a Centrino Ultimate-N
6300 AGN (linux-3.8.6 iwlwifi module - firmware version 9.221.4.1
build 25532)
I am unable to remove the softblock on the chip with rfkill. For the
most part my wifi chip stays soft blocked. The only time I can manage
to get it unblocked is when the wlan0 interface is hard blocked.
I am able to:
- soft block the interface
- hard block the interface
- hard block and softblock the interface
I am not able to:
- soft unblock and hard unblock simultaneously.
I needed to do a fresh install of Gentoo Linux on a new hard drive. I
don't have access to the old hard drive at the moment, but wifi did
work on this older install of gentoo linux.. I am using the iwlwifi
driver and firmware that are part of Gentoo.
After I couldn't get wifi working I installed Windows 7 and the wifi
works fine when I boot into Windows 7.
I have looked many places for a solution and other people have run
accross this problem but none of their solutions work for me.
Here are some of the things that I have tried that have resolved this
problem for others, but not for me:
- unload and reload the iwlwifi module
- disable rfkill and bluetooth in the kernel
- boot with the hardware wifi switch off
- boot with the hardware wifi switch on
I have these kernels installed and ready to run on the new harddrive
they all exhibit this same behavior:
linux-3.6.11-r2
linux-3.7.10
linux-3.7.10-r1
linux-3.8.5
linux-3.8.6
I started out with linux-3.8.5 on this new harddrive. Wifi was working
fine with linux-3.7.10-r1 on the old harddrive (same machine). If
anyone has any insight into how I might solve this problem I would
really appreciate a push in the right direction.
Thanks

Below I've given a record of some of the commands I've tried to use to
unblock rfkill and some info about my system:
