Wifi not recognised after new install

Post by rishiGhostMB »

Hi, I just installed GhostBSD 21.11.24 on a MacBook late 2011.
All went well, but WIFI adapter is not recognised.
What can I do to fix that ?
Details, see attachment.
Thanx in advance !

BCM4311 driver in FreeBSD source code.

Post by wb7odyfred »

Broadcom BCM 4331 chip 0x14e4 0x4311 is not supported in BSD. Broadcom is proprietary and does not release details on the internals to write a wifi driver. I see there is a driver for this chipset 4331 in the MAC Book Pro 8.1
Check bsd-hardware.info or linux-hardware.org for drivers.


https://github.com/freebsd/freebsd-src/ ... _bwn_pci.c freebsd-src/sys/dev/bwn/if_bwn.c

Might be a problem of NOT loading the firmware driver to the inside of the Broadcom WIFI chip. A line needs to be added to /boot/loader.conf

Can somebody confirm that GhostBSD supports FreeBSD wifi driver BCM4331 freebsd-src/sys/dev/bwn/if_bwn_pci.c Older MacBook Pros uses this Broadcom wifi chip 0x14e4 0x4331

It should be now, but there is a line that will need to be added in the loader.conf.

This driver requires firmware to be loaded before it will work.The ports/net/bwn-firmware-kmod port needs to be installed before ifconfig(8) will work. In most cases the bwn_v4_ucode kernel module from the port should be used. However, if an LP (low power) PHY is being used, the bwn_v4_lp_ucode module should be used. or maybe bwn_v4_n_ucode_load be used with BCM4322 chipset


in loader.conf

most likely bwn_v4_ucode_load="YES" like my imac.

With the new update I made yesterday, I got my iMac BCM4322 wifi working with net/bwn-firmware-kmod and bwn_v4_n_ucode_load="YES" in loader.conf.

Came across this post with detailed instructions on how to compile a kernel with BWN_GPL_PHY here:

I would expect there are licensing issues keeping it from being in the GENRIC kernel.

I copied bwn_v4_ucode.ko, bwn_v4_n_ucode.ko, and bwn_v4_lp_ucode.ko from the FreeBSD system to /boot/modules/ on my HelloSystem. The added lines to boot/loader.conf:


and etc/rc.conf:
create_args_wlan1="down country US"
ifconfig_wlan1="up scan WPA DHCP"
I was then able to shut the HelloSystem machine down, swap the wireless card, and have it come up working on the broadcom card:

ifconfig wlan1
