Intel AX210 M.2 Wifi Card Module TX Power issues Orin NX

[SeanKelly]

Hi, I am checking for possible assistance with what appears to be a power management issue.

• Orin Nano NX 8GB
• Jetpack 5.1.2 L4t 35.4.1
• Ubuntu 20.04
• Intel AX210 M.2 Wifi Card Module

I have the exact same set up on the Orin Nano 8GB and it works floorlessly, I have done a lot of debugging and trying to understand where the issue lies, it appears there may be a power management issue, the Tx-Power screenshot has been placed below, it has a very weird negative value, I have done all the checks regarding antenna, I have tested different power modes on the orin nx and have ensured the power supply is appropraite. When mirroring the exact same settings for the Orin Nano 8GB it works. Has anyone encoutered this issue or able to provide advice on how to amend, thank you.

Hi SeanKelly,

I understand that you are experiencing negative value for the Tx-Power. Please allow me to further assist you with this.

First, I would like to set your expectations by saying that I am going to ask a series of questions to narrow down the recommendations I could provide. If you may, kindly share the following details below:

For the record, what is the exact issue you are experiencing with your Intel AX210?

1. When did the issue start?
2. Were there any recent changes that happened on your system?
3. Just to confirm, is your operating system fully updated?
4. What frequency are you are using to connect to your access point?
5. You mentioned that you multiple test. Please specify the test you've done.

Furthermore, I hope that you download and install an Intel tool that will scan your system. Don't worry; there will be no personal information to be collected. To get the tool, please visit this link: https://www.intel.com/content/www/us/en/download/18377/intel-system-support-utility-for-windows.html

Please run the program, select everything, then scan, click next, save the result log, and upload the text file in your next response.

I will be waiting for your response.

Hi Brian

Thanks for your response, I managed to resolve it by doing the following

# Install backported wifi
git clone https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-iwlwifi.git
cd backport-iwlwifi
make defconfig-iwlwifi-public
make -j$(nproc)
sudo make install
sudo reboot


# Update other stuff
git clone https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
cd linux-firmware
sudo cp iwlwifi-ty-a0-gf-a0-*.ucode /lib/firmware/
ls /lib/firmware/ | grep iwlwifi-ty
sudo update-initramfs -u

# reboot
sudo reboot

# connect and then you can view connection with below
nmcli conn show

# Optional **
# On occassion requires a specific install of this file
sudo wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/iwlwifi-ty-a0-gf-a0.pnvm -O /lib/firmware/iwlwifi-ty-a0-gf-a0.pnvm
