Wifi Connect to a WPA2 Enterprise Network

  1. You need to connect to internet at first by any way

  2. Install the needed packages with the following command:

    1
    sudo apt install network-manager network-manager-gnome openvpn openvpn-systemd-resolved network-manager-openvpn network-manager-openvpn-gnome

  3. Remove unneded packages:

    1
    sudo apt purge openresolv dhcpcd5

  4. Replace /etc/resolv.conf with a symlink to /lib/systemd/resolv.conf. Do not execute this command on Raspbian 10, it will break your DNS:

    1
    sudo ln -sf /lib/systemd/resolv.conf /etc/resolv.conf

  5. Now go to the top of your screen and reconfigure the panel: open “Panel Settings“ -> “Panel Applets“: remove “Wireless & Wired Network“. The network manager applet should appear after a reboot.
