Can't connect to wifi after update (bcm4360 with broadcom-wl driver)

I was having the same problem, and it got solved by using the COPR build as suggested in Common F30 Bugs.

The working COPR repository is dcaratti/wpa_supplicant, and one can use it by running

sudo dnf copr enable dcaratti/wpa_supplicant
sudo dnf update

After reboot the issue will be solved
