I have a MacBook Pro (Retina, 15-inch, Mid-2015), 2.5 gHz, Quad-Core Intel Core i7, 16 GB 1600 MHz DDR3.
Upgraded to Bug Sur 11.0.1 this morning.
When I upgraded my MacBook Pro, it was connected via Ethernet.
When I disconnect the Ethernet and tried to connect via WiFi (5G), the MacBook says it is connected via Wi-Fi but I am not connected.
I have to shut down the MacBook Pro and restart. Then I am able to connect.
So, Bug Sur was not a typo. I deliberately typed Bug........
Is there a fix?
