mac mini intermittant internet connection
Mac mini 2012 MacOS Mojave
suddenly 5 days ago the Safari would just freeze, either very slow (less than 10 Mbps download) or no connection at all. (No hardware changes) Mac mini connected to modem by Ethernet and WiFi. iPhones and iPads work just fine over the same WiFi, speed about 90 at the same time the Mac mini doesn’t function. This will last for a few hours, I don’t know exactly how long and then functions normally for a few hours. Turning off and on doesn’t help, quitting Safari and restarting doesn’t help.
Please help, also I’m a bit of a computer bonehead so any instructions offered should take this into account.
