Expected status of bwn driver in FreeBSD 15.0 with (Apple) BCM4322?

G

Geoff Buckingham

Does anybody actually have this working?
(My hardware is a 2010 13" Macbook Pro, Apple's propriety card format means swapping out for an intel wifi is a custom pcb project)
There are threads going back many years with varying outcomes, exact chipsets often not specified.

My experiance:
The man page is unhelpful monolithic kernel builds fail with path/include issues when BWN_GPL_PHY option included.

Building a module gets you close (driver attached, firmware loaded but erroring:

What version of FreeBSD?


While the FreeBSD kernel certainly is a monolithic kernel, dynamically loadable modules exist for a reason.

You don't need to build it yourself. It's already built.

FreeBSD 15.0 release (see title)

(I'll park building a static kernel including bwn & the BWN_GPL_PHY option as it's just a path issue of some kind and won't resove issues I'm seeing)

I have found no prebuilt modules compiled with BWN_GPL_PHY required to include the gpl code required for 'N'.

Trying to be clearer in my question. Does anybody have bwn working on BCM943224 , specifically the BCM94224PCIEBT found in ?some? 2008/2009/2010 Macbook Pros

I have found a 2024 report of working (unspecified freebsd vesion) wifi on a 2011 Macbook Air which also uses BCM943224 on a different board BCM94224PCIEBT2.
