After installing NetworkManager, you should be able to use NetworkManager (different icon) to connect to networks instead. If the installation is successful, the default "Wireless & Wired Network" tool used in Raspbian will not be functional.
If somehow the installation is unsuccessful, you can revert to the old setting by uninstalling NetworkManager:
sudo apt purge network-manager
then
sudo apt install dhcpcd5
