    Default Wireless Adapter not detected any more after kernel update

    Hi!

    I am using Leap 15.1. After a recent kernel update, my network was suddenly disabled. It seems to me that there might be drivers missing, but I am not sure. I did not find any threads about this issue.

    Kernel version:
    Code:
    @linux-625c:~> uname -r
    4.12.14-lp151.28.40-default
    This is my output of lspci | grep network:
    Code:
    @linux-625c:~> sudo lspci | grep Network
    03:00.0 Network controller: Intel Corporation Dual Band Wireless-AC 3168NGW [Stone Peak] (rev 10)
    Output of lspci -n | grep rev\ 10:
    Code:
    @linux-625c:~> /sbin/lspci -n | grep rev\ 10
    03:00.0 0280: 8086:24fb (rev 10)
    Output of iwconfig:
    Code:
    @linux-625c:~> sudo iwconfig
    sudo iwconfig
    eth0      no wireless extensions.
    
    lo        no wireless extensions.
    Apparently, my wireless adapter is gone. This is what I got from dmesg | grep iwlwifi:
    Code:
    @linux-625c:~> dmesg | grep iwlwifi
    [    9.636653] iwlwifi 0000:03:00.0: loaded firmware version 29.1654887522.0 op_mode iwlmvm
    [    9.778266] iwlwifi 0000:03:00.0: Detected Intel(R) Dual Band Wireless AC 3168, REV=0x220
    [    9.801499] iwlwifi 0000:03:00.0: Can't parse phy_sku in B0, empty sections
    [    9.801504] iwlwifi 0000:03:00.0: Failed to read NVM: -61
    [    9.814851] iwlwifi 0000:03:00.0: Failed to run INIT ucode: -61

    I thought reinstalling the drivers might be worth a try, so I googled and found this:
    https://opensuse-guide.org/wlan.php

    I am not sure what to do next. Can anyone help me?

    The first thing should be to boot the previous kernel. It should be a grub menu option (usually via the submenu at the second menu line).

    If that works, then my suggestion would be to edit (as root) the file "/etc/zypp/zypp.conf". Look for the line that begins "multiversion.kernels" and change it to
    Code:
    multiversion.kernels = oldest,latest,latest-1,running
    That is, insert "oldest" in the list of kernels to keep. That way, the known working kernel won't be removed. You can change that back once there is a newer kernel that you know will work for you.

    That worked, many thanks for your help! :-)

    For the moment, I'll stick with that older kernel version then.

    I suggest you report a bug, or check if there is already a bug report for this. That way the openSUSE kernel team can start work on an updated kernel that fixes the problem.

    I already made a bugreport for TW, it's fixed in the current TW kernel and the kernels in Kernel:standard repo.

    This is bug http://bugzilla.suse.com/show_bug.cgi?id=1166632. When you boot via Grub, select the Alternatives and scroll down to the previous kernel 28.36. Am happily working away this way - the actual fix was made and tested within 48 hours and it is now in line for the next kernel update.
