Well, I still don't know why, but my second WLAN AP (no DHCP server) was causing this. After rebooting the device the DHCP worked like expected.

Thanks to all who helped.

Has your tp-link WiFi dongle ever been used successfully on this or any other RPi? Yes, it has worked on this RPi with the same OS a few times in the beginning.

Take a look in /etc/wpa_supplicant/wpa_supplicant.conf. Does it show a country code also? Yes, it does. This is the complete file: pi@raspberrypi:~ $ cat /etc/wpa_supplicant/wpa_supplicant.conf ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev update_config=1 country=DE network={ ssid="yyyyy"...

Did you set up everything correctly in raspi-config? Your wifi won't work unless you set the country code.

I did. And I guess the "alpha2=DE" shows wpa_cli knows it.
