It sounds to me like the wifi card has bad contact in the slot it goes into, since both the wifi and bluetooth are disappearing.
Either that, or the actual wifi card circuit board is going bad.
I suggest that you remove and firmly reseat the wifi card and see if that resolves the problem.
Leave the antennas connected if you can to facilitate an easy reinstallation of the card.
Here is the link to the service manual for your notebook. The wifi card R & R procedures can be found in chapter 6, starting on page 61.
Unfortunately, it is not very easy to get to where the wifi card is located.
What model wifi adapter does your notebook have?
I'll give you the link to the latest W8.1 wifi driver for it.

Read the chapter in the service manual I posted above for how to remove the wifi card.
The parts list states that your notebook has a Ralink RT3290LE 802.11bgn 1x1 Wi-Fi and Bluetooth 4.0 combination WLAN adapter.
These would be the latest drivers for that card.
But if it is not showing up in the device manager, the drivers probably won't install.

That is why I think there is an electrical contact issue with the wifi card--or there is a hardware issue with the card itself.
It should be on all the time and not randomly disappear.
You shouldn't have to be resetting the PC and whatnot.
Anyway, I have given you the only suggestion I can offer.

The wifi and bluetooth is one card.
Once you have the notebook open, if reseating the wifi card does not work, let me know how many antennas are connected to the wifi card in there now, and I will give you the link to a better replacement card.
Usually you can open the notebook with a set of jeweler's screw drivers. You may also need an old plastic credit card to help pry the plastic open, so that you don't scratch or mar it.
The manual should tell you exactly what you need to do.

If you don't live in the USA, I wouldn't be able to help you.
You should be able to pick up a set of jeweler's screwdrivers at any local hardware store.
You need a set that looks like this...
