[Temporarily Fixed] WiFi not working on 2015 MacBook Pro

The same old problem with Broadcom Wireless on Linux. I have a 2015 MacBook Pro which uses a Broadcom BCM43602 WiFi chip. Since I upgraded from the 6.10.7-arch1-1 kernel to the newer version (6.10.10-arch1-1) the WiFi is working weirdly.

I can see all the networks listed in NetworkManager and IWD, but the connection is not working. It gives me a 'Wrong Password' prompt, even if I've double-checked that it got typed out correctly. I've ruled out everything; it works in other distros, and it used to work on the Arch Installation USB, I've even resulted in installing Linux-LTS and recompiled the kernel multiple times. WPS also does not appear to work.

What else can I do? It's really not at all convenient to keep my phone plugged in so that I can use USB tethering or an ethernet adapter. It's a laptop with 2 USB ports, after all

Re: [Temporarily Fixed] WiFi not working on 2015 MacBook Pro

After some troubleshooting and some additional searching within the forum, I figured out that there's a bug on WPA Supplicant. The temporary solution is to downgrade to the last working version, by using this command:

sudo pacman -U https://archive.archlinux.org/packages/w/wpa_supplicant/wpa_supplicant-2%3A2.10-8-x86_64.pkg.tar.zst

Then, to prevent this package from being updated/upgraded, include WPA Supplicant to your Pacman IgnorePkg parameter on the /etc/pacman.conf file, by editing line 25 like so:

IgnorePkg   = wpa_supplicant

As this is more like a temporary solution than a permanent fix, I'm not adding a Solved tag, but rather a Temporarily Fixed one.

Hi there, sorry for the late reply

Unfortunately, this did not fix the problem for me

Is there any other potential solution?

We'll first need to idetify it then, please post your complete system journal for an affected boot eg.:

sudo journalctl -b -1 | curl -F 'file=@-' 0x0.st

for the previous one.
