khanmoin19,

1. Open Settings from the Start Menu and select Network & Internet.
2. Click Wi-Fi on the left pane and select Change adapter options.
3. Right-click on your Wireless Network Adapter and select Properties.
4. Under Networking tab, select Configure.
5. Click on Power Management tab and check the Allow the computer to turn off this device to save power box, then click OK.

For my notes, click my username and send me the pc service tag number via private message.

doesn't work because this OPTION DOES NOT EXIST

In my case, same issues with adapter "Killer AX 1650";

The fix is going to Power options > Advanced settings > Networking connectivity in standby: Choose "Enable", instead of " Managed by Windows", for both "On battery" and "Plugged in". This would probably drain the your device's battery during sleep, however, it would fix the issue.

In case, "Networking connectivity in standby" is not showing up in Power Options. Follow below steps:

1. Go to Registry Editor "Regedit"
2. Follow this path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\F15576E8-98B7-4186-B944-EAFA664402D9
3. Set Attributes DWORD = 2
4. Restart the device

Hope this helps
