This is my first time posting here.  Please let me know if I'm using the incorrect format, or if you need any additional information from me and I'll be happy to provide it.


I have a Windows 10 machine that for the past several months has had an issue where the USB Wifi device will intermittently stop functioning.  My PC will play the 'Device Disconnect' sound and stop recognizing that I have a USB Wifi device.  However, my USB mouse and keyboard continue to function normally.  I have tried changing which USB ports my wifi card is connected to and this does not fix the issue.  Once I restart my PC my wifi functions normally again - for a while.  Within a few hours the issue will happen again and I'll have to restart to remedy the issue.

If anybody could please help me identify the root cause of this issue I would really appreciate it.

I don't know if it's helpful, but I have attached my DxDiag

Thank you,

I would try the following.


Firstly, disable fast startup even though it probably is not related to your issue. It can cause other issues.


Second. Disable Selective Suspend.


Right click the USB adapter in Device Manager. Select Properties and under the Power Management tab make sure the box next to Allow the computer to turn off this device to save power is unchecked.


Set your Power Configuration to Maximum Performance. 


Sometimes Windows 10 gets confused if both USB Wifi and LAN is enabled. In Device Manager right click on your LAN adapter and select disable, not uninstall, to disable the LAN adapter. 


After doing the above reboot and see how the USB adapter performs.

Thanks for the prompt reply JohnC_21.  I've made the changes that you suggested and I've so far not seen any issues.  I will reply here if the issue occurs again :)
