Thanks Abdul,

I tried your suggestions.  The Network Adapter troubleshooter couldn't identify any problem and I have the most up-to-date Network Adapter driver.   I cleared the Allow the computer to turn off this device to save power check box, and then clicked OK.

When I brought the laptop out of sleep a few times it was ok but most recently it was disconnected from Wi-Fi so I had to click Wi-Fi and select the connection to my Wi-Fi which was never necessary prior to Windows 10.
