Thread: iwlwifi broken on Kernel 5.3.18 (and 5.10.rc2) - Wifi lost/unstable for Intel Wireless 3160

    Default iwlwifi broken on Kernel 5.3.18 (and 5.10.rc2) - Wifi lost/unstable for Intel Wireless 3160

    Hello.

    I am experiencing heavy trouble on wifi lately. I didi some research and I came to conclusion kernel/firmware support for Intel Wireless card has been broken somehow.
    It started with unstability (sudden disconnection) and ended up with NO wlan0 interface (things may vary upon setup/config).
    The best I obtained was a couple minutes of ping working (and included tinkering with iwlwifi,conf )

    I tried many things, even thinking almost for sure my card was physically damaged.
    Since I had a problem with a partition, after the problem, I reinstalled using a Leap 15.0 USB key I spared (Kernel 4.xx) and... Wifi started to work again!

    When I upgraded to 15.2 (latest with zypper) the problem happened again. Wifi unusable. I miracoulously came up with a cable and connected with Ethernet now.

    I also tried using latest kernel (as a few days ago), now on 5.10.0-rc2-1.ga51c4bb-default x86_64 and having similar situation: wifi disappeared. (kernel-firmware updated with canditate proposed)
    Dmesg shows various troubles on iwlwifi.
    I am attaching dmesg pertaining part, when activating Wifi and my HW status via the (slick!) command inxi -Fxxxz
    I am uncomfortable rebooting on 5.3.18 as of now but i can provide analogous outputs and make tests, in requested. (I hoe I chose the corret formatting for forum post...)

    When using wifi and breaking it, both iwconfig and rfkill list show no Wifi (wlan0). Machine is a laptop, Dell Inspiron as you can see below.

    My idea is that on kernel-firmware some recent (?) pacthes/commits have broken Intel Wifi support upstream (p.s. bluetooth has been disabled on BIOS btw)

    Hi,

    Although I'm not familiar with Dell products running Linux,
    The following is more or less my SOP setting up machines from other manufacturers (primarily HP)...

    The first thing I noticed about your system is that although its hardware architecture is not latest, it's currently sold by Dell so considered "modern and supported."
    If this is a relatively new purchase, the first thing I do is look up whatever OEM resources are available on the OEM website for the machine.
    The following seems to apply to your model laptop and SLES (which for our purposes is close enough to set up openSUSE)

    https://www.dell.com/support/content...ems/suse-linux

    If necessary, go on the Dell forums and look for threads about openSUSE or ask questions specifically about your model laptop.
    You're primarily looking for any special OEM supplied software, monitoring and updating apps, and OEM drivers which might be specific to Dell hardware which might have been modified from what is standard and supported by the Linux kernel.

    Maybe do an Internet search on your hardware. In particular, verify your networking hardware with lsusb and lspci commands. If you've verified your problem didn't exist in whatever kernel was used in 15.0, while running the system verify that your hardware was identified the same and what driver was used (verify iwlwifi). Be certain what kernel contained the driver that works for your hardware.

    You can post if you have more questions,
    Otherwise, if after all of the above you're convinced that you've corralled the problem, collect the details and post a bug at our bugzilla https://bugzilla.opensuse.org

    What happens if, you enable Bluetooth in the UEFI/BIOS?
    • The Bluetooth and WiFi are sometimes combined into a single semiconductor unit …

    Are you certain that, there isn't a UEFI/BIOS setting which has also disabled the WiFi?

    Hello,
    my wifi is not Intel, and the same thing happened to me ... In my case I switched to Tumbleweed, as it is impractical to use the cable on this machine.

    @Luca
    You have not the same Hardware as the one who asks here.
    Please open a new thread.

    Hi everyone,

    sorry for delay. I have been trying MANY things before writing back. Actually I am possibly more confused than before and still NOT WORKING.

    I will anticipate that certainly something is gone WRONG with Intel Wifi recently because looking around the net in various bugzillas and posts I see an uprising of iwlwifi/Intel wireless problems, non necessarily by 3160.

    @TSU
    My machine has not and OEM Suse installed. Opensuse was installed afterwards as the only OS.
    I tried looking anyway at Dell site but nothing useful.

    I made a openSuse 15.0 LIVE USB Stick and tried Wifi. With 15.ZERO, it is working.

    If I reboot into 15.2..I tried many things. the latest Kernel 5.10.rc2 from Suse and firmware. No joy.
    I also tried latest openSuse 15.2 kernel (.137) currently used by machine and zypper dup (showed only kernel packages and timezone in update list)
    Kernel and firmware, NOT working with Wifi, now are:

    Code:
    Linux linux-iotd 5.3.18-lp152.137.g1977cb0-default #1 SMP Wed Nov 4 09:13:48 UTC 2020 (1977cb0) x86_64 x86_64 x86_64 GNU/Linux
    and after zypper dup on 137 firmware version looks to be 20201023-338.1

    i will say that currently loaded version of iwlfiwi (from dmesg errors) is ... 17.3216344376.0

    @ dcurtisfra
    You had a nice intuition about bluetooth... unfortunalety in BIOS the settings are splitted..si WiFi and Bluetooth have their own switches... (there are 2 switches... for 2 settings.. one for "Wireless Device Enable" (WLAN/WiGig and BT separated ) and one for "Wireless Switch" (WLAN/WiGig & BT separated)
    In one of my many attenpts... flipping on and off those 4 switches... made me have Wifi for almost FIVE minutes (pinging).
    Obviously this is ridicolous..but was my record..because usually Wifi crashes in 20/30 seconds... so..somehow useful note.



    @Sauerland


    the output you request is..difficult to manage because.. sometimes shows something, sometime not..sometimes, things differ...

    Anyway..at the moment, after rebooting, trying wifi with Bluetooth ON/Enabled and crashed wifi, output is:

    Code:
    rfkill list all 
    1: hci0: Bluetooth 
        Soft blocked: no 
        Hard blocked: no
    Before (BT off and immediateli after booting and Wifi not enabled in Gnome but.."loaded")

    Code:
     rfkill list all
    0: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no




    I paste a "current" dmesg piece... even if.. it depends on what actions have been taken (wifi scan..turn off, turn on..etc)

    I have also tried (hopefuly done well..) to install OpenSuse 15.2 Kernel back to "19" (also tried "33")..now on 137..but.. still problem..

    I repeat what I said at the beginning
    "I made a openSuse 15.0 LIVE USB Stick and tried Wifi. With 15.ZERO, it is working."

    I don't know what's happening on Intel hardware (wireless) but..something is definitely going on (and slipping into backports too..)

    I am wondering if..contacting linux-wireless group ..would be helpful..

    As per suse bugzilla... yes..I could make an entry..even if I see that Wifi/Intel troubles are already poppoing up (eg https://bugzilla.opensuse.org/show_bug.cgi?id=1178271 , https://bugzilla.opensuse.org/show_bug.cgi?id=1178284 )



    Any ideas, fellows ?

    Bye!

    Drivers attempts to dump hardware error log. Try removing (renaming) all firmware files for your card that were not present in 15.0. This will force driver to load the older firmware. To verify that it is not firmware issue.

    @arvidjaar

    hmm..interesting idea...

    I'll look into it.

    Unfortunately I added another variable to the equation.. I've overwritten my "old" USB key with a LIVE suse 15.0..but
    after many minutes of usage (booted from Live)... I experienced wifi errors again

    So... the awful idea that some HW got broken resurfaces... but.. there is also the possibility that OpenSuse Live distros get updated even if version is old ...

    Also I have to factor in a couple more things... Bluetooth settings/status (including Bios) seem to be influencing.
    And.. about your suggestion..I had a quick look.. and firmware for 3160 seem to be the same numbering (max is 17...) but... also seems that there is a new format.. .xz
    XZ..means binary is compressed... so... I have a few things to try out.

    Thx!

    In a few other threads, ventoy has been mentioned as a recent new alternative for creating a USB stick.
    Diff is that with ventoy...

    You don't write image contents to the USB key,
    Instead ventoy will automatically detect the image files you've loaded on your USB key and if more than one automatically creates a menu for you to choose,
    Then the image file you select is mounted.

    Assuming you have enough space on your USB key, you'll be able to load multiple Live images instead of wiping and burning new images to your USB key each time.
