I am newbie in this area and I try to follow the instructions of @Ingo from here since days Link
I have Raspberry 4B 2GB with on board wifi and additional WIFI dongle "TP-Link TL-WN823N"
I started with installing the latest Raspberry PI OS (32-bit) from 11 Jan 2021.
I could sucessfully connect to my wifi and make an update
sudo apt update && sudo apt full-upgrade && sudo reboot
Then I sucessfully installed my dongle based on this manual Link
After that I followed the instructions from Ingo linked above incl. Enabling systemd-networkd and then
sudo -s
and following
Wlan0:

Result: All 4 files has been created sucessfully and the AP is running so that I can connect into it, but my Raspberry doesn't get any internet connection. I tried with different networks but I never got my Raspi connected with any network. I don't use any MAC filter or any restrictions on my Fritzbox. I also tried to connect to a secured and also an unsecured mobile phone hotspot and failed as well.
It shows following icon:
I also even can't connect to any wifi manually anymore, have first to delete all the created config files and then it is possible again. I tried several times to repeat all the steps but it just doesn't work.
One line which name is "suffices" says translated from German "Error during reading the interfaces. Devices couldn't be found."
Does someone know what is wrong? Please help.
Thanks in advance!
