Wi-Fi disconnects from internet after resuming from Sleep Mode

Howdy folks,
Google gives me the impression this is not an uncommon issue.
* I've tried the suggestion of deselecting the "Allow the computer to turn off this device to save power" option. That's not working for me.
I'm looking for a way to troubleshoot and fix this issue.
* Windows 10 Pro Ver. 1903 Build 1862.388
* Performing a Restart usually gives a temporary fix.
* If the internet doesn't disconnect, I'm usually seeing a very slow speed; e.g. 20 Mbps vs. normal at 130-180 Mbps.
* Wi-Fi Adapter: Intel® Dual Band Wireless-AC 3168
* Desktop: PowerSpec G355 (Installed ~3 months ago.)
* This recent problem was first addressed with Comcast replacing the modem/router: Ethernet cable speed increased close to 500 Mbps.

Thanks in advance to all who read this and to those who reply!

Issue Resolved by uninstalling and reinstalling the Network Adapter.
See attached.

Additional option:
Command Line Winsock Reset
WIN + R
"netsh winsock reset" (without quotes)
Enter
Restart
Reconnect internet settings (Router name & password)

That seems to involve a restart.

There are quicker ways.

All that is needed is to disable the network adapter (ethernet or WiFi), and then re-enable it!
Lets do it manually:
+R (Run shortcut) and type ncpa.cpl and press <enter> to bring up the Network Connections control panel:



Select either the WiFi adapter (this is commonly the adapter that gets confused), or Ethernet if that is problematic. From the toolbar that appears, select Disable this network device and the device is disabled:



Now select Enable this network device and the device is enabled and it should automatically connect within a few seconds. Sometimes it is necessary to select Connect to and select the WiFi network you want:



No restart required. See here for an even simpler way with a batch file:
