[SOLVED] No networking interfaces after upgrade

broadkahm · 2014-08-18 11:23:41

After a recent upgrade on Thursday, I no longer have any networking devices recognised. I'm running a macbook air 2011 and have had no networking problems since my change to the 'broadcom-wl' drivers from the AUR three weeks ago. After rebooting from the upgrades, wifi-menu gave me an error saying "Invalid interface specification". and when i do specify wlp2s0, "no such interface"

iwconfig gives me

lo    no wireless extensions

and that's it. I'm pretty sure there used to be wlp2s0 there.

Thanks in advance for your help and let me know if you need more info/outputs. (this may take a while because I need to boot in that partition and copy paste the outputs on a usb, etc.

Compare the outputs of uname -a and of pacman -Qi linux
Compare the version numbers they report. Is the running kernel (uname -a) the exact same revision as the one that is installed (pacman -Qi linux) ?

broadkahm · 2014-08-18 16:09:04

uname -a

Linux 3.16.0-2-ARCH #1 SMP PREEMPT Mon Aug 4 19:04:45 CEST 2014 x86_64 GNU/Linux

pacman -Qi linux

linux 3.16-2

that's the same right? also, for the output of pacman -Qi linux, there is "required by: broadcom-wl" which may be relevant to what I'm dealing with.

Yes, you are good as to the kernel. A common problem is for the wrong kernel to be loaded at boot for a variety of reasons that are not applicable here.

What are the output of ip link and of iw list ?

broadkahm · 2014-08-18 16:27:36

ip link

 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

iw list

nothing

Can you post the output of dmesg ?
It is huge, so it is better to post it to a site like bpaste or pastebin. Without network, this could be problematic. Can you write to a USB drive?

Also, if you have a smart phone, you might try associating it with your wifi, connecting to your computer via USB, enable USB tether, and, if all goes well, a "Wired" interface should appear on your machine. If it does, just run dhcpcd and you should have connection through your wifi (not your data plan)

broadkahm · 2014-08-18 16:59:56

my xterm doesn't have enough lines to display all of dmesg's output. is there a way to export the text to a .txt file? dmesg --help didn't show any such option

i would have to copy to usb most likely. your recommended method of using a smartphone sounds great, but my internet situation at the moment is a bit tricky since i just moved. (one device for wifi at a time, login necessary, using my thinkpad R61 right now)

thanks for your assistance.

There is absolutely nothing in there about networks. That is bizarre.

As a sanity check, what is the output of lspci

broadkahm · 2014-08-18 19:50:54

That is bizarre.

wow. glad i'm not just bad at solving problems.

here is lspci... looks like the network controller is indeed there.

I've managed to downgrade the kernel, and everything works fine again.

But even after upgrading to the newer kernel (linux 3.16.0 to linux 3.16.1), it still causes this problem.

Any other macbook users with broadcom-wl experiencing this as well?

LeonardK · 2014-09-03 17:11:14

Im not using a Macbook (but an Acer Aspire V3-571G) and I have the same issue on this Laptop.
The card I am using is:
BCM9 43228 HM4L.

Actually you are in the luckier position as you dont *need* to use the reverse-engineered drivers (b43 or broadcom-wl) as I am. You can use the (fully opensource) broadcom drivers:

https://wiki.archlinux.org/index.php/br … 2Fbrcmfmac

Atleast your card is listed here:
http://wireless.kernel.org/en/users/Dri … rted_Chips

Hope this helps

LeonardK · 2014-09-03 17:17:12

Additionally you might try lspci -k for showing which driver handles the interface (maybe it's not the one you want)

Every kernel update breaks broadcom-wl on my Macbook Air early 2014.

What I'm doing:

1. Unistall broadcom-wl
2. Rebuild broadcom-wl
3. Start wifi-menu to get connection

Can somebody point me in the right direction on what it means to "rebuild" broadcom-wl?

That was my suspicion from the start: you need to manage AUR packages yourself. To rebuild it, just do exactly what you did to initially install it. Download the aur tarball, extract it, cd into the directory, then `makepkg -i`. Depending on whether you use an aur helper the exact steps might vary.

Thank you.

My Macbook Air 2011 model basically broke the networking with the unnecessary broadcom-wl driver. Simply uninstalling broadcom-wl it and rebooting after a kernel upgrade has everything working perfectly again.

@Fixed's method will help me in the future if I again begin to get dropped connections using the default driver.

And thanks for the help with rebuilding packages @Trilby
