• wifi issue


    Hello guys I need help again. Just now I was working on my laptop and then after connecting usb stick my wifi suddenly disappeared. Nothing changed after reboot and there’s no wifi in Settings -> Network. Here are some outputs

    $ ip link show
    1: lo:  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
    2: enp7s0:  mtu 1500 qdisc fq_codel state DOWN mode DEFAULT group default qlen 1000
        link/ether d4:be:d9:3c:95:f5 brd ff:ff:ff:ff:ff:ff
    
    $ dmesg | grep firmware

    $ lspci -nnk |grep -A2 0280

    	Subsystem: Dell Wireless 1704 802.11n + BT 4.0 [1028:0016]
    	Kernel modules: bcma, wl
    

    Can anyone explain what happened and how to fix it?

  • Did you update your kernel?

  • Well, I upgrade my system regularly, so maybe I did. My current kernel version is 4.2.4-1. Should I downgrade?

  • Hi,

    It might be that your broadcom wifi driver has not been updated along with your kernel. Can you issue a dmesg command again without the grep filtering?

  • Try installing broadcom-wl (it’s the closed broadcom driver).

    sudo pacman -S broadcom-wl

  • @karasu yeah, it helped, thanks. So can you explain what actually happened, so I would know how to fix it myself next time

  • With each kernel update, your wifi driver needs an update, too.

    I’m afraid you will have to remember it and do it manually.

    There’s another option, and that is to remove broadcom-wl and install an AUR package called broadcom-wl-dkms (this will install dkms, too). dkms takes care of updating kernel drivers without your intervention. (I prefer to not to use dkms and take care of it myself… but do what suits you, of course).

    Cheers!

  • @karasu ah, I see, thanks for your help :blush:
