• No Wifi connection after last kernel update


    Hello,

    I’m a new user in this community and I have a problem after last system update.
    A few days ago, I decided to update my Antergos OS like I usually do every week, but this time after rebooting the system, I realised that my computer wasn’t able to connect to my Wifi network. I can see the networks, but not to connect to my network.
    One hour after, I figured out that the problem is (or seems to be) about the new Kernel version 4.11.3-1 or something related to it because with 4.10.13-1-ARCH the connection is all right.

    This is the dmesg log with the new kernel:

    Any idea? Someone else here have this problem?

    Thanks

  • Do you try to use LTS Kernel ? and yes there are some users with “no Wifi” after Kernel update…

  • Hello joekamprad,

    Thank you for your answer.
    No, I didn’t. That kernel seems to be prior in version to 4.10.13-1-ARCH, that is the kernel version I’m using at this moment.
    As a temporary workaround to the Wifi problem, I decided to downgrade the system to 20 of May, when the system was still OK. Then, through trial and error method, I saw that the problem was with the kernel update, so I excluded it from new updates in “/etc/pacman.conf”:
    “IgnorePkg = linux linux-headers linux-lts linux-lts-headers virtualbox-host-modules-arch”

    Finally, I have updated the whole system again (with those packages ignored).
    I decided to exclude all references to linux package (apart from virtualbox-host-modules-arch, which is a dependency). Is it OK? Really, I don’t know exactly what is the linux-lts for…

    Mainly, I’m worried because I don’t know if I will need to exclude that package “forever”, only until next update, or until when…?

  • LTS is the long term support kernel you can install side by side with the current one and choose on boot. More secure solution.
