[SOLVED] Broadcom wireless on MacBook Pro 2013 not able to connect

Hi all,

Fresh off the Mac-boat newbie here, trying to get my head around Arch and Linux all in one go... I have unfortunately not been able to connect to any wireless networks yet. I have installed the proprietary Broadcom drivers (broadcom-wl-dkms), as it seems my chipset is not supported by the open source ones (BM4360).
Hardware profile:

$ lspci -vnn -d 14e4:
03:00.0 Network controller [0280]: Broadcom Limited BCM4360 802.11ac Wireless Network Adapter [14e4:43a0] (rev 03)
    Subsystem: Apple Inc. Device [106b:0134]
    Flags: bus master, fast devsel, latency 0, IRQ 18
    Memory at c1a00000 (64-bit, non-prefetchable) [size=32K]
    Memory at c1800000 (64-bit, non-prefetchable) [size=2M]
    Capabilities: <access denied>
    Kernel driver in use: wl
    Kernel modules: bcma, wl

ip link output:
2: wlp3s0: <NO-CARRIER,BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state DORMANT mode DORMANT group default qlen 1000
    link/ether ce:0f:3f:25:a9:4a brd ff:ff:ff:ff:ff:ff

When I run wifi-menu I see all the neigborhood networks, but when I try to connect to my own, there seems to be no way of getting it to work.

Output from systemctl:
$ systemctl --state=failed
  UNIT                                                              LOAD   ACTIVE SUB    DESCRIPTION             
● dhcpcd@wlp3s0.service                                             loaded failed failed dhcpcd on wlp3s0

wpa_supplicant also seems to be slightly unhappy about the whole thing. It is listed as running, but wpa_cli can't connect with it.

I am at my wits' end, and would be really grateful for a few pointers in the right direction!

Best,
K

How are you planning to control the card?  netctl? systemd-network? My suspicion is that you should not be enabling or starting the dhcpd service.  For almost all situations (except systemd-network) the dhcpcd deamon is started as needed by the appropriate service (netctl, NetworkManager, etc).

That your site survey works is good; your hardware is working.

What is the output of systemctl list-unit-files --state=enabled

So you are saying there might be conflicts somewhere in the system?
Here is the output of the systemctl query:
$ systemctl list-unit-files --state=enabled
UNIT FILE                                   STATE 
autovt@.service                             enabled
dbus-org.freedesktop.NetworkManager.service enabled
dbus-org.freedesktop.nm-dispatcher.service  enabled
dhcpcd.service                              enabled
dhcpcd@.service                             enabled
display-manager.service                     enabled
getty@.service                              enabled
NetworkManager-dispatcher.service           enabled
NetworkManager.service                      enabled
sddm.service                                enabled
remote-fs.target                            enabled

11 unit files listed.

Definitely a conflict.

There are many solutions to choose from, but remember that all of them are mutually exclusive; you should not run two daemons simultaneously.

You already have 4 network services enabled and all fighting over one device - 2x dhcpcd services and 2x NetworkManager services. Trying to use wifi-menu as well makes that 5.
Disable all of these services and then reboot, wifi-menu should now work.
