Hello, and welcome aboard.

You forgot to tell us what external wifi adapter you have and you posted the topic into the wrong forum section.

Could you please be more detailed about your issue?

my problem is the following when I want to connect to different Wi-Fi networks with the external USB adapter, I can not connect, it connects and it is constantly disconnected my adapter is alfa awus036ach with chipset RTL8812au

i searched the chipset around the web and i found that its linux support is terrible at the moment, but fortunately there is a proprietary driver that can be manually installed by following the steps described in the following link

hello palinuro now I have detected that my parrot does not recognize any wifi network and does not recognize the wired network
in both networks says: the device is not managed.
Restart the network manager service but I also did not get results.
What could be happening?

sudo apt-get update
sudo apt-get install linux-headers-generic build-essential git
git clone https://github.com/abperiasamy/rtl8812AU_8821AU_linux.git
cd ~/rtl8812AU_8821AU_linux
make
sudo make install
sudo modprobe 8812au

Should work.

When Update Manager installs a later linux-image, recompile:

cd rtl8812AU_8821AU_linux/
make clean
make
sudo make install
sudo modprobe 8812au
