Enabling bwn in FreeBSD

Question

I am trying to load the bwn driver as a module as mentioned in the man page.

However, when I attempted to edit /boot/defaults/loader.conf I could not write the changes to the file, this was attempted as root.

Then I read that this file is not to be edited. How can I load this driver as a module?

Answer 1

You need to put if_bwn_load="yes" in /boot/loader.conf. If you don't have a /boot/loader.conf file on your system, just create it. As with the /etc/defaults/rc.conf file, /boot/defaults/loader.conf contains default values that can be overridden in a per-system fashion.

Of course, you'll need to either reboot the system to pick up the new setting, or load the module manually the first time with kldload if_bwn.
