Wireless Network Adapter | Card just gone

[Cammons]

I was able to use my all in one (wirelessly) last on Friday 01/27/2017.

I didn't get on Saturday, but upon today (Sunday) have found that my pc does not connect to the internet wirelessly any more. I only have an option to connect via LAN. No wireless adpaters exsist on my pc. The last Windows update was on 01/13. 
ESET ( an antivirus software updated) updated on Friday, but I was still able to use my pc wirelessly. 

I downloaded and attempted to install the original wireless driver for the computer and got an error code stating I didn't have the minumum requirements with a 9996 at the end. 

The device manager shows nothing for a wireless adapater nor any unknown devices.

Thank you for posting on HP Forums,

As I Understand the wireless connection isn't working and the driver isn't listed in the device manager either,

Don't worry, I recommend you follow the steps mentioned in this HP troubleshooter: Click here

If the issue persists, please run a hardware test (Click here) on the wireless card and get back to me with the results.

Keep me posted,

@Riddle_Decipher,
Thank you for your reply. 
Before I posted to the forum, I had followed the HP troubleshooter you mentioned first in your response. I however followed it again for good measure just to make sure I didn't miss anything and still ended up with the sad results of nothing accomplished.

I tried doing the hardware test and it doesn't pull up on my Omni for some reason. The F2 button only pulls up a screen that ask if I want to boot my Windows 7.

I downloaded the most recent version of the UEFI, but still it does not pull up when F2 is pushed during pc boot up.

Thank you for replying and I can see why my words could seem confusing now that you've mentioned the "windows troubleshooter",

The link I shared isn't the same, on the contrary, my link asks you to select from a list of Operating Systems and other steps done to identify the issue and to resolve it.

Click here This is an interactive troubleshooter.

Also, if the UEFI isn't working for you, no worries, Just download and install the latest version of HP Support Assistant and run a test using it instead.

Keep me posted,
