When I upgraded from 10.14.3 to 10.14.4 I lost my wifi. It says "WiFi No Hardware Installed." I just did the standard software update via System Preferences. I have an approved PCIe card from the Buyer's Guide and it's worked perfectly for a couple of years until this week. I saw a posting about shutting down and unplugging the computer. I didn't give it much credence but tried it anyway. No luck.
Any advice would be most appreciated.
