Windows 10: My Laptop will no longer connect to my working Wifi network.

I use an HP Elitebook 840 GS laptop, which runs on windows 11 at the current latest version. Seemingly out of nowhere yesterday, my computer stopped connecting to Wifi on any network entirely. Wifi no longer shows up as an option at all on my device in settings, and the only available option seems to be ethernet, which the system thinks I'm trying to connect to in any troubleshooting effort. I know for a fact my wifi network works, because I'm utilizing it on my desktop to send this request out. I attempted to restart the computer, update the computer to the most recent date, reset the network

Wireless connection no longer working

The wireless connection to my laptop is no longer working. I went to "network settings" followed by "wireless network connection" and the switch is turned to "off" and cannot be changed to "on". I went to "manage wifi and everything is turned on or checked. Under "known networks" mine is not listed. I rebooted the router, the wifi and the computer but nothing changed. Wireless is running normally to the rest of my computers.

Does the wifi hardware in your PC show any errors in device manager?

 

How to connect to an existing wifi network?

As you suggested, I tried disabling the ethernet adapter and that caused wi-fi to connect, so the desktop wifi does work. Also, I accessed the router and changed the wireless network name (to wfCHS). Thanks!

However many problems are still unresolved:

My laptop behaves just as I want it to. Assuming the router has wifi turned on and the laptop has an ethernet connection, connection to the internet is by ethernet (no private network name), and the wi-fi connection is to my private network "wfCHS", but with no connection to the internet. (If I disconnect the ethernet cable, then wfCHS becomes connected to the internet and stays that way even if I reconnect the cable.) A directory listing shows both laptop and desktop under "Network". Great!

Things are rather different with the desktop. With Ethernet disabled, the desktop shows a wi-fi connection to the internet. Under Settings > Status it's called "wfCHS" but under Network Connections it's called wfCHS2. If I then re-enable the ethernet connection, the wifi connection stays enabled for a minute or two, then disconnects. Further, the ethernet connection is given the name wfCHS2 under both Status and Network Connections.

Why does the desktop give an (unwanted) name to the ethernet connection while the laptop doesn't?

Why does the desktop disconnect its wi-fi connection a minute or so after the ethernet connection is enabled, while the laptop doesn't?

Why does the desktop give two different names to the wifi connection, depending on whether it's viewed under Status or Network Connections, while the laptop doesn't?

Why does the laptop show the desktop under Network, while the desktop shows only itself?

Things are so convoluted that I'd be happy to start over. I've had the desktop "forget" the wi-fi connection as you suggested, then re-established it, but this hasn't helped. Can the ethernet connection also be "forgotten"?

Really appreciate the help you've given so far!
