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.
@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.
