I have used the following image and installed the OS in the emmc.
Initially, I have the desktop and I can setup the wifi connection as normal. Once I run the commands
sudo apt update
sudo apt upgrate
and when I restart the board there is not wifi device at all. The sudo ifconfig -a command does not show any wifi device at all anymore.
I have tried this already four to five times and I am pretty sure that something happens when I upgrade. Furthermore, after upgrade there is no hdmi output aswell I have to use the COM port.
