How to get WiFi working with BCM4360 (14e4:43a0) kernel 6.14.4-arch1-1

I installed Arch successfully, but I cannot make wifi work. I tried install broadcom-wl and broadcom-wl-dkms and modprobe it but after reboot it cannot boot with error. Please help me, thanks.

What can't boot with error, error do you get exactly?

Potentially

sudo journalctl -b-1

might help for context of a prior boot.
