No support for Intel Killer AX1675i

[Marcos Alano]

I just installed a Intel Killer AX1675i Wifi+Bluetooth card in my Dell G15 5511 laptop but can't get WiFi or Bluetooth.
About WiFi I get these logs:
➜ sudo dmesg|grep wifi -i

I'm in doubt about WiFi, since the message doesn't mention a missing firmware, but Bluetooth is very clear about it.

I'm using Ubuntu 22.04 LTS with bleeding edge kernel 5.17.4. I also tried with 5.18rc1 but no change

I loaded the iwlwifi module with debug=1 option to get more details. I hope it helps

Work Around
Tested in Ubuntu 22.04 (5.15.0-33 generic)

Important note : Disable secure boot

Compile a driver for AX1675i from Intel's instructions

Step 1 – Download the Latest Git and Build-Essential packages

$ sudo apt update
$ sudo apt-get install -y git
$ sudo apt-get install -y build-essential

Step 2 – Download the Iwlwifi-Firmware.git repository

$ git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
$ cd linux-firmware
$ sudo cp iwlwifi-* /lib/firmware/
$ cd ..

Step 3 – Create the Backported Iwlwifi Driver for your current setup

$ git clone https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-iwlwifi.git
$ cd backport-iwlwifi
$ sudo make defconfig-iwlwifi-public
$ sudo make -j4
$ sudo make install

This command might be necessary to force your machine to use the Driver from boot:
$ update-initramfs -u

[Juerg Haefliger (juergh)]

There is a backport-iwlwifi DKMS in the archive. Can you test that and post the dmesg output?

$ sudo apt install backport-iwlwifi-dkms

[Marcos Alano (mhalano)]

I think this bug will be open forever. I replaced the ax1765i card per an ax1675x card that works now on my laptop. Maybe another affected person can test that.
The problem was: there is no PCI ID in the driver's source code for my card. I thought it could be counterfeit. One test I did: I added manually the PCI ID to the source code and recompiled the driver. It _seems_ to work, detecting the card, but there was no firmware available to load in that case.

[Juerg Haefliger (juergh)]

Hence using backport-iwlwifi which might/should support it.

[Juerg Haefliger (juergh)]

@harish-kp Yours is a different problem. Can you open a new bug for that?

$ ubuntu-bug linux-firmware

[Juerg Haefliger (juergh)]

The HW (43f0/1672) of the bug reporter is not (yet) supported by upstream.

[Juerg Haefliger (juergh)]

@harish-kp please do not hijack this bug report. Your problem (whatever it is) is a different one. Please open a separate but report for that.

[Juerg Haefliger (juergh)]

This card is still not supported by upstream. There's not much we can do until that happens.

Hello everyone

I was also getting the following error:

```
Bluetooth: hci0: Failed to load Intel firmware file intel/ibt-19-0-3.sfi (-2)
```

I have noticed that the `ibt-19-0-3.sfi` file is not present on the system. As I was unable to find it anywhere on the Internet, I did the following:

```
ln -s /lib/firmware/intel/ibt-19-0-4.ddc /lib/firmware/intel/ibt-19-0-3.ddc
ln -s /lib/firmware/intel/ibt-19-0-4.sfi /lib/firmware/intel/ibt-19-0-3.sfi
reboot
```

After that, my bluetooth started working! (as far as I can tell, I've just done it, cannot tell you anything about stability)

I hope it helps!

[Juerg Haefliger (juergh)]

This is a completely different problem. Please open a new bug by running 'ubuntu-bug linux-firmware'.
