Vanished wifi!

I’m a week into working with Win11 on my new machine. The fresh install went well.
I had internet, used the 5gig channel. We have a fiber connection so it’s fast and dependable. The wireless router is pretty good for an ATT product.
Yesterday the WiFi disappeared from the computer. I opened the little icon in the tray and there are no networks listed. There were at least 8, including the two in my house. Gone. Not a single one!
I checked the antenna, was good. Rebooted numerous times. No luck!
Even ran the troubleshooter. It was insistent on having an ethernet cable attached.
I never had any problems with the WiFi before. All the other computers are online.
I’m really stuck on this one! I’m a WIN10 User dating to day 1, so have a clue.

I'd start by looking to ensure your PCs wifi is even working/On. Next check the Device Manager to see if the Wifi adapter is working. You can also check the internet icon in the lower right of the system tray to help ensure the wifi radio is indeed ON.

First off try updating your Win 11 to the latest build 23H2 22631.3880 then report back

Sorry for disappearing, things became complicated.
Great news is when I got back home and restarted the computer, it logged into my wifi. While away from the PC causing all the angst, I discovered a huge amount of information about this issue. I am startled that so much difficulty exists with a basic function!
