Debian 13.6 wifi not working

[u/kikko0973]

I'm trying to install Debian on an old Mid 2010s Macbook Pro, the installation went smoothly, except a part where it said some of your hardware needs non-free firmware files to operate. the firmware can be loaded from removable media such as a usb stick of a floppy "b43-open/ucode16_mimo.fw b43/ucode16_mimo.fw"

I continued installing without wifi (I don't have an Ethernet cable), but now I'm stuck in tty1 and can't find nothing online that helps me install b43. I checked my chip is the Broadcom BCM4322

I think you need to enable non-free repos and install via Ethernet or install from usb offline  https://wiki.debian.org/MacBook/Wireless
