Nice!
This is first time I get so many replays in so quick time
Thank you all.
So about your demands:
iwconfig shows:
lo no wireless extensions.
peth0 no wireless extensions.
sit0 no wireless extensions.
virbr0 no wireless extensions.
vif0.0 no wireless extensions.
eth0 no wireless extensions.
vif0.1 no wireless extensions.
veth1 no wireless extensions.
vif0.2 no wireless extensions.
veth2 no wireless extensions.
vif0.3 no wireless extensions.
veth3 no wireless extensions.
xenbr0 no wireless extensions.
Like I understand there is not only no wireless extensions for each of them, but there is no wireless interface at all, most of them like I understand belong to Xen (right?)
Output of ifconfig -a don't show more interfaces that you see above.
I downloaded rfkill, but it is not work (like you thought), more of that I don't have /dev/rfkill.
Here is provider's page related to my laptop:

(there are two versions (U and N, I don't know how to determine which of them is laptop that I use)
In user manual there is nothing that connects between wireless and OS, but from my experience, in past, when I try to run wireless, I remember that pushing side buttons get any result.
I actually found in BIOS option to disable wireless LAN, and now it make me much more calm.
So generally, now I more sure that wireless is inactive, but if you have something additionally to say I will more than glad to hear.
