Hey , I am currently experiencing a major problem in my system . It seems that the wifi software has been deleted i.e. the wireless adapter driver and the software has been somehow been uninstalled . This issue began after the recent Windows 8.1 update .
These are my laptop specs :-
Operating System: Windows 8.1 Single Language 64-bit
System Model: HP ENVY 15-k004ne
Processor: Intel(R) Core(TM) i7-4510U CPU @ 2.00GHz (4 CPUs)
I've tried to fix the issue by installing all possibly compatible drivers and softwares but none of them seemed to work .
I've also reset my pc to factory state using windows recovery as well as Hp recovery and yet the problem was not fixed .
I also checked online for solutions but since the laptop products vary , the issue does not seem to be fixed .
Looking forward to helpful advices ... :)

If a Factory Fresh install has not worked, then there is the possibility it is disabled in the BIOS or the Hardware has failed.
If it is software related...
Then we look in Device Manager; View; Show hidden Devices to see if it is actually acknowledged.
NEXT... As an adminstrator, in a Command Prompt Window, type
This will list MAC addresses for those items that are present, and may not be connected.
A good number would be 3,
1 x Ethernet
1 x Wi-Fi
1 x Bluetooth
and then type
and in the long list look for named devices have a matching MAC address.
Along with Device manager this is a way to determine the number of devices.
netsh wlan show drivers
netsh wlan show interfaces
ping 192.168.0.1 (your default gateway)
Now you should have an idea if the Physical Hardware exists, and if does are there any drivers or addesses etc associated with it. If you then post any relevant details we can move on to the next step.
If in doubt please ask.

I just checked the BIOS after seeing your post . No sign of any network adapter being disabled
I also typed those commands in command prompt as admin , I received an address (or whatever it is called)
for the ethernet . My bluetooth is not turned on so I did not get the addresses for bluetooth . Even though I have a wifi connection I received no address for Wifi connection . Instead , in the end I got a message saying "There is no wireless interface on this system " .
Looking forward for more suggestions ... :)
Thank you .

So what have we learned, very little.
We still know you do not have a Wi-Fi card enabled, except that you do "Even though I have a wifi connection I received no address for Wifi connection . "
So yet again I will ask, not so obliquely, to POST THE INFO. Device Manager screenshot, and address listings.
Physical Address Transport Name
B0-5A-DA-DE-84-28 Media disconnected
48-E2-44-54-66-28 Media disconnected

I actually ment there is a wifi set up at my place which works perfectly . Somehow it is not detected by my laptop .
As you can see there is only 1 address that is displayed . It is the ethernet address (since I'm using cable to access the internet) .
This is the device manager screenshot :
There is a driver only for Ethernet and not for wifi .

The best solution is Hydrochloric acid...
But the answer from what you have given is the adapter has failed, but a software update should not have caused that.
