Hi Gunnar

I must say, I have not been able to find WiFi (not even a "firmware
> required" message). Could you help me find it, so it makes its way into
> raspi3-image-spec <https://github.com/debian/raspi3-image-spec>? Thanks -

I have also struggled with WiFi. Could the "missing WiFi" issue be related
to https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=911443?
The WiFi (wlan0) reappears if I combine the 4.18 kernel with the device
tree binary of the 4.17 kernel.
The device tree change causing the absence of wlan0 might be this one:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/arch/arm/boot/dts/bcm2837-rpi-3-b.dts?h=v4.20-rc4&id=b1b8f45b3130dbd8704e5ea0d82b49b1d929498e

@Stefan and @Eric: As you are the experts here: Can you give us a clue why
the wlan0 interface disappears if we take the latest device tree binary
from 4.18 vanilla kernel?

Best regards
Matthias
