[SOLVED] no wifi interface

Hi! Ive just made the pass from ubuntu to arch. Bought an old lenovo g470 and thought i could try

#iwconfig
enp1s0    no wireless extensions.

lo        no wireless extensions.

#lspci -k (parsing out other controllers)
02:00.0 Network controller: Broadcom Inc. and subsidiaries BCM4313 802.11bgn Wireless Network Adapter (rev 01)
    Subsystem: Broadcom Inc. and subsidiaries BCM4313 802.11bgn Wireless Network Adapter
    Kernel modules: bcma

ive tried following this post https://bbs.archlinux.org/viewtopic.php?id=195084 because it has the same controller, but i cannot disable any hidden network options, nor have a interface name

Re: [SOLVED] no wifi interface

What i understood was that i maybe bcma was being blacklisted, which it was not. Then i saw that i was using broadcom-wl actually, so i tried to pass to broadcom-wl-dkms but did not work either (wireless interface still does not show)

Re: [SOLVED] no wifi interface

The module is not loaded.  Either package provides the module, but you must then load it as clearly outlined in the wiki page you've already been linked to:

modprobe wl

Re: [SOLVED] no wifi interface

You clearly were using bcma before, what means it can not have been blacklisted and that's also not the concern of the posted wiki entry… so here're the important quotes from the wiki:

wiki wrote:

brcmsmac only supports old chipsets like BCM4313, BCM43224, BCM43225.

wiki wrote:

If using a brcm80211 driver be sure it has not been blacklisted. It should be blackisted if using a b43 driver.

Idk whether b43 supports the chip, but brcmsmac should™. Since it's a brcm80211 driver and you were using bcma, chances are brcmsmac got blacklisted, so fix that.

Re: [SOLVED] no wifi interface

$ cat /etc/modprob.d/blacklist.conf
# blacklist the speaker module to stop beeps
blacklist pcspkr

# blacklist known watchdog modules for faster boot/shutdown
blacklist iTCO_wdt

bcma is not blacklisted

i installed broadcom-wl with

$ pacman -Syu broadcom-wl

which is effectively installed

$ pacman -Qii broadcom-wl

$ modprobe wl

If i do 

modprobe broadcom

i get no output, but it is the only wireless driver that modprobe is recognizing.
I have also tried all the above with broadcom-wl-dkms (removing confliting packages when neccesary) and had the same results

I know im new to arch, but i really do want to learn
thanks for the help

Re: [SOLVED] no wifi interface

If your wireless hardware can use the brcmsmac driver, you should really work on that first.  wl should be considered a near last resort, but it will work for your hardware.  The problem in your last output is pretty clear: you are running an old kernel.  Either reboot into the current kernel, or replace the broadcom-wl package with broadcom-wl-dkms (which you previously claimed to be already have installed ... so frankly I'm confused by your last post).

broadcom-wl provides the module for the linux kernel not the linux-lts kernel.

Re: [SOLVED] no wifi interface

broadcom-wl-dkms ensure you have linux-lts-headers installed.
When you install the packages with pacman the DKMS hook will generate a module for every kernel with headers present.
If the hook fails post the output from that pacman command.  If not try `modprobe wl` again after installing the packages.

Re: [SOLVED] no wifi interface

This is all covered in the previously linked wiki page which you still clearly have not read.

Sadly at the moment it may not be readable, as the wiki content is (hopefully temporarily) gone.
