Intel Nuc WiFi Issue

Product support
1

We’re working with a Nuc device and have followed the Resin instructions (https://docs.resin.io/installing/gettingStarted-NUC/#setting-up-your-device) and although ethernet works great,we have been unable to get WiFi to work with the installed image.

I’m noticing your instructions mention “WiFi adapter”… but the Nuc’s documentation says:

The NUC7i3BNH comes with Intel 802.11ac wireless, Intel’s fastest wireless available today, for connectivity right out-of-the-box.

Has anyone else seen similar issues and any suggestions for fixing?

Hi. This PR should solve your problem:

https://github.com/resin-os/meta-resin/pull/663

If you are in a hurry to have the fix before it gets into a new release, then just let us know and we will guide you through adding the firmware manually to your install USB stick

Great! Yes, if you could send instructions on adding the fix to the USB stick that would be great.

The file you should copy is from this git repo: git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git

So first clone the above git repo.
Then copy the file iwlwifi-8265-22.ucode you find the newly cloned directory over to the USB stick, in the /lib/firmware/ directory.
By doing so, you should be able to see the device on the dashboard when you provision a new device.
Do these steps for the moment and let me know if you can see a new device provisioning in the dashboard when you use the changed USB stick as instructed above, without and ethernet cable plugged in.

If this works okay, I will then guide you through the rest of the process so as your wifi will keep working after you re-power-on this newly provisioned device.

There wasn’t a /lib/firmware directory on the USB so I created one and added the file.

Unfortunately, this didn’t cause the device to show up in the Resin dashboard however

Odd. There should be such a directory.
What is the resin.io OS version you are using? And just to confirm, you downloaded it from the resin dashboard, right?

We figured out the /lib/firmware issue - just had to mount it on a Linux machine. We now see the device as “Post Provisioning” in the Resin dashboard - so I think we’re ready for the next steps!

Great then. For the next step, you should inspect your USB stick and check to see there about an .img file in the /opt/ directory. You have to loop mount that, copy the same firmware there, unmount it and that should be all.

Linux commands for loop mounting it:

$ sudo losetup --show -fP

This command should return a loop device, something like loop2 for example

Then

$ sudo mount /dev/loop2p2 /mnt/

Then copy the firmware file to /lib/firmware/

Then

$ sudo umount /dev/loop2p2

$ sudo losetup -d /dev/loop2

Then unmount the USB stick and try again now. You should now have wifi connectivity when you provision and after you re-power the board post provisioning

Worked! Thank you!

Just to be clear, this will be integrated with the next Resin OS release?

You’re welcome. Glad to have been able to help.
Yes, the firmware you need will be available in the next resin OS release

I think issue remains , the following errors are found into dmesg:

[ 3.698543] iwlwifi 0000:02:00.0: Direct firmware load for iwlwifi-8265-24.ucode failed with error -2
[ 3.698549] iwlwifi 0000:02:00.0: Direct firmware load for iwlwifi-8265-23.ucode failed with error -2

looking to /lib/firmware , those files don’t exist.

There are the following older version though:

iwlwifi-8265-21.ucode and iwlwifi-8265-22.ucode

Are you having issues with the wifi on your NUC because of these versions?
