After booting the first time kali-linux-2019.2a-rpi3-nexmon on the Raspberry Pi 4 (4GB) everything works fine - wifi is working.

But after executing
Code:
sudo apt-get update && sudo apt-get upgrade
and rebooting the Raspberry, the wifi is not working anymore. It seems that the wlan interface is missing, because the command
Code:
iwconfig
returns no wlan0 interface.

Adding a wlan0 interface to the /etc/network/interfaces file and restarting the network-manager via
Code:
service network-manager restart
doesn't solve the issue.

Is this issue known?
Do you know what I can do to bring the wifi back?
