Help with installing broadcom-wl offline archiso

zachdr1 · 2017-04-21 01:42:02

I'm trying to install Arch on one of my other computers, but I need to get broadcom-wl which depends on linux-headers in order to get internet connection.

I have downloaded https://www.archlinux.org/packages/core … x-headers/ and https://aur.archlinux.org/packages/broadcom-wl/ onto the flash drive that I'm using to install arch, and I can untar broadcom-wl fine, but when I untar linux-headers I am left with a directory called usr and I can't find the pkgbuild. From my understanding I am supposed to build both packages on another computer and then install them on the live cd while on the computer I'm trying to install arch on.

Could someone help me figure this out?

Thanks

The file you've downloaded was probably a .pkg.tar.xz, which is already a built package, so you can simply use `pacman -U` to install it.

You also don't need linux-headers installed on the iso unless you want to build broadcom-wl on the iso. If you can build the broadcom-wl on another computer you only need to get the broadcom-wl-*.pkg.tar.gz file to the usb and install it with `pacman -U`. Linux-headers are a build dep only.

You *will* however have to build broadcom-wl against the same kernel version as is used on the iso.

Ohhh okay, so where in the installation process should I do this? This is the first time I've had to deal with firmware during an installation.

And just to make sure I'm doing this right, to build broadcom-wl, all I do is go into the directory with the pkgbuild and use the command makepkg right?

At the beginning, so you can have a network connection. You'll likely also need to load the wl module (`modprobe wl`) and perhaps rmmod others as described in the wiki.

Pretty much. `makepkg -s` would also install the dependencies before building the package.

So I got broadcom-wl installed on the iso and I entered the modprobe and rmmod commands, but I still can't access the internet. I think I'm probably just missing a step

Loading the module only made the system see the wireless network interface/card—you still have to configure the network (see https://wiki.archlinux.org/index.php/Wi … iguration).

Yeah I tried reading the wiki but it seems that my computer still isnt recognizing the interface. ip link only shows lo, and iw dev shows nothing. My network controller is BCM4360

Thanks for all the help btw

That's odd—what's the output of these commands?

lsmod | grep wl
lsmod | grep b43

output of lsmod | grep wl

wl 6377472 o
cfg80211 524288 2 wl,mac80211

there is no output for b43

loqs · 2017-04-21 23:01:17

The output of the following please

$ dmesg | grep wl
$ ip link

I don't get anything with the first command, and for the second I get

The wl module was loaded when you ran that command?

I haven't done anything after installing wl, but as far as I know it was loaded.

As long as it shows in the output of lsmod it is loaded it just seems odd there is no output in dmesg from the wl module. Would expect something similar to:

[    7.937658] wl: loading out-of-tree module taints kernel.
[    7.937661] wl: module license 'Mixed/Proprietary' taints kernel.
[    7.986067] wl 0000:0a:00.0: enabling device (0100 -> 0102)
[    8.014197] wlan0: Broadcom BCM4359 802.11 Hybrid Wireless Controller 6.30.223.271 (r587334)
[    8.015541] wl 0000:0a:00.0 wlp10s0: renamed from wlan0

What wireless adapter is it? You should be able to obtain the output from `lspci -nkk` for a pci device and `lsusb` for a usb device the VID:PID of the device is preferable to a device name. For broadcom the VID should be 14e4.

I actually don't see it in the output of lsmod, but I know I definitely installed it. And the VID:PID is 14e4:43a0.

Actually I just reinstalled wl and ran the dmesg command again and I got output

 wl: loading out-of--tree module taints kernel.
wl: module license 'Mixed/Proprietary' taints kernel

but I still have the same output for ip link

EDIT: So I got it to work, but it was completely by mistake and I have no idea why it works but I have to go through this long process every time, so I'm hoping someone could tell me what I did to fix it so I don't have to go through this whole process every time.

Here's what I did to fix it:
I installed

 
dkms-2.3-2any.pkg.tar
gcc-6.3.1--2-x86_64.pkg.tar
guile-2.0.14-1-x86_64.pkg.tar
libmpc-1.0.3-2-x86.pkg.tar
make-4.2.1-1-x86_64.pkg.tar
patch-2.7.5-1-x86_64.pkg.tar
binutils-2.28.0-2-x86_64.pkg.tar.xz
libtool-2.4.6-7-x86_64.pkg.tar.xz

which were all dependents of

dkms-2.3-2-any.pkg.tar

I installed dkms then I installed

broadcom-wl-dkms-6.30.223.271-11-x86.pkg.tar

and ran the commands

rmmod b43 b43legacy ssb bcm43xx brcm80211 brcmfmac brcmsmac bcma wl
modprobe wl

but this DID NOT make the interface show up in ip link

So I replaced broadcom-wl-dkms with broadcom-wl using

pacman -U broadcom-wl-6.30.223.271-4-x86_64.pkg.tar.xz 
modprobe wl

AND NOW IT WORKS

I just have no idea why and I don't want to have to do this every time I reboot my computer.

If I get it correctly, you're doing all of this in the installation ISO, so all of this just happens in RAM (no changes to the live system are persistent). So yes, everytime you reboot, you have to redo all of this.
However, once you've managed to install the system to a persistent storage (e.g. your computer's hard drive), there is no need to do this at every boot.

Cool, do you have any idea why this method worked, but installing broadcom-wl didn't? I said that the dkms variant didn't work, but thats just because I had no idea where to get the ARCH files from that I needed for dkms; I tried researching, and I downloaded linux headers, but I guess they weren't the right ones.
