Loosing WiFi after running apt upgrade and rebooting

[Petrakis]

Solution: Wifi not connecting after apt upgrade

apt upgraded Wi-Fi & disappeared after reboot. To fix this in terminal do sudo raspi-config, you can get it restored by > Advanced Options > Network Config > selecting [dhcpcd] instead of [Network Manager] and rebooting the OS.( if you don’t see that option in raspiconfig update the tool by hitting update it will then show.)
