• Wireless turning off at random times


    I’m running Antergos on my Lenovo Y520 laptop and for a while now an issue I used to have that had went away is now back. At any point whilst using the laptop, the wireless card will just turn off. It no longer shows up in ifconfig, and ip addr shows that its state is down.

    Output of dmesg | grep wlp2s0

    checking journalctl shows an error device (wlp2s0): supplicant interface state completed -> disabled, activated -> deactivating, deactivating -> disconnected and wlp2s0 link is not ready.

    It also has the error, connection disconnected (reason -3) I have no idea what the -3 error means.

    If anyone can point me in the right direction as to how I could fix this before sending it to a tech because the hardware might be fault that would be much appreciated.

    Lenovo Y520

    Your model should work according to this:
    https://wiki.archlinux.org/index.php/Laptop/Lenovo#Y_series

    So there may be many reasons why it no more works, at least one or many of:

    • hardware failure (I guess unlikely…)
    • wireless driver issues
    • kernel issues
    • power management issues

    One easy thing worth a go is try a different kernel. For example, if you are using package linux as the kernel, install and use linux-lts instead:

    sudo pacman -S linux-lts
    sudo pacman -S linux-lts-headers  # optional
    

    If that doesn’t help, check if you have the correct wireless driver.
    You could show some info about your machine with:

    lspci -vnn
    
  • @manuel I run the LTS kernel by default, and I’ve booted in both the LTS and latest kernels and the problem still persists. The problem is even worse as now the iwlwifi driver isnt loading automatically. And lspci doesnt show that a Network card exsits. I’m going to see if I can get it to show up again and properly load the driver.

  • @solacevii would be helpfull to get the full boot journal !

    System summery and bootlog example:

    lspci > log.txt && lsusb >> log.txt && journalctl -b -0 >> log.txt && cat log.txt | curl -F [email protected] https://ptpb.pw/?u=1

  • My laptop is dual booted with Windows. The wireless card isn’t detected their either. Leading me to believe this is a hardware issue.

    Also, today the wifi is working once again. If/when it shuts off again I’ll make sure to provide logs
    (Put in a new comment because editing wasn’t working.)

  • may wifi has a hardware switch?

  • As you already know, logs looking like there is no such hardware… an if it is unaviable under Windows too…

  • @solacevii
    Does Wifi work if you boot with the USB installer stick?

  • @manuel
    Nope. I unplugged and plugged back in the wireless card today and it’s working again. For the time being at least.

  • @solacevii
    OK.
    So: don’t fix it if it ain’t broken. ;)
