Is this not already provided by the broadcom-sta package?

On my Macbook Pro 2013 it is

Personally I have had a lot of trouble with broadcom-sta and it doesn't seem to work for BCM4360, if you have a solution please tell me tho

Just converted my 2009 Macbook from Arch. Its wifi was working fine for years with broadcom-wl-dkms, not working with:

boot = {
    kernelModules = [ "kvm-intel" "wl" "b43" ];
    extraModulePackages = [ config.boot.kernelPackages.broadcom_sta ];
};

The respective wpa_supplicant journald entry is spammed with CTRL-EVENT-SCAN-FAILED ret=-22 retry=1.

$ sudo dmesg | grep -i wireless
[   19.357094] eth0: Broadcom BCM432b 802.11 Hybrid Wireless Controller 6.30.223.271 (r587334)

Hi @n8henrie

I was having the same message spammed as well. I switched from wpa_supplicant to network manager and now it seems to work.

{
boot = {
    kernelModules = [ "kvm-intel" "wl" ];
    extraModulePackages = [ config.boot.kernelPackages.broadcom_sta ];
};

networking.wireless.enable = false;
networking.networkmanager.enable = true;
}

I'm not entirely sure why this worked for me, since networkmanager uses wpa_supplicant under the hood. Also, I think it started working when I toggled 'flight mode' in Gnome.

Hopefully this helps!

[n8henrie]

Thanks for the heads up!

For no reason in particular I'm not a huge fan of NetworkManager, but I tried it and had the same experience -- it worked well. That made me curious, so I tinkered a bit today and was able to get things working well by removing extraModulePackages = [config.boot.kernelPackages.broadcom_sta];, so the relevant parts of my config are currently:

networking = {
    wireless.enable = true;
    enableB43Firmware = true;
};
boot.kernelModules = ["kvm-intel" "wl" "b43"];

Also, as @ReplayCoding mentioned, I looked into things and it looks like nixpkgs already has basically the same patches as broadcom-wl-dkms.

For example, here is the source from the broadcom-wl-dkms arch package I had previously been using: https://github.com/archlinux/svntogit-community/tree/packages/broadcom-wl-dkms/trunk (the repo linked by OP looks like it's actually outdated compared to this).

Compare those patches to https://github.com/NixOS/nixpkgs/tree/master/pkgs/os-specific/linux/broadcom-sta -- the commits there even reference broadcom-wl-dkms: https://github.com/NixOS/nixpkgs/blob/master/pkgs/os-specific/linux/broadcom-sta/linux-6.1.patch

So in short, I think @johnk1917 can close this issue, as the package he's requesting is already implemented AFAIK.

Right now I'm trying to get BCM4360 (PCI card) working with wpa_supplicant with no success. With config you provided ip doesn't ouput card at all.

[MrFoxPro]

Btw iwd works fine with BCM4360

@MrFoxPro interesting. I'm over my depth, but interesting that we have different kernel drivers / modules in use:

Possibly hardware is different, I have PCI card with this chip, and I guess you are using macbook

Maybe this thread might help: https://discourse.nixos.org/t/wifi-problems-only-after-installation/27969

I'm still looking for a solution on my old iMac. I have submitted a PR #1089 against NixOS/nixos-hardware to add the iMac, I also added a note regarding the Wifi, feel free to suggest how this could be fixed.
