Windows 10: Wifi Adapter Not Recognized by Windows 10 at All.

My usb wifi adapter isn’t being recognized by Windows 10 at all. It doesn’t show up in device manager, and when I troubleshoot the internet connection it tells me to plug in an ethernet cable - as if there is none connected. It is a Realtek 8812BU. I have tried everything the internet has told me. I updated the drivers, unplugged it and plugged back in, executed multiple commands, and even bought a NEW WIFI ADAPTER!! It happened with the first one, so I bought a new one which worked for a week - and then the same problems persisted. Sometimes I’m lucky and it will work for 2 seconds, but goes right back to not showing up. Obviously this means I can’t connect to the internet. I am on a desktop. Somebody please help, I need this computer to do work.

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

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.
