    Exclamation Incorrect Intel 3165 driver status in Software&Updates on dual boot Ubuntu 20.04

    Hi, Ubuntu community.
    I've got an issue with the wifi card(Intel Wireless AC 3165) drivers detection on Ubuntu 20.04:
    though the device is able to provide internet connection and is powered on(and even has kernel module loaded),
    the "Software&Updates" tab "Additional Drivers" is showing "The device is not working" message near the "Intel Corporation: Wireless 3165" driver.

    Here's the prerequisites:
    1. I've installed Ubuntu 20.04 on my Dual-boot notebook Dell Inspiron 7559 with Windows 10 default OS.
    2. After starting to check the system default drivers, I've noticed this error inside "Software&Updates" UI application's tab "Additional Drivers" - Intel Corporation: Wireless 3165; The device is not working.
    3. After starting to investigate deeper into the issue fix(and into kernel/drivers of Ubuntu 20.04, which I'm newbie in), I haven't found any EXPLANATION of this message NOR the reason for it, according to current system kernel's driver details output

    Question1: Why the driver status inside "Additional Drivers" tab is "The device is not working"(screen.jpeg), but the Wi-Fi connection is working correctly and the module is loaded into kernel?

    According to this I need a help regarding specifics of Dell+Intel Wifi <-> Ubuntu Kernel(Modules, Drivers) loading/unloading/troubleshooting.
    My assumption is that the driver is working correctly, but the "Software&Updates" have some BUG or incorrect driver status detection, related to Intel Wi-Fi card and Kernel/OS.

    Here's why.
    My setup:
    - Kernel version(`uname -r`): 5.4.0-31-generic
    - OS: Ubuntu 20.04 LTS Desktop
    - Wifi card - Intel 3165AC + BT4.2 [802.11ac + Bluetooth 4.2, Dual Band 2. 4&5 GHz, 1x1]
    - Video: NVIDIA GeForce GTX 960M+Mesa Intel® HD Graphics 530 (SKL GT2) # posting it due to *(see ref. 1 below)

    What I've already check:
    1. According to Intel driver recommendations(1) and kernel compatibility docs(2) the supported versions of driver are:
    - iwlwifi-7265-ucode-25.30.14.0.tgz # with 7265-14.ucode inside. compatible with kernel 4.2+. archive downloaded from www.intel.com table's link(1)
    - iwlwifi-7265-ucode-16.242414.0.tgz # with 7265-16.ucode inside. compatible with kernel 4.3+. archive downloaded from wireless.wiki.kernel.org table's link(2)
    which I've prepared for setup.
    1.1 But before that, I've checked this tutorial related to 18.04 issues, which solves the issue by updating HWE & AC according to Official Ubuntu LTSEnablementStack or by updating kernel.
    According to this tutorial, I've:
    >sudo apt-get install linux-generic-hwe-20.04 # though it's already included in 20.04 LTS
    >sudo apt-get install xserver-xorg-hwe-18.04 # for 20.04 this is the latest version of X(<- using search)
    BUT THE ISSUE REMAINS even after reboot.
    1.2 According to Ubuntu 20.04 shipped drivers 7265-*.ucode even newer one(iwlwifi-7265-17.ucode) IS ALREADY present by default:
    > ls -l /lib/firmware/iwlwifi-7265-*ucode
    Code:
    -rw-r--r-- 1 root root  736844 бер 19 18:37 /lib/firmware/iwlwifi-7265-10.ucode
    -rw-r--r-- 1 root root  880604 бер 19 18:37 /lib/firmware/iwlwifi-7265-12.ucode
    -rw-r--r-- 1 root root  885224 бер 19 18:37 /lib/firmware/iwlwifi-7265-13.ucode
    -rw-r--r-- 1 root root 1180412 бер 19 18:37 /lib/firmware/iwlwifi-7265-17.ucode
    -rw-r--r-- 1 root root  690452 бер 19 18:37 /lib/firmware/iwlwifi-7265-8.ucode
    -rw-r--r-- 1 root root  697828 бер 19 18:37 /lib/firmware/iwlwifi-7265-9.ucode
    which should be good, but is more strange.

    2. my current network hardware output is:

    and rebooting, THE ISSUE STILL REMAINS.

    Question2: If the fix with "Additional drivers" tab doesn't relate to kernel drivers, are there any possibility to switch radio-button to "Continue using manually installed driver" and enable "Apply changes" button?

    (*) Ref. 1: nVidia/Intel video cards(discrete&integrated one) are working on stock drivers(nvidia-440 proprietary&Mesa with i915 kernel module respectively). Also cuda 10-2 metapackage(for 18.04 as for now) is installed and tested by running samples(though with minor build issues) successfully.
    This info is "for general information" regarding another drivers, which operates better. Please take this into account if that is necessary.

    firmware was replaced in firmware folder.

    Why 14th *.ucode file wasn't loaded by firmware?
    Should *ucode files be loaded using special procedure? Eg: using special runlevel or with additional files or by stopping wifi/unloading module?
    According to this docs(FOR ANOTHER intel wifi card), see Section "Files Copied to Root", the additional *.ko file should be supplied with Intel card - /lib/modules/<kernel_version>/updates/iwlwifi.ko
    But current /lib/modules/5.4.0-31-generic/kernel/drivers/net/wireless/intel/iwlwifi/iwlwifi.ko do exist.

    My assumption is that the driver is working correctly, but the "Software&Updates" have some BUG or incorrect driver status detection, related to Intel Wi-Fi card
    Yes, indeed, it is a bug. You may safely ignore it. As you noted, your wireless is working properly and so there is no need to “fix” it.

    You can fiddle with the firmware all you want and you can’t and won’t change Additional Drivers; you might, however, stop your wireless from working.

    Re: Incorrect Intel 3165 driver status in Software&Updates on dual boot Ubuntu 20.04

    I wrote the above post from my bedroom and the response was short. I now have other observations.

    First:

    iwlwifi-7265-ucode-16.242414.0.tgz # with 7265-16.ucode inside.
    And it also has 7265D inside. That's entirely consistent with the link you gave which says:

    Those devices will not be supported by the newest firmware versions: the last firmware that was released for 3160, 7260 and 7265 is -17.ucode. Bug fixes will be ported to -17.ucode. 7265D, 3165 and 3168's latest firmware version is -29.ucode. In order to determine if your 7265 device is a 'D' version, you can check the dmesg output:

    Detected Intel(R) Dual Band Wireless AC 7265, REV=0x210
    The revision number of a 7265D device is 0x210, if you see any other number, you have a 7265 device.
    And you have:

    Detected Intel(R) Dual Band Wireless AC 3165, REV=0x210
    Therefore, the latest firmware for your device is not the old iwlwifi-7265-17.ucode but, instead, the newer iwlwifi-7265D-29.ucode. In fact, the version number -29 corresponds to what is actually loaded:

    loaded firmware version 29.1654887522.0 op_mode iwlmvm
    Also:

    sudo cp ~/Downloads/iwlwifi-7265-ucode-16.242414.0/iwlwifi-7265-16.ucode /lib/firmware/
    In later Ubuntu versions, starting at 20.04, firmware is at /usr/lib/firmware. Please recheck your location.

    The iwlwifi driver looks at pci.ids, which you can find with:

    Code:
    lspci -nnk | grep 0280
    As an example, here is the data from my machine:

    Code:
    03:00.0 Network controller [0280]: Intel Corporation Wireless 7260 [8086:08b2] (rev 83)
    So the driver, seeing a pci.id, 8086:08b2, for example, that's included therein, loads and then looks for firmware. Finding the appropriate firmware, it creates a wireless interface, Network Manager uses it to get a connection and everything is then working as expected.

    However, none of this at all is going to fix the bug in Additional Drivers. You are encouraged to find and add to the bug report here: https://help.ubuntu.com/community/ReportingBugs After that, I recommend that you do what I do: ignore it and enjoy your wireless.

    I do congratulate you on your thorough investigation into the mysteries and vagaries of Intel wireless firmware! It is mostly correct but wholly unrelated to the bug.

    Re: Incorrect Intel 3165 driver status in Software&Updates on dual boot Ubuntu 20.04

    and wifi is on(using which I'm writing this post ):
    > iwlist wlp5s0 power
    Code:
    wlp5s0 Current mode:on
    In this context, Power:on refers to power management; that is, the ability of the device to power down when not under a load and, most crucially, to power back up properly when needed. Learn more from the terminal command:

    Code:
    man iwlist
    power
    List the various Power Management attributes and modes of the device.

    1) Do you assume it the same as I do?
    or
    2) Does that mean than Intel drivers are missing implementation of generic functionality required from "Additional Drivers" ui window "presenter"(see MVP) side or from inner dependency - library/shell/kernel api/"driver management system design"?
    Or do "Additional Drivers" window implementation is lack of code-base update due to further-released improvements from driver dev team or inner dependency?
    Or in short: "What component in this OS feature is lack of dependency update?"

    I would appreciate if you share a shell command for that or any other TLP like utility(which I'm investigating now ) for that task, as currently I've only googled this SE's answer, which seems not solve the issue(powersave != poweroff).

    Because it is incorrect for your 0x210 device, as I said and as a link you gave in your original question clearly shows.

    Why do you suppose that turning off power management proves that there is a bug in the Additional Drivers utility? I do not. However, if you'd like to test:

    Code:
    sudo iwconfig wlp5s0 power off
    Verify:

    Code:
    iwconfig
    You should see something like:

    Code:
    wlp5s0    IEEE 802.11  ESSID:"my_lil_router"  
              Mode:Managed  Frequency:5.745 GHz  Access Point: xx:xx:xx
              Bit Rate=866.7 Mb/s   Tx-Power=22 dBm   
              Retry short limit:7   RTS thr:off   Fragment thr:off
              Power Management:off
              Link Quality=55/70  Signal level=-55 dBm  
              Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
              Tx excessive retries:0  Invalid misc:494   Missed beacon:0
    Did that magically fix Additional Drivers? I don't think so.

    which seems not solve the issue(powersave != poweroff).
    Why do you want to turn power management off at all? Is your card not recovering from idle periods properly? My Intel does and I think it is a useful feature particularly on battery power.

    "What component in this OS feature is lack of dependency update?"
    I'm not a kernel developer nor a driver developer. I don't know what the root problem is. If I did, I'd have already submitted a patch to fix the bug and fielded a juicy job offer from Intel.

    Re: Incorrect Intel 3165 driver status in Software&Updates on dual boot Ubuntu 20.04

    In this context, Powern refers to power management; that is, the ability of the device to power down when not under a load and, most crucially, to power back up properly when needed.
    Thanks a lot for update and sharing a knowledge. In general I wanted to show that the wifi card is enabled, without knowing the better way to do that.
    But in general regarding this update - in the next post, which I've wrote after your observations and further update(without checking the update ), I've mentioned that

    powersave != poweroff
    as a warning. By this I wanted to note, that powering off isn't possible by switching power management to "off" (of course if you aren't' going to trigger power-off somehow(in powern mode) by DDOSing a card or by disabling it and make a candidate for powering off ).
    At least from my knowledge perspective


    Because it is incorrect for your 0x210 device, as I said and as a link you gave in your original question clearly shows.
    Just check the possibility to load 7265D-16.ucode driver and get the error:

    Why do you suppose that turning off power management proves that there is a bug in the Additional Drivers utility? I do not. However, if you'd like to test:
    To be short, by this I want to check whether the "switching-off-by-software-turn-off"(<-by this I mean to physically pull of a card, which isn't worth it and easy task for this case) would cause a message "The device is not working" to disappear from tab,
    but by "causing a disabling of a driver if the device isn't connected" and therefore to proove that this label is based on the driver-driven-logic-in-ui-presenter, but not due to other side-effect.

    Super! Thanks a lot for this link - this is just what I've been googling for without knowing the right place

    Just post a comment with a link to this thread

    If the fix with "Additional drivers" tab doesn't relate to kernel drivers, are there any possibility to switch radio-button to "Continue using manually installed driver" and enable "Apply changes" button?
    Am I understanding right, that this is also makes not a lot sense in comparison to waiting to bugfix release?
    Will the 7265D-16.ucode(the lower version) driver be detected as manually installed?

    No, I strongly doubt that any action that you or I as users can take will cause a message "The device is not working" to disappear from the tab. As I've said several times, it is a known bug.

    Powering off the card, which you can easily do with the wireess switch or key combination, is an entirely different operation than power management, the mechanism that reduces power, but not to zero, when the card is momentarily inactive and restores it again upon new activity. Turning the radio down is not the same as turning it off.

    Please try the airplane mode switch on your laptop and tell us if the message "The device is not working" has disappeared from the tab,

    Again, it's a known bug. We don't know the reason.

    Will the 7265D-16.ucode(the lower version) driver be detected as manually installed?
    The firmware is a different thing from the driver iwlwifi itself. In the context of the tab that bothers you, it refers to the driver iwlwifi, not the firmware. The version of the driver that you and I have is written for specific firmware versions and none other as you've discovered:

    [ 6182.451722] iwlwifi 0000:05:00.0: minimum version required: iwlwifi-7265D-22
    [ 6182.451723] iwlwifi 0000:05:00.0: maximum version supported: iwlwifi-7265D-29
    You have and load -29 if you haven't over-written it.

    Please try the airplane mode
    The message still persist.

    load -29 if you haven't over-written it.
    I've restored them from backup after failed v16 and renamed to v22 load. They're working now.

    The firmware is a different thing from the driver iwlwifi itself.
    I agree. Here we're loading a firmware which contains iwlwifi/iwlmvm drivers(which interact with hardware firmware).
