Wifi not connecting without Ethernet cable


Basically what happened before: After updating to Windows 10, my computer was not showing any network options. (The icon says "Not connected - No connections are available) Going into Control Panel/Network and Internet/Network Connections, it then says "Local Area Connection Network cable unplugged". I ran diagnostics and it said to plug in the ethernet cable to the network adaptor. So my wifi connection will not work with my laptop unless directly connected to by the ethernet cable. Wifi works fine with phones, ipods/ipads, and another laptop that was also updated to windows 10/a desktop still using windows 8.

 

Windows 10 No Longer Connects to Ethernet and WiFi

This week brought Win10 ver 1903 and I can no longer get WiFi to connect if the ethernet cable is plugged in. If I boot with ethernet, manually trying to connect WiFi silently fails. If I boot without ethernet, WiFi is automatically connected yet drops
if I plug in the ethernet cable. Both the WiFi and the ethernet work fine by themselves, just not at the same time so I don't think it is a driver problem.

Any suggestions would be appreciated

 

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!
