Windows 10: My computer stops working after I use the WiFi

Motherboard: ASUS STRIX 270E

Chip: Intel i7-770K

GPU: Asus STRIX 1080ti

RAM: 16 GB DDR4-3200

Operating system: Windows 10 64bit

Storage: SSD for windows and an HDD for everything else.

Hello. I have a computer that I have had for the past 4 years that has suddenly crapped out on me. I can connect to my wifi and it will say I have a stable connection. I'll even be able to pull up a few web pages. However, my computer starts acting up as soon as I try to download something or watch a video. Then, my computer disconnects from the wifi and says it can't find any networks. Then it won't let me open my settings or my network list. My computer basically grinds to a halt at that point and refuses to work. If I connect with an ethernet cord my computer works completely fine. I've tried a full reset of my computer and downloading a brand new copy of windows. I've also updated my wifi driver off of the Asus website. I don't know what to try next and I'm afraid it's a hardware issue. Does anyone have any ideas?

tl;dr: computer stops working when connected to wifi, but works fine on ethernet.

Wifi stops working when using ethernet

If the computer is unplugged from the ethernet, does the wifi work?

 

Lumia 930 WiFi stops working

Have same issue on a 930, the 920 doesnt have the issue at all so can confirm its model specific.

I can replicate the issue following the steps below. Anyone else have it following these steps?

• Restart the phone
• Connect to 2GHz wifi network (connects)
• Disconnect from wifi
• lock screen and leave it for 15 mins
• Connect to 2GHz wifi network (fails)

 

New computer setup wifi not working

I am trying to set up a new Lenovo IdeaCentre A540 Series all-in-one running Windows 10 Home. When it was walking through the initial setup, it detected several nearby WiFi networks. I had a problem getting the mouse connected and was not able to set the WiFi network. It was turned off and back on and then, upon getting back to that step, did not detect any WiFi. In Network and Internet settings it has no WiFi adapter listed and no WiFi options anywhere. I did make sure network discovery was turned on and I checked in Device Manager that the network adapter was enabled, but it doesn’t show up anywhere but in Device Manager.

Under Network Properties, it does list WiFi and says “Qualcomm Atheros QCA9377 Wireless Network Adapter”, status not present and connectivity disconnected. Under Device Manager I don’t see that adapter, it shows “Realtek PCle GbE Family Controller”, which appears to be the Ethernet adapter maybe? and a variety of WAN Miniports.

I’ve pretty much maxed out my knowledge here and I can’t find this exact issue when I search, so any advice would be much appreciated. Trying to help my stepdad set up to work from home during the pandemic...

Welp, now it's working. I realized I could show hidden devices in Device Manager, so I found the wireless adapter there. It was showing as not connected, so I shut down and dragged everything to another room and connected an ethernet cable, whereupon the wireless adapter started working perfectly. Maybe it was turning it off and back on the third time that worked, who knows...
