Hi,
in /boot/dietpi.txt the text says:
>> Networking Options -----------------------------
#If both Ethernet and Wifi are enabled, Wifi will take priority and Ethernet will be disabled.
I enabled both, switched in /etc/network/interface wlan-power to on and both LAN and WLAN works:

So I don’t understand the hint.
