Windows 10: Wifi adapter

My physical wifi adapter has been damaged for unknown reasons. I then purchased a WiFi usb dongle. It worked for a while. Currently when I insert the WiFi dongle my computer shuts down and resets. I've tested the dongle on other devices and it works fine. I've done a recovery to previous dates, I've updated all drivers etc. I've done everything available on the Internet. Now I notice when I run my pc in safe mode, the dongle and Internet works. It only shuts my pc off when I try to use it as normal. Where can I start looking?

I keep losing my WiFi adapter

I tried the Option 2 approach but kept getting the Error NetSetupDeleteObjecton Network Adapter error (0x80070005) error, even after a dozen executions of the command. That seemed like it was going nowhere so I tried Option 1.

After completing the reboot in Option 1, I never got the dialog that asked if I wanted to make the computer discoverable, even after a significant wait.

Do you have any further suggestions? I'm going to move on to "Compumind's" suggestion in the meantime and see if that helps....

I started working my way down the list.

1. Both the ipv4 and ipv6 resets said "access denied!". However, the mere attempt worked *briefly*, then the WiFi went down again.
2. I disabled and re-enabled the network adapter. Again, it worked *briefly*, then I lost the WiFi again.
3. I tried to disable the antivirus but couldn't find a setting for that so uninstalled it entirely. I got the WiFi back and this time it stayed on for several hours instead of a few minutes so I assumed it was fixed. Then I installed the new Avast One and the WiFi is still working so I'm assuming that all is well finally!

Thank you for this list of suggestions!!!

 

Wifi Adapter

Here are several methods:

• Look in the user guide - see if 5 GHz WiFi is mentioned.
• Find that model on the manufacturer's website - see if the manufacturer advertises 5 GHz capability.
• Look for independent reviews of your model - the reviewer will certainly mention if the adapter supports 5 GHz

If none of those provide the answer, I can suggest many more ways to find out.

 

Wifi adapter disappears - goes 'hidden'


Running Windows 10 on an Acer laptop. Over the past month, the wifi connection dropped without explanation/warning.

First time, the adapter was visible in Device Manager (with a yellow triangle next to it). An interent search found the suggestion to uninstall it and restart. That worked.

Today, the connection dropped again. In Device Manager at first I could not see the wifi adapter listed. I clicked to see hidden devices and found the adapter and the Bluetooth (which I had not noticed was missing).

I again uninstalled, restarted, and both the wifi and bluetooth have returned.

Anyone any ideas as to what is happening, why it's happening, and what I need to do, please?

I have attached a screenshot of the DM windows as it is now, showing the wifi adapter name, etc.

Thanks very much
