[SOLVED]Wifi Stopped Working after Kernel Update on Macbook pro 11,4

lepark · 2024-07-30 07:14:47

Hello everyone! I'll get to the point, installed archlinux using archinstall script on a macbook pro 2015 on Janury 2024, and since then i haven't experienced any hardware issue; but 5 days ago (at the time I'm writing the post) the wifi stopped working after applying a kernel update and by stopping I mean I have the possibility to scan wifi networks but is not possible to connect to any network and actually this post describes very well my issue:

https://bbs.archlinux.org/viewtopic.php?id=201944

I've tried everything that i could find over the web such as blacklisting other possible conflicting modules like b43,ssd,wl by creating a file as the following page states:
https://wiki.archlinux.org/title/Kernel … probe.d/_2 but had no luck.

Then I tried disabling Mac randomization using this guide https://wiki.archlinux.org/title/Networ … domization without any luck either.

Also changing the transmission power of the BCM43602 using the following command makes no difference, the command i got it from another post here in the arch forum:

sudo iwconfig wlp2s0 txpower 10dBm

Link: https://bbs.archlinux.org/viewtopic.php?id=291889

I know for sure the wifi card is working since I reinstalled macOS and it was working perfectly, then tried to reinstall again archlinux and the issue persist. Also reading the official link for macbook pro11,x archlinux, its mentioned that "broadcom-wl or broadcom-wl-dkms works" but didnt have any lucky on both.

Running

sudo dmesg | grep brcmfmac

Provides this output:

The information about my Wireless Card is the following (I ran lspci -vnn -d 14e4);

03:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM43602 802.11ac Wireless LAN SoC [14e4:43ba] (rev 01)

The reason i decided to stick to brcmfmac is beacause my card appears on the supported hardware list on https://wireless.wiki.kernel.org/en/use … /brcm80211.

Does downgrading the "linux" package or switching to "linux-lts" help?

lepark · 2024-07-30 07:36:41

Hello gromit!, sadly no the same issue persists even with LTS Kernel: 6.6.42-1-lts . Haven't tested downgrading the Kernel yet... do you think that might make a difference?

Yes it could be that the same fix backported to both stables series broke your device ... although that does not happen very often ..

Did you also check what other packages were upgraded in the same timeframe? Maybe linux-firmware or similar?

"ip a", and see https://bbs.archlinux.org/viewtopic.php?id=298025

hi i have the same laptop and i had the same problem. downgrading to `wpa_suplicant2:2-10:8` fixed it

I can confirm that this also resolved it for me. Too bad I had to figure it out myself before finding this post! heh.

As for a permanent fix, I wonder if we'd need to make a tweak to the https://gist.github.com/cristianmiranda … 2-pcie-txt file somehow to get it compatible with the latest `wpa_supplicant`.

Some additional info regarding the mention of the kernel breaking this. The kernel didn't break this, but `6.10.2` did break the `apple_ib_tb` module (last working version was `6.9.9`), so I changed to the LTS kernel (`6.6.42`) for the time being. Is your touch bar working with `6.10`? If not, perhaps we should create a new post discussing that further and not take this post off topic.

Thanks,

EDIT: Apologies seth, I've just jumped onto the thread you linked and there is a whole wide discussion about it and that wpa_supplicant 2.11 is working again for these Broadcom Chips. Sorry about that, moving along!

Hello Everyone! Sorry for answering a bit late and thank you @gromit & @seth for helping me. Yes I can confirm downgrading the package fix the issue, just leaving what I have done in case someone in the future find it helpful.

1. Get the package ( I got wpa_supplicant-2_2.10-8 ) from https://archive.archlinux.org/packages/ … upplicant/

And just do:

sudo pacman -U package

In order to avoid updating the package while this get fix I added the exception to pacman so this package will be ignored:

sudo nano /etc/pacman.conf

Look for this lines and add "wpa_supplicant":

# Pacman won't upgrade packages listed in IgnorePkg and members of IgnoreGroup
IgnorePkg   = wpa_supplicant

Just in case I restarted the following services:

sudo systemctl restart wpa_supplicant
sudo systemctl restart NetworkManager

sudo systemctl restart wpa_supplicant
sudo systemctl restart NetworkManager

You should absolutely not have wpa_supplicant enebaled if you're using NM - NM invokes wpa_supplicant itself

Sorry my bad, so we should only restart

sudo systemctl restart NetworkManager
