Broadcom 4328 Network Device (Apple MacBook Mid 2007) not detected

Hi guys,

I posted this in the Newbie Corner, sorry for duplicating the post.

This is my first Arch Install and everything runs fine with wired network, these are the network devices listed (ethernet is not connected right now):

[usrname@archmachine ]$ ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc nonqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2. ens5: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_code1 state DOWN mode DEFAULT group default qlen 1000
    link/ether 00:1f:f3:d5:1c:c8 brd ff:ff:ff:ff:ff:ff
    altname enp3s0

Then if I look for the device using lspci, this is what I get:

 sudo lspci -vnn -d 14e4:
[usrname@archmachine ]$

             Kernel driver in use: b43-pci-bridge
             Kernel modules: ssb, wl

I have no output for rfkill list nor fkill unblock wifi or rfkill unblock all with or without sudo .
Also I have installed b43-firmware, and blacklisted everything, however, when I do iw dev list nothing appears.

Thanks in advance, and sorry if I didn't include any relevant stuff.

Your MacBook is way older than mine, but my Broadcom (4360) didn't work out of the box either.

If you read the corresponding section of the Wiki one tip is to use the driver "broadcom-wl", which worked for me (I use "broadcom-wl-dkms").

I blacklisted all other Broadcom modules:

/etc/modprobe.d/broadcom.conf:

blacklist b43
blacklist b43legacy
blacklist bcm43xx
blacklist bcma
blacklist brcm80211
blacklist brcmfmac
blacklist brcmsmac
blacklist ssb

Hi,

It is weird that it actually was solved after doing:

pacman -R broadcom-wl-dkms

and then blacklisting ssb, rebooting and following all the regular steps with iwctl.

Thanks!
