Windows 10: When I launched a game on my desktop via ethernet connection, wifi disconnects

Hello,I tried many suggestions on the Internet. I am using ethernet cable for internet connection on my desktop pc. Everything is fine while surfing on the internet, watching videos or etc, wifi works fine too. But whenever I launch a game like Tricky Towers, PUBG, Cs Go, I still have internet connection on my desktop pc, I can play in online but on the other devices like my smart phone there is no wifi connection. When I close game, wifi connection is fine in my smart phone. I called my internet provider and they said there is no problem with the router or wifi. How can I fix it?Thank you fr

:)

 

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!

 

Make Windows 10 connect/disconnect to WiFi based on Ethernet connection status

Steps:

1. Go to Control Panel\ All Control Panel Items\ Network and Sharing Center > click on 'Change adapter settings' then use the 'alt button' to show menus and select Advanced Settings...
   
2. Under Connections section, select Ethernet, and use the arrows to the right to move Ethernet above WiFi.
   
3. Click OK.
   

Windows will now prefer the Ethernet over the WiFi for connecting to the internet. This should apply for Windows 8, 8.1, and 10.

 

Disconnected from Ethernet, WiFi still connected

Hello,
For the past 6 months I have had terrible internet issues, there was a problem within my area according to Virgin Media which was resolved 2 months ago. However occasionally I still get disconnected, but my Wifi stays on.

My PC is connected to the router via 2 powerline adapters. All devices which are connected to router wirelessly are fine and have a consistent high-quality connection. Whereas my PC has an inconsistent and sometimes low-quality connection. My speeds however remain optimal, around 46 Mbps download / 2.92 Mbps upload. The quality however is sub-par:






Sometimes I have around 2 - 10% packet loss.
Any ideas on why the PC connection isn't perfect whereas the Wifi connections are?
