edit: right now, I decited to play with the device which encountered this issue and found following:
After restart, device has no wireless interfaces. However, exactly at the moment i delete interface graphing, wireless interfaces appear.
I repeated this step on purpose several times and it worked every time. For now, if you find yourself without wifi, delete (at least temporary) your graphing interface and it should appear.
Thank you vecernik87 for the input!
But I have no graphing interfaces. Device is stock, bought yesterday in local store, no configuration done yet. After first boot I thought that not working wireless will be fixed with fresh software. So I tried update packages and firmware to last stable and RC but no luck. Also I tried reinstall via netboot with the same results. No wireless interfaces.
Wireless LEDs (2GHz and 5GHz) blinking 2 times when booting then goes off and never came back.

I don't know if wireless device should appear as PCI device, but this list also empty anyway:

Same picture was right after first boot before any updates.
