Troubled Wi Fi on Macbook

Hi everyone, I installed fedora 33 on a macbook pro late 2011. Then I followed these instructions because the wi fi driver wasn’t installed by default Eric D. Schabell: Installing Fedora 33 on Macbook Pro 13 inch (late 2011)

Now the wifi works but the connection, if the router is not close, is not as stable as what it used to be with mac osx. It also has some problems and is very slow when connecting for the first time or reconnecting after an interruption.

Is there something I can do?
