Comment 1 John W. Linville 2013-07-20 12:25:25 EDT
We probably need to see the output from running 'dmesg' shortly after a reboot.

OK, there is output of this command. It is from actual liveCD with gnome, directly after boot of OS.
Comment 3 Stanislaw Gruszka 2013-07-22 05:40:10 EDT
There is no messages about iwlwifi, that module is not loaded. Either it is blacklisted or udev does not load it automatically. What happen if you do "modprobe iwlwifi" .

dmesg after modprobe iwlwifi

so I did it. modprobe iwlwifi has no output, but wifi still don't work. In attachement is added new dmesg output after this command, just for sure. 

I just did some google research for this problem and I find out, that on Ubuntu was something, what seems very similar. There is some patch, but it is in .deb and I am not sure if it can be used on rpm based system, in some way.
Comment 5 Karel Rozhon 2013-07-22 09:05:58 EDT
I also tried (after modprobe command) grep some info from logs.
pwd = /var/log

grep -ir iwl - no output

[root@localhost log]# grep -ir wifi

I looked into BIOS and it seems, that everything connected with wifi shoud be enabled. I also tried use fn + other keys, but with no effect.

Just realized that this patch is missed on 3.9 and it most like fix this issue

It is already on 3.10. Josh please apply it on 3.9 kernels as fix for this bug.
Comment 7 Josh Boyer 2013-07-22 14:51:54 EDT
F19 is rebased to 3.10 now, just not built yet.

I've applied the patch to F18.
