I connect to the wi-fi network but I don't have internet

I have a problem:
I have installed Linux Parrot Security on a 2010 Mac Book computer, everything is working correctly except the WI-FI which, despite having the drivers installed correctly and correctly updated to the latest version, does not work.
When I select “connect to the wireless network” it gives me a message “THE CONNECTION HAS BEEN ESTABLISHED, now you are connected to the wireless network” But when I want to navigate NOTHING HAPPENS, it is as if I had no network connection.
I hope you can help me, I’m new to Linux and I’m super excited.
Thanks to everyone who has read me and to the people who help me. Hopefully soon I can help others.

Parrot version 5.3 Ara

Welcome to the forums,
the 2012 MacBook [from memory] came with a Broadcom 43*** series wi-fi, the drivers for this are available in the repository,
you will need to be connected to the internet [hard-wire or teatherd mobile]
open the software manager and search Broadcom or B43-fwcutter and install, as it installs it should pull the legacy B43 drivers from the archives.
