Macbook Pro: mid 2017
MacOS: Mojave 10.14.6
Problem: After the Mackbook Pro sleeps for a while (tens of minutes), when I open and wake it up, the Wi-Fi connection is blocked (i.e., internet not accessible, browser webpage loading failed) but the Wi-Fi icon the top menu bar looks normal.
Then I will have to turn Wi-Fi off and on and the internet connection will get back to normal.
Any advice on how to avoid the Wi-Fi connection blocking after wakeup? Thanks.
