[solved] WLAN connects, disconnects, connects ... (Realtek 8821ce)

To cut it short, device, system and all other things are irrelevant except the WLAN-adapter and it's firmware.

WLAN-adapter: Realtek 8821ce
Firmware: rtw_8821ce

It took me several days to find out, that the kernel firmware in all newer versions since 5.something is faulty.

Replacement with rtl8821ce firmware from Github solved the problem. Blacklist the rtw_8821ce.

Add to /etc/modprobe.d/blacklist.conf

blacklist rtw88_8821ce

Then

su -
apt install module-assistant build-essential dkms bc git linux-headers-$(uname -r)
git clone https://github.com/tomaspinho/rtl8821ce
cd rtl8821ce
chmod +x dkms-install.sh
chmod +x dkms-remove.sh
./dkms-install.sh
reboot
