[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.
