MacBook connection to WiFi
After downloading new security software my MacBook cannot access WiFi. I’ve tried all the recommendations made by apple. The message on my network box is: WiFi has the self-assigned IP address ——- and will not be able to connect to the internet. It’s the same router and network that I’ve had fir years and my apple phone and desktop have no problem. Just my laptop.
MacBook Air 11″, macOS 10.15
