Macbook Pro 2012 Catalina 10.15.6: Wifi will not turn on.
Macbook Pro 2012 13 inch non-retina, Catalina 10.15.6:
Today the wifi turned off and will not turn back on. Clicking "Turn Wifi On" on the Network page has no effect. The computer was on and in sleep mode, and displayed this problem after waking. I have tried to restart several times.
Sometimes the wifi symbol at the top of screen is blank inverted triangle, or sometimes it has faded lines. Based on the options shown when clicking the symbol, sometimes it thinks the wifi is on (only gives option to turn off, even when the wifi symbol is blank. When the wifi symbol shows faded lines, it will not display / identify any wifi signals.
On the network screen, it always shows that the wifi is off, and clicking to turn it on has no effect. Internet works fine through ethernet connection though. Other devices currently work fine with wifi.
