Wifi Issues on MBP Mid 2015 -- firmware issue?

zincbot · 2020-05-27 20:07:58

I installed Arch with the 5.4.42-1-lts kernel on a Macbook Pro 2015 a few days ago. Since, I've been having issues with my wireless card.

HARDWARE & INTERFACE:

Here's what I'm working with:

> lspci -k

...
03:00.0 Network controller: Broadcom Inc. and subsidiaries BCM43602 802.11ac Wireless LAN SoC (rev 01)
	Subsystem: Apple Inc. BCM43602 802.11ac Wireless LAN SoC
	Kernel driver in use: brcmfmac
	Kernel modules: brcmfmac
...

> ip l

...
3: wlp3s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_codel state DOWN mode DEFAULT group default qlen 1000
    link/ether 12:9e:77:xx:xx:xx brd ff:ff:ff:ff:ff:ff
...

SYMPTOMS / CONTEXT:

Just want to join my LAN.

1. The first red flag is that I can't bring the interface up.

> sudo ip l set wlp3s0 up # no error is generated
> ip l

...
3: wlp3s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_codel state DOWN mode DEFAULT group default qlen 1000
    link/ether 12:9e:77:xx:xx:xx brd ff:ff:ff:ff:ff:ff
...

2. Can't start wpa_supplicant either (and network manager correspondingly doesn't work)

> wpa_supplicant -iwlp3s0 -c /etc/wpa_supplicant/wpa_supplicant.conf -d

...
mkdir[ctrl_interface="/run/wpa_supplicant/"]: No such file or directory
Failed to initialize control interface '"/run/wpa_supplicant/"';.
You may have another wpa_supplicant process already running or the file was
left by an unclean termination of wpa_supplicant in which case you will need
to manually remove this file before starting wpa_supplicant again.

Failed to add interface wlp3s0
...

I disabled Network Manager and killed wpa_supplicant for the test above.

Interestingly enough, I can scan with:

> sudo iw dev wlp3s0 scan

DEBUGGING:

The interface didn't show up until I installed the "linux-firmware" package. This package was like 512 Mb of random drivers. : ( This put "brcmfmac43602-pcie.bin" and "brcmfmac43602-pcie.ap.bin" in "/lib/firmware/brcm". Also installed "broadcom-wl" per the wiki.

It looks like it's still missing some files:

> dmesg | grep brcm

[   50.611078] usbcore: registered new interface driver brcmfmac
[   50.773906] brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac43602-pcie for chip BCM43602/1

[   51.467236] brcmfmac 0000:03:00.0 wlp3s0: renamed from wlan0

I figure that "brcmfmac43602-pcie.Apple Inc.-MacBookPro11,4.txt" and "brcm/brcmfmac43602-pcie.txt" were Apple specific configurations or firmware settings. I would think these files would be proprietary and protected by the system. Yet, it seems that some people have these files or similar firmware for other models.
- https://github.com/stefanpartheym/mbp15 … iver-files (firmware for newer model)
- https://askubuntu.com/questions/907489/ … s-pce-ac88 (has brcm/brcmfmac43602-pcie.txt)

I don't know how Stefan got the divers.

The journal also shows some interesting behavior. I've included exerps from Network Manager.

RESOURCES:

1. https://wiki.archlinux.org/index.php/Ma … 11,x#HiDPI
- Lists the wifi as not functional. Don't know if that means out of the box or with the avalible packages from the AUR. Seems unstable.
2. https://forum.manjaro.org/t/solved-bcm4 … -rt/105970

Seems like the wireless card is missing something that makes it unstable. Is this feudal exercise? If it is, hope this helps someone. If not, thoughts on how I could proceed? I appreciate any and all help.

Please post outputs in [ code ] [ /code ] tags without the spaces.

You are correct that broadcom chipsets often have issues with the free drivers, there exists a proprietary driver by broadcom though: https://wiki.archlinux.org/index.php/Br … roadcom-wl that tends to be more stable. If you continue to stay on LTS you will have to install the linux-lts-header and the -dkms variant of this driver.

Edit: Ah just gone through the walls of outputs, you've identified that already, but yes the current issue is that you did not install the correct broadcom-wl driver for your kernel.

Btw linux-firmware can be necessary for all sorts of hardware/drivers you almost always want it on bare-metal installations.

Thanks for the feedback. Very helpful.

Already had linux-lts-headers installed. I ran:

> sudo pacman -S dkms broadcom-wl-dkms

This removed broadcom-wl automagically.

I removed conflicting modules as it suggested:

> sudo rmmod b43 b43legacy bcm43xx bcma brcm80211 brcmfmac brcmsmac ssb wl

And added it:

> sudo modprobe wl

Curiously, wlp3s0 disappeared from "ip l". I removed broadcom-wl-dkms and restarted and the interface reappeared.

There's nothing in dmsg about firmware, brcm, or wlp3s0. Reinstalled it and I saw wl fail:

[   19.180735] wl: loading out-of-tree module taints kernel.
[   19.180739] wl: module license 'MIXED/Proprietary' taints kernel.

This looks like the same issue: https://bbs.archlinux.org/viewtopic.php?id=220734

Tried to install broadcom-wl-lts but ran into errors while building.

https://aur.archlinux.org/packages/broadcom-wl-lts/ has not been updated since 2016-12-16, it requires the existance of /usr/lib/modules/extramodules-5.4-lts/ which linux-lts does not supply.
It is also missing patches for kernel changes since the driver was produced by broadcom https://git.archlinux.org/svntogit/comm … om-wl-dkms
Edit:
If you reinstall broadcom-wl-dkms then reboot does it still produce the same error?

That's unfortunate.

Yep. I get "wl driver 6.30.223.271 (r587334) failed with code 1". I'm guessing the interface isn't initialized because the driver I've added failed. Is there any way to debug a proprietary driver?

Edit: Also, could I download the driver from the upstream and install it myself? If so, I can't find the BRCM43602 driver on the upstream for broadcom-wl.
