2011 Mac Mini, base i5, upgrade to 8GB RAM, 512GB SSD, wireless keyboard, macOS 10.3.4 I have a recently developed quirk in my Mini. On occasion, it will lose the connection to WiFi and show nothing in the dropdown. Usually it has 4 or 5 devices broadcasting that it sees. If I reboot, it also sees nothing. I have to reset the PRAM before it works right. Any ideas as to why? The WiFi works fine once it is reset, but it has to be reset every time. Many thanks!
