No longer detects wifi card

General system Kernel, boot, graphics & hardware
1

Hello,

I was using my laptop and the battery drained and then powered off

When I started to charge it again it no longer detects wifi or a wifi card

I did do a pacman update a hour before the event so not sure if that actually caused an issue

I’m on a Macbook Air 2012

when I do ip link - it only shows:
1: Lo <LOOPBACK,UP>

wifi-menu runs but with
invalid interface specifications

lspci -k | grep -A 2 -i network
02:00.0 Network controller [0280]: Broadcom Inc… AIrpOrt Extreme [106b.009e]

rfkill
only shows bluetooth

It seems to be the broadcom with kernel 10 update, a solution is there.

EDIT:

wifi-menu runs but with
invalid interface specifications

could you give the result of:

Do you use 2.4Ghz or 5Ghz ?
Need to check about this BCM43224…

currently I’m on 5GHZ

My phone is still conneced to wifi

Is there any other troubleshooting steps I should take?

@shodan
Try installing broadcom-wl and reboot.

Did you see this from the @Shjim link ?

Device inaccessible after kernel upgrade

Since the 3.3.1 kernel the bcma module was introduced. If using a brcm80211 driver be sure it has not been blacklisted. It should be blackisted if using a b43 driver.

If you are using broadcom-wl, uninstall and reinstall it after upgrading your kernel or switch to broadcom-wl-dkms package.

The broadcom-wl-dkms is not working anymore for me on 3 computers on the 5.10.3 kernel. I had to revert to the broadcom-wl and it works. The broadcom-wl-dkms doesn’t work after a subsequent reboot. My chips are the Broadcom BCM4360 though.

ran sudo modprobe brcmsmac

wifi came back online

made a change to my grub

modprobe.blacklist=wl modprobe=brcmsmac

rebooted and wifi is enabled

I’ll try your additional steps

14

now my laptop random freezes/locks

Happened a half dozen times while browsing the web

15

I uninstalled broadcom-ws
installed broadcom-ws-dkms

I removed the grub blacklist and mapprobe entry I posted above

I’ll see if this resolves the freezes/locking out issue as well

This is one way to spend my day off
troubleshooting an linux update and learning emacs…

I uninstalled broadcom-ws
installed broadcom-ws-dkms

To be sure you meant broadcom-wl and not broadcom-ws ?

It seems that there is a bug report https://bugs.archlinux.org/task/69065?project=5&string=broadcom-wl a new one is in testing due to kernel 10 !

With the Broadcom BCM43224 and update kernel it seems to not be new !
Solution for now could be the one that experienced @ricklinux in installing the broadcom-wl

https://bbs.archlinux.org/viewtopic.php?id=130071

Give the result from:

rfkill list
17

I only reason i suggested this is because if they had the broadcom-wl-dkms installed before and it was working then it should work with the broadcom-wl as this is what i have experienced. You have to reboot after installing it.

18

I mean
broadcom-wl-dkms and not broadcom-ws

rfkill
ID TYPE DEVICE SOFT HARD
0 wlan phy0 unblocked unblocked
1 bluetooth hci0 unblocked unblocked

my wifi is working now but the laptop randomly freezes/locks
happened so far when I was browsing the web with Brave

I uninstalled my VPN and testing without it for an hour

Going to re-install my VPN and now see if the occurs occurs

Try this:

sudo rmmod b43 b43legacy ssb brcm80211 brcmfmac brcmsmac bcma wl

sudo modprobe b43 allhwsupport=1

If that improves things, then create the following file:

/etc/ modprobe.d/ b43.conf

Add the following contents to the conf file:

blacklist wl
blacklist brcmsmac
options b43 allhwsupport=1

Reboot.

Hey there @shodan. I posted my suggestion to you 3 days ago, and I see you were online yesterday. The two terminal commands I asked you to run takes all of 5 seconds effort. Generally when someone is kind enough to go out of their way to compose a detailed reply for someone who is requesting help the courteous thing to do is to at least acknowledge their effort to help.

When users ignore my suggestions or fail to provide feedback to my suggestions, I generaly tend tend to respond in kind by ignoring that users requests for help in the future.

I can’t speak for others, but I personally find that type of behaviour totally lacking in courtesy towards those kind enough to come to your assistance. IMO whether a suggestion helps (or not) you should always acknowledge it, and provide feedback as to whether the suggestion worked. This helps others in the future searching for solutions to similar problems, and is just the polite thing to do.

Then again, perhaps I am just too old to accept the fact that common courtesy is no longer a common occurance in this day and age.
